SW-20
The Continuation of ECAS-20
The pursuit of reduced idle times both mechanically and electrically through the latest software allow complex components to be manufactured in the fastest possible times to improve both production output & profitability.
Advantages:
- Simultaneous machining (turning & drilling, etc.) by opposing plattens leads to shortened machining time.
- The 8-spindle tool post (with Y-axis) exclusively designed for back working. Front and back working are independently controlled to greatly reduce machining time.
- The Star Motion Control System ensures an uninterrupted tool path.
- A tool post (with Y-axis control) exclusively designed for 8-spindle back working is equipped.
- A variety of new functions, such as manual handle retracing, program check, code help and others are added to help the operator.
