Aerostatic supporting technology has many advantages such as high precision, no friction and pollution-free, it has already applied to military industry, aeronautics-space, semiconductor and magneto-optical recording etc. High grade area extensively. We have grasped core techniques of this project: numerical simulation, structure design, precision manufacturing, assembly and performance testing, we have three present parts now: aerostatic supporting axle , aerostatic supporting slideway, aerostatic cushion, we can design parts according customer requirements, our technique already reaches the domestic advanced level . Technological advantages 1, numerical simulation Independently research and develop three dimensional nonlinear gas lubrication simulation analyse software, which can analyse different parameters (dimension, gas pressure, film gap, orifice diameter and place), optimize these parameters to get the most raisonnable result. Through a large number of experimental verification, simulation result can match experimental production perfectly. 2, structure design Independently designed principal axle(upright and horizontal ones), aerostatic supporting slideway, aerostatic cushion etc., the axle combined with journal- antithrust hybrid bearing. We can adjust our design according different rigidity and load bearing requirement using small holes or porous graphite orifice. Our products are no stop up, simple structure and ingenious, facilitate assembly and disassembly, easy safeguard, highly reliable. 3, precision manufacturing and assemble We have ultra precision turning, polishing, grinding and assembly ability, we have accurate testing equipments such as roundness measuring equipment, plane interferometer and coordinate measuring machine, we can finish plane, cylinder and sphere machining and testing, flatness error
