Description

Technical Field

[0001] The utility model relates to the technical field of polishing equipment, in particular to polishing equipment for aluminum alloy automobile parts. Background Art

[0002] The key to the operation of the polishing machine is to try to get the maximum polishing rate so as to remove the damaged layer generated during polishing as quickly as possible. At the same time, the polishing damaged layer should not affect the final observed structure, that is, it will not cause false structure. The former requires the use of coarser abrasives to ensure a higher polishing rate to remove the polished damaged layer, but the polishing damaged layer is also deeper; the latter requires the use of the finest material to make the polishing damaged layer shallower, but the polishing rate is low. Stainless steel wheels need to be polished many times to obtain the required surface finish. At present, the surface finishing of most automobile wheels is done by manual polishing. During the manual polishing process, it is difficult to polish the narrow space of aluminum alloy wheels. Utility Model Content
