金刚石是由具有饱和性和方向性的共价键结合起来的晶体，因此它具有极高的硬度和耐磨性，是目前所知自然界中最硬的物质。主要应用于机械加工、航空航天、切削工具、电子、国防、激光与光学、医疗保健、路面维修、汽车、石材建筑等。

人造大单晶金刚石主要用于：切削工具，修整工具等；
郑州锐捷有限公司提供门类齐全的单晶条形和多边形产品，以及人造大单晶金刚石以满足各种修整工具（包括单点、片状、旋转和滚轮修整器等）、特殊切削刀具以及压痕器的应用需求。该系列产品是在单晶金刚石原坯的基础上深加工而成，所有的表面均被切割至特定尺寸。

单晶金刚石的优势：

切削时不易黏刀及产生积屑瘤，加工表面质量好，加工有色金属时，表面粗糙度可达Rz0.1～0.05μm。金刚石还能有效地加工非铁金属材料和非金属材料，如铜、铝等有色金属及其合金、陶瓷、未烧结 硬质合金 、各种纤维和颗粒加强复合材料、塑料、橡胶、石墨、玻璃和各种耐磨木材(尤其是实心木和胶合板、MDF等复合材料)。

1、天然钻石(ND)刀具：天然钻石(金刚石)硬度达HV9000-10000，是自然界中最硬的物质。

金刚石大单晶刀具适用范围：

五金车件、汽车配件、表面处理、工艺制品、精雕、铜料批花、手机金属按键、手机外壳、数码外壳、金属高光批花、钟表表面、子钉、表壳内映刀、名牌、标牌高光批花、车CD纹、车七彩纹、车太阳纹、铝制品高光、电器外壳批花、电器面板、车载面板、电脑周边设备、电脑透明机箱、亚克力抛光、精车加工等。

• PRODUCT DETAILS:

Big size synthetic diamond (BSSD) means the high quality grade Diamond Grits which the diameter is from 0.8mm to 4.2mm. Compared with traditional synthetic diamond, BSSD has the characteristics of: Bigger grits diameter, higher quality grade, higher TI/TTI data, more transparent, better crystal shape, more pure color. 

Big size synthetic diamond can be pided into six quality grades:

SMD691: Perfect crystal color, regular shape, good transparency, high strength and great thermal stability. Suitable for making cutting tools. Also can be used as jewelry and replace natural diamond. 

SMD690: Consistent crystal color, regular shape, good transparency, high strength and high thermal stability. Suitable for making tools for sawing all kinds of hard stone &concrete, for geological drills. It also can be used as jewelry. 

SMD680: Complete crystal shape, perfect cubic octahedron, good diaphaneity, high impact strength and thermal stability. Suitable for high grade cutting, drilling and grinding tools.
 
SMD660: Complete crystal shape with full surface, good diaphaneity and low impurity, high strength. Suitable for circular saws, frame-saw and geological broaches.
 
SMD640: Comparatively regular crystal shape, high mechanic strength, belonging to middle quality grade among them, containing more regular crystal. Suitable for grinding and free-cutting tools, grinding wheels which work with medium load .
 
SMD620: Comparatively regular crystal shape, sharp edges, low strength, belong to low quality grade among them. Suitable for grinding tools and wheels that work with low load.
