Abstrakt: We have studied performance of AS20 diamond powders to be used in grinding wheels and have found the ways to improve it through changing the dimensional and physico-chemical characteristics of the powders. It is demonstrated that the wheel wear is influenced by separating the narrowest range of grain sizes 100/90 and providing a uniform powder with a certain grain shape factor; it is preferable to use diamond grains with higher values of the shape factor. It is shown that after diamond powders are separated into magnetic and non-magnetic fractions there is a difference between the fractions in the physico-chemical state of the grain surfaces, and it is preferable to use non-magnetic fractions in resin-bonded wheels in order to improve the wheel wear resistance.
