M7475平面磨床,是利用磁力将工件吸在工作台上进行加工的。加工完毕,工件已被磁化（尤其是轴承钢）,牢吸在工作台上。由于原设备中的退磁装置是由继电器组成,其效果和可靠性较差,退磁后,残磁仍很大,要取下工件,仍很费气力,劳动强度很大。 在厂党委领导下,全厂掀起了学大庆人,走大庆路,落实“鞍钢宪法”、大搞技术革新和技术革命的群众运动,1201连党支部遵照毛主席“破除迷信,解放思想”的伟大教导,组织了“三结合”革新小组,对该设备原退磁装置进行了大胆的改革。经过一个月的时间进行了20多次试验,终于试制成功可控硅退磁装置,效果良好。
M7475 surface grinder, is the use of magnetic suction to the workpiece on the table for processing. Processing is completed, the workpiece has been magnetized (especially bearing steel), prison smoking on the table. Since the demagnetizing device in the original equipment is composed of relays, the effect and the reliability are poor. After the demagnetization, the remanent magnetism is still very large. To remove the workpieces is still laborious and laborious. Under the leadership of the Party Committee of the Factory, the whole factory set off a mass movement to learn from the Daqing people, take Daqing Road, implement the “Anshan Iron and Steel Constitution,” and vigorously promote technological and technological revolutions. In accordance with Chairman Mao’s “break superstition and emancipate the mind” Great teaching, organized the “triple combination” innovation group, the device demagnetization device for a bold reform. After a month’s time for more than 20 trials, and finally successful trial SCR demagnetization device, the effect is good.
