摘要
针对氧化锆陶瓷钻削微孔过程中出现的轴向力大和出口崩边严重的问题,使用直径为0.2 mm的金刚石涂层钻头钻削完全烧结的氧化锆陶瓷微孔,通过单因素试验方法,研究主轴转速、进给速度和步进距离对轴向力的影响,在此基础上开展啄钻工艺对比试验,探索变进给啄钻工艺对出口崩边尺寸的影响。结果表明:轴向力大小随着进给速度和步进距离的增加而增大,随着主轴转速的增加先降低后增大;采用变进给啄钻可以有效提高孔出口加工质量。
In response to the problems of high axial force and severe edge collapse at the outlet during the drilling process of zirconia ceramics,a diamond coated drill bit with a diameter of 0.2 mm was used to drill fully sintered zirconia ceramic micropores.Through a single factor experimental method,the effects of spindle speed,feed speed,and step distance on axial force were studied.Based on this,a comparative experiment of pecking drilling technology was conducted,preliminary exploration was conducted on the influence of variable feed pecking drilling process on the size of outlet edge collapse.The results show that the axial force increases with the increase of feed speed and step distance,and first decreases and then increases with the increase of spindle speed.The use of variable feed pecking drilling can effectively improve the hole export processing quality.
