一、换新碳刷快速精磨的方法目前我厂生产线上的几种变流机,都是既有直流碳刷又有交流碳刷,其数量每台少则几块,多则十几块。由于种种原因造成有报废碳刷的现象,须换新的。按工艺要求,碳刷的精磨程度必须在95％以上,而订货方往往要求百分之百。为此,即使配端盖粗磨碳刷,要达到精磨程度至少得8小时以上的精磨时间,而出厂前的电机转动时间长了对电机寿命不利或会影响生产进度。因此,我们总结出一个快速精磨的办法,一般几十分钟至一个多小时即 First, the new carbon brush fast grinding method Currently, I plant several production lines on the converter, are both DC brush and AC brush, the number of each as few as a few, as many as a dozen . Due to various reasons, scrapped carbon brushes have to be replaced. According to process requirements, carbon brush grinding degree must be above 95%, while the order side often require one hundred percent. To this end, even with coarse carbon brush cap, to achieve the degree of refining at least 8 hours or more grinding time, while the motor before the factory a long rotation of the motor life or adversely affect the progress of production. Therefore, we summarize a fast grinding method, usually tens of minutes to more than an hour
