METRIS-NIKON MCA II 5124 measuring machine

METRIS-NIKON MCA II 5124 measuring machine built in 2011 is a versatile device that can be used for measuring both small-sized objects as well as complex, large-sized parts. In addition, thanks to the computerisation of measurement procedures and its compact design, the machine can be used directly in the production environment or even inside the measured objects.

The measurement process starts with an angular displacement of the arms to ‘pass’ through reference points. The operator then brings the machine’s measuring tip to the surface of the measured workpiece and validates the coordinates using a button located on the head. The coordinates are then transformed by the calculation procedures to the cartesian system (X,Y,Z), where they are used as the basis for determining the dimensions by approximation of the measured features and geometric figures, i.e. circles, cylinders and cones.

The MCA II METRIS 5124 coordinate measuring arm allows for the following operations:
– measurement of dimensional and geometric deviations of workpieces
– measurement of parts with regular geometric shapes
– measurement of parts with curved surfaces
– digitalisation of objects
