朱兆金是浙江省余姚县人,原来只有小学六年级的文化水平。1953年进入上海一家工厂当学徒。社会主义改造高潮中,该厂并入中华铁工厂。1959年,中华铁工厂又和其他工厂合并,成立彭浦机器厂。就在这一年,他接连搞出了多刀多刃等二十多项刀具革新,一年完成了二年多的工作量。不久以后,他光荣地参加了中国共产党,并被评为上海市先进生产者。近几年来,他在党的培养教育和老师傅的帮助下,为了把厂内几百种不同规格的刀具都选用最合理、最先进的规格,并把它们分门别类地统一起来,进行定型,夜以继日地刻苦钻研业务,从生产实际出发,调查了厂内不同的机床情况,通过科学实验,设计了二百多种刀具,并编制了三册《定型刀具》和一册《专用刀具》技术资料,使全厂机床刀具切削效率提高一倍。去年,他被提拔为技师。下面我们请朱兆金同志着重讲讲,他是怎样通过科学实验取得这些成就的。——编者 Zhu Zhaojin is a native of Yuyao County, Zhejiang Province. It was originally only in the sixth grade of elementary school. In 1953, he was an apprentice at a factory in Shanghai. During the upsurge of socialist transformation, the plant was incorporated into the China Iron Works. In 1959, the Chinese ironworks merged with other factories to establish the Pengpu Machinery Plant. In the same year, he successively produced more than 20 cutting tool innovations such as multi-blade and multi-blade, and completed more than two years of work in one year. Not long afterwards, he honorably participated in the Communist Party of China and was named Shanghai’s advanced producer. In recent years, with the help of the party’s education and masters, he has chosen the most reasonable and most advanced specifications for the hundreds of different types of knives in the factory, and he has unified them into different types for finalization. Diligently diligently studied the business, proceeded from the actual production, investigated the different machine tools in the factory, and through scientific experiments, designed more than 200 kinds of cutting tools, and compiled three volumes of “Constructional Tools” and a “Special Tool” technical data. Double the cutting efficiency of the whole machine tool. Last year, he was promoted to a technician. Below we ask Comrade Zhu Zhaojin to focus on how he achieved these achievements through scientific experimentation. --editor
