STAR SB-12R type G – Year 2021
CNC Swiss Lathe FANUC 0i-TF control system
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.

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
