Nikon MCAx25+ Manual Coordinate Measuring Arm

The Nikon MCAx25+ Manual Coordinate Measuring Arm is a 2.5m 7-axis measuring arm with an accuracy of 0.038mm. Nikon MCAx25+ measuring arms are precise, portable and reliable 7-axis coordinate measurement tools ideal for use in the metrology lab, on the shop floor and in-the-field. due to their accuracy. The Nikon MCAx25+ pairs with both ModelMaker MMDx digital handheld laser scanners and Focus Handheld scanning and inspection software. The MCAx25+ arm can be equipped with a wide range of probing systems for laser scanning, touch-trigger measurements and continuous scanning. H120 Scanner & Polyworks included.

¹The Point Repeatability Test (or SPAT) is the reference test to determine measurement arm repeatability with ball probe. The cone is in front of the machine. Points are measured from multiple approach directions. The average point and the deviation of each point to the average center are calculated. The result is the maximum range divided by two.

²The Volumetric Accuracy Test most accurately represents the reasonable expectations for machine performance in practical measuring applications since it involves measuring a certified length standard many times in several locations and orientations and compares the resultant measurements to the actual length. The Volumetric Length Accuracy Test is the most appropriate test for determining machine accuracy and repeatability. The result is the maximum deviation of the measuring distance less the theoretical length. The published value is the pass-off specification for ASME B89.4.22 Volumetric Performance and VDI/VDE 2617-9 probing form (MPEPF) & Indication for size (MPEE). Probing specifications are relevant to both the center and offset probe ports of the MCAx arm. The specifications are achieved under stable environmental conditions with the MCAx arm mounted on a base plate or magnetic base and using 15 mm diameter, 50 mm long, steel ball probes connected to both probe ports.
