Shanghai Daoqin Testing Instrument Co., LTD

A high-precision CNC gantry-type coordinate measuring machine (CMM) is a precision 3D measurement device based on CNC technology and a gantry-type structure. It boasts micron-level measurement accuracy (e.g., ±(1.5+L/300)μm) and an extremely large measuring range (customizable travel ranges up to several meters). It is suitable for high-precision dimensional, geometric tolerance, and 3D contour inspection of complex workpieces. This device utilizes a highly rigid gantry structure, equipped with precision linear guides, a servo drive system, and linear encoder feedback to ensure stability and repeatability (≤0.8μm). It is available with optional touch, scanning, or laser probes to meet diverse needs. Automated measurement programming is enabled by a full CNC system (such as PC-DMIS), supporting GD&T analysis, CAD comparison, and SPC statistics. It can be integrated with robotic loading and unloading systems to meet the needs of smart manufacturing. Its granite or aluminum alloy crossbeam design offers excellent thermal stability, and combined with environmental compensation technology, it effectively reduces the effects of temperature drift and vibration. It is widely used in aerospace (wings, engine components), automotive manufacturing (body sheet metal, battery boxes), precision molds and scientific research measurement fields. It combines efficient batch testing with laboratory-level accuracy and is an ideal solution for quality control in high-end manufacturing.
