ABSTRACT:
An adapter for a grinding tool suited for standard attachment to a grinding machine is provided. The standard attachment comprises a receiving threaded bolt and an attachment nut for securing a supplementary tool in a usual manner. The grinding machine includes a motor-driven hollow spindle, to which a counterflange is firmly connected. A bolt receiving the standard attachment at one end thereof and guided by a flange can be screwed into the hollow spindle. Spring elements are provided for pressing the bolt and thereby the flange against the counterflange of the hollow spindle, in order to secure the standard attachment to the grinding tool. The hollow spindle can be axially displaced by a manual actuating device between an assembly position, in which the adapter may be taken off or attached, and a secured position, in which the adapter is secured against rotation and against axial movement within the hollow spindle.
