[0002] CNC dual-axis drilling, milling, and tapping machines are high-precision machining equipment widely used in modern manufacturing, primarily for drilling, milling, and tapping processes in metallic or non-metallic materials. With the development of industrial automation and intelligence, CNC machining equipment has played a crucial role in improving production efficiency and machining quality. However, some problems in existing technologies limit further improvements in equipment performance. First, the worktable of traditional CNC drilling and milling machines lacks expandability, making it difficult to flexibly adjust functional modules according to different machining needs, resulting in poor equipment adaptability. Second, the connection stability of the tool head during machining is insufficient; conventional mechanical connections are prone to loosening under high-speed operation or heavy load conditions, affecting machining accuracy and equipment lifespan. These problems not only reduce production efficiency but also increase maintenance costs, limiting the application of the equipment in complex machining scenarios. Therefore, there is an urgent need for a technical solution that can improve the modular expandability of the worktable and the stability of the tool connection to meet the demands of modern manufacturing for high efficiency and high precision.
