Our best estimate for the Star Micronics SW-20 is $170,000 - $270,000. 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-sw-20#price; the request is passed to Star Micronics or an authorised dealer.
It depends on the guide bushing arrangement. The maximum headstock stroke is 205 mm (8 in) as standard and 175 mm (6-57/64 in) with R.M.G.B. Maximum machining diameter is 20 mm (25/32 in) in both cases.
Front: 4 turning tools plus a power-driven tool. Rear: 2 tools, a 4-spindle sleeve holder and a power-driven tool. The sleeve holder carries 4 front and 4 rear tools. The back 8-spindle unit, which serves the sub spindle, takes a maximum of 8 stationary tools and 6 power-driven tools.
Yes, on the listed figures. Both run to 10,000 rpm and both are rated 2.2 kW (continuous) / 3.7 kW (10min/25%ED), so an operation can be moved from one end of the part to the other without losing speed or power.
Bar size, speed and mass. The SW-12RII is the smaller machine, with Ø13 mm (33/64 in) bar capacity, 15,000 rpm and a weight of 2,100 kg. The SW-20 takes Ø20 mm (25/32 in) bar, runs to 10,000 rpm and weighs 3,400 kg. Main spindle power is the same on both, 2.2 kW (continuous) / 3.7 kW (10min/25%ED).
The footprint row reads 2,588 × 1,300 × 1,765 mm and the machine weight is 3,400 kg. Allow extra room for a bar feeder and for chip and coolant handling, none of which the table covers, and check the floor loading before delivery.
