Our best estimate for the Star SB-51 is $200,000 - $290,000. This is an estimate for a swiss-type lathes in this class, not a quote from Star Micronics; configuration, tooling, automation and installation move the final price substantially. A specific price can be requested at https://machinetoolindex.com/machines/star-micronics-sb-51#price; the request is passed to Star Micronics or an authorised dealer.
Maximum bar capacity and maximum machining diameter are both listed at 51 mm (2.008 in). Maximum machining length is 320 mm (12.60 in). The machine is listed with a guide bushing; the table mentions no guide-bushless mode.
The six listed axes are X1, Z1, X2, Z2, C1 and C2, with no Y axis. Live tools run to 5,000 RPM and both spindles have a C axis, so centreline cross holes, flats and slots are within reach. A feature offset from the centreline has to be generated by moving C and X together, which is slower and less direct than a Y-axis move.
The table lists 18 tool positions, a figure that includes the live tools. It does not split the 18 between turning, end-working and live positions, so ask for the tooling layout if a part needs a particular number of driven tools.
Power consumption is listed at 18 kVA and machine weight at 3,800 kg (8,380 lb). Both are listed figures. Check them against the nameplate before the supply and foundation are prepared, and allow separately for a bar feeder sized for 51 mm (2.008 in) stock.
