几种牌号刀具对Inconel 625切削性能的对比研究

Comparative study on the cutting performance of Inconel 625 with different tools

通过研究对比几种常用牌号刀具(YT类硬质合金、YG类硬质合金、高钴高速钢、PVD涂层硬质合金)在车削镍基高温合金Inconel 625时的切削性能,分析了不同刀具的寿命及对试件表面质量的影响,明确了适用的刀具和合理的切削用量及切削速度。分析认为,性能优异的PVD涂层刀具在选择了合适的进给量之后,完全能够满足Inconel 625的切削加工,相对于其他常用刀具,无论在生产效率还是产品质量方面,都有了很大的提升,并且节约了生产成本。

Through research and comparing the cutting performance of four different tools （ YT carbide cutting tool, YG carbide cutting tool, high - cobalt high speed steel and PVD coated carbide cutting tool） with In- cone1625. The tool life and workpiece surface quality with different tools are analyzed. And then, the applicable tool, cutting parameter and cutting speed are cleared. It is found that PVD coated carbide cutting tool with excellent properties is competent for the demand of cutting Inconel 625 when selecting the appropriate feed. Compared to other tools, the efficiency of the cutting process is increased, the sur- face quality is improved and the production cost is reduced.
