ST-38
Information
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.
