Ultra-precision micro-machining processes such as diamond micro-milling are used to efficiently manufacture optical quality surfaces. These processes require high stiffness spindles with low synchronous and asynchronous error motions throughout the range of desired spindle speeds. This paper describes dynamic testing of a 50,000 RPM micro-machining air bearing spindle with nanometer-level error motions capable of producing optical quality surfaces.
