在毛主席革命路线指引下,为了“开发矿业”,大打矿山之仗,为我国社会主义建设提供更多的矿产资源,我所与湖南煤田勘探二队、勘探一队,共同协作,在原采用的冷压浸渍法和热压法工艺的基础上,1975年开始对无压浸渍法制造钻头和扩孔器的工艺进行了试验研究,并应用这一工艺制造出聚晶钻头、天然表锒钻头、螺旋形聚晶扩孔器和磨料级孕锒钻头,先后在湖南涟源、耒阳、广西融水等地进行生产性试验。效果良好。特别是磨料级孕锒钻头采用无压法制造是在以华主席为首的党中央领导下,一举粉碎“四人帮”的大好形势下试制成功的,并取得良好效果,为人造金刚石钻头制造工艺简便化迈出了可喜的一步。现将该工艺和产品使用效果总结于后。
Under the guidance of Chairman Mao’s revolutionary line, in order to “develop the mining industry,” fight the battle of the mines and provide more mineral resources for the socialist construction in our country. In cooperation with the first exploration team of Hunan Coalfield, Based on the cold-pressure impregnation method and the hot-pressing method, a pilot study on the technology of manufacturing a drill and a reamer without pressure impregnation was carried out in 1975, and a polycrystalline bit, a natural table drill bit , Spiral polycrystalline reamer and abrasive grade pregnant 锒 drill, successively in Hunan Lianyuan, 耒 Yang, Guangxi melt water and other places for productive test. Good effect. In particular, abrasive-grade pregnant women drill bits manufactured by pressureless method were successfully trial-produced under the excellent situation of smashing the “gang of four” under the leadership of the party Central Committee led by Chairman Hua and with good results. The manufacturing process for man-made diamond bits was simplified Took a welcome step. Now the process and product use results summarized later.
