CNC automatic lathes

SB-12R type G

The advantages

The machining spectrum was further expanded by flexible selection of the power-driven tools on the tool post of the SB-12/20R G. The main spindle is fitted by power-driven front drilling unit and saw unit as well as polygon unit and thread whirling unit. The use of power-driven tools on the rear side are now standard.

  • FANUC 0i-TF control system
  • C-axis control as standard on main and sub spindle
  • completely independent backworking
  • changeable from sliding head to fixed headstock lathe
  • movable control panel
  • low space requirement
  • ideal replacement for cam-controlled lathes
