The evolution for complex turned parts advanced technology

The new SR-20RIII appears in a new futuristic design and offers the latest in

  • newest FANUC control type 300 is built-in spindle with cooling for main side
  • automatic programme optimisation
  • servomotor for adjustment of collets on main/back side

Further, there are many additional very efficient functions

Those helped to considerably improve the working ergonomics:

  • rapid speeds of 35 m/min
  • 2 additional tool stations for deep drilling up to 100 mm
  •  more efficient and faster
