Class Information
Number: 72/83
Name: Metal deforming > By use of tool acting during relative rotation between tool and work about internal center (e.g., gyrating or rotating tool) > During rotation of work > Caused by work-holding, shape-imparting form (e.g., for "spinning") > With means causing cooperating presser member to traverse form surface
Description: Subject matter wherein the tool co-acts at any particular instant of time with a portion of the face of the turnable member and said tool is moved (a) relative to a point on the axis of said member and (b) along the face of the member.
