Diamond wire loop cutting machine

Diamond wire loop cutting machine What is diamond wire loop saw? The diamond wire loop is a flexible cutting tool that consolidates diamond on the annular steel wire substrate. It moves in one direction during cutting, and the cutting line speed is 40-60 m/s. The diamond wire loop can realize various precise and efficient cutting, such as Cutting of silicon crystal, sapphire, precious wood, graphite, magnetic materials, etc. the wirecutter The traditional reciprocating cutting requires constant reversing, so the line speed is limited [...]

Application of diamond wire loop in graphite industry

Application of diamond wire loop in graphite industry At present, the graphite industry has been developing rapidly, so what is graphite? Graphite is an allotrope of carbon. It is a gray-black, opaque solid with stable chemical properties, corrosion resistance, and is not easy to react with chemicals such as acids and alkalis. Combustion in oxygen produces carbon dioxide, which can be oxidized by strong oxidants such as concentrated nitric acid and potassium permanganate. Can be used as anti-wear agent, lubricant, high-purity graphite is [...]
