Turning and milling composite machine tools are important equipment for modern precision machining. They integrate turning and milling functions. Through the high-precision CNC system to control the machining process, they can realize the machining of parts with complex shapes and high precision requirements. In the machining of large plunger copper sealing surfaces, the application of turning and milling composite machine tools is particularly important.

Turning and milling composite machine tools adopt advanced servo drive systems and precision guide rail structures to ensure the high rigidity and high precision of the machine tools. Through the precise control of the high-precision CNC system, real-time monitoring and adjustment of the machining process can be achieved to ensure that the flatness and surface roughness of the machined sealing surface meet the design requirements. Turning and milling composite machine tools also support the machining of multiple materials and multiple shapes, meeting the needs of customized plunger sealing surfaces.

The high-precision CNC system is the core of the turning and milling composite machine tool. It is responsible for controlling the motion trajectory, cutting parameters, etc. of the machine tool to ensure the stability and accuracy of the machining process. In the machining of large plunger copper sealing surfaces, the role of high-precision CNC systems is particularly prominent.

High-precision CNC systems can automatically generate processing paths and cutting strategies based on preset processing parameters and drawings. These parameters include cutting speed, feed speed, cutting depth, etc., which directly affect the quality of the processed sealing surface. By optimizing these parameters, the stability and efficiency of the processing process can be ensured.

High-precision CNC systems have real-time monitoring and adjustment functions. During the processing process, the CNC system can monitor the motion state and cutting parameters of the machine tool in real time. Once an abnormality or deviation is found, it will be adjusted immediately to ensure the continuity and accuracy of the processing process. This real-time monitoring and adjustment function is essential to ensure the high precision of the sealing surface.

In the processing of large plunger copper sealing surfaces, the control of cutting parameters is the key. Cutting parameters include cutting speed, feed speed, cutting depth, etc., which directly affect the generation of cutting force and heat. Excessive cutting force and heat will have an adverse effect on material properties, resulting in defects such as deformation and cracks on the sealing surface.

In order to avoid this situation, the cutting parameters need to be strictly controlled. The appropriate cutting speed and feed speed should be selected according to the material properties and processing requirements. For copper materials, due to its good thermal conductivity, a higher cutting speed can be selected; but at the same time, the influence of cutting depth should also be considered to avoid excessive cutting force caused by excessive cutting depth. The cutting parameters should be set in sections according to the processing path and cutting strategy to ensure the stability and uniformity of the entire processing process.

Appropriate cutting tools and cutting fluids should also be selected. The quality and precision of the cutting tools directly affect the quality of the processed sealing surface; while the cutting fluid can reduce the cutting temperature and cutting force, and improve the processing efficiency and quality.

In the processing of large plunger copper sealing surfaces, real-time monitoring and adjustment are important means to ensure processing quality. Through the real-time monitoring function of the high-precision CNC system, abnormal conditions in the processing process, such as excessive cutting force, excessive vibration, etc., can be discovered in time, and adjustments can be made immediately.

A complete monitoring system should be established to monitor the motion status and cutting parameters of the machine tool in real time. These monitoring data can be displayed in real time on the display screen of the CNC system, or remotely transmitted to the computer through the data transmission system for analysis and processing.

The processing parameters should be adjusted in time according to the monitoring data. Once abnormal conditions such as excessive cutting force or excessive vibration are found, the cutting speed or feed speed should be reduced immediately to reduce the cutting force and vibration. At the same time, the use of cutting tools and cutting fluids should be checked to ensure that they are in good working condition.

The machine tool should also be maintained and serviced regularly. This includes cleaning the cutting chips and oil stains inside the machine tool, checking the wear of the guide rails and lead screws, and adjusting the accuracy of the machine tool. These maintenance and care work can ensure the high precision and stability of the machine tool and provide a guarantee for the processing of high-quality sealing surfaces.

After the processing of the copper sealing surface of the large plunger is completed, quality control and inspection are required. Through advanced testing equipment and methods, the flatness, surface roughness, hardness and other indicators of the processed sealing surface are tested and evaluated. These test data can intuitively reflect the quality of the processing and provide a basis for subsequent improvement and optimization.

Appropriate testing equipment and methods should be selected. For the detection of flatness and surface roughness, high-precision testing equipment such as laser interferometers and optical profilers can be used; for the detection of hardness, special testing equipment such as hardness testers can be used. These testing equipments are highly accurate and reliable, and can ensure the accuracy of the test results.

The processing quality should be evaluated and improved based on the test results. Once quality problems or defective products are found, the causes should be analyzed and investigated immediately, and corresponding improvement measures should be taken. These improvement measures may include adjusting cutting parameters, replacing cutting tools, optimizing processing paths, etc. By continuously improving and optimizing the processing process, it can be ensured that the processed sealing surface has stable high precision and excellent performance.
