Preparation of Grinding Wheel
The preparation of grinding wheel includes: installation, balancing, finishing and dressing. The poor preparation of the grinding wheel will become the root cause of many grinding problems in the future. First of all, install the grinding wheel according to the instructions of the grinding wheel manufacturer to ensure that the grinding wheel is in a good original balance state and the minimum runout before dressing.
Second, be careful during installation to avoid damaging the inner hole of the grinding wheel. The inner hole of the grinding wheel bears huge stress when it rotates at high speed. Improper handling and installation are often the reasons for the bursting of the grinding wheel when it is started.
Third, paper washers must be used when installing vitrified bond grinding wheels.
Fourth, tighten the flange with stable torque and tightness.
After installation, the grinding wheel shall be roughly balanced, trimmed, and finely balanced in sequence before grinding. If the original state of the grinding wheel is very unbalanced and the runout is large, additional dressing and rebalancing are often required.
The good balance of the grinding wheel will keep the grinding surface with good smoothness and prolong the service life. At the same time, the correct dressing will make the grinding wheel maintain a stable grinding surface and grinding effect. The sharpness and shape accuracy of the grinding wheel depend on the dressing method of the grinding wheel. Therefore, the grinding wheel dressing device shall be kept in good working condition at any time, which is the same for single point diamond dresser or motor driven diamond roller.
