Our best estimate for the Star Micronics SR-10J is $80,000 - $130,000. 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-10j#price; the request is passed to Star Micronics or an authorised dealer.
Up to 10 mm (25/64 in), which is both the maximum machining diameter and the bar capacity. No optional larger size is listed. For 20 mm stock the SR-20J is the listed alternative, at ø20mm (25/32in) and 2,750 kg.
The standard maximum headstock stroke is 135 mm (5-5/16 in). With the RMGB arrangement it is 105 mm (4-9/64 in). Parts with a longer turned section than the stroke need the bar re-gripped part-way, which costs time and can leave a witness mark.
The main spindle is 2.2 kW continuous and 3.7 kW at 15min./60%ED, with a top speed of 10,000 rpm. The sub spindle also reaches 10,000 rpm and is rated 0.55 kW continuous and 1.1 kW at 15min./50%ED. Keep heavier cuts on the main spindle and use the sub spindle for back-end finishing.
The table lists 6 turning tools on 8 mm shanks, a 4-spindle sleeve holder with 4 front and 4 rear tools, and a 4-spindle back unit. It does not state driven-tool speeds or a drilling limit, so ask for those if your parts have cross holes or milled features.
The machine measures 1,865 × 775 × 1,695 mm and weighs 1,400 kg. Those figures are for the lathe alone. Allow extra length for the bar feeder and access room for coolant and chip handling.
