The hardness of the abrasive

its dynamic modulus of elasticity has a corresponding relationship, which is conducive to the audio abrasive measured  flap disc dynamic elastic modulus of said abrasive tools. In the grinding process, if they are grinding workpiece material hardness, generally used in low hardness abrasive; Conversely, the selection of high hardness abrasive.
Grinding of crude into tight, medium and loose categories. Each category can be further subdivided and number, with quick change disc  the numbers to differentiate between organizations. Abrasives organization number greater share of the abrasive grinding smaller volume percentage, the wider the gap between the grains, which means that more loose tissue. On the contrary, the smaller the number of organizations expressed more tightly organized. Loose organization is not easy to use abrasive passivation less heat during grinding, the workpiece can reduce heat deformation and burns. Tight ceramic belt  organization abrasive grit easy to fall off, helps maintain the abrasive geometry. Abrasives organization only in the manufacture of abrasive formulations are controlled by, generally do not make dete
