摘要
针对C/SiC复合陶瓷材料加工过程中掉渣严重、螺牙成型困难、加工合格率较低等问题,通过大量的工艺试验,摸索出非金属材料小螺纹攻丝螺牙成型的变化规律,从工艺方案的确定、钻头材质的选择、丝锥材质的选择、丝锥攻丝受力等方面总结出在非金属纤维增强C/Si C陶瓷材料上的小螺纹孔攻丝的工艺加工方法。提高了非金属材料小螺纹孔攻丝的合格率。
Focusing on the problems of serious scaling-off, screw tooth forming difficulty, and low qualified rate in the machining process of C/Si C composite ceramics, massive experiments were conducted. Forming rules of small screw tooth of C/Si C composite ceramic material were found and processing technology of small screw hole tapping for the material was summarized from aspects of scheme, drill and tap material, and tap force. The qualified rate of small screw hole tapping of C/Si C composite ceramics was improved.
