Abstract
A machine for precision working, for example shaving, of the tooth flanks of a toothed workpiece supported rotatably on a machine frame. A tool carrier carries a multi-toothed tool, for example a shaving cutter, and is supported substantially above the workpiece for rotative adjustment of the crossing of the axes of the workpiece and tool, about an axis perpendicular to the workpiece axis. The tool carrier is guided movably in a guide carrier and is driven for longitudinal feeding of the tool. The guide carrier is suspended swingably about a horizontal axis for spherical or conical tooth working. The guide carrier is supported pendantly from a swivel plate which is swingable and lockable about an axis perpendicular to the workpiece axis for adjusting the feed direction. The tool carrier is guided by a guide arm which is adjustable in its inclination and is securable by a pivot member on the swivel plate. Structure is provided for cancelling a portion of the feed movement of the tool toward the workpiece, and the guide arm comprises an inclined swivel guide bar which produces such feed movement of the tool toward the workpiece in response to longitudinal movement of the tool carrier.
