Spark Machine processing oblique hole matching gap improvement plan production department: Xia Shengyi automobile mold date chapter oblique hole processing roundness matching gap tolerance requirement is 0 ~ 0. Between 005, the existing processing method is electrode turning processing by EDM three-axis Linkage Processing, processing dimensional accuracy in 0. 03 ~ 0. Between 1 (Ellipse), Can not meet the processing needs. First of all, let me analyze the conventional processing scheme :(Figure 1): Conventional processing methods: 1. Electrode Material: graphite electrodes are used for coarse Gong Jing Gong; 2. Electrode processing mode: the electrode is turned over and the side is processed separately; 3. Electrode machining accuracy: the step accuracy is 0. 03mm ~ 0. 1mm; 4. EDM processing mode: Multi-Axis linkage processing; 5. EDM machining accuracy results: roundness fit gap 0. 03 ~ 0. 05mm (Ellipse). Solution: optimize the electrode and processing method to improve the new processing scheme: 1. Electrode Material: graphite is used for coarse male and copper electrode is used for fine male; 2. Electrode processing mode: copper electrode cylindrical surface turning surface is processed and formed at one time; 3. Electrode machining accuracy: Step-free accuracy is 0. mm ~ 0. 015mm; 4. EDM processing method: C- axis multi-axis Linkage Processing 5. EDM machining accuracy results: roundness fit gap 0. 000 ~ 0. 005mm (Figure 2) As shown in the figure, the finishing electrode is changed from graphite to copper electrode, which can ensure the electrical precision of the date stamp of the automobile mold and meet the processing requirements. Summary: The conventional processing mode cannot guarantee the processing accuracy of 0 ~ 0. 005mm, how to ensure this machining accuracy? This problem forces EDM to change the processing mode. After the selection of electrode materials and the change of processing mode, this problem has been well solved, EDM has achieved a breakthrough in the processing difficulties of such structures of the same type and high precision.
