The paper presents the results of tool life calculations and testing of threading profiled tools with brazed hardmetal inserts upon surface plasma modification. The tool life of such inserts has been found to be 2.15–2.5 times (by the criteria of optimal and equal wear) that of unmodified ones. Upon re-sharpening of tools, their life becomes shorter due to a decrease in hardness of cutting edges, but is still much longer than that of tools with unmodified inserts.

通过对刀片表面进行等离子改性来增加硬质合金螺纹刀具的刀具寿命

本文介绍了工具寿命计算的结果,以及在对等离子进行表面改性后,对带有硬质合金刀片的螺纹成型工具进行测试的结果。已经发现,这种刀片的刀具寿命是未改性刀片的2.15-2.5倍(以最佳和均等磨损的标准为基准)。在重新锐化刀具时,由于切削刃硬度的降低,它们的寿命会缩短,但仍比未修饰刀片的刀具要长得多。
