ST-38 CNC Swiss-type Automatic Lathe

Triple turret design is ideally suited for complex machining of large diameter components for the medical, automotive and aviation industries

  • Simultaneous machining achieved by opposed twin turret design tool post dramatically reduces machining time and independent
  • Triple turrets with 10 stations each, reduce cycle time
  • Deep hole drilling (max. 120mm) on front and rear ends of component parts
  • Equipped with Star Motion Control System for higher accuracy and easier operability
