SW-12RII heading for the highest capability in machining of small diameter workpieces.

  • Simultaneous machining of turning, cross drilling,etc. is possible by the independently controlled,opposing gang-type tool post.
  • The guide bush/non-guide bush selector function ensures optimum machining for both long and short workpieces.
  • STAR Motion Control System is a unique control technology which minimizes non-cutting time.
  • The Star Motion Control System
  • RMGB
  • Balance cut turning
  • GB/NGB switchover
