Hey guys.
We are running some SS parts.
12 holes each, Rigid tapped.
10-24 .75 deep.
We are spoting then drilling 0.158 diameter.
We are drilling to about 1.0 inch.
This is mystery stainless BTW. So im going to assume 304.
Tapping at about 300 rpm.
Breaking taps left and right.
We tap to .375 once all the way around. Then tap again to .75
When we tap to .75 the taps are breaking.
So i wanted to try a peck tap cycle. But i cant find one in our machines manual.
We have peck drilling. just no peck tapping. Thats why i tap to .375 all the way around the B.c then again to .75.
I have done this before without any problems. But today we broke 3 taps already.
Can someone help ?
What is the normal peck tapping cycle ? Maybe i can find it.
We use tapping fluid and all that.
Im at a loss. please someone.
