180*6*22mm metal grinding disc with diameters greater than 125 mm should be balanced so that the center of gravity of the wheel coincides with its axis of rotation.
The unbalanced grinding wheel will produce a vibration when it rotates at high speed, the quality of color sound processing and the precision of machine tool, and will cause machine damage and 180*6*22mm metal grinding disc fragmentation when it is serious.
Therefore, the balance must be balanced before installing the grinding wheel. The balance of the grinding wheel has two kinds: static balance and dynamic balance. In this case, only static balancing is required, but dynamic balancing is required in high-speed mushroom grinding (speed greater than 50m/s) and high-profile grinding. The following figure shows the static balancing device of the grinding wheel. Stop it.
The balancing wheel can be stationary in any position. If 180*6*22mm metal grinding disc is unbalanced, the heavier part of the wheel always goes below. The balancing block can be moved to balance. Cracks must be checked before the balanced grinding wheel is installed on the main shaft of the machine tool. Cracks in the grinding wheel are absolutely forbidden to use. Set the clearance to prevent the expansion of the spindle from expanding.
The method of balancing grinding wheel is to install several balancing blocks in the annular groove of the flange of 180*6*22mm metal grinding disc and make the center of gravity of the grinding wheel coincide with its rotating axis by adjusting the position of the balancing blocks.
