Marble square Is a professional measuring tools, referred to as square, also called on some occasions on foot, used to detect vertical and perpendicular to the relative position of the workpiece the workpiece, sometimes also underlined. Granite square suitable for vertical degree of testing. Plane precision standard GB6092-85, vertical-standard GB6092-85. To reduce weight and facilitate the process and increase the weight hole. Tolerance is on the side of 0.02.

Marble square Mainly used for workpieces of flatness, squareness, straightness measurement. Main mineral elements escape the stone marble square, plagioclase, a small amount of olivine, biotite, and trace amounts of magnetite, black color, precise structure, after millions of years of aging, the texture is uniform, good stability, high strength, high hardness, able to remain under heavy load and high precision. Suitable for industrial production and laboratory measurements.

Marble square features:

1, Marble square Rock long natural aging, organizational structure, uniform, linear expansion coefficient is tiny, internal stress disappears completely, without distortion, and high accuracy.

2, Marble square High rigidity, high hardness, wear resistance strong.

3, Marble square Acid, alkaline fluid erosion, will not rust, do not oiled, not easily stick dust, maintenance, maintenance convenient and simple, long service life.

4, Marble square Not a scratch, not subject to constant temperature conditions prevent, can keep at room temperature measurement accuracy.
