ABSTRACT:
The subject of the invention is a device for clamping tools in the spindle of a machine tool, said device comprising a collet chuck located centrally in the spindle with clamping jaws at the forward end, a spring assembly to generate the necessary closing force and a mechanism overcoming the closing force to open the collet chuck. To avoid the supplying of pressure medium to the spindle and to be able to orient the spindle simply to change tools, the mechanism is located laterally next to the spindle in the spindle head and engages the collet chuck externally as well as an outer ring on the spindle. The outer ring has two notches for engagement of two noses for spindle orientation.
