The machine tool has a table (10) with a vertically movable slide (12) which bears a tool shank (SK1) and hence performs the machining. For replacing the tool shank (SK1) by a new one (SK2), there is a changing device (15) having a changer arm (16) pivotable through 90 degree about a vertical shaft (37). On the changer arm (16) are fitted two securing couplers (17, 18), one above the other, each of which can support a tool shank (SK1, SK2). The tool shanks are taken and transferred to the changing device (15) by a transport device (24), which seizes the tool shanks from above. The changing device (15) grips the tool shanks laterally. When the changer arm (16) is pivoted through 90 degree , the tool shank is pivoted in front of the table (10) so that it can be accepted by the vertical slide (12). |
