在机床的装配过程中,研与刮是一种劳动强度很高的工作,如在研合龙门刨垂直架塞铁时,过去需要有两个工人费力地往返推动。后经我厂装配车间刀架小组工人刘富宽同志与小组同志们共同研究,利用简单的杠杆原理,创造了一个研塞铁的工具(如图)。目前只要一个人就能较轻快地研合塞铁。 During assembly of the machine tool, grinding and scraping is a labor-intensive task. For example, when working on a vertical cambered iron with a gantry, it used to require two workers to push back and forth effortlessly. After I plant assembly workshop tool holder group comrades Liu Fukuan and group comrades together to study the use of simple lever principle to create a tool for grinding iron plug (pictured). At present, only one person will be able to study the slug lighter.
