南京无线电元件三厂在国内首次革新成功电位器研磨工艺,使电位器产品一次合格率达到98.8％,工效提高近40倍。电位器旋转接触片表面由于原材料工艺技术不高,一般都有高低不平的波浪形纹路,因此,使用时手感不好,旋转会产生压力“跳跃”现象和“沙沙”响声,影响产品寿命和使用效果。南京无线电元件三厂组织攻关,经一年多努力,革新成功用球形离心机添加研磨溶剂研磨接触片工艺。用这种工 Nanjing radio components factory in the country for the first time successful innovation Potentiometer grinding process, so that a pass rate of the potentiometer products reached 98.8%, work efficiency increased nearly 40 times. Potentiometer rotating contact surface due to raw materials, technology is not high, generally rugged wavy lines, therefore, feel bad when used, rotation will produce pressure “jump” phenomenon and “rustling” sound, affecting product life and use effect. Nanjing radio components plant research organizations, after more than a year of hard work, the success of spherical centrifuge added grinding solvent grinding contact process. Use this kind of work
