Our best estimate for the Star Micronics SA-20R Type B is $260,000 - $400,000. 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-sa-20r#price; the request is passed to Star Micronics or an authorised dealer.
The listed B-axis range is +/- 120 degrees, and the axis row reads 5-axis simultaneous, including the B-axis. A rotating tool can therefore be tilted to a programmed angle for angled drilling and milling, and the tilt can move together with the other axes for contoured surfaces.
Both the main and the back spindle are listed at 10,000 RPM. Main spindle power is listed as 3.7 / 5.5 kW (5 / 7.4 HP) and back spindle power as 1.5 / 2.2 kW (2 / 3 HP). The table does not say which duty rating each of the two figures refers to.
The guide bushing row reads yes, with a guide-bushless option. That means the guide bushing is part of the listed machine and running without it is listed as an option, to be confirmed for the particular machine. The table gives no separate machining length for guide-bushless running.
Maximum bar capacity and maximum machining diameter are both listed as 20 mm (0.787 in), and maximum machining length as 200 mm (7.87 in). The machine itself is listed at approximately 2,800 kg (6,173 lbs) with a FANUC 32i control.
