The head (9) is able to tilt from a vertical into a horizontal working position and back again. For tilting, the head (9) is driven by a drive shaft (2), by which a work spindle (10) located in the head (9) can also be driven. Since the tilting drive (5, 4, 3, 16) of the tilting head is derived from the drive shaft (2), no additional indexing mechanism for the tilting head (9) is necessary. A gear (16) of the tilting drive is moved into engagement with a drive shaft (5) by a fluid actuated piston (17) which also disengages the head from an intermediate support (8). The support (8) may also be rotated about the shaft (2) by crossing clamping bolts (33). <IMAGE> |
