Our best estimate for the Star SR-38 is $350,000 - $570,000. 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-sr-38#price; the request is passed to Star Micronics or an authorised dealer.
Maximum drilling diameter is 23 mm and maximum tapping size is M16 x P2.0. The table does not state the material those limits were set in, so treat them as the upper bound and prove out tougher alloys with a test cut.
Maximum machining length is 320 mm (12.6 in), the same as the headstock stroke. Maximum turning length is 150mm (5-7/8in). The table gives no explanation for the gap. Ask which figure limits a part of your length and diameter before relying on the longer one.
The SR-38 takes Ø38 mm (1-1/2 in) bar at 7,000 rpm and weighs 4,300 kg. The SR-32J takes Ø32 mm (1-1/4 in) bar, Ø34 mm (1-11/32 in) as an option, at 8,000 rpm and weighs 4,100 kg. Main spindle power is the same on both: 7.5 kW continuous and 11.0 kW (10min./25%ED).
7,000 RPM and 5.5 kW (7.4 HP). The sub-spindle power row gives the detail: 3.7 kW continuous and 5.5 kW at the 10min./40%ED rating. Size back-end cuts to the continuous figure for long production runs.
10 axes, including a B-axis. Rapid traverse is 36 m/min on X1, Y1, Z1, X2 and Z2, and 24 m/min on Y2 and X3. The slower pair includes X3, the axis that controls the two rear turning tools.
