ABSTRACT:
A method is disclosed for imparting relative motion between a tool that is carried by a tool holder and a workpiece on a lathe. According to this method, a feed screw is provided, which has a first end and a second end and a threaded portion near the first end. A tool holder carrying a tool is fixed with respect to the second end of the feed screw, so that axial motion of the feed screw will be translated to the tool carried by the tool holder. A hollow drive tube is also provided, which has an internal diameter large enough to accommodate the feed screw and which is disposed to rotate about its long axis. The drive tube is mounted at a location that is fixed with respect to the workpiece, and a nut that is threaded to mate with the threaded portion of the feed screw is attached to one end of the drive tube. Apparatus for rotating the drive tube is attached thereto, and the second end of the feed screw is locked so that rotational motion thereof is inhibited. The nut is mated with the threaded portion of the feed screw, and the drive tube is rotated so as to impart axial motion to the feed screw as the nut rotates thereabout and to impart relative motion thereby to the tool that is carried by the tool holder. An apparatus which operates according to this method is also disclosed.
