SR-20RIIISR-20RIV

The new STAR SR-20RIV for flexible angle working

Complex machining functions adaptable to multiple industries

  • Fanuc controller 31i-B5
  • B-axis (simultaneous working with 5 axis)
  • built-in motor for main and sub spindle

Some of the functions that ensure high productivity:

  • The 8-axis unit with a Y-axis control function can efficiently divide the process for front-side machining and rear-side machining.
  • The latest CNC unit reduces the time required for program processing.
  •  The STAR Motion Control System shortens the non-cutting time. (type B)
