I have a customer needing approximately 400pc 3/4" NC blind threaded holes 5/8" deep in 3/4" Hastelloy
C276 plate.
Machine shops in Shreveport area are scared of this job.
Any help is greatly appreciated.
Wish Titan would demonstrate how easy it really is :).
It can be done, something that Walker-Wheland would have tackled back in the day in Shreveport. I do have some concerns. 3/4 thick plate, blind hole 3/4-10 x 5/8 deep, with a thread mill sized for 10 TPI, the insert would be .100" wide min. so flat bottom of hole would leave a .075" thick wall on bottom of the plate. Did I envision that correctly. Not much wiggle room :D, I would be concerned about bottom of hole work hardening being so thin, possibly blistering out a little in the bottom of the plate.

The best advice I can offer is contact your local tool Rep Give them your information on what your cutting, machine and its capabilities spindle rpm reagitity…
They should be able to see you through to the finish.
Drill & or mill to max acceptable diameter. Then. Thread mill to size.
Trying find a shop to tackle it. Nobody will.
I’m a small full manual job shop.
Any ideas on a shop would do it?
Thanks, Jimbo
Are yall interested? Make a video of it. Even tool reps are scared of this one.

@JimboBaker RFQs are not allowed. This is for lurning. As for getting the job done you might have to pass on it.the customer will ether have to change thete design or look somewhere else to get the job done
Good Morning! Bottom side of plate gets polished. As long as we do not break through everything is ok.
Sorry for slow response. I just saw your message in spam folder.
My Uncle used to have a Tool and Die shop directly across the street from Walker Wheland years ago before they both closed.
Even local tool reps are scared of this job.
Thanks, Jimbo
I had hoped you knew David. He and I did a lot of jobs together. When I worked at Sunbeam, we used his shop for new and repair of molds, when I worked for Premier Molding, we used his shop for same and at Walker-Wheland we made items for him. Accu-Tech and WW were top of line shops back in eighties and nineties.
He was an awesome, well respected man. I miss him greatly. Best Uncle Ever. I was always intrigued by the tool and die work he did. It was so much different from an Oilfield repair job shop like I am.
But we have survived when most shops didn’t. Been in business since mid 1970s.
Thanks, Jimbo
