在各种类型的磨床上,砂轮与工件之间振动的出现,都致使表面光洁度的恶化,以及砂轮寿命的缩短。在有些情况下,存在着由各种原因激发的强迫振动。而通常出现的振动则具有自激振动的全部特征。振幅随着磨削时间而增长,其频率则决定于机床——砂轮——工件系统的某些固有频率。近年来,好些实验室都对磨削颤振进行了实验和理论性的探索。积累了有关技术参数 In all types of grinding machines, the presence of vibrations between the grinding wheel and the workpiece results in a deterioration of the surface finish as well as shortening the life of the grinding wheel. In some cases, there are forced vibrations that are excited by various causes. The usual vibration has all the characteristics of self-excited vibration. The amplitude increases with grinding time and its frequency depends on some natural frequency of the machine-grinding wheel-workpiece system. In recent years, many laboratories have experimented and theoretically probed the grinding flutter. Accumulated the relevant technical parameters
