Our best estimate for the Star SR-20R II is $200,000 - $330,000. 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-20r-ii#price; the request is passed to Star Micronics or an authorised dealer.
The table gives 25 tool positions, including live tools. It does not break that number down into turning, drilling and driven positions, so ask Star for the tooling layout to see how the 25 are divided.
Maximum bar capacity and machining diameter are both 20 mm (0.787 in), stated in the turning diameter row as ø20mm (25/32in). No optional oversize capacity appears in the table.
On the figures available, tooling. The SR-20R IV Type A/B is listed with a 27-position station and 41 tools, where the SR-20R II has 25 tool positions including live tools. Both are ø20mm (25/32in) machines. The SR-20R IV is listed at 2,600 kg; no weight is given for the SR-20R II.
