適用范圍：This International Standard specifies the maximum permissible values of unbalance for various types of grinding wheels in the as-delivered condition, with outside diameter equal to or greater than 125 mm and with a peripheral speed greater than or equal to 16 m/s.It also specifies the method for measuring the unbalance and the practical method for testing whether a grinding wheel is acceptable or not.This International Standard applies to bonded abrasive grinding wheels in the as-delivered condition.This International Standard does not apply to— diamond, cubic boron nitride or natural stone grinding wheels;— centreless control wheels, lapping and disc wheels, ball wheels or glass grinding wheels.NOTES1 The values given refer to the grinding wheel itself, independent of any unbalance which may exist in the balancing arbor or in the means of fastening it to this arbor. These various elements, together with the flanges or hub-flanges, are assumed to be balanced, homogeneous and free from geometrical defects.2 The effects of unbalance are basically— additional stresses on the arbor, the machine and its mounting;— excessive wear of the bearings;— vibration prejudicial to the quality of machining and increased in-ternal stresses in the grinding wheel;— increased operator fatigue.
