Plate-forme à coussin d'air en granit de précision
I. Core Principles and Structural CompositionWorking Principle: High-pressure clean air is sprayed through porous graphite/throttle hes to form a uniform air film of 5–15 μm between the granite base and the moving slide; contactless levitation achieves zero-friction motion, while relying on air fitiffness for load-bearing and guidance; often combined with vacuum preloading/magnetic preloading to enhance…
