双头梯形内螺纹的加工,一般都是先车出一个导程,然后经分头再车出另一个导程,生产效率很低,还容易出废品。为此,我厂杨锡其师傅革新了一种双刀加工刀排,进行内螺纹开槽和半精车内螺纹,然后攻丝成形。经批量生产证明,效果很好,一般提高生产效率2～4倍,零件无废品,加工质量容易保证,操作也很简单。 Double-trapezoidal thread internal thread processing, are generally the first car out of a lead, and then pass another car another lead, the production efficiency is very low, but also easy to waste. To this end, my factory Yang Xi its master renovated a double-knife processing knife row, internal thread grooved and semi-fine car thread, and then tapping forming. The mass production certificate, the effect is very good, generally improve the production efficiency of 2 to 4 times, no scrap parts, processing quality is easy to ensure, the operation is also very simple.
