balance scaffold made of high quality material for the balance shafts, the heat treatment and high precision machining and assembly therefore precision, stable performance is an ideal machine tool accessories. larger than 125mm diameter wheel must be balanced so that its center of gravity coincides with the axis of rotation of the wheel.Unbalanced wheel at high rotational vibration occurs, affecting the processing quality and precision machine tools, it can also cause serious damage to the machine and wheel fragmentation. Caused by an imbalance of the original storm largely uneven density portions of the wheel, asymmetric geometry and installation eccentricity. Therefore, before installing the wheel must be balanced, the balance wheel static balance and dynamic balance are two kinds. Under normal circumstances, just as static balance, but in high-speed grinding (speeds greater than 50m / s) and high speed grinding, it must be balanced.When the balance wheel mounted on the mandrel balance, then install the kind of wheel axle flat onto the balance wheel balance rail bracket, the wheel will swing back and forth, until the swing stops. If the grinding wheel imbalance, it always goes below the heavier portion. In this case the position of the movable balancing blocks to reach equilibrium.
