在上海重工业妙会上,有一把利用报废齿条铣刀改成的刨刀(见下图)。它的前角为10°,在加工中碳钢零件时,切削速度为17公尺/分,吃刀深度为3公厘,走刀量达一公厘,效果很好。这种铣刀虽然已报废,但在刨削工作却发挥了它具大的作用。废铣刀再显神通@东锋 At the Shanghai Heavy Industry Fair, there was a planing knife that was replaced with a scrap gear milling cutter (see below). Its rake angle is 10 °. When machining carbon steel parts, the cutting speed is 17 m / min, the cutting depth is 3 mm, the cutting distance is 1 mm, and the effect is very good. Although this cutter has been scrapped, but in the shaving work has played a big role. Abandoned mills again fantastic @ East front
