The key to the polishing operation of the polishing machine is to try to obtain a greater polishing rate in order to remove the damaged layer produced during the polishing process as soon as possible. At the same time, the polished damage layer must not affect the observed tissue, that is, it will not cause false tissue.
The former requires the use of coarser abrasives to ensure a higher polishing rate to remove the polishing damage layer, but the polishing damage layer is also deeper. The latter requires the use of fine materials to make the polishing damage layer shallower, but the polishing rate is low. A good way to solve this contradiction is to divide the polishing into two stages.
The purpose of rough polishing is to remove the damaged layer of polishing. At this stage, the polishing rate should be reached. Surface damage caused by rough polishing is a secondary consideration, but it should also be as small as possible. The second is fine polishing (or polishing). The purpose is to eliminate surface damage caused by rough polishing and reduce polishing damage to a small amount. The operation of the automatic polishing machine is relatively simple, and the operator only needs to place the object to be polished on the corresponding fixture in advance.
Fix the jig on the worktable of the automatic polishing machine. Start the automatic polishing machine, the automatic polishing machine completes the polishing work within the set time, and then automatically stops, just unload the object from the workbench.
Before polishing with an automatic polishing machine, the distance between the polishing head and the working surface needs to be adjusted. In order to achieve a good contact effect and throw a good effect. Manual waxing can be used during polishing to reduce machine production costs.
