Abstract
A method for performing a tool change in a machine tool for machining workpieces, which is provided with a table for clamping workpieces, disposed on a machine frame, with a support on which one vertical or horizontal main spindle is disposed, and with a tool magazine, wherein the tool change is performed at a first peripheral location of the tool magazine which faces the main spindle which is movable in relation to the tool magazine. To achieve the readying of a tool subsequently to be employed without double grippers and without a spread magazine, with short chip-to-chip times and with kinematics which are simplified in regard to construction and control at the same time, at least a first empty position in the tool magazine is provided which is directly adjacent to the position receiving the tool to be used next, a tool is removed from the tool magazine, that this tool is temporarily stored in the area of this second peripheral location, that the tool change is performed directly with the aid of the main spindle in such a way that the already employed tool is deposited in the first empty position of the tool magazine and the tool to be used, which is adjacent to this, is taken from the tool magazine, and that subsequently the temporarily stored tool is again deposited in the second empty location generated in this way.
