摘　　要：采用宏观检验、微观检验、硬度测试等方法对万能工具磨床用钳口开裂原因进行分析。结果表明,淬火加热温度过高和冷却液浓度偏低是影响磨床钳口淬火开裂的主要原因,并提出了预防措施。The failure of the universal grinder clamps was analyzed by the macroscopic methods, microscopic examination and hardness testing. The results indicate that the primary failure causes are the high quenching heating temperature and the low concentration of liquid coolant. The improvement measures are proposed.
