In the automotive industry, car polishing is a very common situation, so today we will talk about how the Wheel Polishing Machine can be used to complete the polishing work of a car.
Basic method of polishing
1, the disk surface with an angle
When the inclination of the polishing machine is relatively large, the lacquer surface is heated quickly, and the frictional force at the edge of the polishing disc is increased, and it is easy to grind the bad lacquer, and the contact lacquer area of the polishing disc surface is narrowed.
2, the basic method of moving the polishing machine
The grinding operation is based on the uniform grinding of the paint surface. To this end, it is necessary to find a way to "control the pressure of the polishing to a certain extent".
Pushing pressure--based on the weight of the polishing machine itself, based on the weight of the polishing machine on the plane, do not need to use too much pressure, even if the side is polished, it needs to be the same as the plane pressure. Do not increase or decrease the pressure, so it is not easy to produce a part of the throwing part of the light part of the light and the resulting aperture or scratches are not cleared.
The angle between the disc surface and the polishing surface - avoiding the local pressure increase, and the polishing is based on the shape of the disc surface. If it is excessively polished, it will cause "non-uniformity of the grinding surface", "polishing boundary line", "polishing scar", etc., due to local heating, it will become "polishing and burning" and the like.
Grinding range, the range of one-time grinding is because the shape and size of the car body are different, so it can be controlled within a certain range, with the shoulder width as the boundary. If it is too wide when used, it depends on the arm force. The physical strength will be difficult to support, and will also cause unevenness of the polished surface.
The speed of movement, the polishing agent and the abrasive on the surface of the disc form a suitable speed during grinding. If the speed is too fast, the pressing force cannot be controlled, and the amount of cutting is not achieved, and "frictional unevenness" occurs.
The extent of the moving polish - to make the coincidence, the trace left by the polishing disk on the paint is about 1/3-1/4 of the area of the coincident disk.
