摘要
通过实验研究和实际使用,结果发现,刀具经深冷处理后无变形和裂纹,深冷处理提高刀具使用寿命的工艺可广泛在机械加工中推广使用.
Based on experimental research and practical application, the result shows that, after cryogenic treatmeut, neither deforation nor crack are created, and the process, by which cryogenic treatment increase service life of the cutter,could be widely used in machine processing.
