The price estimate for the Star SU UTG Series is uncertain: we have no price for it that we can cite and no estimate we can stand behind, so we give no figure. Configuration, tooling, automation and installation move the final price substantially. A specific price can be requested at https://machinetoolindex.com/machines/star-su-utg-series#price; the request is passed to Star SU or an authorised dealer.
The specification table gives a maximum workpiece length of 3,200 mm (126 in) and a Z travel of 2,680 mm (106 in). Star Cutter builds the series in four length variations, from the UTG-600 to the UTG-2400, and describes it as suited to part lengths from 3 mm to 2,400 mm. Ask which variant the table figures apply to before ordering.
Gear cutting tools and other long form tools. Star Cutter lists round, flat and spiral broaches, straight gash hobs, worm gear hobs, shaper cutters, slab mills and rack gear cutters. Maximum workpiece diameter is 305 mm (12 in) and the largest grinding wheel is 203 mm (8 in).
Six, under a NUM 6-axis CNC controller with digital servo motors. X, Y and Z are linear, with travels of 450 mm (17.7 in), 400 mm (16 in) and 2,680 mm (106 in). The A-axis rotates the workhead at up to 60 rpm, the B-axis swivels the grinding spindle 180° in total at 22 rpm, and the C-axis swivels it +/- 30° at 25 rpm.
A grinding spindle that runs at 10,000 rpm with a peak rating of 7 kW (10 hp). Wheels up to 203 mm (8 in) in diameter are mounted by hand as HSK wheel packs. Wheel truing is programmed on the machine, and automatic wheel sticking for unmanned operation is an option.
