JB57-1600·7-9压力机副螺纹杆加工过程中金属刀具的选择特点及加工工艺设计

The Feature of the Cutting Rool in the Working Process of JB57-1600·7-9 Press Machine's Threaded Rod and Technological Design

机械加工中的对金属材料的加工的刀具的选择,是由其加工的工件的工艺性决定的。刀具性能和质量,都直接影响切削加工效率、加工精度和表面质量。刀具的改进和发展,往往起到促进加工工艺和机床设备发展的作用。而刀具的改进提高是由其加工的对象决定的,合理地选择刀具加工参数才能保证加工工件的工艺技术要求。

The choice of cutting tools for machining of metal material in machining process is determined by the processing of the work piece. The tool performance and quality of the pros and cons, both directly affect the machining efficiency, machining precision and surface quality. The improvement and development of cutting tools often play a role in promoting the development of processing technology and machine tools. The improvement of cutting tool is determined by the object of its processing, and it is reasonable to choose the parameters of cutting tool to ensure the processing technology.
