刀具是金属切削加工的重要工具之一。它对发挥机床性能、提高生产率、保证加工质量、降低加工成本都有很大作用。特别是新型刀具的出现,常常把劳动生产率和加工质量提高到一个新的水平,同时也促进机床的相应改革和发展。根据国内外机械工业发展形势和刀具的发展动向,综合分析了大直径刀盘、阶梯铣削和滚切刀具的特点,我们设计了自滚切端铣刀,进行了初步试验,效果良好。
Tool is one of the important tools of metal cutting. It plays a great role in exerting the performance of machine tools, increasing the productivity, ensuring the processing quality and reducing the processing cost. In particular, the emergence of new tools, often to the productivity and processing quality to a new level, but also to promote the corresponding machine tool reform and development. According to the development situation of mechanical industry at home and abroad and the development trend of knives, the characteristics of large-diameter cutter, step milling and hobbing cutter are analyzed comprehensively. We designed the self-rolling end mill and carried out the preliminary test with good results.
