[0015] 1. In the utility model, the processing space during grinding is isolated by structures such as slideways, sliding plates, rotating rods, torsion springs, etc., so as to improve the problem that debris splashes when the parts are ground, and the debris is easy to splash to the staff, thus causing certain danger of injury to the surrounding staff. At the same time, it is convenient for personnel to disassemble and clean the isolation mechanism, so as to improve the problem of a large amount of internal waste chips due to long-term use and the inconvenient cleaning of the narrow internal corners.

[0016] 2. In the utility model, the width of the chuck is adjusted through the limit opening, chuck, paddle and other structures, which is convenient for customization according to the size and width of the polished parts. This improves the traditional polishing process where the chuck is smaller than the chuck, resulting in the chuck being polished closely and damaged during polishing. At the same time, the chuck can be easily disassembled and assembled, which is convenient for later maintenance and only requires single replacement, reducing the overall replacement cost.
