Polish or sand wooden furniture, remove rust or get rid of paintwork, wipe putty or grind off burrs - a vibration grinder can handle all this and much more. This process can cause discomfort for many home masters. 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.
The problem of choice
Before purchasing such equipment, it is recommended to immediately understand the variety of grinders, which will allow you to make the right choice.
The vibration grinder is presented for sale in three varieties, among them:
- tape;
- surface grinding;
- eccentric.
Features of orbital grinders
All of them have a certain set of functions and form a cascade of possibilities. With their help, you can treat the surface with rough grinding or treat the finish coat in a delicate way. Belt machines are heavy artillery, they can be used to remove large layers of old coating from large surfaces. The surface grinder is focused on finishing, while the eccentric devices are able to achieve an even higher quality result that borders on polishing.
Belt grinder reviews
Before you choose a vibration grinder, you need to understand the varieties of this tool. Tape, for example, are supplied with an abrasive tape, which is glued together in the form of a ring. Using the work surface, it is necessary to process the base. According to users, such units are characterized by relatively high power, they are reliable and simple. It should also be noted that the belt sander has a solid material movement speed, as well as a low center of gravity. With this device, you can remove a layer of material of several millimeters, form an edge or a rounding.
Many consumers note that with this unit they can easily remove old paintwork or rust. Subject to such a machine will be:
- polymers;
- metal;
- wood;
- mineral building materials.
But remember that high performance is not the best friend of quality. Shells and scratches will form on the surface. Users advise to use surface grinders or orbital grinders for finishing grinding.
Comparison of orbital sanders: BOSCH GBS 75 AE and BOSCH PBS 75 AE models
The Bosch vibration grinder is very popular with consumers today. The first of the mentioned models costs 16,400 rubles, while the second costs 8,600 rubles. Both models have a power of 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 vibratory wood sander has a certain belt length, for the first model, like 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 is powered by 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, but also a vacuum cleaner to the tool. The front support handle can be dismantled for efficient edge finishing. For quick replacement of the sanding belt, a quick-clamping lever is provided, but the centering of the belt is ensured by turning the screw. You can select the required speed for work using the electronic control - this is necessary for processing different materials.
As for the second model, it is equipped with the functionality of automatic centering of the grindingtape, 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 smooth adjustment of the number of revolutions, and it is possible to control the speed of the belt using a switch: it must be equipped with a built-in adjusting wheel.
Feedback on some characteristics of belt grinders
Vibratory grinder, reviews of which may be ambivalent, not suitable for professional use. Sometimes models with low power are not able to endure high loads. That is why it is necessary to become more familiar with the features of the model that you plan to purchase. For example, an important parameter is the speed of the tape, which for tape machines varies up to 550 meters per minute. As a typical example, we can single out the Fiolent MSHL1 model, in which the minimum belt speed is 100 meters per minute.
Some consumers ask the question of why they produce rather 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. If pressed too much, it can simply ruin the workpiece. And if you choose a fast and light machine, you can use it to process large surfaces. But if you still don’t know what loads will be placed on the car, then you should choose a slower model that you can put a little pressure on. Such optionsmore versatile. Even more versatile are the pre-set belt grinders, according to customers, such as the Sparky MBS 976 and the DeW alt DW433.
Reviews about surface grinders
Vibratory grinder "Makita" can be represented by a surface grinder. 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 grinders lies in their moderate cost. The equipment is affordable, and there are simply no dead zones when using these units.
According to buyers, most vibrating machines can boast of a motor whose power varies from 150 to 300 W, such devices are maneuverable, light in weight and compact. Users are advised to pay attention to the amplitude of the sole stroke when choosing a surface grinder. This parameter differs for different models, although it is a relatively small value. Another disadvantage, as buyers emphasize, is the cleanliness of the sole.
For reference
If the machine is running at high speed, you will be able to remove a thicker layer, while if you reduce the frequency, you will achieve an accurate finish.grinding. Some manufacturers, such as Bosch, make the speed of the platform 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 on the PRACTYL vibration grinder for felting
If you need a vibration sander for felting, then you can pay attention to the PRACTYL model, which, according to users, has a fairly reasonable cost and suitable characteristics. Among them, it is necessary to highlight the current frequency of 50 gigahertz, as well as the power, which is 135 watts. It is impossible not to mention the number of revolutions per minute, which reaches 10,000. The grinding surface measures 187x90 mm, and the weight of the equipment is 1.5 kg, which eliminates operator fatigue.
Conclusion
Modern requirements for repair work have reached unprecedented heights, today the statement that the planes should be smooth and even is no longer questioned. Finishes strive for thin layers, because this emphasizes the skill of a professional. Even if you have to work with decorative enlarged building sheet materials, you have to putty them, as well as get rid of the seams, which subsequently involves work where a vibration grinder is involved.
