Tool presetting and/or tool measuring apparatus device, tool presetting and/or tool measuring apparatus and method for operating the tool presetting and/or tool measuring apparatus device

A method for an operation of a tool presetting and/or tool measuring apparatus device, the tool presetting and/or tool measuring apparatus device comprising

• a carrier unit and a spindle unit,
• wherein the spindle unit is supported by the carrier unit,
• wherein by means of the spindle unit at least one object inserted in the spindle unit is rotated around a spindle axis of the spindle unit,
• wherein the spindle unit comprises at least one drive unit for generating the rotation movement of the object,
• wherein the tool presetting and/or tool measuring apparatus device further comprises a further drive unit that is implemented to be separate and/or different from the drive unit,
• wherein the tool presetting and/or tool measuring apparatus device further comprises a holding unit that holds the further drive unit on the carrier unit,
• wherein the holding unit comprises a bearing unit that supports the further drive unit in a movable manner, and
• wherein the spindle unit comprises a coupling unit,
• the method comprising, for the purpose of changing a maximally achievable spindle torque, driving the spindle unit in two differing modes, depending on a coupling position of the coupling unit,
• wherein a movement of the further drive unit by means of the bearing unit activates respectively one of the two modes.
