Our best estimate for the Star SB-38 is $180,000 - $260,000. 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-sb-38#price; the request is passed to Star Micronics or an authorised dealer.
38 mm (1-1/2 in). The table states it three ways, as 38 mm (1.496 in), as Ø38mm (1-1/2in) maximum turning diameter and as a 1-1/2" (1.500) diameter bar capacity. If your stock is true 1-1/2 in bar, confirm the collet and guide bushing size with Star when ordering.
The maximum turning length is listed as 150 mm (5-7/8 in). That is short relative to the 38 mm bar diameter, so the machine is aimed at compact parts. Longer components would need a model with more turning length than this table shows.
It is rated 7.5 kW continuous and 11 kW on the 10min./25%ED rating, with a maximum speed of 7,000 min-1. The SR-38J carries the same 7.5kW continuous and 11kW rating at the same ø38mm (1-1/2in) size, so power does not separate the two.
Star lists 5 turning tools on the front, of the stationary type, and 2 tools on the rear under X3 axis control. A further row gives Front 5 tools + Rear 5 tools. Live tools are listed at 6,000 RPM. Ask Star for the tooling layout drawing to see how these positions are divided between turning, drilling and driven tools.
Both are ø38mm (1-1/2in) machines with 7.5kW continuous spindle power. The SV-38R is listed with 10 stations, while the SB-38 table lists 5 stationary front turning tools and 2 rear tools under X3 axis control. The choice between them comes down to how the tools are carried, not to bar size or power.
