Some cool Prototypes - Pics!

Interesting Russ (as usual, ho-hum) .
I'd be curious to know what amount of time the programming and set-up took.

Beautiful parts Russ. How does 303 SS machine?

I don't know Herrs from Haas, but that part looks like it needed sawing and a second op. Was it all done in a single setup from bar stock?

Very nice Russ (as usual)

Ed, 303 SS is a free cutting stainless steel - it machines beautifully and one doesn't have to worry about work hardening either. It also polishes very nicely.

A heck of a lot nicer than 304 does!



Impressive parts and finishes there Russ!

Hi Steve,

The programming time was in the neighborhood of maybe 30 minutes. From a programming standpoint, the part is simplistic, a reamed hole, a tapped hole, a milled radius, and an interpolated diameter.

The set-up time was around 20 minutes. Most of the tooling is already set-up all the time for most jobs anyways, so it was just a matter of putting in the correct sized drill and reamer.

The part is just held in the vise on parallels with a stop set up to locate it in the jaws, so nothing time consuming there as well.

First thing we did was stand the part on end in the vise and finish mill the .270" Minimum radius, the width, and drill and ream the thru hole.

The part was then flipped over and the holding stock milled off.

Next thing we did was set it in the vise to machine the post.

We roughed the post diameter (interpolated) to within .010" of finished size. The post tapped hole was completed next and the shoulder relief groove milled. Finally the post diameter was finish milled, and the sides of the shoulder rectangular surface chamfered.

Presto-Chango......we're done!

Best Regards,
Russ

Hi Ed,

303 machines very nice compared to other stainless steels. You just have to remember it is NOT steel, and cannot be treated as such with regard to speeds and feeds, DOC, WOC, and tool wear. Stick to the parameters dictated by the SFM of the material and the tooling being used to machine it and you should have no issues, unless working with longer flat pieces......there is a process you must follow to keep them flat, and it's making sure what ever you remove from one side you remove from the other otherwise it will bow like a son of a bitch!

Later,
Russ

Read my response to Steve.....it's all mentioned there.

Best Regards,
