Roundtest RA-H5200/RA-H5200CNC-Series 211-Roundness/Cylindricity Measuring System

Series 211


RA-H5200AS / AH, a roundness/cylindricity measuring system developed to combine
world-class accuracy with maneuverability/high analysis capability.
Enhanced detector safety functions such as accidental touch and collision detection
is installed to minimize damage to both machine and workpieces.
