Abstract
Abstract A device for smoothing or removing irregularities, such as burrs, from a workpiece, such as a gear. A rotary cutting or skiving tool is first moved by an axially directed movement into contact with the surface on which a deburring operation is to be performed and is then moved in a cutting manner along, and relative to, said surface. The cutting tool is mounted for free rotation about its axis and said axis is adjustable to a position perpendicular to said surface. Preferably said cutter is mounted upon a post suitably supported in a fixed position relative to the machine. Suitable means are provided for effecting the axial and radial movement of the cutter as desired, and same may conveniently be driven by rotation of the workpiece against whose surface the cutter bears. One or more brushes may then be caused to operate against said surface to complete the deburring operation.
