Turning and milling composite processing technology is a composite processing technology that integrates turning and milling. It uses a highly integrated CNC system to accurately control the tool's motion trajectory, speed and cutting parameters to achieve one-time clamping and multi-process processing of complex parts. This technology not only improves production efficiency, but also significantly improves processing accuracy and surface quality. It is an important development direction in the field of modern precision machining.

As a key component in the mechanical system, the accuracy and surface quality of the inner and outer surfaces of copper sleeve parts directly affect the performance and life of the entire system. The use of turning and milling composite processing technology to process copper sleeve parts has the following significant advantages:
High-precision processing: Turning and milling composite processing equipment uses advanced CNC systems and precision servo drive technology to achieve precise control of the tool's motion trajectory. When processing copper sleeve parts, it can ensure that the dimensional accuracy of the inner and outer surfaces meets the design requirements, and even reaches micron-level accuracy. This high-precision processing capability is essential to ensure the stability and reliability of parts during assembly and use.
Low surface roughness: Surface roughness is one of the important indicators for measuring the surface quality of parts. Milling-turning composite processing technology can achieve fine processing of the surface of copper sleeve parts by optimizing cutting parameters and tool paths. During the processing, the tool cuts with a small step amount, so as to obtain a lower surface roughness while ensuring processing efficiency. This low surface roughness not only improves the aesthetics of the parts, but also provides a good foundation for subsequent silver plating.
Multi-process integration: Milling-turning composite processing equipment integrates turning and milling functions, and can complete multiple processing tasks in one clamping. This reduces the number of transfers and clampings of workpieces between machine tools, and reduces the positioning error and surface damage risk caused by multiple clamping. Multi-process integration also improves processing efficiency and shortens production cycles.
Intelligent monitoring and adjustment: Some high-end milling-turning composite processing equipment is also equipped with intelligent monitoring and fault diagnosis systems. These systems can monitor key parameters such as cutting force, temperature distribution, vibration, etc. during the processing process in real time, and can automatically adjust cutting parameters or stop alarms once abnormal conditions are found. This intelligent monitoring and adjustment capability ensures the stability and reliability of the machining process, and further improves the machining quality and surface quality of the parts.

The following is a specific application example of customizing silver-plated copper sleeve parts using milling and turning composite machining technology:
Part drawing analysis and process planning: Analyze the structural characteristics, dimensional accuracy requirements and material properties of the copper sleeve parts according to the part drawings. Then, formulate a detailed machining process route, including tool selection, cutting parameter setting, and machining sequence arrangement. In the process of process planning, it is necessary to fully consider the characteristics and advantages of milling and turning composite machining technology to ensure machining quality and efficiency.
Tool selection and cutting parameter optimization: According to the cutting performance of copper materials and the machining requirements of parts, select the appropriate tool type and geometric parameters. Determine the optimal cutting parameters (such as cutting speed, feed rate, cutting depth, etc.) through experiments and optimization to ensure low surface roughness and high-precision internal and external surfaces.
Milling and turning composite machining implementation: Use milling and turning composite machining equipment to process copper sleeve parts. During the machining process, by accurately controlling the motion trajectory and cutting parameters of the tool, high-precision machining and low surface roughness control of the internal and external surfaces of the parts can be achieved. The intelligent monitoring and fault diagnosis system of the equipment is used to monitor the processing process in real time to ensure the stability and reliability of the processing process.
Surface quality inspection and evaluation: After the processing is completed, the surface quality of the copper sleeve parts is inspected and evaluated using high-precision inspection equipment. This includes surface roughness measurement, dimensional accuracy inspection, shape and position tolerance inspection, etc. Through the inspection and evaluation results, it can be judged whether the processing quality meets the design requirements, and provide a reliable basis for the subsequent silver plating treatment.
Silver plating and quality control: After the surface quality of the copper sleeve parts meets the design requirements, silver plating is carried out. During the silver plating process, parameters such as plating solution composition, temperature, and current density need to be strictly controlled to ensure the uniformity and adhesion of the silver plating layer. The silver-plated parts are quality inspected and controlled to ensure that the quality and performance of the silver plating layer meet the design requirements.
