Method for manufacturing brake disk for disk brake of motor vehicle i.e. passenger car, involves machining disk pot before adding by loops or precision turnings, and smooth rolling front surface i.e. abutment surface, of pot for wheel hub

摘要

The method involves adding a brake disk pot (14) from a thin walled metal sheet with a friction ring from cast alloy i.e. grey cast iron. The brake disk pot is machined before adding by loops or precision turnings. A front surface (16) i.e. abutment surface, of the brake disk pot is smooth-rolled for a wheel hub. A steel- or hard metal roller (32) is used for smooth rolling. The smooth rolling is prolonged until a rough depth of the front surface amounts to less than 1 micrometer. Surface roughness of the front surface is halved during smooth rolling.
