Coordinate Measuring Machines (CMMs) represent one of the most demanding applications in industrial metrology, requiring extreme structural stability and vibration isolation to ensure measurement accuracy at micron and sub-micron levels.
Precision granite remains the dominant material for CMM base structures due to its inherent damping properties, long-term dimensional stability, and resistance to thermal deformation. Unlike metallic structures, granite does not exhibit residual stress relaxation over time, making it ideal for high-precision reference planes.
ZHHIMG® manufactures large-scale granite structures capable of supporting metrology systems up to 20 meters in length and individual components weighing up to 100 tons. These capabilities enable the production of custom inspection platforms for aerospace, automotive, and semiconductor industries.
Applications include high-end CMM machines, optical coordinate systems, laser alignment tables, and industrial CT/X-ray inspection systems. These systems require base structures that maintain geometric integrity under continuous operational stress and environmental variation.
Internal verification processes confirm that vibration damping performance of granite platforms significantly reduces signal noise in laser interferometry-based measurement systems. This directly improves repeatability and reduces calibration drift over extended operating cycles.
ZHHIMG® production systems comply with ISO 45001 occupational safety standards and ISO 14001 environmental management standards, ensuring sustainable and controlled industrial manufacturing conditions.
