摘要
文中使用电镀金刚石砂轮进行Al2024/SiCp复合材料小直径孔的磨削加工实验。实验结果表明,利用磨削方法对孔进行加工可以避免出现崩边和崩角缺陷,保证孔的完整;孔的入口和出口尺寸基本一致,孔直径略大于砂轮直径。孔壁的表面粗糙度较低,在实验所采用的加工参数条件下粗糙度在Ra0.347-0.578之间。
In the paper, the experimental study of grinding mini-hole of hole of Al 2024/SiCp composites with the electroplated diamond wheel was conducted. The results indicate that the breakage of work-piece in grinding machining can be effectively avoided. The roughness of holes is between Rα0.347μm and Rα0.578μm.
