摘要
钽钨合金零件的传统制造方法为冲压或摆动碾压成型,其加工精度较低,需进行切削加工,以满足工业对钽钨合金零件的制造精度需求。钽钨合金属于难切削材料,尤其是高钨含量钽钨合金的切削性更差,实现其精密切削加工的难度较大。针对Ta-12W某零件,基于钽钨合金的性能分析,借鉴相关难切削材料加工工艺的实践经验,从刀具设计、装夹定位方法和切削参数选择与优化等方面进行了切削工艺试验,较为经济地实现了该合金零件的精密切削加工,满足工程应用中高钨含量钽钨合金零件的精密切削加工需求。
In traditional machining methods, the products made of Ta-W Alloys were manufactured by rolling grinding or stamping.The precision was too low.The cutting process was applied to improve its precision and to satisfy the demands in the fields of national diffwult to cut the Ta-W Alloys,especially the alloys with high defense and chemical industry.But it＇s very wolfram content.By analyzing the Ta-W Alloys＇properties and referring to the related materials＇cutting process ,the new process of cutting the Ta- 12W alloy was studied by designing cutter and optimizing the process parameters.The results show that it＇s economical to cut the alloy with high precision during the cutting process.The new process is being applied to cut the Ta-W Alloys with high wolfram content in engineering application.
