Star CNC Swiss Type Automatic Lathe
SW-20

Mechanicl and control design to minimize machining time and maximize efficiency.

• Simultaneous machining of turning, cross drilling,etc. is possible by the independently controlled,opposing gang-type tool post.
• The 8-spindle tool post with Y-axis control function exclusively designed for back end working. Front and rear end working are independently controlled to greatly reduce.
• STAR Motion Control System is a unique control technology which minimizes non-cutting time.
