The control of the feed, the tool-holder slide and the tool position, also during rotation, is controlled by a CNC U-DRIVE gearbox unit. This group ismanaged directly by an axis called “U” of the numerical control of the machining center. A machining center set up in this way allows to hit several different features such as internal and external turning, U-DRIVE grooves, taper bores, concave and convex radius machining, cylindrical and TA-C conical threads and facing for serration.

The centralized supply of coolant does not harm the TA-CENTER of which the internal labyrinth protected by an O-ring. It is advisable to not exceed 40 BAR of pressure. 111
