SB-20RII
Information
The SB-20RII offers various improvements to further enhance performance, versatility and ergonomics. This includes additional tool stations, increased power, higher spindle speeds, advanced control features, and improved accuracy. Despite its added capabilities, such as the ability to process components up to 25.4mm in diameter, the SB-20RII has a 10% smaller footprint than the best-selling SB-20R Type G.
Offering a total of 7 axes, the main spindle platen of the SB-20RII includes 6 turning tools, two fixed ER-16 spindles for cross-working, plus a further three modular cross power-driven stations that accept a variety of cartridge attachments. The flexibility of the SB-20RII is further enhanced by its ability to switch between guide bush mode and non-guide bush mode.
Incorporating various technologies to minimise heat generation, the SB-20RII includes Star’s innovative thermal displacement correction technology to optimise accuracy, stability and machining performance. The machine is equipped with Star’s innovative new ECO mode and is compatible with the latest developments including Step Cycle Pro chip-breaking technology, last part completion mode and Easy Edit programming utility.
