Our best estimate for the Star Micronics SA-20R Multi-Spindle Automatic is $600,000 – $1,050,000. This is an estimate for a multi-spindle automatics 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-sa-20r-multi-spindle#price; the request is passed to Star Micronics or an authorised dealer.
The listed figure is 6 spindles, served by 6 cross slides (one per position) and an end-working unit. Maximum bar diameter is 20 mm and maximum spindle speed is 7,500 rpm. These are listed figures that have not been confirmed against a Star page.
No, the table gives 18 kW as the total installed spindle motor power. It does not break that down by spindle, so the power available at one position cannot be taken from this figure. Ask for the per-spindle rating if a single heavy cut decides whether the job fits.
Weight first: the listed figure is approx. 11,500 kg, which calls for a planned rigging route and a floor rated for the load. The table describes the machine as compatible with a front-loaded magazine bar feeder but does not state that one is supplied, so confirm what bar loading equipment comes with a particular machine.
