Our best estimate for the Star NEW SP-20 is $230,000 - $370,000. 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-new-sp-20#price; the request is passed to Star Micronics or an authorised dealer.
The maximum machining diameter is 20 mm (0.787 in). The table lists ø25.4mm (1in) as an option. The spindle speed rows give 10,000 rpm with an option maximum of 8,000 rpm, so ask the dealer whether the lower speed limit applies when the larger bar capacity is fitted.
It depends on the configuration. The standard headstock stroke is 205mm (8in). With MR25 it is 196mm (7-15/16in) and the R.M.G.B. type is 155mm (6-3/32in). The N.G.B. type is listed as bar diameter X2.5 (Max.50mm) (Max.1-31/32in), so it is for short parts only.
The table gives two arrangements: 8 tools with 12mm shanks, or 7 tools listed as 16mmX3, 12mmX4, meaning three of the larger shank and four of the smaller. A job that needs the stiffer, larger tools for heavier turning therefore gives up one tool position.
The main spindle is listed at 2.2 kW continuous and 3.7 kW at 15min/60% ED. The sub spindle is listed at 1.5 kW continuous and 2.2 kW at 15min/60% ED. Both spindles are listed at 10,000 rpm, with an option maximum of 8,000 rpm.
Machine weight is 2,250 kg. The footprint row reads 2,100 × 1,200 × 1,785 and states no unit, so confirm the dimensions and their order from the dealer's installation drawing before laying out the floor.
