A grinding machine is a special construction tool designed for abrasive cleaning of the surface of various materials. One of the varieties of such equipment is designed specifically for working with wood. Such grinding machines, in turn, are also divided into several main types.
What type of equipment to choose
Wood grinding machines can be classified according to several criteria. On the market, for example, there are professional and household tools. Also a wood grinder can be:
tape designed for rough surface treatment;
vibration used for delicate grinding;
The latter type of equipment can be used not only for final grinding, but also for polishing wooden surfaces.
Professional or household?
When deciding which grinder to choose for a tree, the first thing to consider is how often it will be used on the farm in the future. Professional equipment of this type has a very large capacity and is designed for continuous use and continuous operation throughout the day. Such tools are made of the highest quality materials and usually have great power. But such machines are often very expensive.
If the tool will be used only from time to time, as necessary, it is worth purchasing, of course, its inexpensive budget household option. In most cases, such machines are designed to be used for no more than 20 hours per month. A household wood tool should work a maximum of 3 hours per day. In this case, when grinding, you need to take small breaks for 15 minutes.
The power of household equipment is also relatively small. The advantages of such grinding machines for wood consumers include primarily their low weight and low cost.
It is this type of equipment that is most often used in domestic conditions. In another way, an angle grinder on a tree is called an angle grinder. It is possible to process with its help not only a beam, a board and a log, but also any other materials. The angle grinder in the household is used not only for grinding surfaces. Very often, metal or stone is also cut with their help.
When choosing an angle grinder, you should pay attention to two main factors: model power and disk diameter. An angle grinder is suitable for polishing wood:
power of 600-1000 W;
with a disk rotation speed of about 6000 rpm.
Experts recommend purchasing such machines with speed control. Tools equipped with a similar function can be used for absolutely all types of grinding.
Such equipment is usually used for various kinds of small work requiring high accuracy. In most cases, direct models of wood grinders are very lightweight. You can hold them during operation, including with one hand. The spindle in this type of equipment is parallel to the housing. Used such machines with nozzles of different types. Therefore, with their help it is possible to perform not only grinding itself, but also engraving, as well as cutting of materials of small thickness.
A wood sander of this design can be used both at home and in large workshops. Power and productivity of tape tools are high. But the processing of the material with their use can only be performed rather crudely.
The main elements of the tape equipment mechanism are:
driven and leading rollers;
Power belt sander for wood can have 500-1200 watts. The rollers in such equipment while moving at a speed of 75-500 meters per minute.
When choosing equipment of this variety, in addition to performance, it is worth paying attention to such a parameter as the width of the tape. You should also look at which model has additional functionality. Very often, belt grinders are supplemented, for example, with such a convenient device as a nozzle for a vacuum cleaner. Also, sometimes equipment of this type comes with a stationary installation and a frame for measuring the depth of grinding.
A wood belt sander is thus used for rough surface treatment. For more delicate grinding, usually vibration equipment is used. The working sole of such machines has a rectangular shape. Therefore, you can use a similar tool, including for thorough grinding of the corners of the workpieces. In the process, the platform of the machine makes a reciprocating motion. Abrasives to the sole of the equipment can be fastened with Velcro or clamps.

Thus, the vibratory sander for wood is designed specifically for finishing. How to choose such a model is a relatively simple question. When buying this type of equipment, a home foreman should pay attention first of all to its power and the number of sole vibrations per minute. Grinding vibration machines can also differ in the amplitude of the platform displacement. The power of this type of equipment varies between 110-600 watts. At home, 250-300 W devices are usually used. The sole of a machine of this type can fluctuate with a frequency of 6-25 thousand times per minute. The larger this indicator, the, of course, the more productive the model.
The oscillation amplitude of such equipment is usually in the range of 1.5-5 mm. For the most delicate processing, those machines are suitable for which this indicator is 1.5-2.5 mm. Equipment with a greater amplitude of movement of the platform is usually used for coarser grinding.
Such a wood grinder works approximately on the same principle as a vibration grinder. The only difference is that for orbital equipment, the platform moves along a more complex path. That is why when using eccentric machines, the surface is almost perfect. Such devices process materials better than vibrating ones. But they are, of course, more expensive.
Grinding machines of any design are often complemented by dust removal systems. On the cost of equipment, the presence of such a function is usually not very serious. But at the same time, processing the material with a dust collector tool can be much better. In addition, the eccentric, tape, angle or vibration sander for wood itself, supplemented by such a system, can last much longer (due to cooling through the ventilation holes during operation).
In addition to the design, when choosing such equipment, you should pay attention to:
- its weight (the lighter the machine, the less tired the hand will get tired);
- productivity (processing speed depends on this indicator);
- casing shape.
The convenience of working with it directly depends on how ergonomic the casing of the model is.
Equipment such as a grinding machine is quite expensive. Therefore, when choosing her, among other things, of course, it is worth paying attention to her brand. You should only buy cars from the best manufacturers with a good reputation. The load on the equipment during operation is significant. Therefore, a poorly assembled tool will most likely last a very short time.
Many companies today supply similar products to the domestic market. But the most popular among domestic consumers is the equipment of such manufacturers as:
Which grinder is best for wood: rating
All of these companies supply different models to Russia. Some of them are more popular with consumers, others less. Top 5 grinding machines, according to domestic masters, looks for 2017 as follows:
Bosch GWS 780 C.
Makita BO50 3 1.
Today, according to most consumers, these are the best wood sanders.
"Makita." the equipment is really popular. Machines of this particular manufacturer are most often purchased by domestic consumers. The advantages of the angular model Makita 9558HN, like most others produced by this company, consumers include primarily light weight, quiet operation and high power. Sanding wood using the Makita 9558HN is, according to home craftsmen, very convenient. The engine during operation of this machine is almost inaudible. Such equipment is relatively inexpensive. an average of about 4000 rubles. Consumers consider the Makita 9558HN’s only drawback to be just a not very convenient power button. Starting and stopping this equipment during grinding is quite difficult.
Interskol UshM-125/900 tool
This is another very reliable, according to many consumers, angle grinder on wood. It is produced and the build quality is pretty good. The advantages of the Interskol Angle Grinder-125/900 equipment are primarily attributed to the simplicity of design, reliability, and low weight. Sometimes it happens that on the packaging an angle grinder power is indicated rather high. In fact, the equipment does not meet the declared indicator. Interskol UshM-125/900 angle grinder is completely devoid of such a drawback. With a declared power of 900 watts, ceramic tiles, for example, it cuts like butter.
Such models are on the domestic market in the range of 2500-3000 p. Their only drawback is overheating during prolonged use.
Bosch corner machines are also being assembled. Their main advantage is light weight. Despite the fact that the Bosch GWS 780 C model is very small, the amount of work done using it can be huge. Also, the advantages of this model are considered to be a smooth start and a quick stop of the engine.
Such machines cost about 3.5-5 thousand rubles, depending on the supplier. The disadvantages of the Bosch GWS 780 C are consumers consider the cable too short, which is included, and the lack of a case.
Consumer opinion on typewriters Makita BO5031
The masters of this eccentric model consider small vibration, the presence of a speed regulator, and quiet operation. Grinding wood with Makita BO50 3 1 can be done very efficiently and fairly quickly. Also, this machine is practically not heated during prolonged use. The disadvantages of the model include low-quality dust bag in the kit. When working with the machine, you must additionally connect a vacuum cleaner.
