Purpose
This machine combines rough grinding (using a horizontal grinding head) with precision grinding (using a vertical grinding head), specifically designed for grinding the external circular arcs of drum brake pads. By using different tooling for various brake pad types, it effectively addresses the previous issue of inadequate surface straightness in brake pads and has received high praise from users.
