Our best estimate for the Star Micronics SR-32JIII Type A/B is $200,000 - $320,000. 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-sr-32jiii-type-a-b#price; the request is passed to Star Micronics or an authorised dealer.
The back working unit. Type A has 6 tools on it. Type B has 8 tools and a Y axis on that unit, so it can position tools off the spindle centreline when working the back end of a part. The rest of the table, including spindles, front tooling and bar size, is given once for both types.
Yes, as an option. The standard maximum machining diameter is 32 mm (1-1/4 in) and Star lists 34 mm (1-11/32 in) as optional. If you run 34 mm stock, state that when ordering so the machine is supplied for it.
Both run to 8,000 RPM. The main spindle is rated 7.5 kW continuous and 11 kW (10 min, 25% ED). The sub spindle is rated 3.7 kW continuous and 5.5 kW (10 min, 40% ED). The sub spindle therefore keeps up on speed but has about half the power, which suits finishing and lighter back-end cuts.
The front carries 6 turning tools on 16 mm shanks, plus a 5-spindle sleeve holder with 5 tools to the front and 5 to the rear. The rear-facing tools of the sleeve holder work on the part held in the sub spindle, in addition to the back working unit.
The machine measures 2,690 x 1,345 x 1,780 mm and weighs 4,100 kg (9,039 lb), with a 275 L coolant tank. The table does not state the electrical supply, and a bar feeder for 320 mm (12-19/32 in) stroke work adds to the length, so ask Star for the layout drawing.
