摘要
介绍了单晶金刚石尖刀的几何参数设计、原材料选择、晶体定向、切割、开坯、装卡、粗磨、精磨和抛光等制备工艺,分析了晶体定向、装卡和研磨等工艺机理,并对制备的金刚石尖刀的刃口锋利度、圆弧半径以及整体状况进行了SEM检测。最后,对我国单晶金刚石尖刀制备技术的发展进行了评述与展望。
The preparation technologies of monocrystal diamond pointed cutters, including design of geometry parameters, selection of material, crystal orientation, incision, sharping, clamping, coarse grinding, finishing grinding and polishing are introduced. The mechanisms of crystal orientation, clamping and finishing grinding are analyzed. And the edge sharpness, edge radius and overall situation of prepared diamond pointed cutter are detected with SEM. Finally, the development of preparation technology of monocrystal diamond pointed cutters in China is commented and prospected.
