不锈钢和耐酸钢种类很多,基本上分为马氏体不锈钢、铁素体不锈耐酸钢和奥氏体耐酸钢等三大类。随着工业的发展,不锈、耐酸钢已广泛地被采用,特别是石油、化工工业应用这种材料更为常见。但由于这种材料存在着难加工(不好断屑)等方面的特点,因而成为钻削加工的“老大难”问题。对于这个问题,从前人们在生产中总是采取不同的做法。
Many types of stainless steel and acid-resistant steel, basically divided into martensitic stainless steel, ferritic stainless steel and austenitic acid-resistant steel, and other three categories. With the development of industry, stainless steel and acid-proof steel have been widely used, especially for petroleum and chemical industry. However, due to the existence of such material is difficult to process (not broken chip) and other aspects of the characteristics, and thus become the drilling “hard-won” issue. For this problem, people used to take different approaches in their production.
