Correct use of pneumatic polishing machine for aut

The main purpose of pneumatic polishing machine is to make up for the small defects of paint film surface such as coarse grain, sandpaper mark, flow mark, whiteness and orange peel after spraying. The treatment method is to grind and polish after spraying, so as to improve the mirror effect of the paint film and achieve the requirements of bright, smooth and gorgeous. The polishing machine is composed of base, throwing plate, polishing fabric, polishing cover and cover. But do you know how to use the pneumatic polishing machine correctly? Let's have a look!

Pneumatic polishing machine, also known as grinder, is often used for mechanical grinding, polishing and waxing. Its working principle is: the motor drives the sponge or wool polishing disc installed on the polishing machine to rotate at a high speed. Due to the interaction of polishing disc and polishing agent and friction with the surface to be polished, the purpose of removing paint pollution, oxide layer and shallow mark can be achieved. Generally speaking, the rotating speed of the polishing disc is 1500-3000r | min, which is mostly stepless speed change, which can be adjusted at any time during construction.

First of all, before using the pneumatic polishing machine, the appropriate thickness of car wax should be used according to the oxidation and damage degree of the automobile paint surface. After the pneumatic polishing machine is leveled, the motor is fixed on the base, and a cushion is used to dot. Then switch on the power supply, put down the handle, press the safety pillar, start the machine switch, adjust the power according to the polishing degree required by the corresponding paint. Generally, it is recommended that the speed should not be too high to prevent some damage to the paint. The working route of the pneumatic polishing machine should be straight. Finally, polishing can be divided into two stages, the first part is rough polishing, that is to remove the polishing damage layer, and the second part is fine polishing, which is to remove the surface damage caused by rough polishing, which can reduce the polishing damage relatively. In addition, it is better to pay attention to the surrounding areas when polishing.
