Car polishing removes scratches, coarse grains, marks, anti-white, and other minor defects that appear on painted surfaces. The following is a compilation of car polishing skills, I hope it will be helpful to you.

1、The angle of the polishing disc

Polishing machine tilt relatively large case will make the paint surface heat up fast, and polishing disc side of the part of the friction increased, easy to grind bad car paint, but also make the polishing disc surface contact paint area will become narrow. In general, the polishing disc and the surface should be less than 30 degrees of small angle of inclination.

2、The pressure when polishing

The polishing operation is to polish the lacquer surface evenly as a basis, for this reason, it is necessary to find a way to "control the pressure on the polishing to a certain extent".

Press the pressure is based on the weight of the polishing machine itself, the polishing machine on the plane of its own weight as a basis, do not need to use too much pressure, even in the side of the polishing operation, is also required to use the same pressure as the plane. Do not increase or decrease the pressure, so that it is not easy to produce apertures or scratches that are not removed because the pressure is not uniform and some parts are polished heavily and others are lighter.

When polishing, try to avoid increasing the pressure in the local area, if excessive polishing will form "uneven grinding surface", "polishing dividing line", "polishing scars" and other reasons, due to local heat, will become "polishing burn joint" and other reasons.

3、Grinding range

A grinding range is due to the car body shape and size is not the same, so can be controlled within a certain range, to shoulder width as the boundary, if over use when too wide to rely on arm force use force is not uniform, human physical strength will be difficult to support, will also cause uneven polishing surface (if the use of arm force for too long, and can not be a long time polishing operations).

4, the speed of movement

Polishing machine and disc on the surface of the abrasive in the formation of a more suitable speed, if the speed is too fast, can not control the pressure, but also make the amount of cutting can not reach, there will be "uneven friction".
