CNC sliding head lathes

SR-20J II type B

The Advantages

The upgrade of the SR-20J II type B not only impresses with the possibility of changing the machine from sliding head to fixed headstock lathe. Also with a more stable machine bed and significantly increased power during machining through stronger motors. With 5 drilling tools (front/rear) the spectrum was also extended. The back working was equipped with a Y2 axis and 8 stable tool stations (dovetail guide).

  • FANUC 32i-B control system
  • movable control panel
  • C-axis control as standard on main and sub spindle
  • changeable from sliding head to fixed headstock lathe
  • 2 additional deep drilling stations
  • completely independent backworking
