电火花线切割机床是当前我国模具加工中必不可少的有效机床之一。但由于数控电气柜的制造工艺和元件(大多由分立元件及小规模集成电路组成)等等原因,当出现故障时,给正常使用和维修带来较大的困难。利用单板计算机——微处理机取代原数控电气柜来控制机床工作,是提高电气自动控制先进性的有效方法,尤其对于一些控制线路经常不稳定或不能正常工作的线切割机床,更能恢复生命力。 WEDM is one of the most effective machine tools in the current mold processing in our country. However, due to the manufacturing process of NC cabinet and components (mostly composed of discrete components and small scale integrated circuits) and so on, when a fault occurs, it brings great difficulties to normal use and maintenance. The use of veneer computer - microprocessor instead of the original CNC electrical cabinet to control the work of machine tools, is to improve the advanced automatic control of electrical methods, especially for some of the control lines often unstable or not working wire cutting machine to restore more vitality.
