卡克(又叫直角塞門或折断塞門)是机車車輛上用得很多的零件,它要求有很高的加工精度和光洁度,所以必須經过研磨。过去我厂研磨这类零件,都是由手工操作的,工人的技术要求很高,而生产效率又很低。为了解决这一关鍵問題,我厂曹根营同志根据多年的操作經驗,并經过长时期研究和試制,創造了一种比較完整的研磨机,用来代替手工操作。应用这种研磨机,使生产效率提高了40%,并且低等級的工人就能掌握。現将这研磨机的
Kac (also known as right-angle plug or broken plug) is a very much used parts of rolling stock, which requires a high degree of machining accuracy and finish, it must be ground. In the past I mill grinding these kinds of parts, are hand-operated, high-level technical requirements of workers, and production efficiency is very low. In order to solve this key issue, Comrade Cao Gen-ying of our factory has created a relatively complete grinding machine to replace the manual operation based on years of operating experience and after a long period of research and trial production. Using this grinder, the production efficiency is increased by 40%, and the lower level workers can grasp. Now this grinder
