How does it work?

The work of the grinder on wood material is based on the effect of friction of the device against the material being processed.

The tool can perform its function according to the following principles:

  • vibration, which is characterized by forward and return movements;
  • circular, when the movement is carried out about the axis;
  • combined, in which the first two types are combined;
  • linear, which is typical for tape-type tools.

What is it used for?

Wood grinders are quite common in everyday life and at work. The help of this tool lies in the processing of the material, its leveling, and the removal of old coatings. Using a sander, the master can quickly and efficiently sand and polish walls, floors, restore old furniture, brush wood, and remove varnish and paint.

For each type of work, you can make a selection of the tool model. The devices are capable of performing rough grinding, eliminating irregularities.

Views

There are many types of wood sanders. They perform similar functions, but differ in the final result. On the market you can find professional, hand-held small grinders, drum, circular, flat, electric, disk. All of them perfectly fulfill their tasks and are indispensable devices both for household needs and in the field of professionals.

The main types of tools for processing wood.

Angle grinder

The use of a grinder for work, which is associated with sanding and processing wood surfaces, has been popular for many years. This is a fairly functional tool that easily aligns materials with large dimensions. Of the shortcomings of the operation of such a device, one can single out not the ideal evenness of the surface according to the result of the work. LBM will be an excellent option for log cabins, but not for carpentry work. This is a circular disc typewriter, the nozzles of which can be easily changed.

Petal, disc-shaped circles are the most successful options for this work. Intermediate as well as coarse sanding can be performed when changing attachments.

Tape

Belt sander is so named due to the presence of sandpaper, which is in the form of a belt. The latter carries out continuous movements due to the presence of rollers. This kind of tool is worth using for rough alignments of materials . In order for the surface to be perfectly processed, you will need to use additional equipment. Longitudinal scratches can be removed by step sanding with repeated grit changes. The main advantages of the belt-type tool include good performance. Among the shortcomings, one can single out the inability to get all the structural elements, for example, corners.

The second disadvantage is considered to be a rather large weight of the machine, which causes certain difficulties during operation. Also the grinder is quite noisy, so you must wear headphones while using it . For a shallow depth of grooves, drive the instrument along the fibers. Minor drawbacks of the tape device are insignificant, since the device is functional and productive, therefore it is quite in demand among the consumer.

Orbital

The orbital machine is equipped with a round base and Velcro, where the sandpaper is attached. The discs for such a machine can be easily replaced. The outsole is equipped with many holes through which dust escapes. Litter is collected in bags and cassette-type containers. The operation of the orbiter is based on rotational movements. Thanks to this work, the optimum speed of woodworking is ensured. During the use of the tool, spiral and orbital movements of the platform are performed. This type of tool is lightweight, quiet and easy to use.

Even the corner of the machine can handle a hard-to-reach place, for example, a notch, a cut . The processing of a large wooden surface is also within the power of an orbital sander. Having installed coarse sandpaper on it, the unit can be used for coarse and intermediate sanding. The speed is slightly inferior to the previous version, but users note that it is quite sufficient. The disadvantages of the tool include the inability to process wood in the corners.

Vibrating

This tool is equipped with a rectangle or triangle sole. During its operation, movements occur in a circle, the device vibrates. This type of tool is an excellent option for finishing, under varnishing, before painting. It has a low level of performance. The machine, which is equipped with a rectangular platform, is capable of processing large areas of materials, but it does not make it possible to sand wood near a wall or vertical surface. The triangular platform option is ideal for corners and hard-to-reach places.

Subject to the ingress of grains of sand or solid elements during processing, small circles may remain on the material. This is why the surface must be thoroughly cleaned before starting sanding work.

Oscillating

The device does not belong to wood sanders, but it can perform their functions. The tool has such a grinding ability that is not inherent in other grinders. When installing a triangular sanding platform, the device helps surface treatment in corners and hard-to-reach places . The machine's capabilities include not only removing wood, but also glue from the surface.

Which one to choose?

Ideally, in order to carry out procedures with wood, several grinders are needed, one of which will carry out a rough finish, and the other will finish. Coarse grinding is best done with a tool with an eccentricity of 6-8 millimeters, and for finishing sanding and polishing - 2-4 millimeters. With a limited budget, sanding surfaces can be done with a grinder. The most productive, but at the same time, the cheapest option is the vibratory sander.

If funds allow, then it is worth giving preference to the universal orbital option. Like any other tool, the wood sander is divided into several classes. The household version is designed for short-term intermittent operation. It is recommended to work with such equipment no more than 3 hours a day, while interrupting for 15 minutes.

A professional device is capable of functioning from 8 to 12 hours without interruption. These machines are durable, reliable, and have a good working life. Such equipment is quite efficient. The user has the opportunity to opt for a model with a dust collector, vacuum cleaner or linear motion.

It is necessary to choose a tool that will perform all the tasks assigned to it. The main criteria for choosing a tool include the following:

  • power that has a direct impact on the performance of the equipment;
  • the length of the cord - the larger it is, the more mobile the machine;
  • the presence of overlays on the handle, which improves ease of use;
  • weight - using a heavy tool, you have to make more effort, but such machines are easier to operate;
  • smooth start;
  • the possibility of connecting a vacuum cleaner;
  • regulation of engine speed;
  • protection from overheating.

Operating tips

After purchasing a wood sander, you need to set up the tool correctly. To do this, install the tapes according to the arrows on the back. In the absence of these designations, the ribbons are set arbitrarily. The location of the tape should be strictly in the center. After installation, it is worth turning on the tool and checking it out.

Most grinders are sold with reservoirs that collect dust. If they are not available, the tool can be attached to the vacuum cleaner using an elastic tube. In this way, dust will be removed and may interfere with work.

  • disconnect the tool before cleaning the dust container;
  • before disconnecting the machine from the mains, you need to press the "disconnect" button on the machine.

Grinding machines are units that every owner needs. When choosing them, you should not take into account only the cost or external characteristics, but pay attention to the features of their further use.
