1. There are 4-servo axes: X axis of workpiece radial feed, Z axis of workpiece axial feed, Rotary axis A of grinding head and workpiece indexing axis C. 

2. X,Z-axes with linear roller guideways. High precision.

3. A axis with combined bearing to guarantee the accurate positioning for the helix angle of the grinding head. High rigidity.

4. C axis adopts double worm clearance mechanism to ensure accurate division.

5. Standard paper bag filter system and coolant system.
