Hub shells are blanked out on CNC (Computer Numerical Control) lathes. To produce a hub shell, each is handled 9 separate times. 4 CNC and 5 manual machining operations are performed to produce a hub shell. Each step has its analytical and esthetic quality standards that must be maintained. The hub flanges are canted toward the rim by 5 to 7 degrees, depending on the hub. Spoke holes are placed perpendicular to the surface of the canted flange. The spoke holes in the hub are coined. This process compresses the material directly around the spoke hole by cold forging a convex relief enabling the spoke hole to cradle the head of the spoke. After coining, hubs are placed through a mild heat treatment to stress relieve the resultant work hardening produced in the coining process. The precision boring of the bearing pockets and any other internal machining is then completed. The signature Phil is then cold forged into the hub shell then the final hand polishing is performed
