Stainless Die Plate

[RickG]

Okay I have a question ...

 

When you are working with a piece of stainless plate that is 3 X 6.5 X 53.5 and you have to cut several slots and contours into it. Is it better to rough it in, then anneal/stress relive or do you do it before you even start?

 

It has 20 slots that go thru and the countours match with the back side going about half way thru. The ends are also cut down to about .6 thick ... must be for mounting. The slots are bunched up in the middle of the plate using the center 36.0.

 

So do I anneal first? or rough first?

Ruff First ! and also talk to your HT source and he can guide you on what it will do at HT.

Want us to water jet it ?

Rick, we usually anneal our stainless first as bar stock. But it gets used for various jobs and there isn't time to do it when the job is running.

I would anneal first although the stress imparted through workpiece clamping will likely present the biggest challenge. You're sort of in between a rock and a hard place with this task.

+1.

BTW, what stainless are you using?

Well they gave me a piece of 304 that has been flame cut to both length and width ... over size of course.

We are planning on roughing down the edges on a boring mill then cutting undersize slots .. we'll probably anneal it then before we start finishing ... If it looks bad (twisted) as i get closer to finish I may do it again.

If material is 300 series I always rough fisrt

(because 300 is gummy and moves easily.)

If 400 or PH series I stress first because its

easier to control. Thats just me.
