2. The newly received grinding wheel shall have factory certificate or inspection and test mark. If the quality and hardness of the grinding wheel are found before installation, we can customize it according to the requirements of your company. If there are cracks in the particle size and appearance, it cannot be used

3. When installing the grinding wheel, the clearance between the inner hole of the grinding wheel and the main shaft should not be too tight. It should be generally controlled at 0.05 ° C according to the technical requirements of loose fitting/Font>0.10mm

4. Flange plates shall be installed on both sides of the grinding wheel, and the diameter shall not be less than one third of the diameter of the grinding wheel. Gaskets shall be placed between the grinding wheel and the flange plate

5. When tightening the nut, at least 3 special spanners for hardness value shall be selected from different parts, which shall not be tightened too tightly. It is strictly prohibited to hammer with hard things to prevent the grinding wheel from being broken

6. After the grinding wheel is installed, the protective cover, baffle and bracket shall be installed. The clearance between baffle, bracket and grinding wheel shall be kept at 1/Font> within 3mm and slightly lower than the center of the grinding wheel

7. When the newly installed grinding wheel is started, do not be too hasty. First, check it by inching. After 5/Font> it can only be used after 10 minutes of trial run

8. Do not use excessive force during initial grinding to avoid accidents caused by uneven force on the grinding wheel
