现阶段我国机械制造业迅猛发展,以现代化的电子、自动化技术日益成熟,数控机床技术在生产中应用越来越广泛,数控机床在结构形式上出现了多样化、智能化、复杂化,数控机床的故障也随之而来,故障的诊断技术已成为生产中重要的一门技术。因此,必须要对数控机床故障的诊断、维修引起重视,使数控机床更好的发挥在生产中的作用。 At this stage, the rapid development of China’s machinery manufacturing industry, with modern electronics and automation technology is becoming more sophisticated, CNC machine tools technology is more widely used in the production of CNC machine tools in the structure of the emergence of a variety, intelligent, complex, CNC machine tools The fault also comes along, fault diagnosis technology has become an important production technology. Therefore, we must pay attention to the diagnosis and maintenance of the CNC machine tool failure so that the CNC machine tool can play a better role in the production.
