ABSTRACT:
Apparatus (10) and a method for finishing a workpiece (12) are performed by a first spindle (24) that rotatably mounts a milling cutter (28) about a central axis A and a second spindle (32) also mounted on the support for rotation about the central axis A to mount a grinding wheel. The first spindle (24) has an annular shape that extends around the second (32), and the apparatus includes a drive (38) capable of rotating the first spindle (24) at a slower rate than the rotation of the second spindle (32) such that milling and grinding operations can be performed at effective speeds. An axial slide (40) mounts the first spindle (24) for rotation and for axial movement along the central axis with the second spindle (32) on which the grinding wheel (36) is mounted located within the annular support.
