In the process of using automatic polishing machine, sometimes due to improper operation and other reasons, it will have a certain impact on the use of automatic polishing machine. Then, what will be the main impact? The following polishing machine manufacturers will analyze:
Pay attention to the following points when polishing:
Strict selection of abrasives and grinding discs
Before polishing, carefully check the paint surface. Choose different grinding discs and abrasives according to the size of paint scratch, damage degree, paint thickness, wear resistance and other specific conditions.
Water based Abrasives should not cover small streaks. When grinding, try to make the grinding plate contact the paint surface. When the abrasives dry and adhere to the paint surface, spray a small amount of water on the grinding plate for grinding.
Oily Abrasives can cover small flower marks, and it is not easy for the abrasives to dry and adhere to the paint surface. Degrease with degreasing water after grinding, and then make crystal plating and coating products. Otherwise, the crystal plating and coating cannot be well attached to the paint surface, and it is easy to be cleaned.
Polishing machine operation
When the paint scratch is relatively large, you can choose wool disc with coarse abrasive (4 μ m）； For moderate scratches, use coarse sponge ball with medium abrasive (2 μ m）； Fine sponge ball and fine abrasive (0.8) can be used for fine scratches μ m) Polishing operation.
In general, moderate abrasive is used to grind with wool disc, and then fine abrasive is used to grind with sponge ball. "Suit the remedy to the case" polishing can make the paint surface achieve a better effect.
Poor speed control of automatic polishing machine may throw through the paint surface
When polishing, the speed of the polishing machine must be strictly controlled. For skilled technicians, the paint surface of the steel plate can be controlled between 2500-4000 revolutions, and the paint surface of the plastic part can not exceed 1800 revolutions. For unskilled technicians, the paint finish of the steel plate should be controlled between 1500-2500 turns, and the paint finish of the plastic part should be controlled between 1000-1200 turns.
Otherwise, the high temperature caused by too fast rotating speed may damage the paint surface, or even throw through the original paint surface, causing irreparable losses. The effective polishing sequence is from inside to outside, from top to bottom, and complete the operation by circling the car.
Through the above introduction, it can be seen that improper operation will have a great impact on the automatic polishing machine. Therefore, when users use the automatic polishing machine, they should operate according to the regulations, not too casual, but also pay attention to the relevant precautions to ensure the correct operation.
