芜湖电工机械厂近两年来试生产了两种新型冲槽机,经上海电机厂、南京汽轮电机厂、无锡电机厂等使用,认为冲制的铁心片分度精度高,能解决特殊电机铁心片的加工,节省了可观的模具费。现将这两种冲槽机介绍如下: JA91-10型10t高速冲槽机:①采用了国外普遍应用的福开森分度系统,冲片分度精度很高。经试验,在φ990mm的冲片的φ800mm直径的圆周上冲槽误差仅为±0.06mm。冲片叠压后,此槽形孔 Wuhu Electric Machinery Plant in the past two years to trial production of two new slotting machine, the Shanghai Motor Factory, Nanjing Steam Turbine Motor Factory, Wuxi Motor Factory and other use, that the punching of the core tablets indexing accuracy, to solve the special motor core Film processing, saving considerable mold costs. Now these two kinds of notching machine introduced as follows: JA91-10 type 10t high-speed notching machine: ① The commonly used Fuk Fai-kun foreign system, punching sheeting indexing accuracy is high. The test, in φ990mm punching sheet φ800mm diameter on the circumference of the gash error of only ± 0.06mm. After lamination, the slotted hole
