我厂70年代从美国进口数控机床控制用的计算机是美国通用自动化公司生产的SPC16-60型工业计算机,其存贮系统是磁芯存贮器。经多年使用表明,磁芯存贮器工作性能不稳定,特别是在电源波动,外界干扰的情况下,存贮信息常有丢失,有时引起机床失控,因而机床故障率高。目前国外磁芯存贮器已淘汰,修板用的集成脉冲变压器等电子元器件也购不到。国内磁芯存贮器也已陆续为半导体存贮器所代替,因此,购板、修板十分困难,数控
I plant from the United States in the 1970s imported CNC machine tool control computer is the United States General Automation Corporation SPC16-60-type industrial computer, the storage system is the core memory. After years of use, it shows that the working performance of the magnetic core storage is unstable. Especially in the case of power fluctuation and outside interference, the stored information is often lost and the machine tool sometimes runs out of control, thus the machine failure rate is high. At present, foreign core storage has been eliminated, and the integrated pulse transformers and other electronic components used in the repair board can not be purchased. Domestic core memory has also been replaced by semiconductor memory, therefore, buy board, repair board is very difficult, CNC
