Our best estimate for the Star SH-51 is $260,000 - $380,000. 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-sh-51#price; the request is passed to Star Micronics or an authorised dealer.
The listed figures give a maximum bar capacity and machining diameter of 51 mm (2.008 in) and a maximum machining length of 320 mm (12.60 in), with a guide bushing. Check which collets and bushings come with the machine, since those decide what it can run without further spending.
Up to 9 axes, including Y1, C1 and C2, and 28 tool positions including live tools. The Y-axis stroke is ±15 mm. The wording is "up to", so the axis count depends on how a particular machine was specified. Ask for the axis list of the machine on offer.
The main spindle is listed at 7,000 RPM, the back spindle at 6,000 RPM and the live tools at 7,000 RPM. No motor power is given for any of them, so cutting capacity on 51 mm stock has to be confirmed from the machine's own manual or rating plates.
A 22 kVA electrical supply and a floor that carries 4,200 kg (9,259 lb). No footprint is listed, and a bar feeder for 51 mm stock adds considerable length, so get a layout drawing before committing floor space.
