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
