Tool-clamping device used for clamping machine tool for cutting large workpiece e.g. transmission housing of wind turbine, has additional clamping units provided on base and around rotational axis of tool spindle
The tool-clamping device (18) comprises a base (22) on which a tool spindle (23) is mounted for rotationally driving a tool. The tool is tensioned by a clamping unit coupled with a drive unit (24) for rotating the clamping unit about a rotational axis of the tool spindle. Several additional clamping units (44-47) are provided on the base and around the rotational axis of the tool spindle, for additional clamping of the tool. An independent claim is included for machine tool.
