急!那位高人帮忙翻译下这篇小短文,不要机器翻译的

数控机床是数字控制机床的简称,是一种装有程序控制系统的自动化机床。该控制系统能够逻辑地处理具有控制编码或其他符号指令规定的程序,并将其译码,从而使机床动作并加工零件。
编辑本段数控机床的特点
数控机床的操作和监控全部在这个数控单元中完成,它是数控机床的大脑。与普通机床相比,数控机床有如下特点:
●加工精度高,具有稳定的加工质量;
●可进行多坐标的联动,能加工形状复杂的零件;
●加工零件改变时,一般只需要更改数控程序,可节省生产准备时间;
●机床本身的精度高、刚性大,可选择有利的加工用量,生产率高(一般为普通机床的3~5倍);
●机床自动化程度高,可以减轻劳动强度;
●对操作人员的素质要求较高,对维修人员的技术要求更高。
数控机床一般由下列几个部分组成:
●主机,他是数控机床的主题,包括机床身、立柱、主轴、进给机构等机械部件。他是用于完成各种切削加工的机械部件。
●数控装置,是数控机床的核心,包括硬件(印刷电路板、CRT显示器、键盒、纸带阅读机等)以及相应的软件,用于输入数字化的零件程序,并完成输入信息的存储、数据的变换、插补运算以及实现各种控制功能。
●驱动装置,他是数控机床执行机构的驱动部件,包括主轴驱动单元、进给单元、主轴电机及进给电机等。他在数控装置的控制下通过电气或电液伺服系统实现主轴和进给驱动。当几个进给联动时,可以完成定位、直线、平面曲线和空间曲线的加工。
●辅助装置,指数控机床的一些必要的配套部件,用以保证数控机床的运行,如冷却、排屑、润滑、照明、监测等。它包括液压和气动装置、排屑装置、交换工作台、数控转台和数控分度头,还包括刀具及监控检测装置等。
●编程及其他附属设备,可用来在机外进行零件的程序编制、存储等。
自从1952年美国麻省理工学院研制出世界上第一台数控机床以来,数控机床在制造工业,特别是在汽车、航空航天、以及军事工业中被广泛地应用,数控技术无论在硬件和软件方面,都有飞速发展。

CNC machine tools is referred to as the digital control machine tools, is equipped with an automated machine tool control system. The logic control system can handle control code or other symbols of the procedure provided for instruction, and decoding, so that the movement and processing machine parts.
Edit this paragraph of the characteristics of CNC machine tools
CNC machine tool operation and control in all of the NC in the modules, it is the brain of CNC machine tools. Compared with the general machine tools, CNC machine tools has the following characteristics:
● high-precision machining, with a stable processing quality;
● coordinates can be more linkage to the shape of processing complex parts;
● processing components change, only the general need to change the NC program, saving the production time;
● its own high precision machine tools, rigid, choose the amount of benefit processing, high-productivity (for the general machine tools in general three to five times);
● high degree of automation, machine tool, you can reduce the labor intensity;
● on the operators of higher quality, maintenance personnel on a higher technical requirements.
CNC machine tools in general by the following components:
● host, who is the subject of CNC machine tools, machine tools, including physical column, spindle, the feeding mechanism, such as machinery parts. He is used to complete the process of cutting all kinds of machinery parts.
● numerical control devices, is the core of CNC machine tools, including the hardware (printed circuit board, CRT monitors, key boxes, paper tape reader and so on) and the corresponding software for the digital input parts of the program, and completion of the input information storage , Data transformation, as well as a variety of computing interpolation control.
● drives, he is the executing agency of the NC machine tool drive components, including the main drive unit, feed unit, spindle motor and electrical feed, and so on. He's under the control of numerical control devices through the electric or electro-hydraulic servo system and into the main shaft to drive. When a number of joint feeding, can be positioned in a straight line, plane curve and the curve of space processing.
● assist device, index-controlled machine tools necessary supporting components to ensure the operation of CNC machine tools, such as cooling, Chip, lubrication, lighting, monitoring and so on. It consists of hydraulic and pneumatic devices, Chip device, the exchange platform, and the NC table CNC dividing head, cutting tools, including detection and monitoring devices.
● programming and other ancillary equipment can be used to drive in the outside part of the programming, storage and so on.
Since 1952, Massachusetts Institute of Technology developed the world's first CNC machine tools, CNC machine tools in the manufacturing industry, particularly in the automotive, aerospace, and military industry has been widely applied technologies in digital hardware and Software, are rapidly developing.
