Diameter - radial/axial runout - measurement at disk motors
The production of disk motors has to meet the Technical details
highest mechanical accuracy requirements. In - Measuring range:200 µm / 50 µm
order to ensure perfect functioning of the disk - Accuracy: 0,4 µm / 0,1 µm
drives the drive units are measured and evaluated - Resolution: 0,04 µm / 0,01 µm
with respect to diameter, true running, and axial - Band width: 4 kHz (-0,1 dB)
running. Since production tolerances of < 5 µm
have to be measured under nominal speed, a Ambient conditions
decision has been made to use the fast and high- - Ambient temperature (conditioned air)
resolution capaNCDT system. In this measure- - Medium: air
ment two sensors with measurement range50 µm - Clean room conditions
that are adapted to the flange geometry are of
special importance. System configuration capaNCDT series
