The Better To Grind Wood Angle Grinder • CIMFLOK.COM

The intricacies of flawless hand sanding. How to choose sandpaper for woodworking?

There are quite a few characteristics by which sandpaper is classified. But the main and most significant parameter to be guided by when choosing a skin is the size of its abrasive grains. the so-called. Grain index. For specific tasks when working with wood, a certain type of grain is chosen.

TABLE: CHOICE OF ABRASIVE FOR WORKING WITH WOOD

Practice shows that a master needs a set of five types of abrasive to perform basic tasks:

P150; P180; P240 (wood treatment before finishing)
P280; P400 (intercoat and final sanding of finishing coats).

You can read all about the intricacies of choosing sandpaper in this article.

In sanding pads and their creation by hand

Sanding pads (grinding). an irreplaceable assistant in the arsenal of the joiner. These simple devices ensure uniform contact of the sanding paper with the work surface, increasing the speed and quality of work performed. Using such pads, you can significantly improve the quality of grinding, extend the life of the abrasive, and avoid irreparable defects in the form of grooves and rounded ends.

To acquire such a grinding tool, there is a need to spend extra money. It will not be difficult to make an ego with your own hands from dense foam or wooden scraps. Check out some simple sanding pad designs in our gallery.

Dry or wet sanding?

For intermediate sanding of finishing coatings. stains, varnishes, hydro, etc. Traditionally two techniques are used. dry or wet.

Dry sanding increases the efficiency of the abrasive and allows better control of the work process, which is especially important in the intermediate sanding stages of delicate coatings. The disadvantage of this technique is the rapid clogging of the skin. Partly this problem is compensated by sandpaper with an anti-clogging stearate coating.

When wet sanding wood products, use mineral oil, white spirit or ordinary soapy water as a moisturizer. Abrasive with this technology clogs up much more slowly and, accordingly, lasts longer. But the mess from foam and chips makes the sanding process much more difficult. It becomes necessary to constantly wipe the surface and carefully monitor the result of grinding.

What are the benefits of hand grinding?

Manual grinding of wood, although it requires a lot of labor, in return provides a number of fundamental advantages: less aggressive processing, better control over the process and high quality surface treatment in hard-to-reach places. in corners, on smooth bends and other relief of any complexity.

Manual technique It is indispensable for interlayer sanding of finishing coatings, since it provides the most delicate work and eliminates the risk of rubbing the applied finish. When using the same abrasive, hand sanding guarantees a better surface than sanding with a sander, angle grinder or drill.

How to cut wood correctly?

Grinding technique. The wood is sanded with vigorous movements along the grain or at a slight angle, but without excessive pressure on the block. Movement should be as light as possible, on the second or third passes with a fine-grained skin with practically no pressure.

Surface preparation for finishing. Prepare the wood for applying a finishing coat (varnish, oil, stain, hydro, etc.), start working with abrasive P120 or P150 (depending on the nature of the irregularities). After that, go to grit P180 and finish the work with abrasive P240.

Intermediate sanding of coatings. When applying the finishing coating layer-by-layer, intermediate sanding of each layer is performed with fine-grained P280 sandpaper. For finishing polishing, use P400 sandpaper. To remove the slightest roughness of the glossy finish, use an abrasive with grit P600.

The exactingness of finishing coatings for grinding. Matt types of coatings not for centuries Demanding on the quality of sanding as glossy. At the same time, the dark stain will expose all the flaws of unfair grinding.

How and how thin sections of wood

When carrying out various types of repairs, at the time of production of furniture or wooden things, it is often necessary to sand the wood. There are quite a few methods that can be used to sand wood. They have their advantages and disadvantages, some foresee the use of a hand tool.

You can sand wood:

By applying the angle grinder you can prove the condition of the wood to the desired condition. The angle grinder has an abrasive material, represented by a circle;
A conventional drill can also be used in order to prove the surface of the tree to the desired state;
A surface grinder can become the main design for sanding wood;
Belt sanders are used to sand wood with an abrasive material;
Sanding can also be performed using hand tools.

Despite the fact that the considered natural material has a rather high hardness of the structure, quite a few grinding methods can be used, in some we will talk in more detail.

Surface Grinding Angle Grinder (Angle Grinder)

Angle grinder (angle grinder) is a multifunctional device that is also used in the situation under consideration. For this, special circles are used. Petal circles are made from sandpaper, which is attached to a flat surface. In this case, the circle can be of different diameters, with a different grain size. When choosing, the following recommendations can be highlighted:

To remove paint, take a coarse-grained circle;
If it is necessary to remove a thin layer of wood, you can take an abrasive, which has an average grain size;
In order to give the wood a special smoothness, you can use a fine-grained abrasive.

However, it should be noted that the removal of the surface will not be carried out along the fibers. At the same time, it is almost impossible to regulate the rotation speed and feed. You can use an angle grinder when there is no need for a high performance.

In order to carry out the grinding of wood, you can use special equipment, which is called a surface grinding machine. The peculiarities of this one included:

Wood is combed back and forth by abrasive material.
Sandpaper moves at high speed, which allows you to achieve good results when working.
Unlike other methods, in this case the grinder carries out processing along the grain, which determines the high quality of the product.

The design is quite simple, it allows you to achieve good quality. But when changing large surfaces, the grinder has little efficiency. Certain models have a rather large surface to which the skin is attached, but it is rather difficult to provide the necessary force in this case.

Belt sander

Belt sander The most productive tool, which can be used for wood processing with high productivity. The jetting technique also has a high productivity.

Dewalt Belt Sander

The work of the structure is carried out using a circular sanding belt, which can have varying degrees of grain size. The design carries out the removal of material along the fibers. However, you should forget that you cannot grind the corners with this design. The tape can be used for a large amount of work: floor, walls, furniture, and so on.

Despite the great automation of work, it is possible to provide mechanical impact by manual method. This is due to the fact that the removal of fibers can be carried out in the desired direction. It is also possible to carry out corner processing. However, in order to achieve the desired result, you need to have certain skills. The work is very difficult and time consuming. Therefore, hand tools are very popular only in certain cases.

How to cut wood correctly

When the part is ready, its surface should be carefully sanded.

In solid wood parts, it is customary to smooth out cuts or remove traces of glue, sand where the chips have broken off, or clean the protruding wood fibers with the finest sandpaper before the wood is stained or varnished. Even plywood or veneer veneers, which have an almost smooth, flawless surface, can only be varnished without preliminary sanding as a last resort.

Solid wood panels and parts can have almost imperceptible irregularities, which will become clearly visible after applying varnish, stain or a second protective agent.

It is clear that sanding should not lead to new scratches and furrows. You can avoid this danger by using the correct sandpaper and a stone for your product.

Cycling

When planing solid wood blanks, more or less noticeable grooves remain after the plane. The best way to eliminate them is to cycle.

Many DIYers prefer to process surfaces in just one cycle and completely abandon sandpaper. A well sharpened cycle can clean planed surfaces and give them an almost flawless look.

The cycle is a metal rectangle with a cutting edge sharpened at a right angle, which is carried over the surface. The cutting edge is dull and needs to be sharpened from time to time. First, a chamfer (the beveled side of the cutting part) is ground on a sharpening bar or wheel, then the cycle is turned over, placed flat on the bar and in this position is guided over the stone in straight or circular movements, capturing the cutting edge of the edge.

When working, the cycle is taken with two hands so that the thumbs are in the middle of the face facing you. Always set the cycle at an angle and guide it in the direction of the wood fibers. Use the scrubber only on solid wood, plywood or veneer. Chipboards quickly dull the cycles and leave jagged edges. It is better to use sandpaper for processing putty surfaces.

Cycle clean up irregularities left by the plane or protruding wood fibers.

Moisturizing wood and applying a primer

Whether you will do a cleaning cycle or in some other way. in any case, before thinning the surface of parts made of solid wood or faced with plywood or veneer, it must be moistened.

For this, it is better to use warm water (you can even hot water if the part is made of solid wood). Then you need to wait until the parts are completely dry. Small dents will disappear when exposed to water.

But the cut wood fibers, pressed against the surface of the parts in moisture, swell and, having dried a little, stand upright. Therefore, a surface that seemed perfectly flat before moistening often becomes rough, fleecy.

After sanding, the surface becomes smooth again.

Fast sanding primer

The surface of a part made of wood, regardless of whether it retains its natural appearance or is covered with wood stain or varnish, is primed.

The primer closes all the pores, as if it seals them.

As a result, the hygroscopicity of wood decreases, and the paint lays down better and more evenly than on an unprimed surface.

Make sure the room you are working in is dry, dust-free and NOT too cool. This will create the ideal working environment. Applies the primer more conveniently with a soft flat brush.

The primer dries up in about half an hour. But wait a minimum of time before sanding the primed surface with the finest sandpaper (no. 240). Work only in the direction of the grain of the wood, change the skin more often and knock out the fine dust that forms during sanding.

The surface, which seemed to be perfectly smooth, becomes rough, fluffy after moistening.

On the prepared surface, gently apply the diluted primer with a flat brush.

Sanding flat surfaces

When sanding flat surfaces, it is important to use sandpaper correctly: too coarse sandpaper will scratch the wood, sandpaper without a boss treats the surface unevenly. The pins provide an even fit of the skin to the tree of a relatively large area. Usually use a cork lug. But a small wooden block with even smooth edges is quite suitable. You can also use special holder pads made of hard rubber or plastic: they consist of two parts. upper and lower, between which sandpaper is laid.

Coarse first, then fine

To clean rough cuts with a saw, use a sandpaper with a coarse-grained abrasive coating (grit 100).

Sliced surfaces are sanded with 120 grit sandpaper. For fine, final sanding, 180 or 240 grit sandpaper is used. The wood is sanded all the time in the direction of grain growth and without undue effort. Experienced craftsmen avoid sanding the surfaces for a long time, while their movements are very light, almost without pressure. As a result, the tiny ends of the fibers are only pressed against the surface but not cut off.

A special grinding device. the so-called “sand plates” of various sizes and grain sizes. Each is a steel plate with tiny “pins” protruding on the surface with sharp edges.

Belt sander

Belt sander The most productive tool, which can be used for wood processing with high productivity. The jetting technique also has a high productivity.

Better Thin Section Wood Angle Grinder

Than skinning a tree

Before deciding how to sand a wooden surface, first we will analyze the better the wood polished.

There are two ways to skin wood, manual and mechanical. The manual method involves the use of “sandpaper” skins of different grain size and hands in calluses. The second method is mechanical, and special power tools and machine tools are used here. In this article, we will not touch on the topic of sanding wood on machines, some other time, but only with a tool and a manual method.

The better the cut wood

The better is the cut of wood, either manually or mechanically. Above we considered both options, and knowing how to use a power tool is more convenient and faster. But of course there are also such goals for wood processing, where well, you simply cannot reach, or only a little polishing or deburring is required. Let me tell you my version, the better the thin sections of the tree.

I love making furniture with my own hands, and for this I use wood, mainly pine or spruce. For work, I use planed bars and spliced furniture boards. This material does NOT need rough sanding, so I start with 80 grit using a belt sander.

To properly skin wood, you should perform all actions on the wood fibers. If you do the opposite, then you will have stripes against the fibers, and will not look very nice, so you should always sand only along the fibers, at least using a belt sander.

Next, for a fine finish, I use a vibrating machine with 120-220 grit paper, depending on the type and quality of the wood. After such processing, the wood becomes perfectly smooth, but this is NOT the end.

Next, I usually use varnish on my furniture and a primer is needed accordingly. I usually use an oil-based or water-based varnish. Depending on the type of varnish, I make a primer, and after drying, sand it again.

This is done in order to remove the pile, which rises after the primer layer has been laid. The wood is now completely smooth and ready to be varnished or painted.

This is where I will finish this article, I think it was useful to read, maybe we learned something new. I would be glad if you could tell us your version of how to sand a wooden surface.

Drill

The use of a drill for grinding is possible with attachments made of different materials. When working, the tool must be located at a certain angle. Otherwise, burrs and scratches cannot be avoided.

Working with a drill, you can use the manual method of grinding, which makes it possible to process wood in hard-to-reach places. The possibility of using a fixed way of working is also NOT excluded. This guarantees a high quality of grinding, but the mobility of the tool is limited.

Better thin sections of wood: tips for beginners

Several methods are used when working with a tree. Among them I would like to highlight grinding. Thanks to sanding, the surface of the wood becomes even.

Belt sander

One of the most effective devices for processing wood is considered to be a belt sander. The design of the equipment is equipped with a sanding belt with different grain sizes.

The work is carried out on the location of the wood fibers. It is worth noting that the angle grinder is not suitable for grinding the corners of the workpiece. The equipment is effectively used when processing floors, walls or large furniture.

Angle Grinder

The angle grinder is a multifunctional tool. The design of the tool is equipped with wheels of different diameters with an abrasive surface.

When choosing a wheel, it is recommended to take into account the criteria on which the processing quality depends. For example, for what purpose is the processing carried out:

Removal of a layer of paint. a circle with a coarse grain is suitable;
Removal of the top layer of small thickness. it is recommended to use an abrasive wheel with medium grain size;
Making the wood smooth. a fine-grained circle is useful.

Orbital sander

The design of the orbital sander is equipped with a round sole, on which an abrasive hole or paper of different grain sizes is attached.

Vibration sander

This type of equipment is used to polish it. It is also possible to achieve high results with a vibration sander when removing the paint layer.

The working process is carried out using sheets or circles with an abrasive surface. Clips or Velcro can be used to attach them to the sole.

Pros and cons of wood sanding tools

Wood processing is performed using a variety of abrasive devices. When working with them, traces remain. Each of them has its own characteristics. This must be taken into account when choosing a grinding attachment. Among the most popular grinding devices, I would like to highlight the following:

Wood sanding rules

It is possible to achieve high results of sanding a wooden surface, provided that certain rules are observed. Among the most significant are the following:

Before starting work, the surface must be well moistened with warm water.
If there are large irregularities or depressions on the working surface, they must be leveled with a primer. Sanding can only be started after the primer is completely dry.
It is recommended at the first stage of work to use an abrasive of medium or large grain size, and then fine. This allows you to achieve a smooth working surface.

The correct choice of tools and adherence to the rules of work allows you to achieve high results in wood processing.

Electric tools and attachments for it

Voluminous and complex work, such as sanding wooden houses, finishing floor leveling or processing furniture and decorative items, is difficult to do with your own hands. Therefore, here the life of the craftsmen is facilitated by special attachments and devices.

Before moving on directly to the electric tool, let’s say a few words about professional attachments. The simplest and most common attachment is a flap brush for grinding wood, in professional language it is called a flap grinding wheel (KSHL-D (M) 50).

The sizes of this attachment may be different, but the principle of operation is the same for all models. On a plastic circle or drum, emery petals with different grain sizes are fixed along the perimeter from the outside. Clamping such a brush into a household electric drill chuck, you can quickly process large areas, including those with complex relief.

Ribbon brushing.

Removable disc for grinding wood, BASED on a special attachment and most often attached with Velcro. Such a nozzle can be installed on various devices, respectively, and the principle of action on the surface will be different.

After Electric Drill Angle Grinder is the simplest tool for sanding wood. Every good owner has an angle grinder in his arsenal.

To work, you only need to purchase a disk nozzle and a set of removable Velcro discs with different grain sizes. The angle grinder is NOT suitable for fine processing, it is often used for rough processing of log cabins and other similar surfaces.

The draw frame is already much closer to a professional tool, there is an opportunity for both coarse and fine processing. The design itself is simple, the emery is pulled by a closed ring on 2 round rollers.

And when the rollers rotate, the surface is processed. The only problem is the belt unit only works on flat surfaces.

The vibrating machine works by means of small reciprocating movements carried out with a high frequency. The frequency of the average unit is about 20,000 shocks per minute.

A disk in an eccentric machine simultaneously moves both in orbit and around its own axis. For this property, such aggregates are also called orbital. They can also perform a full range of processing.

For the machining of complex surfaces, so-called delta sanders are used. They work according to the same principle as vibratory units, but differ from them in a special shape of the nozzle and dimensions.

This article shows wood sanding work.

Why is it needed

First, let’s define what is generally meant by the concept of wood sanding. In dry language of definitions, grinding is the final or finishing stage of surface treatment before applying paints and varnishes and other similar compositions to it.

Professionals assure that wood surfaces must be polished without fail. Without this operation, the quality of application of primer, varnish or paint will be a strand lower, they will be less absorbed. Since this treatment opens the pores of the material, eliminates small irregularities and raises fine villi.

For professional application of water-dispersed and some other types of varnish, intermediate sanding of wooden products is an indispensable part of the technology. It is performed immediately after opening with the first layer of the coloring composition and is designed to raise the pile and identify minor defects.

But these are all rather technical reasons. In the manufacture of furniture, decorative items and finishing work in construction, the appearance of the surface plays an equally important role. After all, paints and varnishes have the peculiarity of revealing any irregularities and scratches, as a result, it is almost impossible to do without grinding here.
