Abstract
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.
