1. Users should use special roller dressing devices as much as possible, and ensure that the machine tool and dressing device have sufficient accuracy and rigidity;

2. The fit gap between the roller and the mounting mandrel should be ≤0.005mm;

3. The linear speed ratio between the roller and the grinding wheel being dressed is 0.4 to 0.7;

4. The user must correctly install the roller and accurately adjust the runout of the roller. After installation, the end runout of the reference end face of the roller and the radial runout of the reference outer circle should not exceed 0.002mm-0.003mm;

5. Please use the heat sleeve method to install the roller. When installing and disassembling the roller, it is strictly forbidden to directly knock the roller to prevent the roller profile or reference from being damaged;

6． The coolant pH value is controlled at 8.5-8.8;

7. When the roller is dressing the grinding wheel, the roller should be ensured to have reliable and sufficient cooling;

8. During dressing, the impact of the grinding wheel on the roller should be avoided to avoid damaging the accuracy of the roller;

9. In order to extend the life of the roller, when the roller is dressing the grinding wheel, the feed amount for each dressing should not exceed 0.02mm as much as possible;

10. When the roller is not rotating, it cannot contact or trim the rotating grinding wheel, which will cause the loss of accuracy of the roller;

11. When dressing the grinding wheel with the diamond roller, you must follow the action program of fast forward (do not hit the grinding wheel) → slow forward (feed at the required cutting speed) → light repair → exit. No wrong steps are allowed, otherwise the life of the roller will be difficult to guarantee.

12. If you have any questions during use, please contact the manufacturer in time. Please do not process or modify the roller to avoid loss of accuracy of the roller.
