1.Longitudinal movement of grinding head with guide screw. Precise and convenient control of 

   grinding removal by turning the handwheel with scales. 

2.The shim plate can be slightly adjusted to accurately regulate the degree of parallelism 

   between the grinding face of workpiece and the end-face of grinding wheel so that the 

   processing requirements can be fully satisfied with a high precision of grind. 

3.The lateral shifting of the trailing bar adopts the gear-rack structure to adapt to 

   different grinding speeds, with an easy operation.
