Star CNC ST-38

Star

The ST-38, with its triple turret design, enables greater capability for machining components for the Medical, Automotive, and Aviation industries. This machine's capability is ideally suited for extra large parts (38mm diameter) with high speed and universal control. The simultaneous machining achieved by opposed twin turret design tool post dramatically reduces the machining time and independent machining. With two front side turrets and one rear side turret - each with 10 stations each - reduces the cycle time yet further. The ST-38 is equipped with the Star Motion Control System enabling higher accuracy and easier operability.
