1、 I 卧式镗铣床电气控制系统设计 摘 要 镗床是冷加工中使用比较普遍的设备它主要用于加工精度、光洁度要求 较高的孔以及各孔间的距离要求较为精确的零件（如一些箱体零件） ，属于 精 密机床。主要用于加工工件上的精密圆柱孔。这些孔的轴心线往往要求严 格 地平行或垂直，相互间的距离也要求很准确。因此，保证机床的精度至关 重要。 PLC（可编程控制器）作为一种工业控制微型计算机，它以其编程方便、 操作简单尤其是它的高可靠性等优点，在工业生产过程中得到了广泛的应用。 它应用大规模集成电路，微型机技术和通讯技术的发展成果，逐步形成了具 铣床控制 工业应用 有多种优点和微型，中型，大型，超大型等各种规格的系
2、列产品，应用 于从继电器控制系统到监控计算机之间的许多控制领域。 因此现在的机床控制设计以 PLC 模块为主，硬件电器元件为辅，可使接 线大为简化，不但安装十分方便而且工作可 靠、降低了故障率、减小了维修 量、提高了功效。 关键词：控制系统 PLC 镗铣床 工业应用 II Horizontal boring and milling machine elctric control system design Summary Boring is used in the manufacture of the equipment is widely used for its main machinin
