The use of air bearings means tool life can be greatly extended.
The lack of vibration and high rotational accuracy means drills, cutters, grinding wheels and boring tools have a much longer life – reducing maintenance and running costs. In particular, in the PCB drilling industry where drill diameters as small as 50 microns are now used, only air bearing spindles are capable of running at the required speeds to ensure acceptable tool life.
Typical increase in grinding wheel life: 1.5 to 4 times dependant on application & wheel type.
