Abstract
The invention relates to a machine for the gear cutting machining of workpieces, in particular a gear shaping machine, comprising a spindle for holding a machining tool, and a drive by means of which the spindle can be rotationally driven about its spindle axis, and further comprising an arrangement. When said arrangement is actuated, a spindle rotation caused by the drive changes the axial relative position with respect to the spindle axis.
Claims10
Gear shaping machine for machining the teeth of workpieces, said machine comprising:
- a tool spindle (11, 41) for receiving a machining tool (60),
- a drive (40), by means of which the tool spindle can be driven so as to rotate about the spindle axis (C1) thereof,
- a stroke position adjustment arrangement, said arrangement being operable to change the axial relative position of the tool spindle with respect to the tool spindle axis, said change being effected by means of a tool spindle rotation caused by said drive.
In a gear shaping method for machining the teeth of workpieces, the improvement comprising:
- driving a spindle by a motor so as to rotate the spindle about a spindle axis, and
- positioning said spindle axially with respect to the spindle axis,
- characterised in that the axial positioning of the spindle is achieved by means of the motorized spindle drive.
