■Double-column and gantry layout
principle, enclosed frame structure consists of bed, double columns and
■Periphery wheelhead vertical feed,
cross feed movement and grinding wheel dressing feed movement are all driven by
AC servo motor. The machine adopts FANUC 0iMD CNC system.
■Integral casting for machine bed and
■ Bellow-type protecting cover for bed
■Guideways of bed and table adopt
pressure-free automatic lubrication, flow rate can be regulated.
■Table longitudinal drive overcomes the
deflection under gravity of the long piston rod, two buffer structures of tank
and belleville spring to prevent the grinding influenced by the table reversing
■ Wheelhead vertical feed saddle
adopts ball leadscrews driven by AC servo motor after speed reduction, thus to
realize the vertical movement.
