1、拔销器零件加工装配摘　要本文介绍了拔销器各个零件的加工及装配的过程。通过对拔销器各个零件的工艺分析，加工方法的确定，以及装配工艺及装配过程的分析，介绍了工厂生产中三个步骤，装配件零件生产准备，数控加工和装配。众所周知良好的工艺是加工的前提，而只有通过零件图对加工工艺进行分析，进而确定加工方法，加工步骤，及加工路线，才能进行数控加工。数控加工就是要将被加工零件图样上的几何信息和工艺信息数字化，即编成零件程序，在加工程序单中的内容记录在磁盘等控制介质上，然后将该程序送入数控系统。数控系统则按照程序要求进

2、行相应的运算处理，然后发出控制命令，使各坐标轴、主轴以及辅助动作相互协调运动，实现刀具与工件的相对运动，自动完成零件的加工。而装配则是把许多零件连接和固定起来，成为各种组件、部件和整台产品的过程。工厂生产就是将这些过程有机的结合起来。关键词：拔销器，数控机床，工艺，装配-28-目录摘要········································································1一、绪论································
