How do you compare the single-action polishing machine with the double-action polishing machine?

From:Zhaoqing second machine tool works Co., Ltd.     Release time:2019-03-21

Overview:The single-action polishing machine is concentric and unidirectional, and the running track is also very single. The radius of rotation from the center of the circle to the edge increases sequentially, and the cutting force also increases with the increase of the radius, which means that the edge of the polishing disk has the strongest cutting force. After polishing, it is easy to create a circle mark, which is the sun pattern we are talking about. It is also because of its relatively large cutting force, the efficiency of grinding and polishing will increase, the unfavorable side is that the surface of the paint will be very thin and accelerate the aging of the paint surface.

Motion track comparison

The single-action polishing machine is concentric and unidirectional, and the running track is also very single. The radius of rotation from the center of the circle to the edge increases sequentially, and the cutting force also increases with the increase of the radius, which means that the edge of the polishing disk has the strongest cutting force. After polishing, it is easy to create a circle mark, which is the sun pattern we are talking about. It is also because of its relatively large cutting force, the efficiency of grinding and polishing will increase, the unfavorable side is that the surface of the paint will be very thin and accelerate the aging of the paint surface.

Comparison of heat changes

When the single-action polishing machine is used for polishing, we usually add water to the abrasive or spray the abrasive onto the paint surface, and then spray a layer of water on the abrasive. The purpose is to polish the paint surface and polish it. The heat of the disc is lowered. However, this situation is generally a temporary solution, until the water is consumed by the polishing disc, the polishing disc and the paint surface will still be very hot. Since the polishing disc is only a simple rotary motion, many maintenance workers pursue high efficiency on the polishing disc, and some maintenance workers prefer to throw a position for a long time when polishing, which is more detrimental to heat dissipation. Eventually the paint surface is damaged and the polishing disc is damaged.

In addition, when polishing, ensure that the polishing agent on the paint surface is wet and avoid dry throwing. Because of the polishing agent after drying, the grinding particles are very easy to scratch the paint surface. Therefore, it is generally not allowed to collect the polishing agent very cleanly. After polishing, it is best to show the trace of the cloud-like polishing agent on the lacquer surface, and to observe the polishing effect of the entire lacquer surface through the trace (no scratches, no circles) Traces, etc.) are the best.
