ST-20
Three turrets allows ultra high speed and flexible machining of complicated components.
- Simultaneous machining such as turning, milling etc. achieved by opposed twin turret design tool post dramatically reduces the machining time.
- Independent machining of front and rear ends by backworking turret reduces the cycle time yet further.
- STAR Motion Control System is a unique control technology which minimizes non-cutting time.
