Installing a large granite precision platform is not a simple lifting task — it is a highly technical procedure that demands precision, experience, and environmental control. For manufacturers and laboratories that rely on micron-level measurement accuracy, the installation quality of the granite base directly determines the long-term performance of their equipment. That is why a professional construction and calibration team is always required for this process.
Large granite platforms, often weighing several tons, serve as the foundation for coordinate measuring machines (CMMs), laser inspection systems, and other high-precision instruments. Any deviation during installation — even a few microns of unevenness or improper support — can lead to significant measurement errors. Professional installation ensures that the platform achieves perfect alignment, uniform load distribution, and long-term geometric stability.
Before installation, the foundation must be prepared carefully. The floor should be strong enough to support concentrated loads, perfectly flat, and free of vibration sources. Ideally, the installation site maintains a controlled temperature of 20 ± 2°C and humidity between 40–60% to avoid thermal distortion of the granite. Many high-end laboratories also include vibration isolation trenches or reinforced bases beneath the granite platform.
During the installation, specialized lifting equipment such as cranes or gantries is used to safely position the granite block at its designated support points. The process is typically based on a three-point support system, which guarantees geometric stability and avoids internal stress. Once positioned, engineers perform a meticulous leveling process using precision electronic levels, laser interferometers, and WYLER inclination instruments. Adjustments continue until the entire surface meets international standards such as DIN 876 Grade 00 or ASME B89.3.7 for flatness and parallelism.
After leveling, the platform undergoes a full calibration and verification process. Every measurement surface is inspected using traceable metrology instruments such as Renishaw laser systems, Mitutoyo digital comparators, and Mahr indicators. A calibration certificate is issued to confirm that the granite platform meets its specified tolerance and is ready for service.
Even after successful installation, regular maintenance remains essential. The granite surface should be kept clean and free from oil or dust. Heavy impacts must be avoided, and the platform should be recalibrated periodically — typically once every 12 to 24 months depending on usage and environmental conditions. Proper maintenance not only extends the platform’s lifespan but also preserves its measurement accuracy for years.
