Marble/Granite square A square marble fixture, has the function of parallelism and perpendicularity checking, is the more common type, different times, which is not the point of inspection and processing tools, they are mainly measured, tested or manufactured stone to build a parallel effect to achieve perfect parallelism and perpendicularity of the workpiece. Because of this, they are among the many stone artifacts, there are some professional effects. Marble square foot is parallel to the vertical box combination used for testing at right angles, suitable for high-precision machinery and equipment inspection and not perpendicularity between machine check. Marble square is to use natural marble processing, and marble are recrystallized limestone, mostly CaCO3. Limestone at high temperature under high pressure soft and mineral changes again in the crystallization of marble. Marble is original rock of the crust after high temperature and pressure within the Earth's crust is formed of metamorphic rocks. Role of crustal stress of the qualitative changes in the rock, that is the original rock structures, construction and mineral content change through qualitative change the formation of the new rock known as metamorphic rocks; the marble is composed of calcite, limestone, dolomite and serpentine form. Its main component calcium carbonate, accounted for more than 50% because of marble are impurities and calcium carbonate, carbon dioxide in the atmosphere, carbon, the role of water vapor are also prone to weathering and erosion, and make the surface very quickly lose its lustre. Marble mainly for processing into various shapes, plates and so on; so the marble square with no distortion high hardness wear resistance strong, abrasion-resistant, high temperature and other characteristics of marble square plane precision, vertical standard for GB6092-85.
Marble square Physical stability of tissue carefully can't afford to hit the surface of grain shedding burrs do not affect the Planar accuracy, can guarantee the long-term deformation, low linear expansion coefficient, suitable for industrial production of the vertical measurement.
