Focus on breakthroughs in domestic technologies

I. From "Choke Point" to "Parallel Runner" : The Technological Comeback of Domestic Gantry Machining Centers

In the field of high-end equipment manufacturing, gantry machining centers were long restricted by the technical barriers of countries such as Germany and Japan. In February 2026, the high-precision gantry machining center independently developed by China General Technology Group came into the public eye through the "Intelligent Manufacturing for the Future" series of micro-documentaries on Guangming.com. This achievement marks that China has broken the foreign technological monopoly in the field of large precision machine tools and achieved a key leap from "following" to "keeping pace". This equipment has reached the leading domestic and advanced international levels in core indicators such as precision control and structural design. It not only fills the gap in the domestic high-end precision gantry processing field, but also provides reliable domestic equipment support for major national projects such as aerospace and energy power.

Ⅱ. Technological Breakthroughs: Breaking through the dual limits of precision and structure

(1) The realization path of micron-level precision

The core breakthrough of high-precision gantry machining centers lies in precision control technology. Due to insufficient structural rigidity and backward thermal deformation compensation technology, traditional domestic gantry machine tools are difficult to meet the processing requirements of complex parts in aerospace. General Technology Group has innovatively designed the gantry frame structure and adopted the integral casting and aging treatment process to control the shape and position tolerance of the machine tool's basic components within 0.005mm. At the same time, an intelligent compensation system based on real-time temperature monitoring was developed. Through 12 temperature sensors, it dynamically monitors key parts such as the main shaft and guide rails, reducing the thermal deformation error to within ±0.01mm and achieving processing accuracy at the micrometer level.

(2) Engineering Practice of Structural Innovation

In terms of structural design, this gantry machining center adopts a moving table and moving beam layout, which not only retains the high rigidity of the fixed beam machine tool but also possesses the flexibility of the moving beam machine tool. By optimizing the connection structure between the crossbeam and the column and adopting a double hydraulic cylinder balancing system, the vibration amplitude of the machine tool during full-load processing is controlled within 0.002mm, ensuring the stability of processing complex curved surface parts. In addition, the five-axis linkage swing head equipped on the equipment can achieve a swing range of ±120°, capable of completing the one-time forming processing of complex parts such as aero engine blades and rocket fuel tanks.

Ⅲ. Industrial Empowerment: The Core Force Supporting Major National Projects

(1) Application value in the aerospace field

In the aerospace field, high-precision gantry machining centers have become core equipment for the manufacturing of domestic large aircraft, carrier rockets and other equipment. Take the processing of the fuselage docking frame of the C919 large aircraft as an example. The traditional processing method requires five rounds of clamping and 12 procedures, with a processing cycle of up to 15 days. By adopting this gantry machining center, all processes can be completed in one clamping through five-axis linkage technology, with the processing cycle shortened to 7 days and the dimensional accuracy stably controlled within ±0.01mm, meeting the strict airworthiness standards of large aircraft.

(2) The Efficiency Revolution in Energy Equipment Manufacturing

In the field of energy and power, this equipment provides solutions for the processing of heavy components such as 1 million kilowatt-level steam turbine rotors and pressure vessels in nuclear power plants. For the processing of complex curved surfaces of steam turbine rotors, the equipment adopts high-speed cutting technology, increasing the processing efficiency by 40%. The real-time monitoring of the processing process through the online measurement system has increased the product qualification rate from 92% to 99.5%, laying a foundation for the independent manufacturing of energy equipment in our country.

Iv. Industry Impact: Promoting the localization process of high-end equipment manufacturing

(1) The strategic significance of breaking technological monopolies

The successful development of high-precision gantry machining centers has broken the long-term monopoly of foreign enterprises in the field of high-end precision machine tools. Previously, the price of imported similar equipment was as high as over 20 million yuan, and there were problems such as technological blockades and lagging after-sales services. The price of domestic equipment is only 60% of that of imported products, and it has the ability to provide customized services. It can carry out technological upgrades and functional expansions according to user demands, reducing production costs for domestic manufacturing enterprises and enhancing their market competitiveness.

(2) Drive the coordinated development of the industrial chain

This technological breakthrough not only increased the market share of domestic gantry machining centers, but also drove the development of the upstream key component industry. The core components such as high-precision guide rails and lead screws adopted by the equipment are all independently developed and manufactured by domestic enterprises, promoting the localization process of the machine tool industry chain. Meanwhile, General Technology Group has established joint laboratories with 12 domestic universities and research institutions through the industry-university-research cooperation model, cultivating a group of high-end machine tool R&D talents and providing talent support for the continuous innovation of the industry.

V. Future Outlook: The development directions of Intelligence and Greenness

With the advent of the Industry 4.0 era, gantry machining centers are developing in the direction of intelligence and greenness. In the future, domestic gantry machining centers will further integrate technologies such as artificial intelligence and the Internet of Things to achieve autonomous decision-making and intelligent optimization in the processing process. Through the application of lightweight structural design and energy-saving drive systems, the energy consumption of equipment is reduced by more than 30%, promoting the development of high-end equipment manufacturing towards a green and sustainable direction. Meanwhile, with the rapid development of emerging industries such as aerospace and new energy vehicles, the market demand for gantry machining centers will continue to grow, and domestic equipment is expected to occupy a larger share in the global high-end machine tool market.
