一般切削刀具的材料多半采用碳素工具鋼、合金工具鋼、高速鋼以及硬质合金等。对于提高切削性能来讲,则以高速鋼及硬质合金为最好,但这两种材料都是很贵的。为了节省贵重的高速鋼和硬质合金,有的把它们先制成刀片,然后用钎焊或机械固定法鑲在刀杆上。但往往由于钎焊或固定方法不当,在切削过程中发生脱落现象。利用堆焊来进行刀具的生产是一种先进的方法,不仅有较大的经济价值,同时生产也比较简单。天津大学在这方面曾进行了一些研究工作,初步得出了 Most cutting tool materials used carbon tool steel, alloy tool steel, high-speed steel and cemented carbide. In terms of improving the cutting performance, the high-speed steel and hard alloy is the best, but both materials are very expensive. In order to save valuable high-speed steel and carbide, some of them first made of blades, and then brazing or mechanical fixation on the arbor. But often due to improper brazing or fixing methods, shedding occurred in the cutting process. The use of surfacing for tool production is an advanced method that not only has greater economic value, but also produces relatively simple. Tianjin University in this area have conducted some research work, initially came up
