In recent years, with the country's strong support for high-end equipment manufacturing, precision transmission technology has become a key support for the development of the industry. Driven by the policies of intelligent manufacturing and Industry 4.0, truss manipulators, as the core equipment of automated production lines, have continued to expand their application scope. Truss manipulators have the characteristics of high precision and high efficiency, which can significantly improve the automation level of production lines and meet the dual needs of modern manufacturing for production efficiency and product quality.In the field of machine tools, precision racks are a key transmission component, and their performance directly affects the machining accuracy and stability of machine tools. On the current market, precision racks are mainly divided into two types: grinding racks and precision milling racks. The grinding rack is processed through a high-precision grinding process, with low tooth surface roughness and high transmission accuracy. It is widely used in high-precision CNC machine tools and precision measurement equipment. The fine milling rack occupies an important position in the field of mid-to-low-end machine tools due to its high processing efficiency and relatively low cost.In terms of servo systems, domestic and foreign brands compete fiercely. Japanese brand servo systems are known for their high precision and stability, and are widely used in high-end machine tools and robots. Precision rack products from Germany and Switzerland have become the first choice for high-end equipment manufacturing due to their excellent processing technology and material properties. For example, Germany's Atland rack and Switzerland's Goodell rack are well-known in the field of precision transmissions, and their products perform well in terms of tooth surface accuracy and wear resistance.With the in-depth implementation of industry policies, precision transmission technology is ushering in new development opportunities. Enterprises should seize this opportunity, increase investment in R & D, and improve product quality and technical level to meet the growing demand for precision transmission components in high-end equipment manufacturing. At the same time, technical exchanges and cooperation within the industry will also promote the improvement of the overall level and promote the development of precision transmission technology in the direction of higher precision and higher efficiency.
