In the field of graphite processing, the differences in processing performance between natural graphite and artificial graphite are significant, especially in the processing of micro - structures (such as grooves and sharp corners below 0.1mm). This article will focus on the pain points of graphite material processing and explain the entire process from CAD modeling optimization to CNC programming.
The physical property differences between natural and artificial graphite have a profound impact on cutting force and the risk of tool breakage. Natural graphite, with its relatively loose structure, is more brittle, leading to a higher risk of breakage during processing. In contrast, artificial graphite has a more uniform structure, which can withstand greater cutting forces. For example, in some processing plants, when using the same cutting parameters for natural graphite, the tool breakage rate can reach 30%, while for artificial graphite, it is only about 15%.
Different tool path strategies have different effects on graphite processing. The spiral plunge strategy is more suitable for graphite processing compared to the linear plunge strategy. The spiral plunge can gradually cut into the graphite, reducing the sudden impact on the tool and the graphite material. In a real - world case, a company used the spiral plunge strategy in graphite processing, which reduced the tool breakage rate by 40% compared to the linear plunge strategy. Figure 2 shows a comparison of the two tool path strategies:
When using the linear plunge strategy, the tool directly enters the graphite vertically, which can cause large cutting forces and increase the risk of tool breakage, especially in the processing of micro - structures. The spiral plunge strategy can effectively disperse the cutting force, improving the processing stability and the yield of finished products.
Vibration during graphite processing can seriously affect the processing accuracy and the quality of finished products. Introducing vibration suppression technology and the compensation function of the CNC system can effectively solve this problem. For example, by setting up shock - proof compensation in the CNC system, the vibration amplitude can be reduced by about 30%. The CNC system can also dynamically adjust the cutting parameters according to the actual processing situation to ensure the stability of the processing process.
Our GJ1417 CNC machine supports multi - axis linkage and dynamic compensation, which is very suitable for the processing of complex graphite structures. It can automatically adjust the cutting parameters according to the vibration situation during processing, improving the processing accuracy and the yield of finished products.
We provide practical parameter adjustment plans. For example, when processing natural graphite, reducing the cutting speed by 20% and increasing the feed rate by 10% can effectively reduce the cutting force and the risk of tool breakage. In a customer's case, after adjusting the parameters according to our plan, the processing efficiency increased by 30%, and the yield of finished products reached over 95%.
Maintaining process consistency is of great value in high - end application scenarios such as battery electrodes and mold electrodes. High - precision graphite parts can improve the performance and service life of products. For example, in the production of battery electrodes, high - precision graphite parts can increase the battery's charge - discharge efficiency by about 15%.
