    How to grind sapphire workpieces

    Sapphire consists of Al2O3 and has a Mohs hardness of 9, which is second only to superhard materials in hardness. Due to its superior light transmittance and wear resistance, it is mostly used in the substrate of LED light-emitting components, optical windows, and watch cases of high-end watches and cell phone cameras, etc.The processing process usually requires high precision, fast processing efficiency, low material loss and a clean working environment. Diamond is the hardest and most wear-resistant material in nature, so diamond tools are the best choice for processing sapphire materials.
