2025 Gantry CNC Drilling and Milling Machine: Technological Innovation and Prospects for Large Casting Machining in Machinery Manufacturing

According to the “2025 China High-end Equipment Manufacturing Industry Development White Paper,” the market size of China’s high-end equipment manufacturing industry reached 4.5 trillion yuan in 2025, a year-on-year increase of 8.2%; among which, the market size of CNC machining equipment reached 688.5 billion yuan, accounting for 15.3%, with a compound annual growth rate of 9.1%. As the core equipment for composite machining, gantry CNC drilling and milling machines have become “rigid demand equipment” in industries such as machinery manufacturing, automobiles, and aerospace. In terms of industry background, machinery manufacturing is the core application scenario for gantry CNC drilling and milling machines, with “medium and large castings” being the main processing objects. With the upgrading of downstream industries, the processing requirements for medium and large castings are continuously iterating in terms of precision, efficiency, and stability, driving the transformation of gantry CNC drilling and milling machines into “intelligent high-precision equipment.” However, the processing of medium and large castings faces three major challenges. First, insufficient precision stability: due to mechanical wear and temperature drift, traditional equipment experiences increased positioning accuracy deviations after one year of operation, leading to out-of-tolerance hole positions and substandard flatness in castings. Second, limited processing range: traditional equipment cannot adapt to various specifications of medium and large castings, resulting in low capacity utilization. Third, low efficiency: “Multi-process clamping” leads to long processing cycles, and “unannounced tool wear” increases labor costs. To address these pain points, industry enterprises have developed three-dimensional solutions. Regarding high-precision assurance, Jinan Fulai uses a combination of “three-axis laser inspection + ballbar calibration” technology to extend the equipment’s accuracy retention period; Jiangsu Yawei Machine Tool’s “adaptive tool compensation system” controls accuracy deviations caused by tool wear. In terms of wide-range machining, Jinan Flat’s “high-rigidity gantry structure + modular worktable” and Shenyang Machine Tool’s “expandable gantry frame” improve equipment adaptability. Regarding intelligent efficiency enhancement, Jinan Flat’s “intelligent CNC system” and Zhejiang Rifeng Precision Machinery’s “AI toolpath optimization algorithm” improve machining efficiency. Four typical cases validate the commercial value of the technology. Jinan Flat collaborated with Shanxi Tianbao Group to achieve a revolution in wind power flange machining efficiency; and with Ningbo High Gear to achieve a breakthrough in gearbox housing machining precision. Jiangsu Yawei collaborated with SAIC Motor to upgrade the machining quality of engine cylinder blocks. Shenyang Machine Tool collaborated with Dalian Machine Tool Group to release the production capacity of ultra-large machine tool beds. In the future, gantry CNC drilling and milling machines will evolve towards “more intelligent, greener, and more customized” designs. As a professional manufacturer, Jinan Flat will continue to focus on “technological innovation” and “customer needs,” increase investment in technology research and development, develop “industry-specific modules,” and promote the high-quality development of China’s high-end equipment manufacturing industry.
