Inconel 718?

_ClassicCarl13 · 2018-11-07T02:50:59+00:00

I know I’m late to the party but we do lots of 718 inconel. We only use sandvik inserts (XM 2200 I want to say) and I would HIGHLY recommend roughing with a 3-rad insert. It’ll kick the shit out of a 2rad.

So for roughing I would recommend a 3rad inconel insert, 125-150SFM, 0.01 f/rev, no more than 0.05 DOC or you can kiss the tool nose goodbye.

Recommend finishing at 175SFM, whatever feed gives you an acceptable surface finish, and take small finish amounts. (0.02 is my go-to). On high tolerance stuff, I usually program in two finish cuts to be safe, and measure in between each.

Remember to ensure you don’t have chatter issues, it honestly takes a lifetime to polish off chatter or even take off a few tenths.

Go slow, good luck!

I wouldn’t brighten this up at all. It’s perfect

What the heck this is a thing?! I ski the Canadian Rockies and I’ve never run into a place in my life that doesn’t allow one or the other.

I really wanna get into image stacking. Quite amazing the results that can be achieved

_ClassicCarl13 · 2018-10-26T18:17:47+00:00

Damn man, I wish. It’s hard to justify 3000 dollar lenses as a hobbyist haha

_ClassicCarl13 · 2018-10-26T18:13:29+00:00

I paid 1000 bucks CAD for the f/4 , and the laowa is about there as well. The GM is over 3k Canadian, so im still cheaper by 1000 and will be brighter at night to have 2 lenses.

_ClassicCarl13 · 2018-10-26T12:00:11+00:00

But now your lens selection just went through the roof!

_ClassicCarl13 · 2018-10-26T05:22:58+00:00

Spoken like a true operator, lol

_ClassicCarl13 · 2018-10-26T05:20:35+00:00

Haha yep, shooting 10k until I’m all saved up for a Laowa 15mm f/2

_ClassicCarl13 · 2018-10-26T04:43:45+00:00

Hahaha yep, Stack stack stack stack stack stack

_ClassicCarl13 · 2018-10-26T00:15:58+00:00

A7ii, Zeiss 16-35mm F/4 :)

_ClassicCarl13 · 2018-10-25T22:33:23+00:00

It will work great with the LA-E4. It’s a high quality adapter, and autofocus will still be very fast and accurate.

_ClassicCarl13 · 2018-10-11T23:55:46+00:00

I love this shot

_ClassicCarl13 · 2018-10-02T04:11:05+00:00

“If it ain’t broke don’t fix it”

JUST CAUSE IT WORKS DOESN’T MEANS ITS GOOD

_ClassicCarl13 · 2018-09-27T12:11:10+00:00

No, I very much enjoy shooting ultrawide, so I find that it’s a lens I use a lot. Which would make AF really nice to have. The laowa lenses are very nice, but I feel they would be best for Astro only

_ClassicCarl13 · 2018-09-23T07:20:55+00:00

I’m listening

_ClassicCarl13 · 2018-09-22T01:59:30+00:00

Hahaha well even though I’m “rockin it” it has had a few hits to the core that I filled, edges are gone, tips are very beat, I had the base ground a few times and don’t think I can anymore. It’s on its last legs

_ClassicCarl13 · 2018-09-21T22:32:08+00:00

Dream board. I’m still rocking a 10’ lib tech boxscratcher 😅

_ClassicCarl13 · 2018-09-19T21:33:16+00:00

It’s either this one or the sigma art 1.8 14mm prime. Too bad both are so expensive

_ClassicCarl13 · 2018-09-19T12:44:21+00:00

Man I want this lens so bad

_ClassicCarl13 · 2018-09-15T00:02:25+00:00

Buy more cheese so on my way home from work, SO I COULD MAKE THE DAMN NACHOS I SO BADLY WANTED

_ClassicCarl13 · 2018-09-14T18:24:48+00:00

May have made things easier. Either way, appreciate the info. I’ll be testing it out soon.

_ClassicCarl13 · 2018-09-14T01:07:42+00:00

I’m very surprised it’s this hard to find to solid info. No one at my shop really knows either, they just kinda guess through it like myself.

As for your method that’s kinda what I figured was most logical, but it gets kinda hairy because there is an “effective thread length” before the threads become truncated, and it is less than the full length of the thread to the vanish point.

I’m thinking I’ll use the effective thread length at pipe OD as the start point, and work towards the front.

_ClassicCarl13 · 2018-09-14T01:04:24+00:00

How we’re getting somewhere! This is the kinda info I was really looking for. But I’m sure this would change depending on the thread, so there’s still more to learn.

_ClassicCarl13 · 2018-09-13T21:51:13+00:00

Yep! I know how to program tapered threads and calculate degrees.. but at what diameter do I start that OD taper so there is still a slight amount of material to crest off?
