The shaping head is mounted to the infeed slide using the preloaded roller rail system mounted to the cross rail. The infeed slide is positioned with a precision ball screw. The shaping head design offers CNC quick return, back off and cutter offset, tapering, crowning, and contouring.
The work spindle is a self-contained unit mounted on precision radial/axial roller bearings and has infinitely variable speeds of 1 to 40 RPM via an integral liquid-cooled torque motor with 1,800 Nm continuous torque.
Lubrication for the linear guideways and ball screws is automatic and CNC. Standard coolant tank capacity is 50 gal.
