Only minimal levels of vibration and audible noise are produced when running an air bearing spindle.
As a result of the high balance standards obtained and the lack of mechanical contact, a Westwind air bearing spindle should produce minimal levels of vibration and audible noise.
Typical balance standard: G0.4 or better.
Typical vibration level: <0.2 mm/sec (low speed spindles).
<1.0 mm/sec (high speed spindles).
Typical noise levels: 70 to 80 dBa.
