求翻译：工作台是许多机电一体化中的一个不可或缺的基本部件，我所做的本课题是数控龙门铣床的工作台设计，它由导轨座、滑块、工作台、滚珠丝杆螺母副、伺服电机等部件组成。滚珠丝杆是将回转运动转化为直线运动，或将直线运动转化为回转运动的理想的产品。滚珠丝杆由螺杆、螺母和滚珠组成。它的功能是将旋转运动转化成直线运动。数控龙门铣床工作台工作的原理是：通过执行元件伺服电机的运转驱动滚珠丝杆，滚珠丝杆螺母副带动滑块和工作台在导轨上运动，完成工作台的直线往复运动。导轨副、滚珠丝杆螺母副和伺服电机均已标准化，设计时只需根据工作载荷选取即可。是什么意思？

It is one of many mechanical and electrical integration, one of the indispensable basic parts, I do not do this topic is one that is the goal of the milling CNC table design, it is the guide, slide, a working desk, ball-screw nut, servo motor, and parts. ball-screw is the swivel movement into a line

Table is an integral part of many mechanical and electrical integration, I did this project is the design of NC milling table, it consists of guides, sliders, table, ball screw and nut, servo motors and other components. Ball bearing silk pole is to convert rotary motion into linear motion, or ideal
