Constantly changing state of grinding wheel face

The grinding process, because the wear of wheel itself, constantly changing state of wheel face. As the grinding time, the grinding wheel cutting capacity decreased, various grinding defects continue to appear, the grinding process can not be continued. At  abrasive grinding , you must trim wheel, grinding back to normal state. Between the two dressing grinding wheel grinding time is called the real life of the wheel. Affecting the life of the grinding wheel grinding the important factors,  Diamond blade  for forming grinding particularly important.
Determination wheel life:
Generally worn under the wheel face various phenomena arising through observation and tests carried out wheel wear  Synthetic diamond  arising after grinding are: self-excited vibration generated during grinding, the surface appears regeneration chatter; grinding noise increases; surface grinding burn occurs; grinding force a sharp increase or decrease; precision grinding down; grinding surface roughness increases.
