Under the wave of Industry 4.0, precision transmission systems are undergoing profound changes from traditional processing to high precision and high reliability. As a key component in the field of linear transmission, the accuracy of grinding rack directly affects the motion stability and positioning accuracy of the robot. In the current market, high-end products such as Germany's Atland rack and Switzerland's Goodell rack occupy an important position in the field of precision machinery due to their excellent processing technology and material characteristics. Domestic products such as Taiwan's abrasive racks and YYC racks have gradually narrowed the gap with the international advanced level through technological upgrades.In the transmission system architecture, the coordination between TBI screws and servo motors is crucial. The high response performance of Yaskawa Panasonic servo motors combined with the precision transmission characteristics of TBI screws can meet the needs of high-speed, high-load industrial scenarios. At the same time, integrated solutions launched by companies such as Kottec Precision Machinery further simplify system design and improve overall operating efficiency. Market data shows that the market demand for grinding racks will increase by approximately 15% year-on-year in 2023, mainly due to the rapid development of 3C electronics, semiconductor equipment and other industries.At the technical level, the processing technology of precision racks is developing towards higher precision and more complex shapes. The fine milling rack technology can achieve micron tooth profile accuracy through multi-axis linkage machining, meeting the needs of high-end applications. The VASTUN grinding rack uses a special surface treatment process to significantly improve the wear resistance and service life of the rack. In terms of services, industry manufacturers are transforming from simple product sales to full life cycle services, providing comprehensive solutions including precision testing, installation and debugging, and maintenance.In the future, with the continuous advancement of robot technology, the requirements for precision transmission systems will become more stringent. Industry participants need to continue to increase investment in research and development, optimize material selection and processing processes, and at the same time strengthen cooperation with upstream materials and downstream applications to jointly promote breakthroughs and innovations in precision drive system technology.
