金刚石,一般人称金刚钻,又叫钻石.一提起它,人们总会联想到那是一种瑰丽多彩,光耀灿烂,可以用来做装饰的名贵宝石.其实,现在我们说它的名贵,不仅是因为可以做装饰品,更重要的是它应用在近代工业方面的价值很大. 工业上所以珍视金刚石,因为它具有高于一切物质的硬度和难以磨灭的特性.应用金刚石的工业部门不胜枚举.将金刚石制成地质钻探锥冠,可以钻透地壳最硬岩层,它在金属矿床与石油开采钻进中效率远较硬质合金钻头高数倍至数十倍,特别在岩心选样作业中效果最好.用金刚石修整砂
Diamond, commonly known as diamond drill, also known as diamond. When you mention it, people will always think that it is a magnificent, colorful, precious gem that can be used for decoration. In fact, now we say it’s expensive, not only because It can be used as an ornament, and more importantly, it is of great value in modern industrial applications. Industrially, it cherishes diamonds because it has higher hardness and indelible characteristics than any material. The industrial sectors that apply diamonds are numerous. The diamond is made into a geological drilling cone crown, which can drill through the hardest rock layer of the earth crust. It is several times more efficient than cemented carbide drill bits in metal ore drilling and oil drilling. It is especially effective in core sampling operations. Best. Dressing sand with diamond
