以ＧＨ４１６９高温合金为主要研究对象，论述了高温合金的磨削特征。由于高温合金的难磨性以及磨削时砂轮表面存在严重的粘附物，因而使磨削力和磨削温度显著增高，磨削比非常低。
Taking GH4169 superalloy as the main research object, the grinding characteristics of superalloy are discussed. Due to the high wear resistance of the superalloys and the presence of severe adherents on the wheel surface during grinding, the grinding force and grinding temperature are significantly increased and the grinding ratio is very low.
