Embodiment 1

[0015] A brake disc grinding process, comprising the steps of:

[0016] (1) Coarse grinding: Fix the brake disc of the car horizontally, and then use an angle grinder to grind the surface of the brake disc. When grinding, ensure that the angle between the grinding wheel of the angle grinder and the surface of the brake disc is 15°; (2) Fine grinding: Use 400# dry sandpaper to polish the surface of the brake disc. The parts that cannot be polished by the angle grinder on the surface of the brake disc should be polished 19 times with dry sandpaper. For the inner wall of the air vent on the brake disc, use a ball head brush to polish. , When grinding, make the ball brush squeeze the inner wall and then rotate the ball brush clockwise, rotate the ball brush 23 times clockwise, and then rotate the ball brush counterclockwise; (3) fine grinding: place the finely ground brake disc Under the faucet, use 1000# water sandpaper to polish the surface of the brake disc; take another thin w...

Embodiment 2

[0019] A brake disc grinding process, comprising the steps of:

[0020] (1) Coarse grinding: Fix the brake disc of the car horizontally, and then use an angle grinder to grind the surface of the brake disc. When grinding, ensure that the angle between the grinding wheel of the angle grinder and the surface of the brake disc is 30°; (2) Fine grinding: Use 600# dry sandpaper to polish the surface of the brake disc. The parts that cannot be polished by the angle grinder on the surface of the brake disc should be polished 18 times with dry sandpaper. For the inner wall of the air vent on the brake disc, use a ball head brush to polish. , When grinding, make the ball brush squeeze the inner wall and then rotate the ball brush clockwise, rotate the ball brush 22 times clockwise, and then rotate the ball brush counterclockwise; (3) fine grinding: place the finely ground brake disc Under the faucet, use 1000# water sandpaper to polish the surface of the brake disc; take another thin w...

Abstract

The invention discloses a brake disc grinding process. The brake disc grinding process comprises the following steps that (1) coarse grinding is conducted, specifically, an automobile brake disc is horizontally fixed, then an angle grinder is used for grinding the surface of the brake disc, and the effect that the included angle between a grinding wheel of the angle grinder and the surface of thebrake disc is 15-30 degrees during grinding is ensured; and (2) fine grinding is conducted, specifically, No. 400-600 dry abrasive paper is used for grinding the surface of the brake disc, and the positions, where cannot be ground by the angle grinder, of the surface of the brake disc is ground by the dry abrasive paper for 18-25 times. The angle grinder is used for coarsely grinding the surface of the brake disc, burrs and oxide layers on the surface of the brake disc can be ground off, and the flatness and smoothness of the surface of the brake disc can be further improved through coarse grinding, fine grinding and polishing, so that the brake disc has better usability, through a ball brush and waterproof abrasive paper, burrs and oxide layers on the inner walls of ventilation ports canbe removed, and the effect that the inner walls of the ventilation ports are smooth after grinding can be ensured.

Description

technical field [0001] The invention belongs to the technical field of brake disc processing, and in particular relates to a brake disc grinding process. Background technique [0002] The brake disc can exert an excellent braking effect on the car through the cooperation with the brake pad. At present, the surface smoothness and flatness of the brake disc after the brake disc grinding process are relatively low, and the inner wall of the air vent on the brake disc often still has There are burrs, which will affect the performance of the brake disc. Contents of the invention [0003] In order to overcome the deficiencies of the prior art, the present invention provides a smooth and flat brake disc grinding process on the workpiece surface and the inner wall of the air vent. [0004] In order to achieve the above object, the present invention adopts the following technical solutions: a brake disc polishing process, comprising the following steps: [0005] (1) Coarse grindi...
