In precision measurement and metrology, every micron matters. Even the most stable and durable granite precision platform can be affected by its installation environment. Factors such as temperature, humidity, and vibration play a critical role in maintaining long-term accuracy and dimensional stability.
1. The Influence of Temperature
Granite is known for its low coefficient of thermal expansion, but it is not completely immune to temperature changes. When exposed to fluctuating temperatures, the granite surface can experience slight dimensional variations, especially in large platforms. These changes, though minimal, can still affect CMM calibration, precision machining, or optical inspection results.
For this reason, ZHHIMG® recommends installing granite precision platforms in an environment with constant temperature, ideally around 20 ± 0.5 °C, to maintain measurement consistency.
2. The Role of Humidity
Humidity has an indirect yet significant influence on precision. Excessive moisture in the air can lead to condensation on measuring instruments and metal accessories, potentially causing corrosion and subtle deformation. On the other hand, extremely dry air may increase static electricity, attracting dust and micro-particles onto the granite surface, which can interfere with flatness accuracy.
A stable relative humidity of 50%–60% is generally ideal for precision environments.
3. The Importance of Stable Installation Conditions
Granite precision platforms should always be installed on a stable, vibration-isolated foundation. Uneven ground or external vibrations can cause stress or deformation in the granite over time. ZHHIMG® recommends using precision leveling supports or anti-vibration systems to ensure long-term stability, especially in facilities with heavy equipment or frequent movement.
4. Controlled Environment = Reliable Measurement
To achieve reliable measurement results, the environment should be:
-
Temperature-controlled (20 ± 0.5 °C)
-
Humidity-controlled (50%–60%)
-
Free from vibration and direct airflow
-
Clean and dust-free
At ZHHIMG®, our production and calibration workshops maintain constant temperature and humidity conditions, with anti-vibration flooring and air purification systems. These measures ensure that every granite platform we produce meets international metrology standards and maintains accuracy over years of use.
Conclusion
Precision begins with control—of both material and environment. While granite itself is a stable and reliable material, maintaining proper temperature, humidity, and installation conditions is essential for achieving and preserving accuracy.
ZHHIMG® provides not only precision granite platforms but also installation guidance and environmental solutions to help our clients achieve the highest standards in precision measurement and industrial performance.
