人们从一般的技术观点出发,经常抱怨数控机床使用得太少。就是在一些大企业里,将数控机床大量地用作为加工设备,也还是少见的。只有那些本身经营控制设备的电子行业和航空工业,倒有相当多的工厂可以算是例外。不计较经济效益而侈谈添置数控机床以支持技术发展的种种努力,并没有什么效果,这是因为用户必须更多地考虑机床的经济性。举例来说,虽然一台简单的主轴可调多轴钻床需要较长的调整时间,但往往也比一台数控机床来得经济 People from the general technical point of view, often complain about the use of CNC machine tools too little. It is in some large enterprises, the large number of CNC machine tools used as processing equipment, is still rare. Only those who operate their own control equipment in the electronics industry and the aviation industry, a considerable number of factories can be regarded as an exception. Regardless of economic benefits and talked about the purchase of CNC machine tools to support technological development efforts and no effect, because the user must consider more economic machine. For example, although a simple spindle-adjustable multi-axis drilling machine requires a long adjustment time, it is often more economical than a CNC machine
