我厂黄国强同志在万能磨床上,以每分钟两万转的高速干磨法磨削橡胶轴承,取得了从水磨每班三件到干磨每班三十五件优质高效的显著效果。它的特点是:(1)干胶屑呈粉状而不形成湿团,故容易排出;(2)干胶屑不象湿胶屑那样粘结砂轮表面,大大提高了磨削速度和磨削量;(3)高转速形成较大旋风自行冷却,不致产生高温引起的橡胶燃烧;(4)耗砂轮少,用水磨法磨十六件耗砂轮一个,而用干磨法磨四十五件,才用一个砂轮。
Our factory, Comrade Huang Guoqiang, grinds the rubber bearings with high speed dry grinding method of 20,000 revolutions per minute on the universal grinder, and achieves the remarkable effect of high quality and efficiency from three in water mill to thirty-five in dry grinding. Its features are: (1) Dry crumbs are powdery and do not form wet crumbs, so they are easy to expel. (2) Dry crumbs do not adhere to the surface of grinding wheels like wet crumbs, greatly increasing the grinding speed and grinding Volume; (3) the formation of a large high-speed cyclone self-cooling, will not produce high temperature caused by rubber combustion; (4) less consumption of grinding wheel, grinding water mill grinding wheel wear 16, , Only use a wheel.
