What are the ways of processing quality of carbon fiber auto parts?

(1) Formulate advanced standards for processing carbon fiber products. Carbon fiber processing standards determine the quality of carbon fiber products. Products made of carbon fiber are known to conduct electricity. So the quality of carbon fiber products. It is the design requirement of electrode connection position and the main factor of connection quality of electrode joint hole. The machining error of the outer diameter and thread diameter of the electrode in our country is larger than that in Japan and Soviet Union, and the machining accuracy requirement is lower. The machining error of the head taper of the graphite electrode cone in China is not expressly stipulated, so it is not appropriate, because the machining error of the taper of the conical thread is a very important data. If we ignore this point, even if the diameter of the joint and the electrode hole are qualified, abnormal phenomena will occur when the thread connection is used, and even various operational accidents will occur. Therefore, the establishment of advanced graphite electrode machining standards plays a leading role in the quality of carbon fiber auto parts electrode.
(2) Improve the level of process equipment Process equipment plays a key role in processing quality. First of all, it is necessary to improve the old center frame supporting electrode to process the thread of the electrode hole, to eliminate the increment of pitch, to prevent "chain buckle". Secondly, the old process sets the rotating datum surface of the workpiece on the circular arc surface of the center frame and the outer circle surface of the electrode with very poor accuracy. Due to the improper determination of the base surface, when the electrode appears ellipse, the electrode hole after processing also presents ellipse. Finally, it is necessary to improve the rigidity of ordinary machine tool processing graphite electrode equipment and its accessory devices, reduce the strong vibration of the machine tool clamping electrode rotation, in order to improve the processing accuracy of the electrode outer circle, end face and thread.
(3) Reasonable selection of cutting tools and cutting parameters is the fundamental way to improve machining quality. In our country, some manufacturers of cutting tools are too rough, lathe speed does not conform to requirements, it is difficult to ensure the processing accuracy of carbon fiber products. From the United States Ingersoll milling machine company introduced machine tools, electrode cutting parameters are an obvious feature of the workpiece speed is slow, small amount of cutting, milling thread with comb knife, exquisite technology. Therefore, to process high-precision finished electrodes, comb knives with high processing precision and high efficiency, rice milling cutter, or comb knives made of high-speed steel thread are selected to process joint threads. At the same time, constantly improve the grinding technology. The current grinding machine tool and grinding method often make the blade after grinding the height of the cutter, the uneven force when milling, causing the vibration of the milling cutter, seriously affect the surface of the thread roughness, the thread surface wave.
