高速鋼刀具在各个工厂中已經应用得很普遍。在过去,这种車刀的刀头和刀杆是用整塊高速鋼料鍛成的,因此高速鋼耗費很大。现在都采用鑲刃的方法,用高速鋼制造切削部分,用普通碳鋼做刀杆,这样便会节省許多貴重的高速鋼。高速鋼刀具鑲刃的方法絕大部分采用銅焊。但铜的熔点很低,刀具焊了之后不能进行淬火,因此刀具的硬度沒法提高,切削能力也受到了一定 High speed steel tools have found widespread use in various plants. In the past, the bits and rams of such turning tools were forged from a single piece of high-speed steel, so HSS was expensive. Now using the insert method, the cutting part made of high-speed steel, made of ordinary carbon steel arbor, it will save a lot of expensive high-speed steel. The majority of high-speed steel blade tooling method using brazing. But the melting point of copper is very low, the tool can not be quenched after welding, so the hardness of the tool can not be improved, cutting ability has also been certain
