Faced with the demand for complex shapes, graphite extruded panels need to complete fine processing, which requires coordinated efforts from pre-preparation to processing technology and post-processing. First of all, in the processing preparation stage, accurate design planning is the basis. Using advanced computer-aided design software, a three-dimensional model is constructed according to the specific requirements of complex shapes. Through repeated scrutiny and optimization of the model, it is ensured that every detail meets the design standards and provides an accurate reference for subsequent processing. At the same time, according to the characteristics of the model, a detailed processing process is formulated to clarify the key points and precautions of each link, so that the processing process can proceed in an orderly manner.
The selection of processing equipment plays a key role in fine processing. According to the characteristics of graphite extruded panels, high-precision CNC machine tools are selected. This type of machine tool can realize multi-axis linkage. When processing complex shapes, the trajectory of the tool can be accurately controlled through the coordinated movement of each axis. Whether it is a curved contour or a special-shaped structure, CNC machine tools can ensure the accuracy of processing dimensions with their high positioning accuracy and repeated positioning accuracy. In addition, the rigidity and stability of the machine tool are also crucial. A stable machine tool can reduce vibration during processing, avoid processing errors caused by vibration, and ensure the processing accuracy and surface quality of graphite extruded panels.
The reasonable selection of tools also affects the processing effect. According to the hardness of graphite extruded panels and the complexity of the processed shape, select the appropriate tool material and tool type. For graphite extruded panels with higher hardness, carbide tools or diamond tools are used. These tools have good wear resistance and cutting performance, can remain sharp during processing, reduce tool wear, and improve processing efficiency. In terms of tool type, end mills, ball end mills, etc. are selected for different processing parts and shapes. Ball end mills are suitable for processing curved surfaces and can process smooth curved surface contours on graphite extruded panels with complex shapes; end mills are suitable for processing planes and straight grooves to ensure the dimensional accuracy of each plane and groove.
The optimization of processing parameters is an important part of achieving fine processing. Parameters such as cutting speed, feed rate and cutting depth are interrelated and need to be reasonably adjusted according to the material and processing shape of graphite extruded panels. Appropriately reducing the cutting speed can reduce the cutting force and avoid the graphite extruded panels from cracking or deforming due to excessive cutting force; reasonably controlling the feed rate can ensure the roughness of the processed surface and make the processed surface smoother; according to the complexity of the processed shape and the load-bearing capacity of the tool, choose the appropriate cutting depth to prevent the processing accuracy from being affected by cutting too deep. Through continuous debugging and optimization of these parameters, the best combination of processing parameters is found to achieve fine processing of complex shapes.
During the processing process, the choice of clamping method should not be ignored. Since graphite extruded panels are brittle, traditional clamping methods may cause damage to them. Therefore, special clamping methods such as vacuum adsorption clamping or elastic clamping are used. Vacuum adsorption clamping forms a vacuum on the workbench to firmly adsorb the graphite extruded panels on the workbench. This clamping method does not produce local pressure on the graphite extruded panels, avoiding clamping deformation. The elastic clamp clamping uses the elastic deformation of the clamp to evenly apply pressure to the graphite extruded panels, ensuring that the graphite extruded panels remain stable during processing, while reducing damage to their surface and ensuring processing accuracy.
Monitoring and adjustment during processing are the key to ensuring processing quality. During processing, online monitoring technology is used to monitor the processing size and surface quality in real time. Sensors and measuring instruments are used to measure the processing parts in real time, and the measurement data is compared with the design model. Once the processing error is found to be beyond the allowable range, the processing parameters or tool trajectory are adjusted immediately to correct the error in time. At the same time, the state of the graphite extruded panels during processing is observed, such as whether cracks or edge collapse occur. If problems are found, the processing is stopped in time, the causes are analyzed and corresponding measures are taken to avoid the expansion of the problem and ensure the processing accuracy and quality of complex shapes.
The post-processing process after processing further improves the processing quality. The graphite extruded panels are ground and polished to remove burrs and knife marks left during processing and make the surface smoother and flatter. For some complex shapes with special requirements, surface coating or chemical treatment may be required to enhance its surface performance. Through post-processing, not only can the appearance quality of graphite extruded panels be improved, but also its performance can be improved to meet various functional requirements under complex shape requirements, so that graphite extruded panels can play a better role in practical applications.
