When profiling, a pre-form (flat blank or deep-drawn bowl) is centrically clamped against a tool held in the main spindle by a pressure plate and rotated. The pre-form is taken along by a friction lock. Profiling takes place in several forming stages, with several forming rollers with different outer profiles in sequence applying the pre-form onto the chuck and generating the desired outer profile of the workpiece. The pressure effect of the outer profiled forming rollers plastically deforms the material.
