A bridge Coordinate Measuring Machine (CMM), such as our Emerald 785 CMM, is a precision measurement device used in manufacturing and quality control processes. It's named for its bridge-like structure, which consists of a stationary base and an overhead bridge that spans the measurement area.
The functioning of a bridge-type CMM involves the use of a probe attached to a moving arm or a gantry that travels along the bridge. The workpiece to be measured is securely placed on a table beneath the bridge.
