Cutting Taps Pipe Threads Trouble Shooting
I am tapping pipe threads with a Taper Pipe Tap Rc(PT) on a machining center. I am worrying about Torn Surface Finish and Thread Chatter. Is there any improvement you can offer for this problem?
Try to change the tapping speed or RPM. You can improve the situation of the existing Torn Surface Finish and Thread Chatter by decreasing the cutting speed or RPM.
