It belongs to the trigonal crystal system, and the crystal form is often cylindrical, short column, plate, etc., and the geometry is mostly granular or dense block. Transparent to translucent, vitreous luster. The refractive index is 1.76-1.77, the birefringence is 0.008, and the dichroism is strong. Heterogeneous body. Sometimes it has a special optical effect - the star effect. The hardness is 9, and the density is 3.95-4.1 g/cm3. No cleavage, fissure development. Industrial sapphire is a material used in special vehicles as transparent armor, and with the exception of diamonds, sapphire is harder than any other natural material. Sapphire belongs to the trigonal crystal system and has a hexagonal structure. The lattice constants are: a=b=4.758A, c=12.991A Refractive index 1.762-1.770 Birefringence: 0.008- 0.010 Uniaxial crystal negative light, in some cases abnormal biaxial crystal light Luster: bright glass luster to adamantine luster Pleochroism: Colored sapphires have dichroism, generally, dark blue/blue, blue/light blue, blue-green, blue-gray, yellow sapphire has golden/yellow, orange/light yellow, light yellow/ Colorless, wait.

Honing refers to a set of stones (sticks) assembled on the honing head put pressure on the work-Piece along the radial, and through rotating and moving back and forth for precision honing machine. When honing high hardness and toughness materials, the Diamond /CBN Efficiency of honing stone( stick) is 3-75 times higher than that of ordinary abrasive stone, and the honing efficiency of ordinary materials is also improved about 10 times. since Diamond/CBN honing stone (stick) wear is less, the shape retention is better, therefore, the higher honing accuracy and economic effect can be obtained. Diamond honing stick is used to process hard and brittle materials, such as honing high carbon steel, cast iron, cemented, carbide, etc. honing stick mainly used for honing high strength alloy steel, tool steel, stainless steel heat-resistant alloy steel.
