[0003] The caliper casting blank is a die-casting product, which needs to be manually polished with a cutting machine. However, this has low work efficiency, and the hard burrs on the flanging are easy to scratch workers and damage the castings, and the burrs are not cleaned cleanly.

Considering that the riser part of the caliper workpiece grows in the narrow opening of the workpiece, the polishing requirements are special and it is difficult for the robot gripper to handle it, so a special polishing machine is added to process this place. Before the casting enters the polishing unit, the riser root on one side of the caliper opening is first ground on a special machine. This scheme aims to propose a special machine for grinding the riser root that can be automatically polished to improve the polishing efficiency of the workpiece. Utility Model Content
