The price estimate for the Star SU NXT 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-nxt#price; the request is passed to Star SU or an authorised dealer.
Up to 254 mm (10 in) in diameter as standard, and Star Cutter states up to 12 in with a smaller grinding wheel. Grind length is 381 mm (15 in) for end work and 406 mm (16 in) for fluting. With the optional robot, parts are loaded automatically up to 305 mm (12 in) long.
Two, both with automatic HSK clamping. The 15 kW spindle runs to 24,000 RPM and is meant for manufacturing, regrinding and high-speed work. The 28 kW spindle runs to 20,000 RPM and is the all-purpose choice for manufacturing. The specification table is written for the 28 kW (38 hp) version.
Star Cutter integrates a Fanuc 200iD robot as an option. It comes with four pallets, two for blanks and two for finished parts, and it can load, unload and flip parts so that both ends are ground. A single part can weigh up to 6.5 lb (3 kg), and the standard gripper takes diameters from 5 to 32 mm.
The NXT runs the Flexium+ CNC with NUMROTO, a software package for producing and resharpening tools. The rotary axes are programmed in steps of 0.0001 deg, and the linear glass scales resolve 0.00001 mm. For medical tooling Star Cutter also supplies the machine with ESPRIT CAM as a packaged solution.
