一、前言带锯下料生产效率高,切口平直省料,是现代机械工业中最先进的锯切工具之一。目前,一些工业技术先进的国家如美国、日本等,正在广泛应用双金属带锯。双金属带锯是以高速钢为齿部材料,以弹簧钢为背部材料,利用真空电子束焊接到一起,然后经过一系列冷加工及热处理后制成的锯切工具。由于它兼有高速钢的优良切削性能和弹簧钢理想的弹性、韧性,可用于锯
First, the foreword Band Saw Cutting production efficiency, cutting straight and save material, is one of the most advanced sawing tools in the modern machinery industry. At present, some advanced industrial countries such as the United States, Japan, are widely used bimetal band saw. Bimetallic band saw is a high-speed steel for the tooth material to spring steel for the back material, the use of vacuum electron beam welding together, and then after a series of cold and heat treatment made of sawing tools. Because it combines the excellent high-speed steel cutting performance and spring steel ideal flexibility, toughness, can be used for sawing
