Problems solved by technology

[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, there is a grinding process in the production process of the brake disc. Through the grinding process, it can The surface of the brake disc has excellent flatness and smoothness, but the current grinding process of the brake disc is more complicated, and the operation requirements for the grinding personnel are higher

Embodiment 1

[0014] A method for polishing the surface of a brake disc includes the following steps:

[0015] (1) Grinding pretreatment: Before grinding, use a deburring tool to remove the burrs on the surface of the brake disc, and then fix the brake disc on a horizontal platform for grinding treatment; (2) Rough grinding: use a 320# grinding wheel installed The angle grinder is used to polish the surface of the brake disc. When polishing, ensure that the polishing direction is consistent. The angle between the grinding wheel and the surface of the brake disc is 16°. For the inner wall of the hole on the brake disc, use model 400# dry sanding paper to adhere to On the thin wooden stick, then turn the thin wooden stick to make the dry sanding paper continue to rub the inner wall, and keep the turning direction always consistent when rotating the stick; (3) Fine grinding: replace the wheel model on the angle grinder with the angle grinder pair of 320# grinding wheel The surface of the brake di...

Embodiment 2

[0018] A method for polishing the surface of a brake disc includes the following steps:

[0019] (1) Grinding pretreatment: Before grinding, use a deburring tool to remove the burrs on the surface of the brake disc, and then fix the brake disc on a horizontal platform for grinding treatment; (2) Rough grinding: use a 320# grinding wheel installed The angle grinder is used to polish the surface of the brake disc. When polishing, ensure that the polishing direction is the same. The angle between the grinding wheel and the surface of the brake disc is 20°. For the inner wall of the hole on the brake disc, use model 400# dry sanding paper for bonding. On the thin wooden stick, and then turn the thin wooden stick to make the dry sanding paper continue to rub the inner wall, and keep the steering always consistent when rotating the stick; (3) Fine grinding: Use 800# sandpaper to polish the surface of the brake disc, especially some corners. The area that cannot be polished by the grind...

Abstract

The invention discloses a brake disc surface grinding method. The method comprises the following steps that (1) grinding pretreatment is conducted, specifically, burrs on the surface of a brake disc are removed through a burr removing tool before grinding, and then the brake disc is fixed to a horizontal platform to be subjected to grinding treatment; and (2) coarse grinding is conducted, specifically, an angle grinder provided with a No.320 grinding wheel is used for grinding the surface of the brake disc, the effect that the grinding direction is consistent during grinding is ensured, the included angle between the grinding wheel and the surface of the brake disc is 10-20 degrees, the inner walls of holes in the brake disc are ground, No.400 dry abrasive paper is selected to be bonded toa thin crabstick, then the thin crabstick is rotated so that the inner wall can be continuously rubbed through the dry abrasive paper, and the turning direction is kept consistent all the time when the crabstick is rotated. The surface of the brake disc are ground for multiple times through the angle grinder and the abrasive paper, thus, the ground surface of the brake disc is good in flatness and the smoothness, the usability of the brake disc is further improved, and the grinding procedures are simple and easy to carry out.

Description

Technical field [0001] The invention belongs to the technical field of brake disc processing, and particularly relates to a method for polishing the surface of a brake disc. Background technique [0002] The brake disc can have an excellent braking effect on the car by cooperating with the brake pad. However, in order to better play the matching effect with the brake pad, there is a grinding process in the production process of the brake disc. The surface of the brake disc has excellent flatness and smoothness. However, the current polishing process of brake discs is relatively complicated, and the operation requirements of the polishing personnel are high. Summary of the invention [0003] In order to overcome the shortcomings of the prior art, the present invention provides a brake disc surface polishing method with simple polishing process and high smoothness and flatness of the workpiece after polishing. [0004] In order to achieve the above objective, the present invention ad...
