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.
Claims13
Gear shaping machine for machining the toothing of workpieces comprising
- a spindle (11, 41) for receiving a machining tool (60), and
- a drive (40), by means of which the spindle can be driven so as to rotate about the spindle axis (C1) thereof,
- characterised by an arrangement, upon the actuation of which the axial relative position of the spindle with respect to the spindle axis is changed by means of a spindle rotation caused by the drive.
Arrangement for a gear shaping wherein in a first setting of the arrangement, for machining toothing of a workpiece, to be performed by means of a machining tool mounted on a spindle that is driven by means of a motor so as to be rotatable about the spindle axis of said spindle,
- characterised in that a motorised rotation of the spindle in a second setting of the arrangement changes the relative position of a first part (1) of the arrangement with respect to a second part (2) of the arrangement in terms of a direction having components that are axial to the spindle axis.
Gear shaping method for machining the toothing of workpieces, comprising driving a spindle by a motor so as to rotate the spindle about a spindle axis, said spindle being positioned axially with respect to the spindle axis, characterised in that the axial positioning of the spindle is achieved by means of the motorised spindle drive.
