Types of milling plants: what are the types and their purpose
During milling metal processing, it is important what type of milling cutter the master chose. In the article we will talk about numerous varieties and features of their application. this will be needed both for a beginner and to repeat to a professional.
This tool is universally used on modern equipment in order to create any form on the harvesting of a cut. This is a fairly optimal device that allows you to make holes, grooves, and also remove the excess steel layer.
The tool unit is created from a durable instrumental alloy in compliance with maximum accuracy. To fulfill the parameters that are declared in the TU, the processing of a end tool with a large set of teeth is used. cutting inserts regulate the parameters up to 1 MK.
Structurally, the cutter has several working sharp faces. Inserts are often made of diamond, ceramics and card wire for strength.
Each tooth has, in turn, the front and posterior surface, cutting edge.
The principle of operation is that the tool rotates rapidly. At the same time, the workpiece moves. When contacted mechanically, under the influence of pressure, the upper layer of steel is cut off.
Metal milling types
Usually, with versatile activities and numerous tasks, the milling machine has a full set, and he himself knows very well how they work. But beginners need to make a small review.
They are a disk with teeth. In this case, the cutting edges are either on one side, or on both. depending on the purpose. During the stages of metal processing (from black to finish), the size of the zazubin may change. Cooling tool is used under difficult cutting conditions, when it is very difficult to remove the chips from the work area. When this type of milling is used:
Accordingly, among the discs you can find cut.out, rubble and other subspecies. We will talk about some of them that have constructive differences.
The teeth of such discs are equipped with two cutting edges. classic on the end part, as well as on a straight surface. Such a modification is more expensive and more productive.
Even more dangerous teeth. now they are equipped with three blades, that is, from each side. along the edges, from the ends and from above.
There is only one edge located on the working surface. The tool is suitable for not very deep and accurate steel sample. It can be with a different number of teeth and the depth of the recesses. One common name cutter of this type is “Lastochkin tail”. Why? Because the cutting area has the shape of a truncated cone, like feathers of a swallow.
From the name it is already clear that such a tool works with its lateral part. It is the ends of the cylinder (of different widths) that are endowed with blades that process the plane of the metal workpiece. The part is installed, respectively, perpendicular to the steel part.
Very often they come with removable plates, which saves the cost of the milling machine. This is possible, thanks to the general massiveness of the design. The advantages include:
- Easy to work with flat elements, sheets and stepped surfaces.
- High speed of metal processing.
- The smoothness of the process.
Cylindrical mills for metal. what is it
Form. cylinder. A rather massive tool that is convenient to do planes. This is the main type of machine equipment of both classical mechanical and CNC. On the site https: // Stanokcnc.ru/ large selection of milling equipment with a numerical control panel. Modern modification allows you to increase the speed and performance of one workplace, as well as reduce the risk of errors due to the human factor.
Cylindrical tools can be with different forms of teeth.
Less popular and universal, even rarely encountered. It is good and convenient, but with a very narrow work profile: the equipment should be located in parallel headlines, and the metal processing section should have easy access, even surface. In general, such ideal conditions are rare. these are only narrow planes.
The most multifunctional, universal and, accordingly, in demand. The cut lines do not go straight, but along the twisted spiral. The given angle of inclination can be different. Depending on the selected faces, you can actually carry out any sample. on various details. Peculiarities:
- High effort when working.
- The possibility of using double tools, when the faces are in opposite directions. this reduces the force that affects the edges.
A separate type of milling cutter is “corn”, which is used in the processing of ledges and the creation of grooves and their grinding. They look interesting.
This is a truncated cone that has sharp outer edges and ends of the teeth. The main purpose of use is metalworking of angles and uneven surfaces, removal of rectangular chamfers. They also with their help make chip grooves and many additional operations. The cutting edges are made with a slope, which allows you to achieve any work angle. Let’s see what subspecies are.
The second name is all.metal. Their essence is that the whole structure is made of one durable material. Additional improvement. the presence of ring grooves that allow you to freely remove the formed chips.
Snaped cutting plates (crowns)
Everything is simple here, the tips are selected, and then soldered to the base. The teeth themselves are made of solid alloys, their modifications are many, the coronal is common.
For preliminary processing
These are cutters that do not differ in high accuracy, but are designed specifically for a rough cut of a large volume of metal at once.
For the finish stage
They have smaller, shallow teeth of hard alloy with the addition of other strong abrasive substances. They should not be confused with grinding. The task is to achieve maximum cleanliness during metalworking.
With a cylindrical tail
The tail is not working, it does not interact with the workpiece, but serves for reliable fastening in the fasteners of the base. When the tail is created in the form of a cylinder, that is, a barrel, the possibilities are quite limited. movement can be carried out only at one angle, so only straight surfaces are processed.
Why are cutting mills with a tail of a conical look
Such a modification has much greater freedom of action only due to adaptability to inclination. Due to this, they are more common, especially when equipping with CNC machines. Modern high.tech equipment can be ordered on the website https: // Stanokcnc.ru/.
Principles of Classification of Frasing Metal
Various types of milling machines are due to the design and purpose of the tool, as well as the method of feeding cutters, among which you can distinguish a screw, rotational and straightforward. The working edges of the cutting tool, each of which, in fact, is a cutter, are made of especially hard alloys of steel or from materials such as ceramics, diamond, card wire and others.
The variety of milling plants makes it possible to select the material in the most complex areas, as a result of which the required form is given the workpiece and it turns into a specific detail.
Classification of milling plants is made according to the following parameters:
- the location of the teeth (incisors);
- design (team, solid);
- the design of the teeth;
- direction of teeth;
- method of fastening cutting elements;
- The material of the cutting elements.
Metal milling types
Any beginner master who has a need to process metal has to look for information about what mills are there. We describe the most common types of milling plants for its intended purpose.
Disk cutters are used for the following types of work:
The cutting elements of such tools can be located on both one and two sides. Depending on the type of processing (on preliminary to finish), the size of the cutter and its teeth change. Carrodic disk mills operate in the most difficult conditions with high vibration and the inability to effectively remove chips from the field of cutting.
From the varieties of such tools, one can distinguish:
The names of these instruments are determined by their purpose: for example, cutting cutters are needed for segments of metal blanks on milling machines, and with the help of rubble, grooves and slots are cut.
Such cutters work with flat and stepped surfaces of metal parts. From the name itself it is clear that the end part of the tool is a working one, respectively, the axis of its rotation is perpendicular to the processed plane of the part. Most often, such mills are quite massive, so it is convenient to use interchangeable plates in them. A large number of teeth on the site of contact with a part of the metal allows you to achieve a high speed of processing and smooth operation of the tool.
Trees of this type can be both straight and screw teeth. The first to process narrow planes, and the latter work smoothly and therefore received universal use.
Axial efforts arising from certain modes of milling plants with screw teeth are very high. In these cases, double tools are used, the teeth of which are located with a different direction of inclination. Thanks to this decision, the axial efforts arising in the cutting process are balanced.
This type also includes rashpilly cutters of the “corn“, with their help process ledges and cut through the grooves.
Cylindrical cutter type “corn” in work
The edge of such a cutter on metal used to process inclined surfaces, as well as corner grooves, has a conical surface. There are both single.iron and two.horn types of instruments that differ in the location of the cutting edge (in two.horned models they are located on two adjacent conical surfaces, and in single.iron ones on one conical surface). With the help of such mills, you can perform chip grooves in instruments of various kinds.
To form grooves with mowed side surfaces, single.iron tools for metal “Lastochkin tail” and an inverted “swallow tail” are used.
Most often, end (or finger) mills for metal are used to create grooves, contour ledges and recesses, processing mutually perpendicular planes.
End cutters are divided into several varieties according to the following signs:
- monolithic or soldered cutting elements;
- with conical or cylindrical shank;
- for the final processing of metal (small teeth) or for rough (large teeth).
The end carbide cutters are used to work with poorly processed metals. steel, cast iron, etc. Among the end mills, spherical (ball) necessary for the processing of spherical recesses, radius, serve to select grooves of various shapes, fungal-carbide cutters for T-shaped grooves on harvesters of cast iron, steel, non-ferrous metals. The ends also include engravers or cutters for engraving, which are used to process precious metals, copper, brass and other materials.
From the name it becomes clear that this type of cutting tool is designed to process shaped surfaces. Such cutters are actively used for processing metal parts with a significant ratio of the length of the workpiece to its width, since shaped surfaces of parts of small length in large industries are more often made by extending. Shaped mills with a plug angle is most difficult to sharpen.
By the type of teeth, shaped milling tools for metal are divided into two types:
Processing is performed by the method of driving due to a point touch of the workpiece with the tool. Worm mills are divided into a number of subspecies according to the following parameters:
- integral or prefabricated;
- right or left (direction of turns);
- many- or single-rise;
- with unsolved or polished teeth.
Such tools serve to obtain holes, and the ring mills provide a higher cutting speed in comparison with spiral drills by approximately 4 times.
There are cutters for metal not only for CNC machines, but also for a drill. Otherwise they are also called bores. Their design provides a special hairpin for a clamp in a drill cartridge. Bouresis can be found on sale only in the form of sets, since working with metal using a drill requires accuracy and corresponding to a specific task of the shape of the cutter.
For a hand cutter, cutters are also bought with a set. There are bromatic tools with a bearing and without it. The former are used for processing on a manual milling edge of the part, the latter can be used on any section of the workpiece, however, templates are required for more accurate work. On the domestic market, as a rule, there are Chinese cutting tools for a hand cutter, but their quality can be evaluated as a fairly high.
Types of milling plants: which is better
You can’t choose one universal mill for all tasks, even if it is the best. It is important to make a machine to the maximum with an instrument required to solve all the problems that are facing the master.
We continue the topic of milling. For those who missed, the first part about mills here.
It is not so easy to understand the types of milling plants on metal. Some are necessary for sample metal, the latter are useful for processing inclined surfaces, the third are cut through the grooves One thing is clear: any self.respecting milling machine has the most popular types of this tool in the arsenal to realize any order. Based on what form is required to give the details, the master will select the cutter. Let’s go through the main ones.
If you need to create a contour ledge or recess, then the milling machine will need an end type tool. Thanks to it, you can also easily process any planes. Among the end mills are highlighted:
end mills. They are simply necessary to pull out flat or stepping details. The main removal of the metal is carried out by the side of the milling cutter during longitudinal supply, and the processing of the horizontal plane is carried out by the peaks of the cutting elements and is considered additional;
spherical with which it is easy to process a curved surface;
radius, intended for milling grooves with internal and external roundings.
They are also called fungal for the characteristic geometry of the cutting surface. The tool is used for the manufacture in the workpieces of the T-shaped groove or curly protrusions.
If you need to cut off the excess part of the workpiece, cut out the groove or remove the chamfer, then disk mills are suitable for this work! Despite the unusual shape, this cutting tool is often used in metalworking.
Diskeeper’s teeth are equipped with additional working edges at the ends (or one of them). And the size of the tool and its cutting elements depends on the type of processing. on the draft to the finish.
This type of milling cut is under the power of work in the most difficult conditions. with vibration, clamping, poor abduction of metal chips.
This is a variety of disk tools, which differs in the presence of the angle of inclination of the cutting edge relative to the horizontal axis.
Using an angular instrument, the cutter will process any angular recess, an inclined surface and even a “Latochkin tail”.
Shaped mills found their purpose for milling blanks, which have too strong the difference between length and width.
The teeth of shaped mills are found both sharply and plundered.
This tool is slightly abrasion during milling, while it differs in the quality of processing. The only problem is sharpening that you can only use special devices. Therefore, shaped mills are used mainly only in large industries.
Quite specific, and therefore not a very common type of metal.cutting tool. It is used to cut teeth on stars, shafts and other products.
The sample of the metal is carried out due to the point effect on the workpiece.
Based on the technological assignment, the milling holder may come in handy at once several mills. Fortunately, all types and sizes of this tool for metalworking are on sale, which will allow the master to make the machine as equipped.
Metal processing and woodworking are so common procedures that there are practically no production sectors, wherever the machines are used to any extent. Now the best equipment is with CNC. They are the most accurate, fast and energy.efficient. You can buy them on the website https: // Stanokcnc.ru/.
- equipment production;
- manufacturing of pipes and metal rolling of another packaging;
- aerospace plants;
- furniture and interior items;
- fasteners and metizes;
- auto industry and much more.=
Differ in the area of application depending on the purpose, let’s look at the image:
How to properly sharpen the cutter for metal: several ways
The main task is to process a curved surface on both sides, which has a large length. In this case, the cutting tool is an abrasive substance. It should be directed directly along the edge (at the right angle).
How to hide with a machine
Technologically, this process occurs in several stages:
Chaoseum. Smile Again (Official Music Video)
- Fixing the tool in the right position in the mobile part of the bed.
- Bringing the cutting element to the rotating abrasive circle until uniform spelling.
- Trimming the metal layer, up to 50 μm wide.
In this case, the following recommendations are required:
- Each tooth needs a separate drag.
- Movement should come from the beginning of the furrow to the outer edge.
- All cycles must be carried out the same in order to achieve complete uniformity in the cutting edge.
How to hide mills with the help of sharpening circles
This is a special equipment, the nozzle of which is from an abrasive substance and is a closed tape:
The peculiarity of the wiping is the correct choice of material. What abrasives are sold:
- White or classic electrocorundum. It is most often used for ordinary woodcers for wood or metal.
- Elbor. well processes high.speed steel.
- Silicon or diamond carbide (natural, synthetic) perfectly copes with carbide products.
Recommendation: Use cooling lubricants in order to reduce the thermal effect of friction force.
To do this, you need a home.made device or table for a hand cutter.
- Using a special liquid, it is necessary to clean the surface of the tool from soot. To do this, you need to place the cutter in the container and leave it there soak for 3 minutes., then clean with rough bristles.
- Using a diamond bar, turn the edge in front so that longitudinal movement is ensured.
- Wipe the finished equipment with a soft rag to eliminate metal dust.
What is the end mill made of?
Most of the materials of the end mills of the carbide end mills or are made of cobalt steel alloys, usually called high.speed steel. The choice of material will depend on the maximum speed of the spindle of the machine and the hardness of the workpiece / material.
Carular terminal cutter
All-hard-saved end mills do not provide the same cutting productivity, provide high reliability of the process and a long service life of the instrument to ensure the safety of the process of production of parts in industries such as medicine, air-cosmic industry, production of electricity, as well as press forms and stamps.
Extremely high quality and low cost of production, as a result of which the advantages of these end mills are that they serve as a guideline for a special microfernational carbide structure in specialized goning of the edges, optimal grooves and wear.resistant coatings.
This end cutter is significantly more rigid, solid and wear.resistant than others. In carbide end mills are used for high.speed applications and have extremely high heat resistance on some of the hardest materials, for example, non.ferrous metals, cast iron, alloy and plastics.
The end mill HSS
The recently developed AG coating and highly alloyed HSS reach the optimal balance of viscosity and wear resistance, providing high efficiency of processing and grinding. This end mill provides stable operation in severe cutting and is suitable for lateral milling and preliminary finishing grooves. The terminal milling cutter made of high.speed steel is supplied at an affordable price, but does not provide such speed and resistance as carbide end mills.
Why are the end mills used?
End cutters are used to perform holes and shapes during deployment, give shape, profiling, milling, drilling and processing grooves. They look like cutting teeth along the edge of the whole body. In addition, they cut the material into various drawings.
Ending mill for aluminum
Slot machine end mills with two grooves are used in aluminum and wood. These grooves are best suited so that this material remains a little colder, and best for the air to remain a little colder. However, this leaves a rude cut.
Clock cutters with two cutting edges are best suited for processing aluminum and wood, since they produce huge shavings compared to other materials. These end mills with grooves are also compatible with groove drills and are ideal for profiling, cutting grooves, aluminum and wood.
Traditionally, end mills with 2 teeth are an impeccable choice for aluminum processing. But end mills with 3 grooves are also compatible with aluminum. Three grooves are more effective when decorating materials, and with proper stricture, they can also successfully work as a rough fabric.
End mill for stainless steel
For more rigid material, such as steel or other more solid material, end mills with 4 grooves are compatible. 4 grooves. This is not only an ideal end mill for stainless steel, but they can also create a smoother surface on other hard surfaces.
Application of end mills: which and why?
Of all types of equipment with software management, milling and gravity machines have the greatest coverage in terms of operations performed and production industries. This is facilitated by a large range of cutting tools, which can be fixed in a spindle, high processing speed and precision accuracy of commands. Unlike manual, the computer control of the machine minimizes the appearance of any marriage and provides the maximum identity of serial blanks and products.
Assortment of cutting tools for milling equipment with CNC
Milling equipment are used in metal and woodworking, interior design and advertising business, in the manufacture of ritual, souvenir, household goods and many more areas. Depending on the tool cartridge installed in the cangy cartridge, you can drift, engrave, fugue, melt the blanks, remove chamfer, make grooves, curly excavations, conduct black and finishing processing, etc.D.

End mills: what are and for what they use
Straight end mills, which are most often installed on CNC machines
The end mill is most often used in the processing of materials and is the body of rotation with sharply bonded elements on it. The tail of the instrument is clamped in a spindle canovic cartridge, and the other, equipped with cutting edges, acts on the surface of the workpiece. A large selection of forms and raw materials, from which end mills are made, allows you to choose the right tool for almost all types of work for any materials: from cardboard to metal. The main criteria that should be paid to the acquisition of the end milling cutter: the following:
End cutters are divided into two large groups:
-for wood-the angle of sharpening in such mills is greater and is 45-55 ° C, and even compressed metal powder can be the material of manufacture (although, despite the relative softness of raw materials, instrumental steel is still preferable for wood). With such sharpening, the structure of the workpiece material is not damaged, and after finishing milling, even and smooth walls remain.
The main requirements for materials used in the production of end mills are thermal resistance and resistance to wear. In the manufacture of milling tools, the most commonly used instrumental, carbide and high.speed steel. These are materials of increased hardness and strength, which are able to withstand the mechanical and high.temperature load for a long time. In addition, artificial and natural diamonds, minerals and powder mixtures can act as the starting raw materials. However, most of the milling plants is made of high-speed instrumental steel, which is characterized by maximum wear resistance and is 3-5 times higher than carbon;
Milling processing is divided into black and finishing. In the first case, the work is to remove the surface layer of material without high detail. For this, mills with small teeth on the cutting edges are used, which grind the chips well. For finishing processing, an acute tool of the desired shape and diameter is used, which brings the relief of the workpiece to the final result;
End mill for black processing with characteristic grooves on the edges
The number of cutting surfaces
The main functional element of any end mill is an acute edge, which cuts out of the material all excesses. Each surface makes one cut in one revolution, respectively, the more edges, the higher and more precisely the processing speed. There can be more than five such surfaces, but most often two-, three- and four-member mills are used. In the majority of milling, the cutting elements are spirally placed, and the distance between them and the angle of sharpening of each edge depends on the size of the tool and its purpose;
The classic terminal mill has a drilling shape with centrround teeth, which allows you to deepen the tool into the material without preliminary preparation. This is the most common type of tool, in total there are many options for milling, for example, spherical, for 3D engraving, angular, with a conical body, groove, profile and others;
A very important parameter that facilitates work with materials prone to increased chip formation (aluminum, plastics, wood, etc.D.). The presence of special grooves between the notches of cutters that take the chips up reduces the likelihood of overheating of the tool, prevents the cutting edge of the cutting edge and facilitates the control of the processing process. There are also cutters with the removal of chips down, but they are less convenient, since in this case the waste clogs finished holes, grooves and other recesses.
Features of choosing the cutting mode of cutters during milling
It is worth noting that there are several stages of metalworking:
- Pendant. very rough removal of the upper layer, often consists in eliminating obvious defects, as well as that rust is removed.
- Draft. primary processing, when you need to eliminate the surface and remove the chips. At the same time, the class of accuracy and roughness is quite low. The allowance is left enough. up to 7 mm.
- Polistova. At this stage, cleaning and preparing for the final stages is carried out. The peculiarity is that a thinner tool is selected, the chips are thinner, and the accuracy increases to 4-6 classes.
- Finishing. often the last level of processing, optimal roughness is achieved. The dimensions are adjusted very accurately.
- Subtle (finish). ultra.precise milling at high speeds. Minimum metal dust is removed.
- Grinding. cutting with abrasive particles are used.
Depending on the stage, the calculation of cutting modes during milling is made. it can be made online or use the formulas and tables. Accordingly, the type of drill is selected.
The choice of tools
Different mills are used as equipment of milling machines. These are cutting devices made of instrumental steel of high strength. There are many signs according to which the classification takes place:
- based on the material of their cutting elements;
- by the location of the cutting parts of the teeth;
- by type of sharpening of teeth;
- in the direction of the teeth (screw, inclined, etc.D.);
- according to the design of the product (component, whole, prefabricated);
- by type of attachment of cutting elements.
- According to the intended purpose. the name of the cutter is consonant with the task of the milling. Consider some of the varieties.
For flat surfaces
Basically, when processing the planes, cylindrical and end cutters are used, as well as disk. for sawing. If the tool is in the form of a cylinder, then it can be several types. with whole or interchangeable cutting edges. Large monolithic are usually used in the first stages of metalworking, in black work, while small and collapsible. for finishing.
The end cutter is more suitable for extended blanks. Then her teeth can be on the sides. from the end. If this is a large folding tool, then it is used, respectively, for wide surfaces.
The use of carbide cutters is mandatory if you have the pleasure of working with poorly processed refrigerating materials. But it is worth considering that you will need a protective width and length of the cutting edge, then a good shavings will leave.
For art milling
Decorative metal inserts are particularly popular in the interior of housing or office premises, but such elements can also be added when designing cars, when engraving any products, for example, wristwatch, and in other cases.
Mostly for these purposes, end or disk nozzles are used. A more modern, productive and accurate way is the use of CNS laser machines, they quickly and perfectly correctly repeat the specified contours, apply recesses and patterns. They can be purchased at the HTTPS: // Stanokcnc online store.ru/.
Cutting modes for milling with end or groove cutters are ideal for creating a groove, grooves. They can have from 1 to 4 or more visits, various widths and length of the teeth, interchangeable nozzles or monolithic. They are made from any suitable material. A wide variety allows you to choose a tool depending on the purpose. By the way, they are suitable for manual control of the machine and for the numerical.
Discs do a great job of many tasks. ranging from rough and fast sawing, ending with a thin, almost jewelry work on a decorative metal element.
For processing edges
Unfortunately, not every cut has ideal characteristics: smooth, without hooks and burrs, with the right class of roughness and accuracy. The same applies to all corners. it is difficult to get to them, at least not as easy as to a straight surface. The following nozzles are used for this:
- Silent and slotting can be applicable to separating one part of the material from the main array.
- With the help of corner, you can process corners and edge. In this case, there are two varieties of this tool. with one and two cutting edges.
- The shaped is used for parts with a non.standard and complex bend. for round, concave surfaces. Very often used to cut some fixing tools.
Typically, all of the presented species have options with monolithic manufacture of hard.sailed raw materials, as well as folding. with removable nozzles. The first option is more suitable for black metalworking, and the second for finishing and thin.
Cuts with straight blades
The best choice for working in grooves. Thanks to this feature, CNC cutters with straight knives received the second name. grooves. The tool copes with the processing of multi.layer materials perfectly. There are a number of specialized mills for working on plastic, wood and other materials. The specialization of the tool is determined by the features of sharpening.
Compression reference mills with the complex geometry of the cutting edges are included in compression. The upper knife of the instrument is directed down, the lower, respectively. Up. This location of the blades prevents the formation of chips and other defects on the surface of the processed material. The scope of compression mills for CNC stages is the processing of laminate, soft wood and other materials prone to cheapening and the formation of a pile. It is important that compression mills are characterized by a long period of resistance. You can work with a compression milling mill in one or more passes. It is important that the lower knife is shorter than the thickness of the material removed. Neglect of this requirement inevitably affects the quality of cutting. In this case, the tool works as a regular milling cutter upward, and the upper edge of the material is damaged by the lower knife.
Compression cutters (with counter.directed knives) are used to process a laminated tree without forming chips, both on the upper and on the lower edge of the cut. These cutters perfectly process medium density wood, plywood and multi-layer slabs, materials with one- and bilateral laminate, various plastics, wood-fiber plate, wood-steering plate.
What tool to prefer
Today to purchase metal cutters used to equip an electric drill is not of particular problems. A large selection is offered by specialized offline and online stores. The price of the tool depends on both its type and constructive performance, and on the brand.
The mills in the sets are cheaper in terms of each unit, but a professional tool is more often sold by a piece and is much more expensive
When choosing a metal cutter for its use complete with a drill, it is better to give preference to the products of trusted manufacturers, which will last you longer and ensure the high efficiency of the processing. It is worth giving preference to tools from the following manufacturers:
- “The globe”;
How to choose a metal cutter correctly
To select a metal cutter to equip an electric drill, you should pay attention to parameters such as:
- location and design of the cutting edges;
- type of shank with which the tool is fixed in the drill cartridge;
- Material of the manufacture of the case and cutting part;
- Sharpening quality.
It should be borne in mind that the electric drill on which such a mill will be installed refers to the equipment of the manual type, so you should not choose a tool for semi.automatic and automatic machines.
Forms of carbide milling plants for a drill for a drill
In the event that you need to purchase a cutting type cutter for a drill, you should also pay attention to how well the cutting part is mounted. Cutting plates, which are mainly attached by soldering by the instrument, otherwise they can fly out in the process of processing.
Sharpet quality is an important parameter that directly affects the performance and quality of processing. Despite the fact that many manufacturers are trying to sharpen their mills using unique technology, instruments should be preferred, the sharpening of which is carried out according to one of the standard schemes.
Each milling cutter is intended for processing surfaces of a certain configuration
Both its durability and quality and processing productivity depend on the material from which the milling machine is made. For the performance of one.time milling work by a drill, the quality of which is not made of high requirements, you can choose a whole tool made of steel of one brand. If the cutter often has to be used often, while you need to get high.quality products, it is better to give preference to more expensive tools, the cutting part of which is made of carbide plates.
Homemade cuts-spaces made of tall hot nuts and welded balls from bearings
Many home craftsmen who want to save on milling cutters for a drill make them from improvised means. Of course, it is difficult to achieve a qualitative result with the help of such a home.made tool, but it is quite capable of dealing with elementary tasks. The following improvised means are suitable for its manufacture:
