摘要:
A cutting tap that has an elongate tap body with a fluted section at the axial forward end thereof wherein the fluted section includes a chamfered fluted section and a finishing fluted section. Each cutting thread in the chamfered fluted section has a cutting face disposed at a cutting face angle that becomes more negative the more axially rearward the cutting thread is from the axial forward end of the chamfered fluted section. Each cutting thread in the finishing fluted section has a cutting face disposed at a finishing cutting face angle that is essentially equal. The finishing cutting face angle is more negative than the cutting face angle for the cutting thread at the axial rearward termination of the chamfered fluted section.
摘要(中):
一种切割龙头,其具有在其轴向前端处具有带槽部分的细长的龙头本体,其中所述槽纹部分包括倒角的槽纹部分和精加工槽纹部分。 倒角凹槽部分中的每个切割线具有设置成切割面角度的切割面,该切割面变得比切割螺纹远离倒角槽纹部分的轴向前端更加轴向更靠后。 整理槽纹部分中的每个切割线具有以基本相等的精加工切割角度设置的切割面。 精加工切割面角度比切割螺纹在倒角凹槽部分的轴向后端处的切割面角度更负。
