Features
■ Double-column and gantry layout
principle, enclosed frame structure consists of bed, double columns and
crossrail.
■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 table, 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
table reversing impact.
■Wheelhead vertical feed saddle adopts
ball leadscrews driven by AC servo motor after speed reduction, thus to realize
the vertical movement.
