1、毕业设计（论文）精密数控磨床的总体设计摘 要本课题是集机，电，液一体化的高科技项目，所要解决的关键问题是主轴箱上两个同轴轴承孔的超精密加工。此磨床的加工方式采用切入式磨削方式，工件安装在回转工作台上，随工作台回转，同时砂轮回转，砂轮的径向进给靠回转工作台沿X方向位移实现，上面的轴承孔及上端面加工好后，用同一砂轮加工下面的轴承孔及下端面，工件一次安装，以保证精度。总体布局为立式磨床，主要分为磨头部分、回转工作台、床身、垂直立柱、拖板以及测量机构。总体传动方案为：由外置步进电机驱动齿轮，然后通过齿轮
2、传动带动滚珠丝杠，整个磨头装置通过滚珠丝杠进行Z轴方向上的移动，磨头的旋转则通过另一个外置电机来驱动，回转工作台的驱动则通过外置电机驱动皮带轮，由皮带轮的传动来使回转工作台的旋转，拖板的驱动则由步进电机控制。同时，磨床的设计中运用了数控技术，现代测试手段，微量进给软件补偿技术，从而使精密机械设计达到所要求的精度。关键字：加工精度，设计方案，分配，参数42毕业设计（论文）精密数控磨床的总体设计GeneralDesignofPreciseNumericalControlGrindingMachineA
