Abstract
With the method for manufacturing a composite brake disc, which includes a brake disc chamber and a friction ring having an inner profiling, a brake disc chamber blank is introduced into the friction ring. The brake disc chamber blank is then formed into the inner profiling via at least one embossing tool. A composite brake disc permitting a good torque transmission between the friction ring and the brake disc chamber can be manufactured in a cold-forming manner in this way. The forming-in can take place in a hammering manner, in particular by successively implementing a plurality of embossing steps in the region of different profile gaps of the inner profiling. Axial stops can also be simultaneously produced on forming-in. The axial stops serve to stop the brake disc chamber and the friction ring (3) are prevented from axially sliding apart.
