Our best estimate for the Star Micronics SR-38 Type B is $250,000 - $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-sr-38-type-b#price; the request is passed to Star Micronics or an authorised dealer.
The table lists the B-axis as a power-driven tool unit with front 3 + rear 3 tools. A driven unit on a B-axis can be set at an angle to the bar, so angled cross holes and inclined milled faces are cut with standard tools instead of fixed-angle holders. It is counted among the machine's 10 axes.
Two figures are listed: 320 mm in the RGB version and 288 mm in the RMGB version. A separate row gives 320 mm (12-19/32 in) as the headstock stroke. Maximum front ejection length is 150 mm (5-7/8 in). Check which version is being quoted before committing long parts.
7 turning tools (5 stationary on the front and 2 on the rear under X3 axis control), an 8-spindle back unit with 8 tools, and the B-axis power-driven unit with three front and three rear tools.
Main and sub-spindle both reach 7,000 rpm. The main spindle is rated 7.5 kW continuous and 11.0 kW (10min./25%ED); the sub-spindle 3.7 kW continuous and 5.5 kW (10min./40%ED). Rapid traverse is 36 m/min on X1, Y1, Z1, X2 and Z2 and 24 m/min on Y2 and X3.
The footprint is listed as 2,740 × 1,315 × 2,120 mm and the weight as 4,300 kg. The SR-32J is listed at 4,100 kg, so the step up to Ø38 mm (1-1/2 in) bar adds little mass.
