喷射钻是一种先进的深孔钻,效率为普通钻头的5～10倍,甚至更高,精度和光洁度也很好。我厂自81年在葛洲坝发电机组 M170联轴螺杆上快速钻成φ24.6,深900毫米深孔以来,经常有人来了解情况。由于钻头几何形状基本上是仿造瑞典的,杂志上已有很多介绍,这里仅对我厂喷射钻装置和工艺要点作一简要介绍。 Jet drills are advanced deep-hole drills with 5 to 10 times the efficiency of normal drills and even higher precision and finish. Since 81 years in our factory in Gezhouba M170 rapid coupling screw shaft drilled into φ24.6 deep 900 mm deep hole, often someone to understand the situation. As the bit geometry is essentially imitation of Sweden, the magazine has a lot of introduction, here only my factory jet drilling device and process points for a brief introduction.
