Air Bearing Spindle and Rotating Shaft Test

ADE capacitance gauges and capacitive sensors are ideal for measuring the performance of high speed air bearing spindles and other rotating shafts. Since capacitive gauges are high bandwidth, they are capable of gathering data even as the spindle or shaft sweeps through its entire speed range.

As probe noise is often the limiting factor in making critical asynchronous error motion measurements, ADE has developed special ultra-low noise capacitance gauges and probes specifically for high dynamic run out measurement applications.

Spindle Runout Measurement

The MicroSense 5430 enables dynamic measurement of high speed spindle runout to verify spindle performance specifications. Since the 5430 is capable of nanometer resolution, data can be captured to measure and analyze both repeatable run out (RRO) and non-repeatable runout (NRRO). ADE non-contact measurement probes have standard sensors as small as 0.5 mm diameter so that measurements can be made at the toolpoint, using ground cylindrical targets.
