AI Technical Summary
Existing technologies cannot guarantee the parallelism requirements of brake pads during grinding, especially the problems of uneven parallelism and thickness caused by uneven steel back during grinding, which make it difficult to meet the strict tolerance requirements of 0.13mm or even 0.1mm.
A precision grinding wheel structure for improving the parallelism of brake pads is adopted, including a grinding wheel base and a grinding layer with a width greater than that of the brake pad. The grinding layer is composed of a diamond layer and is fixed to the surface of the grinding wheel base through electroplating or sintering processes, ensuring that the upper and lower ends of the brake pad are pressed down, avoiding jump and meeting the parallelism requirements.
This achieved the desired consistency in brake pad thickness and a parallelism of 0.03mm, while keeping costs within an acceptable range and improving grinding efficiency and finished product quality.
