Especially for precision parts such as mandrels, milling can not only provide the required dimensional accuracy, but also ensure the surface finish of the parts. However, existing milling equipment and technology have some limitations in certain specific application scenarios: 1. In some processing workshops, especially gantry drilling machines, their design and functions are mainly for drilling operations and are not suitable for milling. This limits the workshop's ability to perform milling on parts such as mandrels without adding additional equipment; 2. Due to the limitations of equipment in the workshop, many factories have to choose outsourcing to complete milling operations, which not only increases the complexity of logistics and management, but also significantly increases production costs, especially when outsourcing costs are high; 3. Existing milling tools and processing methods have shortcomings in processing efficiency, resulting in extended production cycles and affecting overall production efficiency. At the same time, due to frequent tool wear and replacement, production costs are further increased; 4. Milling processing on a vertical drilling machine requires specific tooling to ensure processing accuracy and efficiency; however, existing tooling designs may not meet the needs of high-precision milling, or there may be problems such as inconvenient operation and inaccurate positioning in actual applications.
