2 U-TRONI eneral features XS N X Y Z W U M= motor T= transducer T U TRONI M U T M W INTRF U-TRONI are medium and large N heads, controlled by the U axis of the N of the machine tool for inner and outer facing, undercutting, cylindrical and conical boring and threading, concave and convex radiusing machining, by interpolation with other machine axis. These heads can be fitted to boring machines, to machining centres and to special machines manually, automatically or by means of palletized systems. These heads are manufactured in 8 models, from ø 8 mm to mm and all of them have internal coolant supply. The versions ø 8 and are provided with two counterweights which allow machining at high RPM with unsignificant vibrations. U-TRONI special versions, with two slides and with self-balance counterweights can be supplied on request. Fixed toolholders are applied on the slide, with manual or automatic tool change. 4

Interchangeable arbor. Flange 6 IMPORTNT NOT The kinematic system of the U-TRONI is made up of a kinematic chain complete with differential or epicycloidal unit where: - U-TRONI 8 and one motor revolution=.5 mm radial shift of the slide. One revolution of the transducer =.5 mm radial shift of the slide. - U-TRONI 5, 4, 5 and 6 one motor revolution=. mm radial shift of the slide. One revolution of the transducer = mm radial shift of the slide. - U-TRONI 8, one motor revolution=.4 mm radial shift of the slide. One revolution of the transducer = mm radial shift of the slide. etween the transducer and the toolholder slide there is a max radial reversal play in the kinematic chain of approximately.5 mm, thus in order to be precise positioning must take place in a single direction, and be included during programming For safety reasons, install a microswitch on the machine that signals when the U-TRONI is mounted and limits spindle rotation as follows: UT 8 max. RPM UT max. RPM 8: per stroke +- 5 mm RPM 6: per stroke from 5 to 7.5 mm UT -5 S max. RPM 5 UT 5-4 S max. RPM 4 UT 5-5 S max. RPM 5 UT 5-6 S max. RPM 5 UT 8-8 S max. RPM UT 8- S max. RPM 6
