The Composition System and Structural Characteristics of Three Coordinate Measuring Machines in Precision Parts Processing

In the field of precision parts processing, coordinate measuring machines are composed of three major components: the main machine, the measuring head, and the electrical system. The main machine includes a frame structure, a scale system, a guide rail, a driving device, a balancing device, and turntable accessories; The electrical system includes electrical control systems, computer hardware, measurement and software, and printing and drawing devices. Therefore, using a coordinate measuring machine requires familiarity with the basic components of the equipment and basic skills to perform measurement operations.

The structural forms of coordinate measuring machines can be divided into mobile bridge type, fixed bridge type, gantry type, cantilever type, horizontal arm type, column type, horizontal boring type, and instrument desktop type. When using, attention should be paid to the structural characteristics and applicability of the instruments used. The mobile bridge type is currently the most widely used structural form in coordinate measuring machines, with a simple, compact, good stiffness, and relatively open space.

The workpiece is installed on a fixed workbench with strong load-bearing capacity, and the quality of the workpiece has no impact on the dynamic performance of the measuring machine. However, in the field of precision parts processing, small and medium-sized coordinate measuring machines often use this form.
