Composite Grinding Machine
Structural characteristics：
X axis drives the multi-functional workhead through linear motodirect drive to complete the lateral feed of the workpieceduring grinding. Z1 axis is the feed axis of the external grinding,
and Z2 isthe feed axis of the internal grinding, C Axis (workhead)adopts servo motor to drive workpiece rotation, which can be combined with X axis and Z axis to complete the grinding of
special-shaped surface. Z axis adoptsintelligent ball screw drive
