螺纹铣刀攻丝是目前加工内螺纹最通用的加工方法。然而，由于攻丝属于封闭式加工，产生的切削力大、切屑多，因而散热排屑条件均差，经常出现丝锥崩刃和断裂，尤其是加工难加工材料如铬镍铁合金、耐盐酸镍基合金（Ｈａｓｔｅｌｌｅｙ）及钛合金等，加工效果更差。为解决这... Thread cutter tapping is currently processing the most common thread processing methods. However, tapping is a closed process, resulting in a large cutting force, more chips, so the heat removal of chip conditions are poor, often tap chipping and fracture, especially the processing of refractory materials such as inconel, nickel chloride resistant base Alloy (Hastelley) and titanium alloy, the processing effect is even worse. To solve this ...
