The Air Bearing Granite Platform is a cutting-edge precision positioning base that utilizes air flotation technology to achieve ultra-smooth, frictionless movement. Designed primarily for high-precision inspection, metrology calibration, and scientific research applications, it combines the structural stability of natural granite with the advanced performance of air bearing systems.
Working Principle
This platform operates by forming a stable air film-typically 10 to 15μm thick-under the granite base via compressed air, creating a nearly frictionless surface. The multi-nozzle air bearing system, combined with dynamic air pressure regulation (often via vacuum pumps), enables micro-level motion in all six degrees of freedom. This results in sub-micron positioning accuracy, with movement resolution reaching as fine as 0.01mm. Compared to conventional cast iron bases, this system offers over 30% improvement in accuracy and zero mechanical wear.
Key Features & Applications
✅ Ultra-Precise Motion Control
Fine-tuned pneumatic adjustments allow micron-level displacement, making it ideal for microgravity simulation, precision scanning, or magnet alignment. For example, in accelerator systems, magnetic field mapping accuracy can reach ±0.01T.
✅ Stable Load-Bearing Granite Construction
Crafted from high-quality natural granite or marble, the platform offers uniform density, low porosity, and superior dimensional stability. Surface roughness is typically Ra ≤ 0.8μm, with load capacities exceeding 4 tons. Under temperature-controlled conditions (20°C), the platform maintains micron-level flatness and planarity.
✅ Multi-Axis Synchronized Movement
Equipped with linear motor drives and optional rotary stages, the system allows precise X/Y/Z and angular adjustments with movement increments of 0.01mm, ideal for advanced mechanical assembly and testing tasks.
Operational Guidelines & Maintenance
Calibration: Prior to use, perform surface flatness calibration. Seam gaps should remain below 0.01mm. Adjust air pressure in real time for optimal leveling and stability.
Cleaning: Wipe the surface regularly with a lint-free cloth. Neutral pH cleaners should be used in case of acid or alkali contact to prevent etching.
Protection: Apply stone protectant every six months and consider surface waxing to maintain optimal performance and prevent micro-abrasion.
Load Distribution: Avoid overloading or placing excessive weight unevenly. Maintain load uniformity under 150kg/m² to preserve structural integrity.
