Features of low speed roundness measuring instrument:
1. High precision: with high precision air bearing, precision 0.05-0.2μm
2. High measurement accuracy: using gemstone or steel probe, low speed, no attenuation of measurement, accurate waviness measurement, especially suitable for final
determination of roundness and waviness.
