1. Check whether the characteristics of the grinding wheel meet the requirements, and whether the grinding wheel and spindle size are match.

 

2. Assemble the grinding wheel freely on the main shaft of the grinding wheel and not squeeze hard. The inner diameter of the grinding wheel is suitable for the cooperation between the main shaft and the chuck plate. Avoid too large or too small. Cooperate with clean surface, no sundry.

 

3. The plate of grinding wheel should be symmetrical, the radial width should be equal. The tension surface is straight, the side contact with the grinding wheel is full, and the clamping is stable, preventing the two sides of the grinding wheel from being distorted or even broken by the unbalanced force.

 

4. A flexible material liner (such as asbestos rubber sheet, elastic cardboard or leather etc.) between the chuck and the end face of the grinding wheel shall be evenly distributed with the clamping force.

 

5. The tightness of the fastening wheel should be pressed enough to drive the grinding wheel not to produce sliding for appropriate, not too tight. When fastening the big chuck with multiple bolts, it is necessary to gradually tighten the diagonal in pairs in order to prohibit the fastening of bolts in the direction of the circumference, or to tighten one bolt at a time. Fastening wheel chuck can only be used with standard plate hand, and it is forbidden to increase the tightening force by using the long wrench or tapping method.
