End mills.

552 minutes of time in the cut so far cutting 304 SST at 2800 rpm 8ipm. .213 DOC then .003 fin. Cutting in a fixture with only tail stock pressure holding it(not a lot of rigidity). I love not spending money on tools.:hehe:

Yike! I wish we got that kind of tool life! Pocketing C1018 of all things has brought on some challenges I never saw coming. I try to stay in Aluminum whenever possible.
Who do you use for tooling Ron? |
End mills.
Ron, two flutes on stainless?
Who's tooling? |
Hanita 3 flute coated with .018 radius. Looks the same under the microscope when I finished the job a few minutes ago as it did 3 days and 175 parts ago.

What would a bit like that cost, I know nothing of machining just curious.
|
A lot of factors play into end mill pricing. We use 3/8 end mills for a majority of our stuff and they range from $40 a piece up to $100. Some of the more exotic end mills and custom ground mills can be upwards of $300 depending on size.
That feed rate override is all fun and games until you forget about it and watch your $100 end mill plow through something way quicker than you anticipated LOL |

Especially on the lathe. 90%+ of what I do is stainless steel, with lots of welds being machined off. Front sections are 1.375 dia x any where from 2.5 to 9" long and can have as many as 96 welds each. Very hard on insert tools. |

Actually, it's a piece of cake with solid way machines and good tooling. With a linear guide machine it would be hell, and I'd be getting Christmas Cards from MSC.

4 orders like this so far. Probably make at least another one as well.

love it. Production work is the most satisfying thing there is.

On a mill 304 is not bad machining, on lathe it's crap, real sticky.
Have you done any interrupted cuts on your late with carbide inserts, they don't like it. |
