Diamond grinding is a mature technology, and there are effective ways a manufacturer can alter the performance of their grinding wheels. Diamond grit size and bonding choices are the primary factors that determine a wheel's performance. Concrete can be soft, hard, abrasive, dusty and brittle etc. There are no two floors are ever the same, typically they are more abrasive when the floor are new or have a high sharp sand content. The more abrasive the floor the harder bond you will need to get the best performance out of the diamonds. The size of the diamond grit in the segment. Typically the smaller the grit the more aggressive the segment will be. The larger the grit the finer the finish will be. The higher the number then the finer the finish will be e.g. 3000 grit will give a highly polished finish.    Screening Emery Emery is the raw material for hot press forming, with high density, large particles, strong hardness, stable cutting, and wide range of objects    Groove design, reduced impedance slip Double chip chute design, fast chip evacuation, reduced resistance slip, lower noise, long-lasting durability, higher efficiency, dry grinding without burning chips    Metal baking process Advanced baking technology, uniform texture, smooth surface, not easy to rust.
