    description

    Granite machine parts use for accurate measurement and provide a flat and stable environment for inspection manufacturing. They are free temperature distortion and offer an exceptionally sturdy measuring environment due to their thickness and weight.

    Measuring on uneven surface can give incorrect or inconsistent inspection results, using a granite plate can help eliminate this problem.
