ABSTRACT:
A rotary chipping head with multiple knife structures distributed about its periphery. Each knife structure includes an end-located chipping knife with a cutting edge movable in a plane disposed perpendicular to the axis of rotation of the chipping head. End-located facing knives are interspersed with the knife structures for producing a smooth face in the work being processed. Anvils preceding the facing knives produce compression in the work being processed. Detachable facing elements mount the facing knives and the anvils.
