Nice, no sense letting idle time go to waste.

glad you lost some skin and not a finger. Keep us updated on you works, looks good.

Interesting...I might have a proposition for you in the not-too-distant future.

That's freaking awesome!

Keep those digits out of the work plane.

What CAM software are you running? Or do you right your own code?

Sweet project.

Very cool.... Hhhhhmmmmmm.... now... what to make[Coffee]

If you want to get real nerdy, think up something for this TAIG unit i have.

Very cool! I'm still waiting on prices/tech to drop so I can get one of my mouthpieces CNC'ed in SST. But SST is so hard to work with it's cost prohibitive and is super hard on the tooling... one day though. Acoustical properties for a mpc would be great in SST.

Very cool! I would like to have a similar setup for Plasma cutting sheet metal..

Do you mean Ti? Stainless is relatively easy to work, any machinist worth their salt would be able to whip one out for you in short order I would think.. You will need some special tooling because of the shape but most larger shops will have some of that stuff laying around.

No sir, SST= Surgical Stainless Steel. Everyone I've talked to said it's hard on the tooling... or they are just too lazy to actually do it, lol. Got any names of shops I can talk to?

Thanks

Hmm, I'm not familiar with Surgical Stainless Steel. Do you know what alloy SST normally is? 4140, 4130, 416, 316L, 420, etc.. Once you know the alloy the hardness of the material is easy to figure out.
CNC tooling has come a long way since High Speed Steel was the standard.
Shoot skullybones a PM, he is a machinist. Not sure what his work load looks like but at the very least he will be able to give you some good advice and set you in the right direction.

Very cool. my man cave is in my garage so those wouldn't be issues for me.
Ill shoot you a PM after work, I would like to read more about that.

Think you could finish 80% receivers with that setup?

I have no clue... Will do at some point. Thanks

I would suspect that "Surgical Stainless Steel" is very much like "Aircraft Grade Aluminum"; kind of a misnomer. The aircraft industry specs a variety of different alloys for aluminum parts, just as the medical industry does with SS.

Any free machining SS like 303 should work just fine for you.

possibly this applies but it appears you are right and there are different types.

Most surgical equipment is made out of martensitic steel—it is much harder than austenitic steel, and easier to keep sharp. Depending on the type of equipment, the alloy recipe is varied slightly to get more sharpness or more strength.

Interesting, thanks for posting that up.

Most of the medical stuff we do at my work is non surgical.

Also should have put a disclaimer on my advice... I'm a welder, not a machinist so my knowledge on SS alloying is entry level-ish. I just work with a bunch of them :)

But anything less than that you have to sit there and watch the machine to make sure you don't eat a end mill. It is very interesting, if I mill too slow even on wood it will friction start a fire, but if I cut through with blazing speed it is not even warm to the touch. I think that the added hassle makes some machinists shy away from it for small one off production.

Right tool for the job definitely helps. SS can certainly eat tools if the Surface Footage is off. Machine rigidity is crucial as well.
The software only gets you so far. The principles you outlined make a project run a lot smoother when added to awesome CAM software.

I have always been intrigued by the home built equipment. Nice work.
