M1380磨床虽然不是我公司重点关键设备,但却是公司几个冷加工分厂中唯一的大型外圆磨床,长期担负着繁重的生产任务,该设备运转是否正常对公司的生产有很大的影响。M1380磨床工件旋转驱动是直流发电机—电动机组,工作台运动是交磁放大机—电动机组,控制系统是中间继电器系统。发电机组噪声大、能耗高,是早就应该淘汰的装置;交磁放大机控制精度差,工作台运动时爬行,造成加工的工件表面质量差;该设备是20世纪70年代的产品,经过几十年的使用,线路老化、故障率高,
M1380 grinding machine is not the key equipment of our company, but it is the only large-scale cylindrical grinding machine in several cold processing factories of the company. It has long been shouldered with heavy production tasks. Whether this equipment operates normally has a great impact on the company’s production. M1380 grinding machine workpiece rotation drive is a DC generator - motor group, table motion is magnetic amplifier - motor group, the control system is an intermediate relay system. Generator noise, high energy consumption, is a device that should be eliminated long; AC magnetic amplifier control accuracy is poor, crawling when the workbench movement, resulting in the processing of the workpiece surface quality is poor; the device is the 20th century, 70’s products, after Decades of use, line aging, high failure rate,
