俗话说“钳工怕眼,车工怕杆”,细长轴加工确实比较困难,加工出的工件容易发生弯曲、竹节形、多棱、锥度等等问题,达不到质量要求。一般多采用高速钢车刀低速切削,生产效率也很低。我厂史洪志老师傅等经过了多年的研究改进,摸索出一套快速车削细长轴的方法,采用硬质合金车刀,车速由原来的10米/分提高到56～112米/分。 As the saying goes, “fitter afraid of the eye, car workers fear of bar,” slender shaft processing is indeed more difficult, the processed parts prone to bending, bamboo shape, polygons, taper and so on, not up to quality requirements. Generally use low-speed high-speed steel turning tool cutting, production efficiency is very low. After years of research and improvement, Mr. Shi Hongzhi, the master of our factory, worked out a set of methods for fast turning slender shafts. Carbide turning tools were used to increase the speed from 10 m / min to 56-112 m / min.
