钎焊的硬质合金刀具被广泛地应用在各种金属的切削加工中。对于硬质合金刀具钎焊后的性能变化,现有的大多数资料均认为是性能下降。但究竟是哪些参数发生了变化?变化了多少?以及对刀具的切削性能有何影响等问题都缺乏确切的数据和完整的资料。放就硬质合金刀具经钎焊后硬度、钎焊裂纹的观察情况、钎焊刀具与机夹同种刀具耐磨损性能比较等几方面进行探讨。 Brazed carbide cutting tools are widely used in various metal cutting. For brazing carbide tool performance changes, most of the existing data are considered to be performance degradation. But exactly what parameters have changed? How much has changed? And the impact on the cutting tool performance and other issues are the lack of exact data and complete information. Put carbide cutting tool after brazing hardness, brazing cracks observed, brazing tools and clip the same type of tool wear resistance comparison of several aspects to be explored.
