Abstract
A boring, milling, thread cutting or analogous machine has a frame for a work supporting table and a first carriage which is reciprocable in the X-direction. The first carriage supports an open-and-shut magazine for a supply of spare tools as well as a second carriage which is movable in the Y-direction. The second carriage supports a headstock which is movable with a vertical tool spindle in the Z-direction. The magazine is opened in automatic response to movement of the second carriage in the Y direction and to a predetermined position in which the tool spindle can be relieved of the tool thereon by being lifted upwardly. An indexing mechanism of the magazine then places a selected tool into the path of downward movement of the spindle so that, when the spindle descends, the freshly selected tool is automatically coupled thereto. The second carriage is thereupon moved in the direction of the Y-axis to enable the magazine to become shut. A further selected tool is placed in a position adjacent to the locus of transfer onto the tool spindle while the tool which at such time is attached to the tool spindle is used for the treatment of a workpiece on the table. The device which actually opens the magazine in response to movement of the second carriage in the direction of the Y-axis to a predetermined position is a cam which spreads apart portions of elastically deformable guide rails provided in the magazine and defining an elongated path for the indexing of spare tools therealong.
