ABSTRACT:
A light-weight, highly rigid tool slide for a machine tool is provided which may be machined with a high degree of precision, whereby lateral play or "wobble" of the tool is reduced. The tool slide comprises an elongated slide member slidingly carried in a substantially cylindrical channel formed in the surface of a base member. A cover member covers both the channel and the slide member, which has a flat surface machined therein so as to conform to the shape of the covered channel. The channel in the base member may include an enlarged middle portion to reduce surface contact with the slide member and to provide space for lubricating material. A through-bore may be formed in the slide member to reduce its weight. An encoder monitors the rotational angle of a workpiece and drives a numerical controller and servomotor to move a cutting tool inward and outward in synchronism with the rotation of the workpiece. The numberical controller can be programmed to attain any profile on the workpiece including circular, and non-circular.
