Abstract

An apparatus comprising a workpiece spindle for accommodating a gear wheel workpiece, wherein the gear wheel workpiece is rotationally drivable about a workpiece axis of rotation, a first tool spindle for accommodating a first tool, wherein the first tool is rotationally drivable about a first tool axis of rotation, and comprising multiple NC-controllable axes, which are designed to move the first tool in relation to the gear wheel workpiece so that tooth flanks of the gear wheel workpiece can be machined using the first tool, a second tool spindle for accommodating a second tool, wherein the second tool is rotationally drivable about a second tool axis of rotation, a linear carriage, which supports the second tool spindle and comprises an NC-controllable linear drive to be able to linearly displace the linear carriage along a linear guide in relation to the gear wheel workpiece.

Dependent claims

An apparatus comprising:

a workpiece spindle configured to receive a gear wheel workpiece, wherein the gear wheel workpiece is rotationally drivable about a workpiece axis of rotation when received by the workpiece spindle;
a first tool spindle configured to receive a first tool, wherein the first tool is rotationally drivable about a first tool axis of rotation when received by the first tool spindle;
multiple NC-controllable axes configured to move the first tool when received by the first tool spindle relative to the gear wheel workpiece when received by the workpiece spindle for machining tooth flanks of the gear wheel workpiece with the first tool;
a second tool spindle configured to receive a second tool, wherein the second tool is rotationally drivable about a second tool axis of rotation when received by the second tool spindle;
and
a linear carriage configured to support the second tool spindle and comprising an NC-controllable linear drive configured to linearly displace the linear carriage along a linear guide relative to the gear wheel workpiece when received by the workpiece spindle.
