简易数控机床是用微机控制装置对各种机床进行改装而成的一种经济型开环式数控机床。它与全机能数控机床相比较,没有自动识别物件位置(如刀具位、工件位置)的控制系统和信息反馈自动补偿的闭环控制系统,这就使得机床结构大为简化,价格也大为降低。加工精度和加工效率要低一些,它的功能相当于全机能数控机床的60%。目前,一台全机能的数控机床价格约为20万～ Simple CNC machine tool is a microcomputer control device for a variety of machine tools made of an economic open-loop CNC machine tools. Compared with full-function CNC machine tools, it does not automatically recognize the position of the object (such as tool position, workpiece position) control system and information feedback automatic compensation closed-loop control system, which makes the machine structure is greatly simplified, the price is greatly reduced. Processing accuracy and processing efficiency is lower, its function is equivalent to full-function CNC machine tools 60%. At present, a full-function CNC machine tool price is about 200,000 ~
