WebAs for the traditional CMM, the sensor is a contact probe, the coordinate point is touched by probe one by one, but the VMM vision sensor can catch hundreds of points in one shot, so VMM 2D measuring speed is faster and more precise than CMM. Because the stage of CMM is granite stone, CMM can make a large size with heavy-weight load capability. 5. Web* Qualify CMM probes, make custom probes, setup probe changer and established new calibration routines. * Evaluate inspection results to determine conformance to requirements on drawings and have an understanding on GD&T (example: True Position, Profile, MMC/ LMC, Circularity, Cylindricity, Straightness, Flatness, Concentricity, Runout ...
