Marble square box

The marble cube has a dense organizational structure, a smooth and wear-resistant surface, and a small roughness value. After long-term aging, the internal stress of the marble dissipates, making the material stable and non-deformable. Since marble is a non-metallic material, it does not exhibit magnetic response and does not undergo plastic deformation.

The marble square boxes are made of Jinan Green, featuring a black luster in granite. The structure is dense, with uniform texture and good stability, high strength, and hardness. The work surface is processed using scraping or precision grinding techniques, suitable for measuring the straightness and perpendicularity of workpieces as well as equipment installation.

Applications for Marble Square Boxes

Marble square boxes are primarily used for precise measurement of the flatness and perpendicularity of mechanical parts, workpieces, machine tool workbenches, guides, and more. Due to their excellent stability, marble square boxes can operate normally in a wide range of working environments.

Marble square box specifications

Marble square boxes are manually polished according to the JB/T7975-1999 standard.
