abrasive hardness _ size _ Strength

Abrasive particle size refers to the size of the abrasive particle. Abrasive particle size according to the size of its divided abrasive, grinding, powder and superfine four groups. Among them, these grinding wheel china  two sets of abrasive grits and flour particle size numbers with each English
Inch mesh sieve length number that is marked by the number of numbers in the upper right corner of granularity the "#" symbol. For example 240 #, is the length of every inch of screen holes 240, the value of size number greater, indicating that
The finer grits. The  Abrasive paper two sets of abrasive powder and superfine grain size numbers is to represent the actual size of the particles, and its logo is the particle size numbers preceded by a letter "W". Sometimes it can be converted into the sieve
Number. For example W20, is the actual size of the abrasive particles between 20μm ~ 14μm, which number is 500, and mesh #. In a variety of abrasive particle size and there were coarse, medium and fine particles of different. Abrasive powder in capsules is the basic size, abrasive grinding capacity is to determine the main factors in the Lido large proportion of the composition. Practice has proved
Description: After centrifugal separation after grinding abrasive powder their ability to score before the election by 20%. In fine abrasive grinding plays the role of a small particle size in addition to the adverse external grinding workpiece quality, but also reduce the grinding efficiency, should
Grain size to minimize their number. Therefore, the grinding efficiency and the quality, the abrasive particles  cut off wheel are uniformly required. Particle size # 12 # 80 grit group, larger particle size, does not apply to research and
Grinding abrasive.
Abrasive hardness
The hardness of the abrasive surface of the abrasive refers to the ability to resist local external action, and abrasive (such as stone) is the hardness of the abrasive binder in the solid level of the external force, which is one of the basic characteristics of the abrasive. Is the use of abrasive grinding and machining of the workpiece is ground to achieve the hardness difference, the higher the hardness of the abrasive, the stronger its cutting ability.
Abrasive strength
Refers to the strength of the abrasive abrasive firm level itself. That is, when still quite sharp abrasive blade, can withstand external pressure without the ability to be broken. Abrasive intensity difference, it is fast abrasive grinding, cutting capacity, short life. This requires in addition to high hardness abrasive grains, but also has sufficient strength, in order for better grinding.
