A granite precision platform is the foundation of many measurement and inspection systems. Its accuracy and stability directly affect the reliability of the entire precision process. However, even a perfectly manufactured granite platform can lose accuracy if not installed correctly. Ensuring that the installation is firm, level, and vibration-free is essential for long-term performance.
1. Why Installation Stability Matters
Granite precision platforms are designed to provide a stable reference surface. If the installation base is uneven or not properly supported, the platform may experience stress or micro-deformation over time. This can lead to measurement deviations, surface distortion, or long-term alignment issues—especially in CMM, optical inspection, or semiconductor equipment.
2. How to Determine If Installation Is Secure
A properly installed granite platform should meet the following conditions:
-
Leveling Accuracy: The surface should remain level within the required tolerance, typically within 0.02 mm/m, verified by an electronic level or precision spirit level (such as WYLER or Mitutoyo).
-
Uniform Support: All support points—usually three or more—must carry an equal load. The platform should not rock or shift when gently pressed.
-
No Vibration or Resonance: Check for vibration transfer from surrounding machines or floors. Any resonance can gradually loosen supports.
-
Stable Fastening: Bolts or adjustable supports should be tightened firmly but not excessively, preventing stress concentration on the granite surface.
-
Recheck After Installation: After 24 to 48 hours, recheck the level and alignment to ensure the foundation and environment have stabilized.
3. Common Causes of Loosening
Although granite itself does not deform easily, loosening may occur due to temperature fluctuations, ground vibration, or improper support leveling. Over time, these factors can reduce installation tightness. Regular inspection and re-leveling help maintain long-term accuracy and prevent cumulative errors.
4. ZHHIMG® Professional Installation Recommendation
At ZHHIMG®, we recommend performing installation in a controlled environment with stable temperature and humidity, using precision leveling systems and anti-vibration foundations. Our technical team can provide on-site guidance, calibration, and stability inspection to ensure every granite platform meets its designed precision for years of operation.
Conclusion
A granite precision platform’s accuracy depends not only on its material quality but also on the stability of its installation. Proper leveling, uniform support, and vibration isolation ensure the platform performs to its full potential.
