本刊1986年第11期发表了《深孔麻花钻的结构与应用》一文,该文所介绍的钻头系江西量具刃具厂生产,据用户反映,钻头使用效果良好.例如,上海汽轮机厂为原子电站加工钢号为美WR26的螺栓孔,普通麻花钻难以加工,新型深孔麻花钻则能满足加工要求,钻通300mm的孔,原加工时间为50分钟,而用新型深孔钻后仅需8分钟;上海新中动力机厂在镗床上
This issue of 1986 No. 11 published a “Deep-hole twist drill structure and application,” a article, introduced in this article Jiangxi Measuring Tool and Cutting Tool Factory production, according to user feedback, the drill with good results.For example, the Shanghai Steam Turbine Factory as an atom Power station steel for the United States WR26 bolt hole, the common twist drill difficult processing, the new deep-twist drill can meet the processing requirements, through the hole 300mm, the original processing time of 50 minutes, and with the new deep-hole drilling only 8 minutes; Shanghai New Power Plant in the boring machine
