说明:该直径喷射钻原由西安847厂与徐州机械研究所于74年共同试制成功,钻头体为机械研究所精密铸造而成。目前,该喷射钻已在徐州机床厂试用。喷射钻(喷吸钻)是一种内排屑硬质合金深孔钻,正常情况下,切削速变可达80米/分,走刀量可达150毫米/分,生产效率比普通麻花钻高5倍以上。加工孔径偏差小于0.05毫米光
Description: The diameter of the original jet drill by the Xi’an 847 Plant and Xuzhou Institute of Machinery jointly trial production in 74 years, the drill body for precision casting machinery Institute made. At present, the jet has been piloted in Xuzhou Machine Tool Plant. Jet Drill (Spray Drill) is a kind of internal carbide chip deep hole drilling, under normal circumstances, the cutting speed change up to 80 m / min, take the amount of up to 150 mm / min, the production efficiency than ordinary twist drill 5 times more high. Deviation of processing aperture less than 0.05 mm light
