ABSTRACT:
A caliper machining apparatus for machining a caliper for a disc brake is disclosed which comprises: a cutter for cutting the caliper, a facing mechanism for positioning and facing the cutter relative to the caliper, and a caliper holding jig. The jig supports the caliper at several surfaces for machining by the cutter. The facing mechanism includes a hollow rotary spindle, a facing head fixed to the rotary spindle, a slider movable only in a diametric direction of the facing head, and slidingly moved in eccentric relation with a rotary center of the rotary spindle and a facing shaft passing through the rotary spindle. The facing shaft is allowed to rotate with the rotary spindle but to be displaceable in an axial direction relative to the rotary spindle. The rotary spindle is rotated by a main motor. The facing shaft is moved in the axial direction by the rotation of a facing motor.
