The present disclosure relates to a method for the gear manufacturing machining of a workpiece in which a hobbing machining of the workpiece takes place to generate a gearing geometry of the workpiece, wherein the workpiece is gear manufacturing machined by gear skiving in addition to the hobbing machining.

A skiving machine has a workpiece spindle and a tool spindle for holding a work wheel to undergo gear cutting, which tool spindle can be rotationally driven synchronously with the workpiece spindle. The workpiece is inclined at an axis intersection angle with respect to the tool spindle for holding a tool retainer. A tool changing system fastened to a housing of the tool spindle is provided, and has a tool carrier, which can be rotated about a tool-carrier axis of rotation and which has carrying plates rotationally arranged around the tool-carrier axis of rotation, each carrying plate having a bearing opening for holding a tool retainer carrying a skiving tool, wherein tool retainers supported in the bearing openings can be selectively coupled to the tool spindle rotation of the tool carrier about the axis of rotation.

A gear cutting machine for gear cutting a workpiece (W) using a gear shaped cutter (17), by engaging and rotating the workpiece (W) that can rotate around a workpiece axis and a gear shaped cutter (17) that can rotate around a cutter axis, while cutting and feeding the gear shaped cutter (17), including: rough cutting at a cross axis angle to the cutter axis, then moving the cutter axis by moving a predetermined angle around the workpiece axis, and performing finish cutting such that the cutter axis has an angle with regard to the workpiece axis in a plane that includes the feeding axis direction and the cutting direction after moving.

The present disclosure provides a worm gear machine, including a workbench, a cutter holder and a cutter holder adjusting system, where the cutter holder includes a big bracket, a first slide rail is disposed on the big bracket, a slide seat in sliding fit with the first slide rail is disposed on the first slide rail, a second slide rail is disposed on the slide seat, a small bracket in sliding fit with the second slide rail is disposed on the second slide rail; and a cutter holder spindle is disposed between the big bracket and the slide seat, a cutter bar synchronously rotating with the cutter holder spindle is disposed between an end of the cutter holder spindle facing toward the small bracket and the small bracket, and a gearbox for driving the cutter spindle to rotate is disposed in the big bracket.
