Core Selling Points

• Ultra-High Flatness Precision: Precision grades cover 000/00/0/1, flatness error ≤0.002mm/m (Grade 000), compliant with GB/T 20428-2006 and JB/T 10027-2016 standards, providing stable reference surfaces for various precision operations
• High-Quality Natural Base Material: Made of high-density natural marble/granite, with hundreds of millions of years of natural aging treatment, complete release of internal stress, non-magnetic, non-conductive, Shore hardness ≥HS75, wear-resistant and corrosion-resistant, and the surface is not easy to scratch or deform
• Extreme Structural Stability: Low coefficient of thermal expansion (≤5.0×10^-6/℃), excellent thermal stability, can maintain high precision at room temperature and in environments with small temperature fluctuations, no creep or settlement after long-term use
• Precision Grinding Process: The working surface undergoes multiple refined processes such as rough grinding, precision grinding and polishing, surface finish up to Ra0.012μm, uniform flatness, close fit with the tested parts/tooling, and uniform load-bearing (unit area load-bearing ≤200kg/㎡)
• Multi-Scenario Adaptation: Supports various tabletop processing (smooth surface, T-slot, threaded hole, etc.), no oiling required for rust prevention, daily cleaning with a lint-free cloth is sufficient, suitable for long-term stable use in laboratories, precision workshops, metrological detection and other scenarios

Usage Notes

• Store in a dry, flat and vibration-free environment, avoid moisture, exposure to sunlight, rain and severe collision. It is recommended to support with a special wooden bracket or shockproof pad to ensure uniform force on the platform and prevent deformation under pressure; regularly check the cleanliness and flatness of the tabletop during long-term storage.
• Ensure the installation foundation is flat and firm during installation, adopt multi-point uniform support, use a level to calibrate the levelness of the platform, and ensure the flatness meets the usage requirements; after installation, let it stand for 24 hours before use to avoid precision fluctuations caused by immediate force.
• Before use, gently wipe the tabletop with a lint-free cloth dipped in neutral detergent to remove dust, oil and other impurities to ensure the reference surface is clean; avoid scratching or impacting the tabletop with hard objects. If there are stubborn stains, do not scrape them with sharp tools, and use special cleaning products to handle them.
• Handle with care when placing workpieces or tooling to avoid severe impact; control the load within the rated range to avoid local overloading leading to tabletop deformation or precision damage; lay a protective pad on the tabletop when moving large workpieces to reduce friction damage.
• Perform precision calibration regularly, it is recommended to calibrate every 6-12 months. Calibration shall be carried out by professional metrological institutions in accordance with relevant national standards; if abnormal tabletop precision, surface damage and other conditions are found during daily use, stop the machine in time for inspection and treatment.
