ABSTRACT:
The slide 14 carries a support 18 for a plurality of tools, which is secured to a sleeve 34 rotatable and axially slidable on a body 38. The slide 14 carries a series of hydrostatic bearings 36, 39 and 87 to guide rotatably the sleeve 34 and axially the body 38. The sleeve 34 is antulrly tied to the body 38 through a normally closed front clutch 42, 43, which is opened by axially displacing the sleeve 34 with respect to the body 38, through a hydraulic device 44, 47. A reversible electric motor 52 is operated for rotating the sleeve 34 to select the tool, and may be numerically controlled for continuously displacing the tool during a working operation.
