Abstract
A machine tool having an automatic tool changer for transferring tools between a tool magazine and a horizontal tool spindle rotatably mounted in a spindle head and which includes a vertical head which rotatably carries a vertical tool spindle and a horizontal drive shaft connected thereto is removably mounted on a vertical head support. In advance of a machining operation on a top surface of a workpiece, relative movement between the vertical head support and the spindle head is effected in a vertical direction and first and second horizontal directions, so that the vertical head is mounted on the spindle head, with the drive shaft being drivingly connected with the horizontal tool spindle. A tool support station mounted on the vertical head support is provided with two tool grippers each for vertically holding a tool. The tool support station is brought under the vertical head being mounted on the spindle head and selectively presents the two tool grippers in vertical axial alignment with the vertical tool spindle. In this state, the spindle head is moved in the vertical direction and the axial direction of the horizontal tool spindle and enables the vertical tool spindle to return a used tool therefrom to one of the tool grippers and then, to receive therein a new tool from the other tool gripper. A tool transfer device, which cooperates with the tool changer to receive a new tool therefrom and hand over a used tool thereto, is provided between the tool changer and the tool support station and transfers tools therebetween.
