End face wear of small brazed diamond grinding head for 3C ceramics

  • 摘要: 金刚石微铣磨头广泛用于3C产品的先进陶瓷构件加工中。通过对3C产品中最常用的氧化锆陶瓷工件进行磨削试验,观察钎焊金刚石微铣磨头磨损过程中的形貌演变,并统计氧化锆陶瓷的累计去除体积与磨头上金刚石磨粒磨损数量的对应关系,对比分析铜基和镍基钎料金刚石微铣磨头的磨损失效情况及寿命。结果表明:在相同加工参数条件下,铜基磨头的寿命较长,是镍基磨头寿命的1.2倍;在磨削过程中,金刚石磨头端面的磨粒存在破碎、磨平、脱落3种主要失效形式,且磨头的磨损主要从磨头端面边缘开始,逐步向其中心扩散,直至磨粒磨损严重而导致磨头失效。
