How to show the polishing effect of the outer polishing machine

How can I show the polishing effect of the outer polishing machine ? What is the impact of poor polishing? What issues should you pay attention to when polishing? How can I do the polishing work? Let us Weisheng Machinery bring these problems together into the outer polishing machine.

Paint finish polishing is an important part of car beauty, and the buckling of polishing skills directly affects the role of car lacquer finish. Its role is to remove the fine scratches and oxide layer of the paint surface, to deal with the damage and stains of the paint surface of the car, and the deep construction skills can make the paint surface reach the bright and flawless and restore the new effect. The polishing process of the paint surface is to apply the abrasive to the grinding disc, and then stick the grinding disc to the turntable of the lacquer polishing machine, and finish the lacquer finish according to the lacquer polishing machine. The key points are the adjustment of the rotation speed and the selection of the grinding data.

When polishing, you should pay attention to the following points:

Strict selection of abrasives and grinding discs

Carefully check the condition of the paint before polishing. According to the size of the scratch on the paint surface, the degree of damage, the thickness of the paint surface, the wear resistance, etc., different grinding discs and abrasives are selected.

Water-based abrasives should not cover small flower marks, and the grinding discs should be placed in contact with the paint surface as much as possible. When the abrasive is dried and adhered to the surface of the paint, a small amount of water is sprayed on the grinding disc and then ground.

The oily abrasive can cover small flower marks, and it is not easy to show the condition that the abrasive is dried and adhered to the exterior of the paint surface. After grinding, it needs to be degreased with degreased water, and then can be used for plating and coating products. Otherwise, plating and coating cannot be performed. Very good adhesion to the exterior of the paint, easy to be washed away.

In the case of relatively large scratches on the paint surface, a wool disc can be used with a coarse abrasive (4 μm); a medium scratch can be used with a coarse sponge ball in the middle of the abrasive (2 μm); fine scratches can be selected with a fine sponge ball. An abrasive (0.8 μm) was used for the polishing operation.

Under normal circumstances, the use of medium abrasives with wool disc grinding, and then with a fine abrasive with sponge balls for grinding, "the right medicine" polishing can make the paint surface achieve better results.

Polishing machine speed control is not good, it may be thrown through the paint surface

When polishing, it is necessary to strictly control the rotation speed of the polishing machine. For skilled technicians, the paint surface of the steel plate can be controlled between 2500-4000 rpm, and the plastic part paint surface does not exceed 1800 rpm. For unskilled technicians, the paint surface of the steel plate should be controlled between 1500-2500 rpm, and the plastic part paint surface should be controlled between 1000-1200 rpm. Otherwise, the high temperature caused by the excessive speed may cause damage to the paint surface, and even throw away the original paint surface, causing irreparable damage.

In order to show the good polishing effect of the outer round polishing machine, it is the key to do the above work. Users who don't understand can learn quickly!
