Title: Help please (pipe threading)
Post by: Noitoen on May 12, 2017, 09:21:46 AM
I wonder if someone can help me. Some time ago I saw (can't remember where) a guy that had a sort of cnc to open pipe threads. It used a small angle grinder mounted on a X/Y fixture next to an hand cranked chuck that automatically advanced the pitch to cut the thread with a milling disc.

I've tried everywhere to find it again without any luck.

Maybe this was the controller used. I remember it was a small table top portable unit that was hand cranked with only the X/Y axis moving the grinder with the cutting blade.

An American pipe thread has a full-taper of 3.5798.  The gauge diameter and depth varies with each size of pipe thread.  There are tapered reamers for finishing a pilot hole to diameter and taper.  ???
