In the field of precision and performance testing of CNC machine tools, laser interferometer measuring systems and ballbars produced by famous foreign companies such as Renishaw, API and HP are in the detection and monitoring of the geometric accuracy and motion accuracy of CNC machine tools. Machine tool manufacturers or machine tool factories have been widely used.
Digital precision measurement technology is one of the key technologies in digital manufacturing technology. Develop sub-micron and nano-scale high-precision measuring instruments, improve environmental adaptability, enhance robustness, and enable precision measurement equipment to enter the production site, integrate into processing machine tools and manufacturing systems, and form an advanced digital closed-loop manufacturing system, which is today's precision measurement technology. The development trend.
FARO Technologies' portable three-coordinate measuring arm from FARO Technologies of the United States is the first in the industry to achieve the perfect combination of measuring arm and laser scanning head, enabling non-contact fast scanning and contact measurement in the same coordinate system. Features: Non-contact flexible and fast scanning, obtaining point cloud data of curved surface, no stratification of point cloud; contact measurement, grasping the accuracy of key feature size and contour; non-contact and contact measurement are perfectly combined in the same coordinate system There is no stratification in the scanning; the scanning head is the same as the measuring arm and the measuring software, and the technology is completely shared and the service is more convenient. In the actual application, the design and manufacturing cycle are greatly shortened for customers, the cost is reduced, the quality control can be completed internally, and the automatically generated report is applicable to the network application, thereby improving communication between various production functions and actual different places; Accuracy, when customizing products, users typically define surfaces by 5 to 10 points, allowing users to verify surface quality defined by tens of thousands of point clouds; automated SPC can automate statistical processes on multiple samples control.
American CIMCORE has introduced an articulated arm measuring machine equipped with an advanced laser scanning measurement system. The material is made of carbon fiber and the INFINITE series also features wireless communication. When used for reverse engineering, not only the measurement speed is fast, but also the real-time display of the measurement process and the seamless splicing of the trapping measurement data. The instrument can be used for three-coordinate measurement, three-dimensional modeling, product mapping, reverse engineering, on-site measurement, and mold design and manufacturing, including measurement, design, manufacturing, process inspection, on-line inspection and final product inspection.
Swiss Scan series of TESA uses two linear array CCD components to project and scan the workpiece through the rotation and axial movement of the workpiece, which can accurately detect the position error and shape error of the shaft parts, and the cross-sectional shape and contour. Evaluation comparisons and statistical mass analysis can also be performed on parts of the part (such as transition curves, tiny grooves, etc.). Accurate measurement of full parameter accuracy for threads, worms, screw rods, etc.
SCHNEIDER's WMM series of shaft and tool measuring instruments are easy to operate and have high measuring speed, especially suitable for workshop inspection stations. The instrument uses a high-resolution Matrix camera to quickly acquire measurement data.

Machine tool manufacturers or machine tool factories have been widely used. Renishaw's laser interferometry system is equipped with high-precision, high-sensitivity temperature, pressure, humidity sensors and EC10 environmental compensation devices to further improve measurement accuracy in the working environment; API's Rmtea six-dimensional laser measurement system can simultaneously measure The error of the accuracy of six CNC machine tools shortens the inspection time and provides a more rapid and efficient measurement method for the detection and diagnosis of CNC machine tools on the production site. The MJS series of dual-frequency laser interferometers from Chengdu Tool Research Institute covers measurement methods and indicators for CNC machine tools in China and the world's major industrial countries. The dynamic sampling function can be used for automatic compensation.
