Our best estimate for the Star Micronics SC-20 is $500,000 – $900,000. 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-sc-20-multi-spindle#price; the request is passed to Star Micronics or an authorised dealer.
No, the table lists actuation as full CNC with no cams, and each spindle is driven by an individual CNC servo motor. Each station has 2 to 3 CNC slides, a number that is configurable. Programming is in Fanuc-compatible G-code on a Fanuc-compatible CNC.
Spindle speed is listed as independent per spindle, up to 8,000 RPM. Because the 6 spindles are not tied to one speed, each station can run at the speed its own tool and diameter call for. The table gives no spindle power figure.
The table gives a typical cycle time of 3 to 10 seconds per part and states that it is part-dependent. It is a range for the class of work, not a prediction. A real figure needs a time study on the actual part, bar material and tooling.
Bar from 1 to 20 mm (0.04 to 0.79 in) in diameter, fed by an automatic magazine bar feeder. The listed materials are steel, brass, aluminum, titanium and plastics. Through-spindle coolant is listed as standard. The machine weighs approximately 7,500 kg (16,535 lb).
