Rating of the best models
Summing up the review of the varieties of polishing and grinding equipment, we can confidently say that they are very diverse. Still, there are a number of models that deserve close attention. Among the inexpensive versions, it is worth mentioning the Sturm AG1014P. This device, although marked with the logo of the German brand, is assembled in China. The designers were able to create an excellent mechanism capable of removing dirt and unnecessary coating, as well as artificially aging wood.
An electric motor with a power of 1400 W rotates at a speed of up to 3000 turns per minute. The total weight of the tool is only 3.35 kg. There are soft start options and release key latching. The rotational speed in the loaded mode is maintained at a stable level. A more advanced (professional) option is the Bosch GSI 14 CE.
A similar model of a polishing machine is capable of high-level rough and decorative processing of a wide range of materials. The electric motor, as in the previous version, has a power of 1400 W, and the speed of rotation of the shaft is the same. The handles of the machine are rubberized. The total weight is 3.5 kg. Judging by the reviews, such a tool is quite convenient and safe to use. But this model cannot be called budget in any way.
A significant amount of money will also need to be paid for the Makita BO6040. With this apparatus, you can remove rust and polish various flat surfaces. BO6040 is considered the ideal option for car paintwork. Determination of the number of vibrations and the rate of rotation of the shaft is carried out using an electronic system. Thanks to the smooth start-up, the processing is carried out in a gentle manner.
Ergonomics of the sander
Beginners in the restoration of car paintwork will not be able to work with an inconvenient unit for a long time. Take a closer look at three main models:
- the working unit is located at an angle to the body;
- conventional design, like a drill, with symmetrically located handles;
- straight, with one handle and with the ability to connect an auxiliary.
The first ones are often purchased. Their polishing disc is attached at 90 degrees to the body. And it is more convenient for them to work even with large polishing spots. And one more preference: reliable manufacturers such as Russian Zubr or Interskol, Bosch, Hitachi or Makita - look at the photos of polishing machines from these companies.
Polishing Wheels
Polishingcircles are of different hardness. Most companies produce them in different colors to make them easier to distinguish. Abrasive paste with polishing wheels of different hardness will act differently on the paintwork.
Wool wheels have a stronger abrasive effect than foam and are more suitable for correcting serious paintwork defects. However, woolen circles leave behind small circular scratches, which foam rubber does not. If you polish with a wool wheel with an abrasive paste at high speed to remove defects, you will get such an effect as "holograms". Therefore, this stage should not be the last. For more information about choosing between wool and foam rubber circles, read the article "Wool or foam rubber circles".
Grinding machines from "Bosch"
Many people know the company "Bosch" as a manufacturer of very high quality and reliable equipment. This statement can be fully attributed to the grinders produced by it.They are distinguished not only by the high quality of components, but also by their high productivity.
The devices from this manufacturer use a very efficient fan that quickly cools the motor. Thanks to this, the device can be operated for many hours without fear of overheating. A significant advantage that Bosch grinders have is their ease of use. This is largely due to the presence of an ergonomic rotary handle, which is used in many models of this manufacturer.
It should also be mentioned about a very high quality dust removal system. Thanks to her, you do not have to worry about the cleanliness of the tool during operation. The device is very obedient in work, the speed regulator works instantly.
Model "Vosch GEX 125-1 AE"
The model in question has a low power, which is 250 watts. The minimum number of revolutions it has is 7000. The maximum threshold is 12 thousand revolutions per minute. The vibration amplitude is exactly 5 mm. The working disc has a diameter of 125 mm. It is these abrasive wheels that are installed on all models of grinders from this manufacturer. Bosch sanders differ from their competitors in their low weight, which is only 1.8 kg. The manufacturer positions this model as economical and inexpensive. You can buy it for 7,600 rubles.
