编者的话:一年来,北京第一机床厂在工具研究所等兄弟单位帮助下,按照毛主席的教导,通过了实践、认识、再实践、再认识,摸到了硬质合金的一些规律,初步尝到了推广硬质合金的甜头。突破了硬质合金工具焊接、刃磨的两大关键;在车、刨、铣、铰、钻、刮、镗等刀具上分别推广了硬质合金,使得加工质量普编提高一级;平均单工序效率提高1～3倍;工具寿命提高2～4倍;硬质合金刀具推广面由25%扩大到50%。并且积累了推广硬质合金工作中政治工作、组织工作、技术工作、管理工作的一些经验。不久前,第一机械工业部在该厂召开了现场经验交流会,得到了到会代表们的好评,各厂代表纷纷表示要学一厂、赶一厂、超一厂。在推广硬质合金的活动中,比学赶帮超的热潮正在形成。为了促进这一活动的开展,现在把北京第一机床厂在推广硬质合金中取得的经验选择一部分发表。
Editor’s Note: In the past year, Beijing No.1 Machine Tool Plant, with the help of sister agencies such as the Tool Research Institute, passed the practice, understanding, practice and re-understanding of Mao Zedong’s teachings, touched some of the laws of cemented carbide and initially tasted To the promotion of the sweetness of cemented carbide. Break through the carbide welding tools, sharpening two key; in the car, planing, milling, hinges, drilling, scraping, boring and other tools were promoted carbide, making the general quality of the processing of a level; average single Process efficiency increased by 1 to 3 times; tool life increased by 2 to 4 times; carbide tool to promote the surface from 25% to 50%. And accumulated a promotion of cemented carbide work of political work, organizational work, technical work, management experience. Not long ago, the First Machinery Industry Department held an on-site exchange of experiences at the factory and was praised by all the delegates. Representatives of the factories all indicated that they should learn a factory, catch a factory and super factory. In the promotion of cemented carbide activities, more than academic rush to help the upsurge is taking shape. In order to promote this activity, now part of the experience gained by Beijing No.1 Machine Tool Plant in promoting cemented carbide is published.
