SR-38

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.
  • The Star Motion Control System
  • RMGB
  • Equal load cross guide
  • Balance cut turning
  • B axis control
  • GB/NGB switchover
