Specialized equipment for high-precision measurement of dimensions, shapes, and positions of parts and products in three-dimensional space. Uses contact probes or non-contact sensors to automatically measure and analyze dimensional tolerances, geometric tolerances, and positional accuracy of complex shapes from X, Y, Z coordinate data. Essential for quality inspection of CNC machined parts, mold shape verification, and precision measurement of automotive and aircraft components. Available in gantry, bridge, and horizontal arm configurations, selected based on measurement range and accuracy requirements. Also known as CMM (Coordinate Measuring Machine), one of the most important measuring instruments in manufacturing quality assurance.
