Abstract
Description
Technical Field
[0001] This utility model relates to the field of rotary fixture technology, and in particular to a self-rotating fixture for polishing. Background Technology
[0002] After various automotive parts are die-cast, the semi-finished parts need to be post-processed. The traditional polishing process is done manually, which is not only costly in terms of labor but also inefficient. When the parts are small, various curved surfaces are processed by manual polishing, which is not only inefficient and time-consuming but also makes it impossible to control the yield, which can easily lead to a large number of semi-finished parts being scrapped.
