应用铜液浸渍镶焊硬质合金钻头的方法,在“地质与勘探”1958年第11期发表以后,先后有四十多个单位来函学习推广这一经验,这给我们鼓励很大.经过大搞技术革新运动,在工人同志与技术人员通力合作下,又将这项先进经验做了进一步的改进,同时在生产中又摸索了一些经验,生产效率在原有基础上又大大提高了一步,每班浸渍91公厘及100公厘8个刃硬质合金钻头达到1300个到1500个,生产效率提高四倍半以上.现仅在原有基础上,将我们所进行的改进做如下补充介绍:
Application of copper immersion carbide insert drill method, “Geology and Exploration ” in 1958 after the publication of the 11th, there have been more than 40 units to learn from this letter to promote this experience, which gives us great encouragement. Through vigorous technical innovation campaigns, with the concerted efforts of workers and technicians, this advanced experience has been further improved. In the meantime, some experience has been explored in the course of production and the efficiency of production has been greatly increased on the basis of the original ones , Each class is impregnated with 91 mm and 100 mm 8 blade carbide drill 1300 to 1500, more than four and a half times more efficient production.Only on the original basis, we will make the following improvements introduced by the introduction :
