SR-38 type B
Complex machining for large diameter workpieces now aim for higher functionality,productivity and accuracy.
- A balance-cut function by X1/X3 axis simultaneous control for high accuracy and high efficiency.
- This machine employs a power-driven tool unit with B-axis control function.
- The guide bush and non-guide bush are interchangeable. The non-guide bush type incorporates a spindle sleeve slide guideway structure for higher spindle rigidity.
