303 & 304 Stainless Steel Lathe Speeds & Feeds! WW204

Показать описание

Turning Stainless 303 & 304 with Paul Debolt. A continuation of our other Turning Steel video, let's talk inserts, speeds & feeds, and make some chips! First, we'll ease our way in with 303 and then take on the challenge of 304. We'll try different S&F as well as different types of inserts to see how they affect the cuts.

I really love these videos with Paul Debolt! He's a wealth of knowledge for those of us doing hobby work on hobby machines. Please go back for more, and thank you!

I cut almost all 304 stainless on my CNC lathe for my product. I wish when I was getting into it I had a mentor for practical advise. The biggest advice I could give to someone wanting to cut a lot of 304 is....buy quality inserts. I'm using almost all Sandvik now. It seems really expensive getting into it, but you can find good deals out there, and even at the bulk price of $100/pack, it's actually cheaper in the long run...a single insert would probably do what most people really need for a long time. eBay is a great place to get 1 or 2 inserts as a trial.

I wish the tooling vendor was a silver bullet answer, but I can't get one to help me out...it's likely different if you're a big shop. When I was having problems with my face grooving, the only way was to push through myself and try out a bunch of tools, inserts and grinding my own reliefs. Eventually I figured out how to do it, but it's not an easy operation in 304 in my opinion. Many of the speed/feed recommendations online all apply to simple turning as we saw here in the video, problems are almost always on the challenging operations like mentioned, or threading or some other cut that doesn't go as planned.

Paul's the man! My favourite videos of yours are the ones you've done with him, and that's not a knock on your regular videos, he's just that good!

As an Instrumentmaker using manual machines on all the hard to machine materials whenever possible on the lathe I used coolant, I made all kinds of shields to contain it, on the Bridgeport mill I bought a cold air gun that worked fantastic. This way you can always get an accurate measurement when your workpiece is not hot.

Thanks to both of you for doing this. There is probably 4 hours of work noted and edited down to 20 minutes. Very helpful. Thanks again

...I'm a beginner hobbyist but the generosity of knowledge here is much appreciated. Thanks.

I was thoroughly entertained - great video!

Been waiting for this vid for a long time! Thanks for going back to finish up the series, really enjoy Pual's insight. Would have liked to see to see 17-4 only because I've never been able to break that chip with anything under about 20 thou feed.

Love this kind of stuff! Thanks for the great effort you put into providing this stuff.

Awesome episode. These videos with Paul are my absolute favorite. He has so much knowledge about machining

I’ve owned a 7” and a 10” and neither were good for me. Stepped up to a 13” and would never consider anything smaller. Just the mere accuracy of a larger machine is night and day. Next one will be a 16”. Paul makes some great observations. As far as turning 304 I’ve been avoiding it for some time and have had trouble sourcing the diameters I need in 17-4 or 4140 and find myself back to 304 hence why I am watching this video. Problem is we’re talking 7mm round bar and deflection is a real issue for me. I’m going to give it a try and see how it runs. Also I’ve not had any luck with expensive cbn inserts. They always seem to have limited life and carbide inserts have worked well in stainless for me at least lasting through a few jobs. You know when heat transfers to the chips well when one lands on you and sinks into your forearm :-).
