用普通黄色人造金刚石制造电铸钻头是可行的,但用含硼黑色导电人造金刚石制造电铸钻头,国内资料很少.我公司生产的人造金刚石主要是黑金刚石,能不能用它来制造电铸钻头与扩孔器,是我们迫切需要解决的课题.它对扩大黑金刚石的应用,具有现实意义. 我们从1979年底开始这方面的研究工作.两年多来,600多个不同规格、不同用途的钻头和 It is feasible to make electroformed drill bit with ordinary yellow synthetic diamond, but electroplated drill bit made of boron-containing black conductive synthetic diamond has very few domestic materials. The synthetic diamond produced by our company is mainly black diamond, can it be used to make electroforming Bit and reamer, is an urgent problem we need to solve, it is of great practical significance to expand the application of black diamond.We started the research in this area from the end of 1979. Over two years, more than 600 different specifications and different uses Drill bit and
