In the field of precision measurement, granite measuring tables stand out prominently among numerous measurement platforms, winning wide recognition from global industries. Their exceptional performance stems from two core strengths: superior material properties and thoughtfully engineered structural features—key factors that make them the top choice for businesses seeking reliable precision measurement solutions.
1. Outstanding Material Properties: The Foundation of Precision & Durability
Granite, as the core material of these measuring tables, boasts a series of characteristics that perfectly align with the strict demands of precision measurement.
High Hardness for Long-Lasting Wear Resistance
On the Mohs hardness scale, granite ranks at a high level (typically 6-7), far exceeding ordinary metal or synthetic materials. This high hardness endows granite measuring tables with excellent wear resistance. Even under long-term, high-frequency use—such as daily placement of heavy measuring instruments or repeated sliding of tested workpieces—the table surface remains free from scratches, dents, or deformation. It can maintain consistent flatness and measurement accuracy for years, eliminating the need for frequent maintenance or replacement and reducing long-term operational costs for your business.
Excellent Thermal Stability: No More Accuracy Deviations from Temperature Changes
Temperature fluctuations are a major enemy of precision measurement, as even tiny thermal expansion or contraction of the measuring platform can lead to significant errors in test results. Granite, however, has extremely low thermal conductivity and thermal expansion coefficient. Whether in a workshop with varying day-night temperatures, an air-conditioned laboratory, or a production environment with seasonal temperature shifts, granite measuring tables hardly react to temperature changes. They keep the table surface stable without warping or dimensional changes, ensuring that your measurement data remains accurate and reliable in any working condition.
Strong Compressibility & Corrosion Resistance: Adapt to Harsh Working Environments
With its dense internal structure, granite has high compressive strength (usually over 100MPa). This means granite measuring tables can easily bear the weight of heavy equipment (such as coordinate measuring machines, optical comparators) and large workpieces without bending or deformation, providing a solid and stable base for your measurement operations.
Moreover, granite is inherently resistant to most chemicals. It will not be corroded by common workshop substances like cutting fluids, lubricating oils, or cleaning agents, nor will it rust or deteriorate due to humidity. This corrosion resistance ensures that the measuring table maintains its performance even in harsh industrial environments, significantly extending its service life and maximizing your investment value.
2. Well-Designed Structural Features: Further Enhancing Measurement Precision
Beyond the advantages of the material itself, the structural design of granite measuring tables is optimized to meet the highest standards of precision measurement.
Ultra-Flat & Smooth Surface: Minimize Friction, Maximize Accuracy
The surface of every granite measuring table undergoes a multi-step precision grinding process (including rough grinding, fine grinding, and polishing), resulting in an ultra-high flatness (up to 0.005mm/m) and smooth finish. This smooth surface minimizes friction between the tested workpiece and the table during measurement, preventing scratches on the workpiece and ensuring that the workpiece can be positioned or moved accurately. For tasks that require precise alignment (such as parts assembly testing or dimensional verification), this feature directly improves the efficiency and accuracy of the measurement process.
Uniform & Compact Internal Structure: Avoid Stress Concentration & Deformation
Unlike metal platforms that may have internal defects (such as bubbles or inclusions) due to casting processes, natural granite has a uniform and compact internal structure with no obvious pores, cracks, or impurities. This structural uniformity ensures that the stress on the granite measuring table is evenly distributed when bearing weight or facing external forces. There is no risk of local deformation or damage caused by stress concentration, further guaranteeing the long-term stability of the table’s flatness and precision.
