To polish or polish wooden furniture, remove rust or get rid of paintwork, wipe putty or grind deburrs - all this and much more can be handled by a vibrating sander. This process in many home masters can cause discomfort. After all, the operation is time-consuming and monotonous, it is accompanied by the formation of a large amount of dust and noise. But sometimes it cannot be avoided.
Problem of choice
Before purchasing such equipment, it is recommended to immediately understand the variety of grinders, which will make the right choice.
Vibro-grinding machine is offered for sale in three varieties, among them:
- tape;
- surface grinding;
- eccentric.
Features of Vibratory Grinders
All of them have a certain set of functions and form a cascade of opportunities. With their help, you can process the surface by rough grinding or finish the finish in a delicate way. Tape machines are heavy artillery, with the help of them you can remove large layers of the old coating from vast surfaces. The surface grinder is focused on finishing, while the eccentric devices are able to achieve an even higher quality result, which borders on polishing.
Belt Sander Reviews
Before choosing a vibration grinder, you need to understand the varieties of this tool. Tape, for example, are equipped with abrasive tape, which is glued in the form of a ring. Using a work surface, the base must be treated. According to users, such units are relatively high power, they have reliability and simplicity. It should also be noted that the belt vibrating sander has a solid speed of movement of the material, as well as a low center of gravity. Using this device, you can remove a layer of material of several millimeters, form an edge or rounding.
Many consumers note that with the help of this unit, they easily remove old paintwork or rust. Subject to such a machine will be:
- polymers;
- metal;
- wood;
- mineral building materials.
But you need to remember that high performance is not the best friend of quality. Shells and scratches will form on the surface. Users are advised to use surface grinders or orbital machines for finishing grinding.
Comparison of belt vibratory sanders: BOSCH GBS 75 AE and BOSCH PBS 75 AE models
The Bosch vibratory grinder is very popular among consumers today. The first of the mentioned models costs 16,400 rubles, while the second - 8600 rubles. For both models, the power is 750 watts. However, many parameters are still different. For example, the weight of the first is 4.2 kg, while the second is 3.2 kg. The wood vibrating sander has a certain length of tape, in the first model, as in the second, this characteristic is 533 mm, in addition, both can be connected to a vacuum cleaner.
BOSCH GBS 75 AE is a professional tool for vertical, inclined and horizontal surfaces. The unit operates due to an engine with a power of 0.75 kW. You can keep the workplace clean, as it is possible to connect not only a dust collector to the tool, but also a vacuum cleaner. The front support handle can be dismantled, which allows you to effectively process the edges. For quick replacement of the sanding belt, a quick-clamping lever is provided, but the belt is centered by turning the screw. You can select the required speed for work using electronic control - this is necessary for processing various materials.
As for the second model, it is equipped with a function of automatically centering the sanding belt, while the latter is held in the correct position. For convenient and easy replacement of the tape, the manufacturer has provided a fastening system. Electronics provides a smooth adjustment of the number of revolutions, and it is possible to control the speed of the tape using a switch: it is necessarily equipped with a built-in adjusting wheel.
Reviews on some features of belt sanders
The vibratory grinder, reviews of which may be dual, is not suitable for professional use. Sometimes models with low power are not able to undergo high loads. That is why you need to get acquainted with the features of the model that you plan to purchase. For example, an important parameter is the speed of the belt, which for tape machines varies up to 550 meters per minute. As a typical example, we can distinguish the Fiolent MShL1 model, in which the minimum speed of the tape is 100 meters per minute.
Some consumers are asking why they produce pretty nimble cars that have low power. The fact is that a super-productive machine is more difficult to control, it weighs more and has larger dimensions. Pressing it excessively can simply ruin the workpiece. And if you choose a high-speed and light machine, you can use it to process a large surface area. But if you still do not know what loads will be put on the car, then you should choose a slower model, which you can put a little pressure on. Such options are more versatile. According to customers, belt sanders with the ability to preset speeds are even more multifaceted, including the Sparky MBS 976, as well as the DeWalt DW433.
Reviews of Surface Grinders
Vibratory grinding machine "Makita" can be represented by surface grinding option. If we take into account the purity of processing, then these models will be intermediate between orbital and tape. With their help, you can finish grinding a flat surface, which will be based on steel, wood, stone or plastic. The secret to the popularity of vibratory surface grinding machines lies in their moderate cost. The equipment is affordable, and there are simply no dead zones for processing using these units.
According to customers, most vibration machines can boast of an engine whose power varies from 150 to 300 watts, such devices are maneuverable, lightweight and compact. Users are advised to pay attention to the amplitude of the sole stroke when choosing a surface grinder. For different models, this parameter is different, although it is a relatively small value. Another drawback, as buyers emphasize, is the cleanliness of the sole.
For reference
If the machine runs at high speed, then you can remove a thicker layer, while lowering the frequency you will achieve precise finish grinding. Some manufacturers, such as Bosch, make the platform speed adjustable. As an example, we can highlight the Bosch GSS 280 AE L-BOXX model, with which it is possible to adapt to the processing of different types of materials.
Reviews about the PRACTYL vibrating sander for felting
If you need a vibrating sander for felting, then you can pay attention to the PRACTYL model, which, according to users, has a fairly reasonable price and suitable characteristics. Among them, it is worth highlighting the current frequency of 50 gigahertz, as well as the power, which is 135 watts. We cannot but mention the number of revolutions per minute, which reaches 10,000. The grinding surface has dimensions of 187x90 mm, and the weight of the equipment is 1.5 kg, which eliminates the fatigue of the operator’s hands.
Conclusion
Modern requirements for repair work have reached unprecedented heights, today the assertion that planes should be smooth and even is no longer in doubt. Finishing coatings tend to be thin, because it emphasizes the skill of a professional. Even if you have to work with decorative enlarged building sheet materials, they have to be puttied, as well as to get rid of seams, which subsequently involves work where a vibratory sander is involved.
