Class Information
Number: 72/82
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")
Description: Subject matter wherein a member turns about an axis concentric (i.e., coincidental) with the work axis, which member has a profile, taken in cross section through the axis, corresponding to a cross-sectional profile of the product to be made, and the work* is disclosed as fixed to the member by a positively acting clamp to turn therewith at the same velocity, so that a tool can engage the work and deform successively presented portions thereof into contact with the profile of the member during turning of the work.
