Gas lubrication bearings - bearing of the application of knowledge

Examples in the field of machine tool lubrication bearing gas lubricated bearing in the machine tool is mainly used for the main shaft bearing, including the workpiece shaft, cutter shaft, spindle, etc. Machine tool spindle bearings generally USES air static pressure bearing and static pressure bearing two kinds. Small high-speed spindle wave foil bearing may be adopted. Aerostatic bearings used in machine tools, most of which holes throttling and torus throttle bearing is most common. Porous aerostatic bearings are used in recent years, more and more active static mixed lubrication bearing. Floating ring of dynamic and static pressure gas bearing is in recent years, the new development of the gas lubrication bearings, used in high speed spindle bearing is very promising. Ultra-high speed grinding head air bearing inner circle the grinding speed can reach and tiny hole precision grinding. Using air bearing to improve the machining accuracy of machine tools by the 2 - 3 orders of magnitude, and can realize precision mirror surface treatment.
