Star CNC Swiss Type Automatic Lathe
SR-10J Type C

With improved secondary machining capability and operability, the evolutionary advanced small diameter processing machine is now on market.

• A unique slanted dovetail slideway structure for insreased rigidity of the tool post.
• Both the main spindle and sub spindle include the C-axis control function as standard.
• The manual pulse generator can be optionally set for setup operation.
