Excellent characteristics of single crystal diamond meet the precision

 Carbon atoms, a single diamond crystal, the crystal structure of the highest density of metal atom such as axial face-centered cubic crystal. Diamond crystal connected between the carbon atoms  grinding cup wheels bond to sp3 hybridized covalent bond, with a strong binding force, stability and direction. The unique crystal structure of diamond in nature it has the highest hardness, stiffness, refractive index and thermal conductivity, and high wear resistance, corrosion resistance and chemical stability.
Excellent characteristics of single crystal diamond meet the precision and ultra-precision cutting tool material for most of the requirements and is ideal for precision cutting tool materials. Diamond without internal grain boundaries uniform crystal structure so that the tool cutting edge can theoretically reach the atomic level flatness and sharpness, cut thin cutting ability, high precision, cutting force is small; their high hardness and good wear resistance resistance, corrosion resistance and diamomd core drill bits  chemical stability can ensure that the tool has a long life, so that it can continue for a long time of cutting, the tool wear can be reduced because of the precision of the parts; its high thermal conductivity can be reduced and the cutting temperature parts thermal deformation.
Single crystal diamond tool in the machining field has an important position, is widely used as a mirror, missiles and rockets navigation gyro, computer hard disk substrate accelerator electron gun, such as ultra precision mirror of parts. Can also be used in the manufacture of single crystal diamond eye, brain surgeon's scalpel, thin slicing knives and  4 inch saw blades other bio-medical tools. In addition, single-crystal diamond tool in civilian products processing applications are becoming increasingly widespread, from watch parts, aluminum pistons, jewelry and other processing to pens, high-gloss mirror decorative signs and non-ferrous metal parts processing, its application has entered the machining a variety of areas.
