Background

China is a large country for producing industrial synthetic diamonds, the yield is the first world, and the industrial synthetic diamonds are widely used for manufacturing probes and grinding tools for drilling because of high hardness. The yellow cultivated diamond is a high-yield product in industrial synthetic diamonds, mainly has the size of 1-2 mm, and has the characteristics of small size, high hardness, irregular shape, light weight, high yield and the like.

The yellow cultivated diamond has wide application, wherein, the yellow cultivated diamond product with regular crystal form, lower strength and larger brittleness is used for grinding with lighter load such as a grinding wheel; the diamond with regular crystal form, high mechanical strength, medium grade and high proportion of complete crystal form is used for medium load cutting of grinding tools, free cutting tools, grinding wheels and the like; yellow cultivated diamond products with complete crystal forms, higher impact strength and better thermal stability are used for marble, granite, nonferrous metals and various engineering cutting tools; the yellow cultivated diamond product with good consistency of crystal color, regular crystal form, good transparency, high strength and better thermal stability is used for cutting refractory materials, various hard stones and concrete and various geological engineering drill bits; the yellow cultivated diamond product has good consistency of crystal color, regular crystal form, good transparency, high strength and good thermal stability, and is used for cutting ceramics, various hard stones and reinforced concrete and various geological engineering drill bits; the yellow cultivated diamond product with complete crystal, transparency, high impact toughness and high heat stability is used as high strength sawing tool, correcting tool, drill bit, etc. under harsh condition.
