1964年6月,我把在生产实践中不断改进、不断摸索出的强力切断刀,参加厂举行的赛刀会。一般切断刀的两侧刀尖磨损快,生产效率低,于是改用屋脊式刀背,但两侧的刀尖磨损仍然较快。后来又磨出一个55～60°的刀尖角,解决了两侧刀尖的磨损问题。在党的关怀和工会的具体领导下,又参加了东北三市的赛刀会和全国先进刀具交流会,在很多有经验老师傅的热情帮助下,这把刀又得到了改进,使走刀量由0.09毫米/转提高到现在的0.52毫米/转。这把刀能在机床转速1200转/分、走刀量为0.50毫米/转的高速大走刀下进行切割工作。用它切断直径为50毫米的罗拉,50件只需要20分钟,而用一般
June 1964, I put in the continuous improvement in production practice, continue to explore the powerful cut off the knife to participate in the factory tournament will be held. General cutting knife on both sides of the knife fast wear and tear, low productivity, so switch to the ridge knife back, but both sides of the tip wear is still fast. Later, grinding out a 55 ~ 60 ° nib angle, to solve the problem of wear on both sides of the tip. Under the concrete leadership of the party’s care and trade union, he also took part in the tournament of the three cities in northeast China and the national exchange of advanced knives. With the help of many experienced masters, this knife has been further improved, The amount increased from 0.09 mm / rev to the present 0.52 mm / rev. The knife can be cut at a machine speed of 1200 rpm and a feed rate of 0.50 mm / rev at high speed. Use it to cut off a roller with a diameter of 50 mm, 50 pieces only take 20 minutes, and use it in general
