近代的龙门鉋床是一种高效率的工具机,但要充份地发挥它的效力,刀具的合理设计却极为重要。倘刀具设计不良,则无论什么新式鉋床都难望获得很好的效果。有些工厂里面对铣刀镗刀和其他特种刀具的制造都很考究,但对鉋刀的设计却往往忽略,这种毛病在中国似乎相当普遍。工业部虬江机器厂在去年对鉋刀工具的改进做了些初步的工作,结果还算满意。在改进工作中,平均工作效率
Modern planer is a high-efficiency machine tool, but to fully play its effectiveness, the rational design of the tool is extremely important. If the tool design is poor, no matter what the new planer is expected to get good results. Some factories face the manufacture of cutter boring tools and other special tools, but the design of planing tools is often neglected. This problem seems quite common in China. In the past year, Qijiang Machinery Factory of the Ministry of Industry made some preliminary work on the improvement of the planer tool, and the result was still satisfactory. In improving the work, the average work efficiency
