Brake disc polishing method

Abstract

The invention discloses a brake disc polishing method. The brake disc polishing method comprises the following steps: (1) carrying out polishing pretreatment, namely firstly removing burrs existing onthe surface of a brake disc by adopting a burr removing tool before polishing; and (2) carrying out coarse grinding, namely polishing the surface of the brake disc by adopting an angle grinder provided with a 120# grinding wheel, wherein consistent polishing direction is guaranteed during polishing, and an included angle between the grinding wheel and the brake disc is 15-30 degrees. The brake disc polishing method disclosed by the invention has the advantages that the angle grinder provided with different types of grinding wheels is used for polishing the surface of the brake disc for multiple times, then the surface of the brake disc is further polished by using high-precision sand paper, polishing precision is high, the polished surface of the brake disc has excellent flatness and smoothness, and good using performance of the brake disc is guaranteed.

Description

technical field

[0001] The invention belongs to the technical field of brake disc processing, and in particular relates to a method for grinding a brake disc. Background technique

[0002] The brake disc can have an excellent braking effect on the car through the cooperation with the brake pad. However, in order to better exert the cooperation effect with the brake pad, the brake disc has higher technological requirements in the production process, especially the brake pad. The surface of the disc must have excellent flatness and smoothness. Generally, the surface of the brake disc has excellent flatness and smoothness by grinding the brake disc. However, currently in the production process of the brake disc, the grinding accuracy of the brake disc surface Neither are high. Contents of the invention

[0003] In order to overcome the deficiencies of the prior art, the invention provides a grinding method for a brake disc with high grinding precision and excellent smoothnes...
