CNC sliding head lathes

SB-20R type G

The Advantages

The SB-20R is a further development of the SB series and is an attractive cost-effective solution.

The range of machining possibilities of the SB-20R is extended through power-driven tools on the rear side.

The sliding head automatic lathe can also be converted to be a fixed headstock lathe to therefore reduce costs for conventional turning.

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

Kinematics & Tools

  • 6 (7) turning tools
  • front and rear side each with 4 drilling tools
  • 4 (5) power-driven tools on the tool post
  • 4 + α power-driven tools for backworking
  • 7 axes
