It still works without forced air, just not nearly as well. You really need to force the fluid to get the high carrying capacity, or use a higher viscosity fluid so it doesn't get displaced as easily, which is actually how standard ball bearings work. A moving ball bearing has no contact between any metal parts.
The spindle products range from small engraving air bearing spindles to large oil bearings in cold iron and steel milling machines; the stages range from small single axis stage to multi degree of freedom stages. We provide our standard off the shelf products but …
Having read about air bearings, I was concerned that this simple approach wouldn't work properly but it works well on the cutters I've tried (1/2, 7/16, and 3/8 (an air bearing may be needed for smaller cutters, I haven't attempted anything under 3/8" yet). I found the cutter …
Air-Bearing End Mill Grinding Fixture. Allows precision sharpening of end mills, reamers, shell mills and other cutters. The spindle is supported with a thin film of air providing nearly frictionless motion, resulting in a smooth, even grind. The fixture is available with a universal base to fit most tool and cutter or surface grinders.
Air bearings use compressed air blown into a small gap between the spindle and the bearing surface. The spindle floats on an even cushion of compressed air. The non-contact type of bearing means the spindle has a very long service life because of low friction and wear; it also means that the spindle generates almost no heat or vibration.
