The first step is to adopt the original 30 12A? Point grinder, using the principle of swing polishing operation, grinds off the protruding particles on plastic parts.

The motion principle of this polishing machine can avoid the disadvantage of different cutting effects caused by different internal and external linear velocities in the process of rotary polishing, improve the uniformity and consistency of polished sand marks, and facilitate the removal of sand marks in the next process. Matching sandpaper: 2000#-5000# water sand. )

In the second step, HARAMOTO 450PL pneumatic polishing machine and concentric polishing machine are adopted, and 5000RPM is the best polishing speed. According to the requirements of painting process, wool balls and sponge balls can be selected to remove sand marks and polish, which can easily remove fog shadows.

Extended data:

Polishing does not improve the dimensional accuracy or geometric accuracy of the workpiece, but aims at obtaining smooth surface or mirror luster, and is sometimes used to eliminate luster (extinction). Polishing wheels are usually used as polishing tools. Polishing wheel is generally made of multi-layer canvas, felt or leather, with two sides clamped by metal circular plates, and its rim is coated with polishing agent, which is evenly mixed with micro-powder abrasive and grease.
