■Double-column and gantry layout principle，enclosed frame
structure consists of bed, double columns and crossrail.
■Peripheral wheelhead vertical feed, cross feed movement, grinding wheel
dressing movement, universal wheelhead vertical feed, cross feed movement,
rotary indexing movement are all driven by AC servo motor. The machine adopts SIEMENS 840D CNC system.
■Integral casting for machine bed and table, guideways of bed and table
adopt pressure-free automatic lubrication, flow rate can be
■ Double piston rods used to overcome 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.
■Auto-centralized quantitative oil lubrication system for crossrail
