The ST-38 is the ideal sliding head solution for complex mill-turn parts within the 42mm diameter range. Star’s flagship model is packed with functionality that enables challenging parts to be processed in one set-up.

Three 10 station turrets allow up to 70 tools to be loaded, each tool can be easily removed with Star’s unique clamping mechanism permitting fast set-up changes. The main spindle’s lower turret includes an independent Z3 axis. This axis allows two different features to be machined simultaneously (Z1 + Z3) using Star’s “super-position” control mode.

An independent turret is utilized on the sub-spindle where components up to 150mm can be processed and front ejected. STAR MOTION CONTROL is also included to minimize idle time and thus further reduce cycle time.

BENEFITS

• Standard machining diameter 38mm (42mm optional)
• Z1 Stroke of 350mm
• Twin turrets on main spindle for balanced turn-mill operations
• Powerful 11.0 Kw main spindle
• Z3 axis enables SUPER-POSITION control for increased overlap
• YA2 axis on sub-spindle enables off-center pick up
• Tool pre-setter included for easy tool set-up
• STAR MOTION CONTROL to minimize idle time
• Independent turret for sub-spindle for maximum overlap

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
