Comparative experimental study on edge machining of carbide end milling cutter with different tool passivation methods

  • 摘要: 为改善刀具性能、提升加工质量,采用旋转磨粒流对刀具钝化。通过对比立式旋转钝化法和旋转磨粒流钝化法钝化硬质合金立铣刀的效果,研究刀具刃口变化规律。试验结果表明:未钝化的刀具刃口半径值最小,且存在很多缺陷,刃型呈尖锐形;立式旋转钝化法得到的刃口半径值变化较小,但刀具刃口缺陷仍然存在,刃型呈不均匀的钝圆形;旋转磨粒流钝化法处理后的刃口半径值变化最大,去除了部分刃口缺陷,刃型呈均匀的钝圆形。旋转磨粒流钝化法不仅可以更好地去除刀具刃口的表面缺陷,同时有着更高的钝化效率以及刃口半径变化率,可以显著提高刀具性能,降低刀具磨损并改善加工质量。
