SB-20RII CNC Swiss-type Automatic Lathe

The SB-20RII delivers enhanced performance, versatility, and ergonomics with added tool stations, higher spindle speeds, advanced controls, and improved accuracy. With 7 axes, the main spindle supports 6 turning tools, 2 fixed spindles for cross-working, and 3 modular power-driven stations for various attachments. The sub spindle offers 4 standard stations, expanding to 6. The SB-20RII can operate in both guide bush and non-guide bush modes for greater flexibility.
