Diamond wire consists of a piano wire core with affixed diamond grains. Diamond tools are used to slice all kinds of materials, such as silicon and sapphire. Using this diamond wire improves productivity compared to methods based on loose grain systems by improving machining efficiency and providing consistent machining precision. Since slurry isn’t required, diamond wire lets companies make significant reductions to their environmental impact.

Line up
