Characteristics of the diamond wheel to decide what

Diamond Wheel is a highly professional product, very few non-professionals for its understanding. Characteristics of the diamond wheel to decide what the majority of users are concerned , but also troubled by a user of important issues. Professionals that features a good diamond wheel is determined by the following factors:
By the characteristics of the abrasive wheel , grain size, hardness , binders , shape and other factors to determine abrasive grinding wheels  the size of the abrasive particle size selection , primarily related to the surface roughness and productivity . When roughing , grinding margin, requires a larger surface roughness values ​​should be used in coarse grains . Because coarse grains , large pores , grinding depth can be larger wheel clogging and fever. When grinding , margin is small, requiring a lower roughness values ​​, you can select finer grit . Generally speaking , the more fine abrasive grinding surface roughness as possible.
Concentration of diamond grinding wheel selection we understand the concentration of diamond grinding it? Refers  masonry drill bits to the concentration of the abrasive layer of the abrasive content . Today we have to say is how the concentration of diamond wheels were chosen , I hope you will like the following content.
① diamond grinding wheel generally 50 % -100 % concentration ; most 75% , the time required to finish higher than 75 %, forming the grinding wheel and requires a long life , can be 100% or more ;
② diamond products in general use 25% -150 % concentration ; cutting blade which coarse-grained , concentrations are concrete saws  generally higher than at the end , that is 25-50 % higher fine-grained ; while other metal bonded grinding wheel generally requires concentration to 50 % to 100 % concentration . Overall, with a higher concentration of coarse , semi- fine grinding with a moderate concentration , and grinding and polishing with a higher concentration .
