Abstract

A machine for working the edge of a tooth on a spur, bevel or similar type workpiece. The workpiece is mounted on a workpiece spindle and is supported for rotation as well as reciprocal axial movement. The workpiece spindle on which the workpiece is mounted is supported in a workpiece headstock. The workpiece headstock includes a system of gearing for effecting a continuous rotary drive of the workpiece spindle or, and in the alternative through the addition of an auxiliary housing having auxiliary gearing therein operatively connected with the main gearing in the machine for effecting an intermittent rotation of the workpiece spindle. As a result, two types of machining operations that were heretofore possible utilizing two separate machines are now possible utilizing one and the same machine.
