机床数控改装一般是指对现有机床做某些相应的改造,配上数控装置,从而使其获得数控加工的能力。在世界上,美国首先发展应用了数控技术,但在机床上的实用阶段是从数控改装开始的。最早期的数控改装,是在手动操作或仿形机床上,通过加装反馈装置、伺服驱动和能读出穿 CNC machine modification generally refers to the existing machine to do some of the appropriate transformation, coupled with numerical control device, so that it can get the ability of CNC machining. In the world, the United States first developed and applied numerical control technology, but the practical stage on the machine tool started with numerical control modification. The earliest CNC retrofit is in the manual operation or copying machine, through the installation of feedback device, servo drive and can read out
