金刚石是一种非常坚硬的物质,它具有特殊的物理性能,硬度及抗压强度高,耐磨性能好。用金刚石加工出来的工具,被广泛应用到地质钻探、机械工业、光学玻璃加工业、工艺雕刻业以及医疗器械领域中。五十年代就有金刚石和金刚砂应用于口腔科的文献报导,近年来应用就更为广泛了。 Diamond is a very hard material, it has a special physical properties, hardness and compressive strength, good wear resistance. Tools machined from diamond are widely used in the fields of geological drilling, mechanical engineering, optical glass processing, process carving and medical devices. In the fifties there were reports of the use of diamond and emery in the dentistry, which have become more widespread in recent years.
