ABSTRACT:
A clamping device for a tool at a machine tool, particularly a die sinking electric discharge machine equipped with a chuck having two pairs of rails projecting from the underside of the chuck and arranged in a rectangular cross. The rails are provided with reference surfaces for adjusting the tool with respect to an x-direction and a y-direction relative to the machine tool, said directions extending transversely to a center line of the chuck. There are provided several posts projecting from the underside of the chuck, which are provided with reference surfaces at their free front surfaces which extend in the x-y-plane as defined by said directions. The rails are eccentric and offset angularly against each other and a tool holder is provided with a plane surface for abutting to the posts, into which two pairs of slots are cut which are in alignment with the rails and provided with elastic lips intended for abutment to the rails. The holder has a center bore with fixing elements for fixing and releasing a draw bar.
