MACHINING TOOL FOR MACHINING A FRICTION CROWN OF A BRAKE DISC

摘要

The invention relates to a machining tool for machining along an axis of rotation of a rotary spindle (1) a friction ring (22) of a brake disc (2) comprising clamping means (3) suitable for be rotated by the rotary spindle (1), the clamping means (3) comprising two parts (31, 32) adapted to grip a hub (21) of the brake disc (2), said two parts (31, 32 ) being adapted to rotate the brake disc (2) along the axis of rotation of the spindle (1) allowing the machining of said crown (22), at least one of the two parts (31, 32) of the means clamp (3) having a shape adapted to exert on the hub (21) of the brake disc (2), along at least one circular line concentric with said axis of rotation, a non-uniform distribution of the clamping force .
