Abstract
A clamping device for the cutting tools of machine tools having a tool block which can be affixed by clamping elements to the clamping plate of a machine tool carriage, or the like, and which has first guidance means which cooperates with second guidance means of the clamping plate. To prevent bending moments in the tool block and the clamping plate, as well as high surface pressures between the tool block and the clamping plate due to high clamping forces, while still making precise guidance possible, the tool block and the clamping plate have flat clamping surfaces and one of the guidance means is connected to the tool block or to the clamping plate, respectively, so as to be moveable transversely to the clamping surfaces, but immoveable parallel to the clamping surfaces. This ensures that the guidance means always mate without free play, but do not transmit clamping forces.
