Performance Analysis Of Vitrified Grinding Wheels
⑴ Due to its excellent properties of ceramic materials, such as high hardness, highabrasion resistance, high temperature resistance, corrosion resistance, high stiffness to weight ratio, low density and high chemical inertness, which is widely used inscience and industry.
⑵ High temperature superconducting single crystals are widely used, thin film substrate, laser components, the use of these new materials, due to the brittle, easy to crack when processing, often accompanied by extensive machining problems.
⑶ Diamond is the hardest material found in nature, with wheels made of it resolved the glass, ceramic and other hard material machining problems. For the development of new projects such as Silicon nitride ceramic, resin or metal bond diamondgrinding wheels for grinding, prone to bond to grain pullout not enough, wear increases; or the toughness of bond is too large, less gas holes in wheel, grinding forces down, grinding hard to trim the insensitive, the entire grinding more difficult.
⑷ Quality vitrified ceramic or vitreous, binders, rigid, resistant to high temperatures, grinding suitable for precision trimming, not cutter. Adhesion and vitrified abrasive, and edges to keep good performance, high-precision grinding.
⑸ Vitrified bond of diamond wheel in the manufacturing process can be adjustedfor hardness and porosity, is conducive to the improvement of grinding performance by proper Proportioning and production control, no distortion, this is the reason for high Machining accuracy of grinding wheel.
