■Double-column and gantry layout
principle, enclosed frame structure consists of bed, double columns and
■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, namely six axes the machine adopts
FANUC 31i CNC system.
■Integral casting for machine bed and table, guideways of
bed and table adopt pressure-free automatic lubrication, flow rate can be
■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
■Periphery wheelhead and universal
wheelhead are driven by AC servo motor with stepless feed regulation.
