Copperweld钢铁公司依靠在严格的控制条件下加钙,创制了一种在高速切削时易于机械加工的特殊钢。钙具有促进切削的能力已为其他人所证明。但是,作为工业上的通用钢,经反复试验和用户初步试用,两者都确定其具有高的机械加工性能,这还是第一次。Copperweld公司对加钙改善机械加工性能的可能性进行了实质性的研究。日本曾对这个课题作了大量研究,并已在国内供应加钙处理的钢,但这种钢用作切削加工工件所得的数据很不稳定。经严格的实验室研究之后,
Copperweld Steel relies on the addition of calcium under stringent control conditions to create a special steel that is easily machinable at high speeds. The ability of calcium to promote cutting has been demonstrated by others. However, this is the first time that industrial grade general-purpose steels have been tested repeatedly and initially tried by users, both of which have been identified as having high machinability. Copperweld conducted a substantive study of the potential for calcium to improve machinability. Japan has done a great deal of research on this subject and has supplied domestic steel with calcium-treated steel. However, the data obtained from the use of such steel for the machining of workpieces is very unstable. After rigorous laboratory research,
