A machine tool has a table (14) movable relative to a head (10) for machining a workpiece (16) mounted on the head (10) by a tool (19A) mounted on the table (14). The table (14) also supports a magazine (17) for blank workpieces (16A), and the table (14) is movable between a first position in which the head (10) and the tool (19A) are in machining proximity and a second position in which the head (10) and the magazine (17) are proximate. The head (10) has a work holder (15) adapted to grip a blank workpiece (16A) at said second position for transfer, by movement of the table (14), to said first position. After machining, the workpiece (16) is correspondingly returnable to the magazine (17). The work holder (15) is mounted on a spindle (12) supported on the head (10) and rotatable for machining purposes. In a modification the spindle (12) supports a tool (23), and the head (10) has a gripper (31) which is separate from the spindle (12) and is used for the transfer of workpieces (16) between the magazine (17) and a work holder (20) mounted on the table (14). |
