Description

Technical Field

[0001] This utility model belongs to the field of brake disc processing technology, and in particular relates to a brake disc processing ring cutting device. Background Technology

[0002] Brake discs are the core component of automotive braking systems. The machining quality of their annular groove structure (such as heat dissipation grooves, weight reduction grooves, etc.) directly affects braking performance, heat dissipation efficiency, and NVH (noise, vibration, and harshness) performance.

[0003] Currently, after machining the brake disc ring groove, the cutting tool needs to be reset. The displacement of the cutting tool is controlled by the threaded rod. In other words, the reciprocating motion of the threaded rod needs to be controlled when changing ring materials, which is time-consuming and labor-intensive. The ring cutting action is achieved by manually driving the throttle in conjunction with the ring cutting tool, resulting in low processing efficiency. Utility Model Content
