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。Abstract: A tool passivation method called the rotating abrasive flow passivation method is proposed as a means to improve tool performance and processing quality. Experiments were conducted to compare the passivation of a carbide end milling cutter by vertical rotating passivation and rotating abrasive flow passivation, revealing the changing law of the tool edge. The results show that the original tool's edge has the smallest radius, characterized by a sharp edge with numerous defects. After vertical rotating passivation, there is slight change in the edge, but defects persist, and the blade shape remains unevenly blunt and circular. In contrast, As the edge after rotating abrasive flow passivation shows the most significant radius change, with some edge defects removed, resulting in a uniformly blunt circular edge shape. The rotating abrasive flow passivation method can not only eliminates edge defects but also presents higher passivation efficiency and a greater rate of change in the cutting edge radius. This method can significantly enhance tool performance, reduce tool wear, and improve machining quality.
