[0002] The caliper disc brake is a type of disc brake. Its rotating element is a metal disc that works on the end face, called a brake disc, and the brake pads and their actuators are installed in a clamp-shaped bracket across the two sides of the brake disc, collectively called a brake caliper. The brake disc and the brake caliper together constitute a caliper disc brake. During the production process, the caliper disc brake needs to be polished using a polishing device to remove surface burrs and make its surface smooth and glossy.

[0003] Most polishing devices will generate a large amount of waste chips floating in the air when polishing the caliper disc brake, which will cause pollution to the working environment and also cause damage to the operator's respiratory tract, endangering the operator's health. Therefore, in response to the above problems, we propose a polishing device for the caliper disc brake. Utility Model Content
