Star CNC Swiss Type Automatic Lathe

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.
