Process : Lathe or cutting , milling , grinding , boring , inspection , etc.

What’s air bearing?

An air bearing is a non-contacting system where a gas film (typically air) 
acts as the lubricant that separates the two surfaces in relative motion.

Why use air bearing?

There are benefits for air bearing, as follows:

l        Greater precision

l        High speed

l        Increased tool life

l        Improved surface finish

l        Long bearing life

l        Low thermal growth

l        Lack of maintenance 

l        Large load capacity 

l        Reduced vibration Cleanliness
