Granite Square Foot

Granite square rulers are primarily used to inspect the flatness of parts. Granite measuring instruments are fundamental tools for industrial inspection, suitable for verifying instruments, precision tools, and mechanical components, as well as for high-precision measurements.

Granite Cubic Inch Material: Primarily composed of the main minerals in granite, including augite, plagioclase, a small amount of olivine, biotite, and trace amounts of magnetite, with a black color. The structure is dense, having undergone billions of years of aging, resulting in a uniform texture and good stability. It boasts high strength and hardness, maintaining high precision under heavy loads. Suitable for industrial production and laboratory measurement work.

Characteristics and Advantages of Granite Cubic Blocks:

1.花岗石平板 has a dense organizational structure, smooth and wear-resistant surface, and small roughness values.

2. Granite, after long-term aging, the internal stresses dissipate, resulting in stable material properties and no deformation.

3. Acid, alkali, corrosion, and magnetic resistance.

4. Resistant to dampness and rust, easy to use and maintain.

5. Low coefficient of linear expansion, minimally affected by temperature.

Granite square rulers are precision tools crafted from high-quality marble through a combination of machine and manual processing. They feature a smooth surface and high hardness, primarily used in factories for checking the vertical alignment of various machinery and instruments. Made of rock, they do not rust like steel in humid environments, corrode in acidic or alkaline conditions, or become magnetized in strong magnetic fields. Moreover, rocks are harder and more wear-resistant, maintaining their shape. Even upon impact, they may only form a small indentation rather than a protrusion on the surface; however, excessive indentations can affect usability. Since marble is not completely free of impurities, it may lose its luster in the atmosphere, affecting aesthetics only, not its functionality.

To ensure the accuracy and prolong the lifespan of the marble ruler, daily maintenance is crucial. Although it won't deform upon impact from hard objects, it can create small dents that, upon frequent collisions, can accumulate into multiple dents, affecting its usability. Therefore, be gentle during use to avoid excessive dents, as they can make the surface look like the moon's, unattractive and impractical. If not in use for an extended period, apply a dedicated lubricant to the surface; if unavailable, substitute with edible oils like peanut or olive oil. Before next use, simply wipe it with a clean cloth. No matter how careful you are, the surface may still get dirty. In such cases, it's best to gently wipe it with lemon juice or vinegar. Avoid using soap as it can dull the surface.

If the granite cube is not too severely damaged, it can generally be restored to its original smooth surface and maintain accuracy through simple procedures such as sanding and polishing. High-quality measuring tools are a must-have for every industrial site.
