Resin-based grinding wheels are more common, and are made by adding a binder to the abrasive, compacting, drying and firing. What kind of resin grinding wheel is of good quality? The answer to this question can be found in appearance.
Visually inspect the grinding wheel for damage or cracks. Grinding wheels with damaged appearance cannot be used. In addition, the two ends of the resin grinding wheel are required to be flat, and there should be no obvious skew.
Look at how dense it is. If there are too many pores, it is estimated that it will not be too wear-resistant.
If there are too few bright spots, the surface will be bumpy. It may be that the bond cannot hold the diamond. Therefore, in the process of grinding, the diamond falls off too quickly. In this way, it will also affect its lifespan and reduce its lifespan.
See if there are cracks inside the abrasive wheel. Holding the grinding wheel in your hand, tap the abrasive wheel disc with a wooden hammer to hear the sound. Grinding wheels without cracks have a crisp sound, and wheels with cracks have a hoarse sound, which cannot be used.
A good abrasive wheel is wear-resistant, sharp, and retains its shape well during use. We can judge and select high-quality grinding wheels for use through the above 4 points.
