How To Ensure The Polishing Effect Of The Automatic Polishing Machine
How to ensure the polishing effect of the automatic polishing machine
If the polishing is not good, it is very likely that it will be thrown through the paint surface, which will affect the overall polishing effect. What problems should be paid attention to when using the automatic polishing machine for polishing? How can I do the polishing work? Here are some tips to share with you the effect of ensuring the polishing effect of the automatic polishing machine.
Paint finish polishing is an important part of car beauty. The level of polishing technology directly affects the effect of car paint 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 exquisite construction technology can make the paint surface bright and flawless, and restore the new effect. The finishing process of the lacquer finish is to apply the abrasive to the grinding disc, and then stick the grinding disc to the lacquer polishing machine turntable, and finish the lacquer finish by the lacquer polishing machine, focusing on the adjustment of the rotational speed and the selection of the abrasive material.
When polishing, you should pay attention to the following points:
Strict selection of abrasives and grinding discs
Carefully check the finish before polishing. Different grinding discs and abrasives are selected according to the specific conditions such as the scratch size of the paint surface, the degree of damage, the thickness of the paint surface, and the wear resistance.
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 appear that the abrasive is dried and adhered to the surface 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, the plating and coating cannot be performed. Very good adhesion to the paint surface, 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.
The effective polishing sequence is from the inside to the outside, from top to bottom, the turn of the car to complete the work.
In the actual operation process, the above method can not only ensure the polishing effect, but also further improve the polishing rate, which can be said to have many benefits.
