The above composition of the tool post reassures enhanced scalability for complex machining with adequate number of tools.

  • The turret-type tool post can accommodate a 2-spindle type power tool unit with the B-axis control function at a maximum of 4 positions.
  • The 8-spindle backworking unit with the Y-axis control function allows efficient main/back overlap machining.
  • The guide bush and non-guide bush type are interchangeable. The non-guide bush type incorporates a spindle sleeve slide guideway structure for higher spindle rigidity.
  • The Star Motion Control System
  • RMGB
  • XYZ axes control turret
  • Balance cut turning
  • B axis control
  • GB/NGB switchover
