Parting Tool on Stainless Steel

[Omnimill]

I'm thinking I would like to make another flame eater but with a stainless steel cylinder next time. I'm pretty sure I would struggle to cut the cooling fins with my HSS parting tool but wondered whether a 2mm insert type would manage a 6mm plunge into some 303? This is the type I had in mind:

I only have a BV20 Lathe as well so it's not that pwerful ..

What do you guys reckon? I don't mind spending the money (too much :-\ ) as long as it works.

Vic, I'm still a newbie, and didn't know any better, so I parted off some ~5/8" diameter 303 stainless (with a 3/16" hole down the center), using a 5/64" (2 mm) wide HSS parting tool on my 7X12 lathe. No apparent damage to the parting tool or the lathe. I made sure the blade was sharp, turned it about half as fast as normal, fed it slowly, and used some cutting fluid. Don't have enough experience to recommend it, just reporting what worked for me...

Regards,
Rudy

Hello Omnimil

What is the benefit of a stainless flame eater cylinder?Just curious

 

[Omnimill]

Thanks Rudy, I've not knowingly turned 303 so maybe I should try it out with my old HSS parting tool before buying a tipped one.

Niels, I've just got a new flame eater plan from Jan Ridders and Stainless steel is specified for the cylinder this time. :-\

On the other side, parting with a tipped tool is quite pleasant. And the tips will last very long unless you misuse them.

I would always prefer a tipped parting tool because the geometry of the blade is always fix and you don't have to worry about how to grind it.
