ABSTRACT:
A method for fabricating a brake disc assembly comprising the steps of machining a radially extending gage surface (54) on the support flange (34) of an outer race (32) of a bearing assembly disposed around a hub (14) and inserting a fixture post (72) through a spring washer (68) and through the bore (22) in the hub (14). A clamp plate (74) is disposed in engagement with the base (26) of the brake disc with a washer
ut (78) over the clamp plate (74) to place the post (72) in tension to urge the spring washer (68) against the bearing assembly tomaintain the pre-load on the bearing assembly. The outer race (32) of the bearing assembly is clamped with the gage surface (54) drawn against a gage (84) to properly orient the outer race (32) about a fixed axis A. Thereafter, the clamp plate (74) is engaged by rotating jaws (90) which rotate about a floating axis B. The braking surfaces (30) of the rotor (28) are machined (92) while the floating jaws (90) rotate the hub (14) and brake disc relative to the outer race (32), which is held in a fixed position relative to the machining tools (92).
