How to saw correctly on a formatting machine

How to saw furniture board without chipping. Sawing laminated chipboard at home. Selection of circular saw blades and saw blades

And also for sawing will need additional tools:

Cutting Laminated chipboard is done in the following order:

• Marking out the material. A ruler and pencil are needed to mark out the workpieces, in order to mark dots on the sheet of material at the end. Then the dots must be connected evenly in one trimmer line and a masking tape must be glued on top. A good way to saw laminated chipboard without splitting is with the band. к. It helps reduce the number of cracks in the sheet material that occur due to increased temperature and high pressure. Sawing Laminated chipboard.
• Then the sawing process Laminated chipboard. We choose what to saw Woodchipboard, and put the tool at the required angle, so that the sawed edges of the sheet were even. Sawing Laminated chipboard and chipboard should be done as gently and as smoothly as possible.
• Board processing. If the sawn particleboard at home is uneven on the cut ends, they are machined with a belt sander. In some cases it is better to immediately contact a company that provides services for the production of furniture parts to order according to the size of the customer and sawing Laminated chipboard on special equipment. To veneer the edges of the parts, a special veneer end edger is used for processing.

Precision and quality

Formal cutting machines for sawing Laminated chipboard and particle board have a high quality of cut, which reduces the subsequent costs for the processing of cuts (sanding, removal of chipping and burrs, etc.). That’s why these machines can cut any complexity and configuration, which means almost unlimited possibilities in furniture production. Fancy children’s furniture, comfortable computer desk tops, carved curved decorations in the doors of kitchen fronts. all this is possible with the machines.

There are two types of panel cutting machines:

• vertical, which is a strong rigid vibration-resistant welded bed (frame), set vertically with a tilt to the back by 50°, with guides located at the top and bottom, on which the saw beam moves. It is the arm for the saw unit, which slides up and down along the beam and rotates through 90°, so that both vertical and horizontal cuts can be made. Cutting precision is amazing. For sawing laminated chipboard as well as hard, corrugated or porous boards a special scoring unit is used. The saw blade rotates at up to 15,000 rpm;
• horizontal, consisting of a table for the plate, a carriage to move the saw along the sawing mechanism and the sawing mechanism itself, consisting of one or two cutting units. The cutting units themselves are equipped with a main saw and a scoring saw. The principle of operation is simple: the main saw cuts deep into the chipboard and the scoring saw precisely and accurately cuts the bottom edge (veneer or laminate surface). Saw unit can also be tilted up to 45°.

The mitre saw is a homemade and greatly reduced copy of a horizontal machine. It can not cut a wide sheet of chipboard or laminated chipboard, but it can cope with small parts.

Cherish the diamond trim as a diamond hanger

For qualitative work of the main saw on a panel cutting machine with manual feed, used for cutting boards and especially laminated (faced) materials it is necessary to use an auxiliary saw for undercutting the bottom plate of the workpiece. This saw, which is mounted on the scoring unit of the slicing machine, is called a scoring unit and is mounted before the main saw blade. It rotates as the workpiece moves and operates at higher rotational speeds than the main saw. Its main task. Slot 1-2 mm in depth and 0.2 mm in width to the kerf of the basic saw. This “ahead of the curve” cutting ensures that there are no splinters in the subsequent sawing of the main unit. Trimming saw for a format machine can be of two types: sandwich (made of two saw halves) and one-piece saw with conic tooth form.

Sandwich scoring saw. Lightly split design consisting of two saw halves connected by dowels. A set of spacers of different thicknesses is included with this saw. 0.1 to 0.5 mm in assortment, which are installed between the saw halves. These spacers are assembled so that the assembled saw provides a kerf thickness of 0.2 mm thicker than the tooth thickness of the main saw. As the main saw is worn and sharpened it is also necessary to adjust (reduce) the thickness of the undercut, which is achieved by the selection of spacers. As a rule, the number of teeth on a scoring saw is 24. (12 teeth on each half). Cutting tooth shape can be alternately beveled or rectangular. There is no fundamental difference in the use of these tooth shapes, but when sawing with a tool with alternately beveled teeth high quality can be achieved at a small penetration of the saw, and the straight tooth is used in cases when it is necessary to penetrate the undercutting saw to a greater depth, for example, due to large height differences of the bottom plate due to distortion of the plate plane because of its improper storage.

Diamond saw tooth wear

The one-piece scoring blade is designed for the same purpose of undercutting the cladding layer of the underside of the board before the main cutting tool passes through. Trim thickness adjustment is performed by raising or lowering the trimmer unit. The kerf of the saw blade changes due to the conical tooth shape at different kerf settings and the kerf width should always be 0.2 mm greater than the width of the main saw blade.

One-piece undercutting blade is usually used on format saws for cutting short workpieces, e.g. popular machines with a standard carriage of 3200 mm, but always with a pneumatic pressure beam along the entire length of the cutting plate, which guarantees perfect clamping of the workpiece to the machine carriage, which ensures continuity and a uniform kerf even with a poor quality “floating” plate.

Inspect diamond saws for cracks, chips or burns on the body, or any other damage before operating the machine. Do not use this saw even if they are suspected. Damaged, incorrectly mounted or badly worn saws can cause a production emergency.

If you suspect that a defect in the saw has occurred, such as a buzzing noise when you start work on it, please return the saw to your supplier with an explanation of the problem. Defective saws will be repaired or replaced after testing and troubleshooting. If the equipment and cutting tool are not working properly, the saw will be repaired or replaced at the user’s expense.

The diamond tool must be carefully and accurately installed on the spindle. The flanges (saw washers), their mounting surfaces and the saw shafts (spindles) must be clean and run without noise and vibration. Fasten the saws securely in their flanges and check for runout with a watch-type indicator on the magnetic stand before use. If possible, check for runout of the saw shaft and if so, the diamond saws should not be operated on this machine until all problems have been corrected.

Flanges for undercutting saws on the machine should be about 1/3 of the undercutting diameter. The working surfaces of the flanges must be free of rust, resin or adhesive residue, dust and handling defects (burrs, potholes, etc.). п.). The blade must rotate perfectly straight after it is clamped in the saw washers. The diameter of the flange affects the stability and quality of the diamond saws. In ultrafine diamond saws the flange diameter should be 3/4 of the saw’s diameter. As a general rule, use the flange of the largest possible diameter.

Always wear safety shoes, close-fitting clothing, safety glasses, earplugs, hard hat and face shield. Never remove the original protective guards on the machines.

Before using a diamond tool, make sure the arrows on the saw point in the same direction of rotation as the shaft, which will ensure good results and longevity of your blade. Allow the saw to idle for a few seconds before starting any operation. If the saw trembles, vibrates or makes other noises, stop work immediately and turn off the machine. Inspect the cutting tool for damage or check that it is correctly installed.

It is very important that boards and blanks to be cut, especially long ones (over 1000 mm), are firmly clamped during cutting on hand feed saws (mainly diamond sandwich saws with a diameter of 80-120 mm) against, for example, a guide rail or the saws must be equipped with clamping devices (beams). Otherwise the diamond saw blade may break during the sawing process, even with a slight deviation of the kerf from the cutting axis, or the lateral cutting edges on the saw teeth may start to wear down intensively due to increased friction. This is especially the case with sandwich saws because of the construction of the body (see Pic. figure).

Saw blade speed on such machines is usually 3000-6000 rpm and can be adjusted depending on the diameter of the saw and the material. Optimal cutting speed should be 60-100 m/s, depending on the diameter of the saw. Feed speeds for machines with manual feed are typically 5-15 m/min. In order to extend the life of the diamond saw and reduce wear, the saw has to be operated at the optimum cutting speed and feed rate. Increase the feed rate when cutting soft, unstable panel materials and increase the cutting speed when cutting hard, stable materials. reduce.

What tools can be used?

Hacksaw

This tool is used for good old-fashioned scoring method. It must be said that a good quality of cut with a hacksaw is difficult to achieve.

• First we scratch or cut the line for the trimmer measuring tape on the material with some stabbing-cutting tool (for example, a knife) and put a scotch tape on it. It is necessary so as not to damage the laminate surface.
• We guide the hacksaw to the material at an angle of 30 degrees and move it smoothly back and forth. Chips are sure to remain in this case.
• If there are any damages left by the hacksaw we need to go over them with a file (from the edge to the center).
• The final step is to process the cuts Laminated chipboard with sandpaper, so that there is no roughness.

The main advantage of the hacksaw is its accessibility and ease of handling, but it does not perform the function we need to prevent chipping, so we do not recommend its use.

Jigsaw

Electric jigsaw. this is the most popular solution at home, as the tool itself does not cost fabulous money, and therefore available to the average consumer.

Saw blades for sawing worktops with a jigsaw should be of small length (no more than 75 cm) with teeth of class A or B, suitable for Laminated chipboard.

When sawing with the jigsaw, you need to make smooth movements with the tool without pressure at a speed slightly above average. Chips are most likely to appear on the opposite side of the board from where the jigsaw teeth fit.

Chips appear on the back of the board in the process, and spoil the appearance of the piece. They can only be removed with a milling machine, which means extra work and material waste. So this tool doesn’t work for us either.

Circular saw

Circular (or circular) saw is another tool that can be used to make furniture parts.

To saw, you must mark the guide lines on the boards and clamp the saw to the board, but it is not guaranteed that the edges of the parts will be straight. Chips appear on the underside of the board in the process. And they can only be worked on with plastic profiles with clips on the ends Chipboard. But the circular saw. not the cheapest pleasure, and even with it you will not avoid chips, so in this case there is no point in overpaying.

Milling machine

Another option for sawing laminated chipboard is an electric tool for manual woodworking. It is used in combination with the jigsaw. The process looks like this: first saw Laminated chipboard with a jigsaw, a little deviation from the markings, and then with a cutter with a bearing, which deepens the cut to the desired level.

The main disadvantages of this tool is that it is not as common as, for example, angle grinder, and not everyone can find at home. Well, its use. it is a rather labor-intensive process, which can cope only qualified specialists, and beginners should not even approach it.

Slicing and shaping machine

The most accurate cut and a guarantee of absence of chips can provide only one tool. panel sawing machine, which belongs to the professional equipment. Since the machine is very expensive and is used mainly in manufacturing, amateurs usually can not afford it. The only good solution in this case is to call in professionals. Companies that specialize in sawing furniture parts usually use these machines in their work.

Formatting and sawing machines have the following settings, which are set depending on the length and width of the board to be cut:

The machines themselves are divided into the following varieties:

The components of a format slicing machine, which allow to ensure accuracy and absence of splinters in the production of parts:

• The bed is the stationary base of the machine, to which all other mechanisms are attached. The heavier it is, the better for the cut, since it eliminates the vibrations and oscillations that can interfere with the process;
• scoring unit. an element that pre-sawns the workpiece blank and serves to ensure that there are no chips at the bottom;
• The main saw serves for the final sawing of the board and is responsible for a clean cut without chips on top;
• work tables. there are only three of them. The first one is stationary and serves as a base for the trimming unit, the second one is mobile and it feeds the board to the disk and the third one supports the parts that are sawn off the board;
• The carriage is the part of the machine that enables the formatting table to move;
• stops and rulers. components whose main function is to fix the plate in the right position.

The design of formatting and cutting machines allows them to ensure such precision in sawing Laminated chipboard for furniture parts that no other tool can guarantee. In addition, this is the only way to completely avoid chips.

Rules to be respected while sawing

With the tools we have already learned, now move on to accessories that you will need.

The correct procedure for sawing Laminated chipboard looks like this:

• First perform the marking of the material. You do this with a pencil and mark the cutting points on the face of the laminated chipboard. After drawing all the dots, we connect them into one trimmer line and glue the adhesive tape on top of it. Saw Woodchip board with a laminated coating is best precisely with the use of adhesive tape, so that it reduces the number of cracks when splitting. They appear because laminated chipboard is subjected to high pressure when the temperature rises.
• Then we saw the board. To do this, set the selected tool at the right angle to ensure that the part has straight edges. The process itself should be smooth and accurate, without sudden movements.
• Finishing the board. If irregularities are left on the edges afterwards, they can be filed out. And the cut lines are processed with sandpaper.

Most often, amateurs overestimate their strength and take it upon themselves to saw details from Laminated chipboard, and then regret that they did not turn to professionals immediately. After all, a specialized company guarantees you ready-made parts for furniture without chips, made according to your drawing with accuracy to the millimeter. Besides the finished parts need to be beveled, which you can’t do at home, because this requires a professional beveling line for a trimmer, with the help of which experts process workpieces.

Sawing rules

First you need to choose a sawing method.

Be sure to carry out the following preparation (cutting):

• To protect the laminated coating of the board from damage during the work, you need to prepare masking tape or adhesive tape;
• For the marking of blanks. a ruler and a pencil;
• From the ends of the board mark the future cutting points with a pencil;
• To avoid the appearance of chips, you need to glue on the place of sawing with masking tape or scotch tape;
• After taping the tape, connect the pre-marking points with a pencil;
• Prepare sandpaper for the final cut lines.

The following rule is not related to preparation, but to actions after sawing, but it is common for any method: if you find roughness on the edges, they need to be processed with a file or rasp. Cover the cut edges with veneer with a veneer pattern similar to the laminate surface.

What not to saw with

Laminated Particleboard cannot be sawn with an angle grinder, also called an “angle grinder”. There is a high risk of injury when using this tool, especially with large-diameter blades. You can also injure yourself when you remove the tool guard.

Sawing machine options

There are 3 ways in which a vertical panel saw makes cuts in the material:

• saw feed on the material. the saws are positioned under the table;
• Saw feed to material. the saw is positioned above the table
• Material feeding on the saw. the saws are located under the table.

In the case of the saw feed on the material, which is located above the table, the motor and the cutting blades are mounted on the carriage. The carriage is placed on the runners, placed at the proper height, which allow the whole structure to be held and move, for cutting, on the plane of the table. Sled or guide rails, can be made of channel or heavy duty pipes.

The location of the saw under the table, which is fed to the material, also involves the presence of guides and the carriage moving along them. The advantage of this arrangement is that the dust collector system is hidden under the table and does not hinder the movement of large objects.

When the cut is made while the material is being fed into the saw, a powerful mechanism is required to move the plates. In this case, the carriage for moving is the table, with legs on rollers. It is worth noting that the design of such a sawing mechanism requires more space and has less capacity.

Design features

Performance and functionality of the formatting and cutting machine depends on its features of its structural elements, the main of which are:

• The movable carriage is a mechanism for moving the work table equipped with a steel guide for sliding the workpiece onto the saw blade and making a precise cut. It is equipped with an end handle and screws for unlocking and locking the device. The steel ball drive is designed to move the carriage on the machine guides. It has the appearance of a linear platform with a special ball cage.
• Bed. a framework for fixing the working mechanism of the machine. It has several threaded supports that are installed in the frame legs. This attachment allows you to adjust the horizontal level of the unit and ensures the smooth movement of the work table.
• The table is a solid plate with a rigid mounting on which the product is cut. It is made of durable and lightweight metal. aluminum with a special oxide coating that prevents abrasion and deformation of the surface during operation.
• Control panel with push-button mechanism for the adjustment of the sawing operation.
• Additional equipment can be represented by a suction hose for removal of wood dust, shavings and other production waste.
• Measuring ruler for longitudinal, cross, 90 and 450 cuts or flip stop.
• Disclosing blade, which is designed to prevent the back ejection of the product behind the saw blade.
• Adjustable guard that covers the saw blade.

The precision operation of the formatting and slicing machine is ensured by a complex construction mechanism, which shows high profitability thanks to the adjustment and calibration of its main working elements.

Saw unit

The saw unit is the central body of the package slicer and trimmer. It is a saw blade with two circular saw blades that are driven by electric motors installed in a special compartment.

The blade closer to the workpiece is called the scoring blade. To get a good, even cut without scoring or splintering, it is positioned in the same plane as the main saw blade, that is at a zero slope. Mechanism is equipped with setting elements for setting the scoring blade in its designed position. scoring saw rotates at approximately 8000 rpm. in the opposite direction to the workpiece, first cutting of the workpiece surface, preventing deformation of the workpiece.

The teeth on the saw blades have different shapes for high-quality cutting of the material. Trapezoidal teeth are designed for material removal. The straight or rectangular teeth are used to deburr the surface of the product.

Basic saw

The main saw blade is as follows:

Together with the undercutting blade the main saw performs material cutting, but has a smaller width. Its rotation speed is on average 4000 rpm.

To ensure accuracy, the main saw blade has a measuring ruler for longitudinal cuts.

riving knife secures deployed cut in open position. This is necessary to avoid unintentional ejection of material in case of clamping.

Features of sliding table

Scribe table (sliding table) is necessary for feeding sheet metal to the sawing assembly, so it has increased dimensions. It is fixed in the slots of the moving sleeve by means of set screws, locking washers and flat washers. It can be moved by means of a steel roller mechanism in the clamping rail of the table. For convenience, it is equipped with an adjustment knob that drives the sliding mechanism.

The circular saw is a professional sawing machine for cutting sheet metal. Therefore, such machines are classified in terms of production capacity:

• Lightweight. Such machines have a simple modification, no additional equipment. Characterized by small overall dimensions and lightweight construction. These mini slicers are designed for small workshops or unique production facilities, which work for no more than 5 hours.
• Medium. These machines are usually built for continuous operation of 8-10 hours. Such sizing and sawing machines are installed in terms of serial production, where the work takes place during one shift. Formatochno-sawing working body forming the machine, equipped with a moving table, dust extraction and other additional functions that simplify the production process.
• Heavy. They are industrial machines, capable of working more than two shifts. The format-cutting automatic center is advisable to operate in the conditions of multifunctional productions. CNC nesting machines are also used for manufacturing of differently shaped milled products. Such machines have a robust design and electronic control panel with a programmed system of operations.

Format machines for cutting sheet products have different technical parameters, which determine their production capacity, cost, availability of additional equipment and design features.

What parameters are worth paying attention to when selecting a machine?

When choosing a format-cutting equipment it is important to consider the amount of work to be performed, which will depend on the following characteristics:

• capacity of the main and trimming saws;
• length and depth of cut;
• design features of the saw unit and moving carriage;
• Additional functions and adjustment mechanisms;
• weight and dimensions of the machine.

What kind of equipment is chosen for production directly affects the final quality of manufactured products. Machine manufacturers take into account important technological features of processes in both large and small plants. Therefore, each unit is upgraded to the specific needs of production facilities.

The structure of the format-cutting machine

Bed

The main function of the bed. to carry the main units and assemblies. However, when choosing a formatting and cutting machine, you should pay attention to its rigidity and weight, because these features provide stability of the machine on a concrete floor. In addition, a rigid, solid base allows you to dampen the vibrations arising during the work.

The quality of the basic elements of the base construction and welds is of great importance, because later on you may encounter difficulties with the alignment of the carriage or the work table.

Pay attention to quality of welds, corners and edges of metal parts of the base. Unscratched burrs in the course of maintenance or repair operations can cause serious injury to machine operators.

Working tables of the formatting and cutting machine

The working surface of the format-cutting machine consists of the main stationary working table, movable working table and 1-2 auxiliary tables. Fixed work table is mounted on top of the bed, is made of cast iron and must have a polished, artificially aged surface that prevents damage to the laminated boards of panel materials. It can be equipped with auxiliary tables, made from less rigid materials, to support long and wide workpieces without bending them.

The sliding table that is fastened to the carriage and moves with and over the carriage, is designed as a rigid lightweight construction and must have additional possibilities for fastening the front ruler for cutting parts with oblique angles. When choosing a formatting-cutting machine, you should pay attention to the amount of deflection of the table arising from the movement of the carriage.

The width of the worktable remains the main parameter. The size of the left sliding table affects the ability to pre-roll full-size sheets either Particleboard or hardboard. On the size of the right stationary table with a lateral movable stop. the width of cut workpieces.

Slitter carriage

The quality of the nesting and the dimensional accuracy of the workpieces depends on the carriage. To facilitate the work of the staff it is made of light aluminum alloy. Depending on the type of bearings used, there are two basic types of carriages: ball and roller carriages. Ball bearing slides are less susceptible to adhesion of dust and dirt to the moving parts. Roller bearings withstand high loads for years.

When selecting a panel cutting machine, attention must be paid to the length of the working stroke and the ability to cut full-format panels Fibreboard, Fibreboard and Particleboard. Additional options from the manufacturer can be: manual or pneumatic clamping for a hard fixation of blanks, the possibility of fixation of the carriage to facilitate loading sheets, additional start and stop buttons of the machine.

Particular attention must be paid to the ease of sliding the slide. The easier the sliding table is to move, the less effort and therefore the more efficient the machine operator is to work.

Saw unit of the formatting and cutting machine

Main parameter to be paid attention to is the engine power of the main saw. For cutting standard types of chipboard a 4 kW engine is enough. For batch cutting as well as processing 40 mm kitchen worktops or working with solid wood, 4 kW may not be enough.

The scoring saw is used to make a clean cut on the underside of the board when formatting laminate. It is a good sign if access to the trimming unit settings is from the outside, easily accessible for the machine operator. A 1 kW motor is sufficient for the scoring saw.

For furniture making it is important to make cuts at an angle of 0 to 45 degrees. Most panel cutting machines have a saw tilt option for this purpose. Some machine builders offer machines with a blade tilt from.1 to 46 or from.46 to 46 degrees.

It is important to choose diameter of used saws. For basic machining of panel materials 300 mm in diameter is sufficient. For batch cutting you will need a 400 mm diameter saw unit. For high-quality cutting of laminated panel materials it is necessary to have the saw blade height adjustment function. When routing slots it may be necessary for the saw to retract completely under the table.

Rulers and stops

In order to accurately position the workpiece to be cut on the work table of the formatting and cutting machine use rulers and stops. The quality of their operation determines the size accuracy of the workpieces at the output.

Two kinds of stops are used on standard formatting machines: lateral and frontal. The side stop is positioned parallel to the saw blade on the right hand side. It must slide freely on its bearings over the table and can be tilted as needed to cut larger workpieces.

The front stop is perpendicular to the guide rail on the sliding table and has a ruler and several tilting stops. It must pivot in relation to the axis of the carriage to make cuts at an angle. Stops should be made of aluminum alloy to make the work of the machine operator easier.

Ruler scales should preferably be engraved and clearly visible from different viewing angles. Some manufacturers offer as an additional option stops with digital indication.

Control panel of the formatting and nesting machine

Depending on a saturation of a machine by these or those options control panel can consist of both several buttons to enable and disable the main units, and electronic control system with display of all indicators. On modern digitally controlled automated machines the setting for working with different materials is made with a few button presses. Rotation speed, height and angle of the main saw blade are set and the trimmer unit is adjusted. Cutting cards can be displayed on the screen and the order of execution can be checked.

In addition, the digital control of the parameters of the main units of the format-cutting machine can greatly simplify the procedure of their setting and reduce the time for tool changes.

Cutting equipment

The machines are designed for longitudinal and cross cutting of timber, cutting and format trimming of boards, including removal of overlaps after facing, as well as for cutting of full-size boards into pieces of the required size. There are different types of nesting equipment. A distinction is made between horizontal and vertical formatting and cutting machines, double-sided machines, CNC and non-CNC cutting centers.

The choice of one or another equipment depends on the tasks that are solved in the production of this equipment. In this article we will consider types of cutting equipment and principles of work of each type.

Horizontal panel saws

Purpose: Board nesting machines are widely used in furniture industry. Produces longitudinal, cross and angle sawing of sawn wood, chipboard, fibreboard, plywood and any panel material faced with veneer, laminate, plastic. Circular sawing machines have a main saw and a coping saw with concurrent rotation direction, which ensures high quality of cut.

Modern panel sawing machines have two saws. the main saw and the undercut saw. Due to the fact that the undercutting saw rotation direction is parallel to the material travel direction and the kerf width is a few tenths of millimeter wider than the main saw which rotates counterclockwise, a clean and chip-free cut is formed. A modern machine consists of a stationary frame with fixed saws and a movable carriage, on which the material to be cut is placed and moved in the cutting direction. Machines are equipped with all sorts of auxiliary devices (mechanical, pneumatic, hydraulic. clamping units). Various electronic devices for size adjustment, etc.д.) for easy operation and increased possibilities of the equipment. The sizing machines are produced in many European and Asian countries with different characteristics and reliability.

You can see at the following link how the panel saw works.

Cnc Circular Nesting Centers

Function: The CNC panel cutting center is designed for automated cutting of the faced and unfaced package of chipboards, hardboard, wood-fiber boards and other plate materials by means of a programmed cutting map. All nesting map optimisations can be carried out. As a rule the CNC panel sawing centers are used in high volume production of cabinet furniture.

CNC panel cutting centers consist of a worktable with panel material on it. The table is a table equipped with a ball bearing surface (the material to be sawn rests on numerous balls under air pressure), due to which the massive package can easily move on the table surface without damaging the material itself. Material on the panel is positioned on the stops, pressed by the beam to the supporting surface (the beam reliably prevents the material from moving across the table), then the material package is sawed by the moving saw carriage. The saw carriage is an assembly of a scoring saw and a main saw for clean cutting of the material. The material is moved and positioned automatically using stops and pneumatic clamps controlled by the nesting optimization program. The panel loading is done manually on the front-loading centers or automatically on the rear-loading centers. The nesting process is controlled by a panel cutting optimization program to increase the effective panel yield and minimize the percentage of panel losses.

The panel saws are produced in many European and Asian countries with different performances and capacities.

Circular saws vertical

purpose: cutting of panel material. These machines are used in cabinet making, woodworking and other industries. The most common horizontal layout of the main functional mechanisms of a circular slicing machine is as follows. This particular arrangement is responsible for a number of disadvantages. After each cut of plate material the sliding carriage must return without load, which results in significant loss of productivity. Machines with horizontal layout are very large, so they take up a lot of floor space. Either longitudinal or cross-cutting slab (plate) material can be produced with a single machine. е. No possibility to make longitudinal and cross cuts alternately.

Working principle: These disadvantages are eliminated in the slicing machines with vertical component layout. To cut a plate on the panel forming machine with vertical layout of units, you need to place this plate in a fixed vertical position, and then the saw slide will move in perpendicular axes along the sawn plate. From the description of the advantages of the vertical arrangement of the machine units, it is immediately clear that this way the machine does not take up much space, and thus there is a saving of working space. But this is not the only advantage of such machines. When sawing on this type of machine the material to be sawn, as it has been already said, is placed motionless and does not move, sawing assembly moves directly that guarantees exact geometry of cut. A few more words about high productivity and reliability of the machines. Plus they have the advantage of large cutting lengths, and all that in the basic version (up to 4100 mm). This equipment is very rarely used because of its difficulty of setting and lack of versatility (cutting only board materials at right angles)

Double-sided sizing and cutting machines

Purpose: Rectangular formatting (trimming) of glued laminated woodblock, plywood, veneered panels (chipboard, hardboard, fiberboard). Used for the production of joinery, furniture, plywood and board materials. The machine can be integrated into a trimmer flow line.

The workpiece is placed on high-precision polished metal beams. Manual feed into the working area or optional automatic motorized feed. Cutting is performed by means of two sawing units one of which (left) is fixed, and the other, moving along two rigid steel guides, adjusted to the required size. With manual feed the distance between the saws is read off on a scale, with mechanical feed, by a mechanical counter. The saw units are pneumatically tilted back 1 mm at the end of the cut to prevent splintering when returning the cut.

Do it yourself or order it in?

High-quality chips are difficult to saw by hand because of the large size of the sheets. The dimensions of a standard board are 2440×1200, and this is not the limit. If, however, you work with particleboard or fibreboard quite frequently, it makes sense to buy expensive tools and work at your own pleasure. If you only have a few sheets to cut, there are two possible ways around it:

It’s up to you to decide, but we’ll look at each of these options.

Operating principle

The principle of a particleboard machine is not complicated:

• The plate to be sawn rests against the left stop of the work table.
• Marking of the cutting line.
• Engine starts.
• After setting the working speed, the table moves on rails to the disk and make a cut on the planned line.

The basic settings and adjustments for the unit are as follows:

In furniture factories additional equipment is used beside the sawing machine for finishing and auxiliary operations. This is a router for edge trimming, a laminating machine, and a drilling machine

Ensuring the safety of work on woodworking machines

Mechanical cutting of wood produces not only chips, but also wood dust.

This imposes higher requirements with regard to fire and explosion protection regulations for repair work. The level and quality of the work performed, as well as the replaced parts of the power equipment and other elements of electrical circuits, must comply with the specified protection class and fire and explosion safety requirements.

It should also be remembered that woodworking machines and equipment are source of increased danger to the staff operating this equipment.

Engineers will help to restore fencing constructions, return functioning of protective automatics and mechanisms, which prevent industrial injuries, will teach how to avoid accidents while working with this type of equipment.

The company carries out repair of woodworking machines and equipment in St. Petersburg and Leningrad region.

We are ready to realize a complex of repair-restoration works, both in own workshops and on the territory of the customer. Responsible approach and high quality of the work performed is guaranteed!

With flexible saws

Only band saws are used for woodworking. Also there are rope and chain (bar), but they are used for granite, marble and other rocks. The main sawing options for band saws are cross, lengthwise, and curved.

Similar woodworking tools are divided into floor and table. The floor spools consist of a one-piece construction and are used in industry thanks to their high output and power. Tabletop designs are convenient for manual domestic use. Can be installed on a table or workbench, some models are equipped with a special stand.
