A machine for the precision working of tooth flanks of a gear-shaped workpiece. The machine having an internally toothed tool, a tool head angularly adjustable about an axis directed transversely with respect to a workpiece axis for rotationally drivably receiving the tool, means for receiving the workpiece to be machined and means for accomplishing the feeding and working movements of the tool relative to the workpiece in which movable tables existing in conventional machines for receiving the workpieces are avoided with the disadvantages resulting therefrom. The machine also having a frame, a first carriage horizontally movable in an X-direction transversely with respect to a workpiece axis, on which carriage is arranged a second carriage vertically movable in a Y-direction. The tool head is received pivotally about an axis lying in the X-direction in a circular guide in the second carriage. On each side of the tool head there are provided a headstock and a tailstock for receiving the workpiece. The headstock and tailstock are movable on the machine frame in the Z-direction, namely in the direction of the workpiece axis. The headstock is drivable and the tailstock follows correspondingly.

Machine for the precision working of the tooth flanks of gear-shaped

A method and an apparatus for the chamfering of the axially facing ends of toothed cylindrical or conical workpieces in which a cutting tool arranged on a rocking lever is moved back and forth in response to the peripheral speed of the workpiece which constantly rotates about its axis. The cutting edge of the tool acts chip-removingly during each stroke that is directed onto or toward the axially facing surface of each tooth of the workpiece. The cutting edge moves along a circular segment path, the axis of which extends at least approximately parallel to a radial of the workpiece, which radial starts out from the workpiece axis and extends through the tooth which is to be worked or machined.
