Continuous breakthroughs in core technologies have led to a comprehensive breakthrough in the precision barriers of high-end machine tools.

As the core foundation of the equipment manufacturing industry, high-end CNC machine tools are a key benchmark for measuring the level of intelligent manufacturing and are also core equipment supporting the development of strategic industries such as aerospace, precision molds, and high-end equipment. For a long time, technological barriers such as ultra-high precision machining, stability of core functional components, and long-term precision maintenance have been key bottlenecks restricting the high-quality development of the high-end machine tool industry. With the continuous increase in industry R&D efforts and the continuous improvement of the industry-academia-research collaborative innovation system, China's high-end machine tool field has achieved successive technological breakthroughs, gradually breaking through the technological limitations in the field of high-precision manufacturing.

Currently, high-end machine tools are iteratively upgrading towards micron-level and sub-micron-level ultra-high machining precision, and many new precision CNC equipment have achieved leaps in key performance. By optimizing the bed casting structure, upgrading the precision ball screw and linear guide transmission system, and combining it with new adaptive closed-loop control technology, the equipment effectively reduces vibration and thermal deformation errors during operation, improving the positioning accuracy and repeatability to the industry's top level. It can stably achieve IT6-IT7 level high-precision workpiece machining, with a workpiece surface roughness of Ra1.6, fully adapting to the mass production needs of high-end precision parts.

In terms of core component self-sufficiency, the industry has continuously tackled key supporting components such as precision spindles, high-speed servo systems, high-precision grating rulers, and precision rotary tables, completely breaking free from the predicament of relying on external suppliers for core components. Newly developed, independently researched electric spindles possess high speed, high rigidity, and low noise characteristics, making them suitable for high-speed cutting scenarios. The service life of core components has reached international first-tier product standards. Simultaneously, the industry has conducted special optimizations to address the shortcomings in machine tool stability and durability. Through the application of new materials and structural process innovations, the long-term precision maintenance capability of equipment has been significantly improved, effectively reducing the later maintenance costs for enterprises.

Technological breakthroughs have driven a comprehensive upgrade of the industry's capabilities. High-end machine tools are now widely used in high-end manufacturing fields such as precision aerospace components, new energy core components, high-end molds, and medical devices. Compared to traditional equipment, the new generation of high-end machine tools offers over 40% higher processing efficiency and significantly improved yield rates, meeting the batch processing needs of complex irregular structures and ultra-high precision parts. Industry insiders say that with the continuous iteration of core technologies, high-end machine tools will continue to solidify the foundation of intelligent manufacturing and drive the equipment manufacturing industry towards in-depth development in high-precision and cutting-edge fields.
