Measurement machines are an indispensable technology and service category in manufacturing for product quality assurance, process control, and research and development. They contribute to high-precision measurement of dimensions, shapes, surface roughness, hardness, and other properties of parts and products, enabling pass/fail judgments against design values and quality improvement. Representative equipment includes coordinate measuring machines (CMMs), vision measuring machines, form measuring machines, surface roughness testers, and hardness testers, ranging from contact to non-contact types and from manual to fully automated systems. These machines are utilized at various stages such as incoming inspection, in-process inspection, and final inspection, contributing to ensuring traceability and preventing defects. In recent years, data analysis and automation through integration with IoT and AI have advanced, significantly contributing to improved productivity and cost reduction. Furthermore, equipment calibration and measurement subcontracting services are also important elements.
