st-20ST-20

The latest model is ST series equipped with the highest level specifications and functions in the Ø 20 class aimed at high productivity

Simultaneous machining such as turning, milling, etc. by opposed twin turret tool post reduces the machining time drastically.

Overlap machining of front and rear ends by back working turret tool post for shorter machining time.

Several tools mounted on one side of the turret station for reducing the number of times of indexing and tool change time . 

The STAR motion control system for reducing the control path change over time, enhancing auxiliary functions and reducing the processing time.
