Abrasive cloth wheel is a common grinding tool, as long as the proper use can bring good results, sometimes we can find that the performance of emery cloth wheel has advantages and disadvantages, so what factors affect the performance of emery cloth wheel?
The first is abrasive: abrasive is an important raw material for the production of emery cloth wheel, it bears the cutting work. Therefore, abrasives must be sharp and have high hardness, good heat resistance and toughness. Second grain size: grain size refers to the abrasive grain size. grain size is divided into two categories: abrasive and micro - powder. Another is the hardness: the hardness of the emery cloth wheel refers to the grinding grain on the surface of the emery cloth wheel under the action of grinding force to fall off the level of difficulty. The hardness of emery cloth wheel is soft, showing that the abrasive grain of emery cloth wheel are easy to fall off, while the hardness of emery cloth wheel is hard, showing that the abrasive grain are difficult to fall off. Hardness and abrasive hardness are two different concepts.
The same kind of abrasive can be made into emery cloth wheel with different hardness. Grinding and cutting is the obvious difference between emery cloth wheel with "self-sharpness", the choice of emery cloth wheel hardness, in fact, is the choice of its self-sharpness, sharp grinding grain do not fall off too early, also do not blunt still do not fall off.
