Determination of the balance quality of diamond grinding wheel

The so-called diamond grinding wheel balance, as defined, is a procedure to detect and, if necessary, correct the mass distribution of the grinding wheel, to ensure that the vibrations and bearing forces generated during operation at the operating speed are within the specified range. This definition clearly states. When the diamond wheel is balanced, it is not required to achieve complete balance, but a certain amount of remaining is allowed. At present, the balance quality of the diamond grinding wheel is generally determined by reference to the mother's 01940 specification (the judgment standard of the balance state of the rotating rigid rotor), and the ISO recommended standard (balance accuracy of the rotating rigid rotor) based on this. The ordinate is the allowable eccentricity e, also known as the allowable unbalance rate, that is, the allowable unbalance per unit weight of the grinding wheel. It can usually be used on the drawing to measure the balance of a grinding wheel or the accuracy of the dynamic balancing machine. The size of the unbalance of the diamond grinding wheel can also be expressed on the drawing with the allowable unbalanced moment. It is the product of the weight M of the diamond grinding wheel and the allowable eccentricity e, in grams and millimeters.

Normally, when correcting and balancing the grinding wheel, the allowable unbalance torque is better, because it can be directly displayed by the balancing machine.

Since the cylindrical or cylindrical diamond-like grinding wheel has both static and even unbalance, the main hazard is the latter, so the diamond grinding wheel must be added (or subtracted) to each of the two calibration planes. Go) a balance weight. The diamond grinding wheel is balanced, so it is called dynamic balance, also called double-sided balance.
