Item Description

Features


■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, 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 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.

■Periphery wheelhead and universal wheelhead are driven by AC servo motor with stepless feed regulation.
