我厂伞齿轮刨床工人先进生产者陈宝珍同志敢想敢干改进标准刨刀,使生产效率提高一倍,刀具的耐用度提高了5～6倍,取得了显著的效果。陈宝珍同志在工作中注意到原来使用的刨刀,因为前角太小,切屑变形太大,消耗的马力也大。更由于刀尖没有圆弧,散热不良,刀具使用寿命很低。据上述情况,经过努力钻研和多次试验,在粗刨伞齿轮时,采用了如附 Our factory bevel gear planer advanced production workers Comrade Chen Baozhen dare to dare to improve the standard planing knife, so that productivity doubled, the durability of the tool increased by 5 to 6 times, and achieved remarkable results. Comrade Chen Baozhen noticed in the work of the original use of the planer, because the anterior horn is too small, the chip deformation is too large, the horsepower consumed is also large. More because the tip does not arc, poor heat dissipation, tool life is very low. According to the above situation, after hard study and many tests, rough sharpening bevel gear, as adopted
