US 4,493,351 A · Apparatus for copy-machining a workpiece

Abstract

Apparatus for copy-machining a workpiece includes a disk miller assembly acting as a shaping tool and a grinding belt extending between return pulleys and acting as a surface finishing tool assembly, both of the tool assemblies are mounted on pivot arms for pivotal displacement about pivot axes, carried on a common feed device and adapted to be advanced along a workpiece mounted in a clamping device under the control of a scanner scanning a model, the disk miller rotating about an axis extending parallel to the rotary axis of the workpiece as defined by the clamping device. The grinding belt is driven to rotate adjacent the disk miller in a plane extending parallel to the plane of rotation thereof. The pivot axis of the pivot arm associated with the grinding belt assembly is axially aligned with the pivot axis of the disk miller assembly.
