Turning-milling is an advanced machining technology that cleverly combines turning and milling, and can complete multiple processes on the same equipment. This processing method not only improves production efficiency, but more importantly, it ensures the dimensional accuracy and shape accuracy of electric coupling iron parts.
In the processing of electric coupling iron parts, the turning-milling machine tool can achieve high-precision processing of iron parts through precise tool path planning and cutting parameter setting. The turning process is used to process the outer circle, inner hole and other rotating surfaces of iron parts, while the milling process is used to process the plane, groove, complex curved surface, etc. of iron parts. Through the combination of these two processing methods, the turning-milling machine tool can achieve all-round and high-precision processing of electric coupling iron parts, ensuring that the dimensional accuracy and shape accuracy of the iron parts meet the design requirements.
Turning-milling also has the advantages of high processing efficiency, high processing accuracy and wide processing range. It can complete multiple processes in one clamping, reducing the number of clamping times and error accumulation, and improving processing efficiency and processing accuracy. Turning and milling composite machining machines can also process parts with complex shapes and high dimensional accuracy requirements, meeting the needs of electric coupling iron parts for high-precision processing.
In the processing of electric coupling iron parts, black oxidation treatment is usually arranged after turning and milling composite precision processing. Black oxidation treatment is a metal surface treatment technology. Its principle is to generate a dense oxide film on the metal surface through chemical reaction. This oxide film not only has extremely high hardness and wear resistance, but also can effectively isolate the direct contact between the metal and the external environment, preventing corrosive media from corroding the metal surface.
The process of black oxidation treatment usually includes workpiece clamping, degreasing, cleaning, pickling, oxidation, cleaning, saponification and inspection. Among them, oxidation is a key process, which needs to be carried out under specific temperature and time conditions to ensure that the generated oxide film is dense, smooth and uniform in thickness. This oxide film can significantly improve the corrosion resistance and wear resistance of electric coupling iron parts, enabling it to operate stably for a long time in harsh environments.
In a humid environment, the black oxide layer can prevent direct contact between moisture and the metal surface, thereby avoiding electrochemical corrosion caused by moisture. In a high temperature environment, the black oxide layer has high thermal stability, can maintain the stability of its structure and performance, and prevent the metal from softening or deforming due to high temperature. In a corrosive gas environment, the black oxide layer can resist the erosion of acidic or alkaline gases and protect the metal surface from corrosion. Therefore, black oxidation treatment provides a solid protective barrier for the electric coupling iron parts, enabling them to maintain excellent performance and stability in harsh environments.
The combined application of turning and milling composite processing and black oxidation treatment has significantly improved the dimensional accuracy, shape accuracy, corrosion resistance and wear resistance of the electric coupling iron parts. This combined process not only ensures high-precision processing of the electric coupling iron parts, but also extends its service life by improving corrosion resistance and wear resistance.
In the turning and milling composite processing stage, high-precision processing of the electric coupling iron parts is achieved through precise tool path planning and cutting parameter setting. This ensures that the dimensional accuracy and shape accuracy of the iron parts meet the design requirements, providing a good foundation for the subsequent black oxidation treatment. During the black oxidation treatment stage, a dense oxide film is generated on the metal surface through chemical reaction, which significantly improves the corrosion resistance and wear resistance of the iron parts. This enables the electric coupling iron parts to operate stably for a long time in harsh environments, greatly extending the service life.
This combined process also has the advantages of high processing efficiency and low processing cost. Turning and milling composite processing can complete the processing of multiple processes in one clamping, reducing the number of clamping times and error accumulation, and improving processing efficiency. At the same time, black oxidation treatment, as a mature metal surface treatment technology, is relatively low in cost and easy to implement. Therefore, this combined process has broad application prospects and promotion value in the processing of electric coupling iron parts.
In shipbuilding, chemical, petroleum, electric power and other industries, electric coupling iron parts need to withstand the test of various harsh environments. For example, in shipbuilding, electric coupling iron parts need to withstand the erosion of seawater and the vibration caused by ship movement; in the chemical industry, electric coupling iron parts need to withstand the erosion of corrosive gases and the influence of high temperature environments. These application scenarios fully demonstrate the advantages and practicality of the combined process of turning and milling composite processing and black oxidation treatment.
With the rapid development of modern industry and the continuous upgrading of manufacturing industry, the performance requirements for electric coupling iron parts are getting higher and higher. In order to meet these needs, we need to continuously optimize the process parameters and technical level of turning and milling composite processing and black oxidation treatment. For example, by improving tool materials and cutting parameters to improve processing efficiency and processing accuracy; by optimizing the composition of oxidation liquid and process conditions to improve the quality and performance of oxidation film. We also need to strengthen the performance testing and evaluation of electric coupling iron parts in harsh environments to ensure its reliability and stability in practical applications.
