Description

Technical Field

[0001] This invention relates to the field of brake disc surface processing technology, specifically to a brake disc surface processing equipment and method. Background Technology

[0002] In the surface grinding process of brake discs, grinding is a crucial step to ensure its flatness and braking performance. However, in actual production, when the grinding disc (i.e., grinding wheel or grinding head) rubs against the brake disc surface at high speed, it not only removes excess metal but also leaves a large amount of ash impurities and metal debris on the surface of the grinding disc and the machined area of ​​the brake disc. These impurities mainly originate from free graphite and carbide particles in the cast iron material, as well as fragments shed from the abrasive grains.

[0003] Currently, existing technologies generally employ fixed vacuum cleaners to use negative pressure suction in the processing area to remove dust generated during grinding. However, in actual working conditions, the vacuum cleaners are limited by the fixed position of the suction port and the coverage area of ​​the airflow, and can only effectively suck up fine dust in a suspended state. For metal shavings and sintered impurities with strong adhesion, large particle size, or heavy weight on the grinding disc surface, the negative pressure generated by the vacuum cleaner is often insufficient to overcome their adhesion and cannot be effectively sucked away. If these large particles of impurities are not removed in time, they will be carried back to the processing interface with the continuous rotation of the grinding disc, which can easily scratch the already smooth surface, causing scratches or excessive roughness on the disc surface. It can also increase the degree of clogging of the grinding disc, shorten tool life, and thus seriously affect the processing quality and product qualification rate of the brake disc.

[0004] Therefore, the present invention proposes a surface processing device and method for brake discs to solve the aforementioned problems. Summary of the Invention
