Take the marble table as the measurement datum.
Measure the relative position of the guide rail body and the parts:
the parallel and maximum generatrix can be adjusted to ensure the measurement accuracy.
The inner raceway of outer ring and outer raceway of inner ring can be measured separately, raise the work efficiency.
Low noise digital contour detector.
Wide range no guide head roughness detector.

Contour detector range：0~40mm
Roughness detector range：±620μm
Contour linear accuracy[1]：≤±(1.8+|0.15H|)μm
Roughness linear accuracy：≤6%
