Unbalanced grinding wheel in the high-speed rotation will produce vibration, affecting the quality of processing and machine tool accuracy, serious will cause the wheel fracture, endangering the safety of people and equipment. The main reason for the imbalance caused by uneven density of all parts of the wheel, geometric asymmetry and installation eccentricity and so on.
Therefore, the grinding wheel must be balanced before installation. There are two kinds of static and dynamic balance: - Static balance only; In the high-speed grinding and high-precision grinding, it must be balanced. For large-diameter grinding wheel, after the use of a period of time, due to grinding wheel wear, there may be unbalanced, need to balance again.
