Abrasive hardness measurement methods are more commonly used hand cone, mechanical cone method, Rockwell hardness measurement method and sandblasting assay.
The hardness of the abrasive and its dynamic modulus of elasticity has a corresponding relationship, which is conducive to the audio abrasive measured dynamic elastic modulus of said abrasive tools. In the double disc grindingprocess, if they areinternal grinding workpiece material hardness, generally used in low hardness abrasive; Conversely, the selection of high hardness abrasive.
