Abstract
A gear grinding machine includes a spindle arrangement, having a rotationally drivable tool spindle for accommodating a tool, having a spindle bearing for mounting the tool spindle in a housing, having a temperature sensor, wherein the temperature sensor is assigned to a bearing outer ring of the spindle bearing of the tool spindle and is adapted to measure a bearing outer ring temperature of the bearing outer ring, having a control device for controlling a grinding process of a toothing to be ground and/or for controlling a dressing of the tool. The control device is adapted to perform a temperature compensation based on a measured bearing outer ring temperature of the bearing outer ring compared to a reference temperature, wherein a temperature-induced axial displacement of the tool spindle is compensated.
