Name:Vitrified Diamond Grinding Wheel 4A2
Description:Vitrified diamond grinding wheels are a kind of circular bonded abrasive with through-hole in the center which made of diamond powder and vitrified (ceramic) bond. It is composed of the diamond layer, transition layer, and matrix.
The main components of the vitrified bond: some mineral raw materials and vitrified material with the low melting point, and the composition is more and complex. Its raw materials mainly include 3 parts: Part 1 is plasticity raw materials, such as loess, clay, bentonite, and etc. Part 2 is barren raw materials, such as fluorite, quartz and etc. Part 3 is accelerating melting raw materials, such as borax glass, talc, feldspar, and etc.
Applications:PCD and PCBN tools, tungsten carbide, engineering ceramic
