The ultimate goal of polishing is to find ways to increase the rate of polishing. At the same time, it is not allowed to polish the damage layer to affect the final effect. The former requires the use of a coarser polishing material to grind the abrasive, while the latter requires the use of the finest polishing material to grind the material. What should I do to solve the problem of grinding these two polishing materials at the same time?
When the sandpaper is polished, the sample surface and the polishing disc should be placed in a parallel position. At the same time, the sample should be rotated and moved back and forth along the radius of the grinding wheel to avoid partial wear of the polishing fabric. The grinding powder suspension should be continuously added during the polishing process to maintain the humidity of the polishing fabric.
Polishing and grinding should pay attention to the speed of polishing the grinding wheel should not exceed 500r/ min; because the polishing time should be long, the speed of the turntable can be properly increased when polishing, so the polishing time is to throw away the damage layer of the rough polishing.
