目前,国内高速钢刀具的钎焊,一般多采用焦炭炉和油炉加热。不仅劳动条件差,而且刀具质量也不稳定。我厂为了解决上述问题,从1978年起对高速钢车、刨刀采用了高频钎焊,收到了良好的效果。不但改善了劳动条件,提高了刀具质量,而且延长了使用寿命。仅以20×20毫米右偏车刀为例,过去加工JB113-60键2000个,需用20把刀具,其中掉尖的和不顶刃的较多。现在将油炉焊改为GP-100-C_3高频钎焊,刀具硬度普遍提高HRC2～3,掉尖现象很少。加工JB113-60键
At present, the domestic high-speed steel brazing tools, the general use of coke oven and oil furnace heating. Not only poor working conditions, but also the quality of the tool is not stable. I plant in order to solve the above problems, since 1978 on the high-speed steel cars, planing knife using high-frequency brazing, received good results. Not only improved working conditions, improved tool quality, and extended service life. Only 20 × 20mm right corner turning tool, for example, the past processing JB113-60 key 2000, the need to use 20 tools, of which the tip of the tip and not more. Now the oil furnace welding to GP-100-C_3 high-frequency brazing, tool hardness generally improve HRC2 ~ 3, the phenomenon of falling off rarely. Processing JB113-60 key
