ABSTRACT:
An apparatus, operating automatically, for developing a very fine finish on a disk surface which includes a cylindrical toolbit whose cutting edge can be accurately and frequently or automatically rotated so that an unused length of edge can be presented to maintain sharpness and whose shape is amenable to cutting the disk surface on a first pass and burnishing on the staggered return pass and wherein lubricant is fed through a hole in the center of the toolbit to a point between the chip and toolbit surface for the purpose of developing the fine finish together with a turntable for automatically feeding disks to the toolbit to be machined and then withdrawing the disk and storing it.
