Idler Axle | CNC Lathe Machining | KENNAMETAL FIX8

[@jimurrata6785]

That FIX8 sure can move a lot of metal! Like the old Timex* ads with Cameron Swayze "It takes a licking and keeps on ticking"

[@paulbennett6379]

It's a skill by itself just reading that drawing,,good work Chris

[@crazymtbrider]

I came to see chips fly and wasn't disappointed your rough cut at 10mm is better than my finish cut on the hobby lathe 👍

[@johnlawler1626]

Made a good few of them wheel bogey shafts back in the day but they didn't have keyway,wish I had that kenametal tool then it would have made short work of it👍great video thanks for sharing 👍 ps sound was OK for me

[@ChrisMaj]

Yeah, that tool is a beast.

lovely work as always mate.. great stuff

[@pippy4658]

That fix8 is an absolute beast!!!

[@ChrisMaj]

But I still like my good old CNMG644 😉

[@elijahgreenberg2634]

Oh boy, I've been working on some Haas machines for the past year, and let me tell you, I *miss* the Fanuc control from the Doosans I worked on last year. Very satisfying cuts!

[@mystiquesquared]

You guys do some great work over there. Looking like complete studs.

[@BruceBoschek]

DOC 8.89 mm! Wow. Man, that FIX8PCJNR is a real mean cutter and the TNMG certainly gives a fine surface. This was a really fantastic video, Chris! Thanks so much. I really enjoyed it (even if I did get a bit nervous watching that shaft go into that hot wheel!). 🙂

[@urbanwillis2212]

I don't know where you work, but you have the most interesting job in America. I would like to just be a helper/swamper in that shop to operate the crane and move iron. But, at 77 I am a has-been and between you and the other great KZbin folks give me some relief of old age boredom. Thanks and keep up the great videos. And insert tooling has really improved the tool reliability and service life. You are awarded one "Atta Boy."

[@seimela]

I don't think he is in USA

[@ChrisMaj]

I'm in the Chicago suburbs. I think our shop is still way behind with all that fancy tooling, but the boss is like old school, but we are doing OK.

[@ChrisMaj]

@seimela yes, I'm in the US, my friend.

[@willpestka2745]

@@ChrisMaj Trust me, latest and greatest is not always the best solution. At the shop I work at we have 6 manual lathes turning all day handling repairs and simpler new parts. All other new ones are CNC. In most cases of repair work, it is faster and more reliable to machine on a manual.

[@larryblount3358]

Thanks for showing the times for the steps. I have always been curious.

[@localele1]

I like the roughing times shown as well.Puts it in perspective for those of us who make tiny parts on small lathes.

[@pcpkits5330]

insane inserts for roughing!

[@ChrisMaj]

I think it's time for a new phone cause the sound is acting up in my videos. I was thinking about getting a camera, but it just won't work in my case. I have to figure out something.

[@madaxe79]

you can get microphones that plug into your phone, and depending on what phone you have, you can get lenses too.

[@ChrisMaj]

@madaxe79 The thing is that all my videos are recorded while I'm working. I really don't have the time to play around with microphones. Sounds like the audio is shifted to the left side only.

[@madaxe79]

@@ChrisMaj Yeah I'm hearing you. I try to record when I'm working and it just doesn't work for me. I have so much video that is basically scrap because of the quality. I bought a little clip on lens kit and a microphone, but with the work I do, I have such little time usually, so I can never get it setup in time. the the lens kit always gets foggy from the humidity. I have filmed a video about my milling machine controller conversion, 3 times, and I've scrapped it all because the audio is no good. the microphone is kinda OK, but it picks up on every sound, so if there's someone welding or using a grinder or hammer at the other end of the building, it comes through really load. It's something I'm trying to figure out too, so I can build a channel.

[@TheMetalButcher]

@@ChrisMaj Chris, it doesn't matter much for machining. You can just set the audio to mono to hear it on both sides. I didn't notice a difference.

[@ronferguson9695]

Lpp😊😊 4:48 hours 4:48

[@davidpook5778]

That FIX8 is impressive!

[@currentbatches6205]

1:19 - Don't recall you taking that amount per cut, but this is a medium-carbon alloy. 1:41 - Gonna copy that chip guard. 1:52 - Like getting slag from a cutting torch in your shoe! 3:43 - Someone with good data analysis could determine the DOC from the increased RPM. Ferrari analyzed the gear ratios of opposing F1 race teams some years back using similar technology. 8:07 - Tough cuts, but mild steel. 8:35 - A drawing! +/- .001" on 7"? Piece of cake for you. 10:49 - Rolling element bearing seat? +/- half-thou usually suggests that. 11:35 -press-fit idler seat - see title. 12:24 - Forgot to spec it or forgot to cut it? 13:33 - Half thou is fine for a relief radius cut. 15:10 - Gimme a minute. OK, R dims on the idler hub. 15:26 - Here's where we get that extra half-thou. 16:18 - Was wrong at 10:49. What's part #10?

[@ChrisMaj]

Yeah, 1045 cuts really nice. I think whoever did the wheels had different drawings cause there's no radius on the assembly drawing. Easy fix, though.

[@michelrichert9052]

Nice lathe ! I love these big old school machines .. Really powerful, rigid as a rock .. and I'm pretty sure it's precise too .. I would enjoy working on one of these bad boy 👍👍

[@ChrisMaj]

I think it's like 17 years old, so not really old school, but yeah, it's a decent machine.

[@bhekidlamini51]

I need to get myself that Kennametal holder and cutter. 8mm depth of cut with a 0.8 feed is impressive 😊. It also makes nice chips. Good job .

[@seimela]

Where are you working Bheki

[@ICA17887]

Hello Chris. It's weird to see you machining small parts, it's a change, it's good. I love your Kennametal knife tool for roughing parts, it makes great big blue shavings. Thanks to you.

[@ChrisMaj]

I think you guys got a little spoiled with all these big parts. Sometimes change is good 👍

[@dawszelka5461]

Jak zwykle doskonała robota Chris ;) Super to wygląda ;D

[@4418CARLOU]

Great work as usual. When we did shrink fits on 12" dia. shafts, the rotors were put in gas ovens and heated to + .001" per inch. So 12.012" bore.

[@ChrisMaj]

Unfortunately, we still don't have over that big.

[@gwharton68]

Just the part I need for my new watch.

[@BloopTube]

Those Fix8s always surprise me, I thought I was shit hot with my WNMG taking 5mm depth of cut.

[@ChrisMaj]

I'm not really a fan of WNMGs. To delicate for heavy roughing and don't like them for finish cuts.

[@eviethekiwi7178]

i prefer to leave my shirt un-tucked, to allow for easy and rapid exit of chips that want to get to know me a bit too much

Yeah, that might help, but I don't like stuff hanging around.

[@burghardtzerspanung640]

Hi Chris, what is your favorite method to precenter those workpieces? I saw some where done on the Mill in the background, but not the once in the video. Thanks :)

[@ChrisMaj]

All of the centers are done on a horizontal boring mill. I think it's much faster, and I don't have to mess around with the steady rest.

[@theessexhunter1305]

Chris, what is the man in the background singing...as he should stick to turning lol

[@3axisrocks393]

Another great video man. One question, how does this tipe of external TNMG holder indexes the insert in position? Is it rigid under radial and axial cutting forces? Is it accurate when you swap out an insert? We use those that have a clamp that pushes the insert against the pin, very sensitive with any wear or damage. Just want to know your experience with your type of holder. Cheers from Brazil

[@ChrisMaj]

All of my tools use the same insert clamping style, never had a problem.

[@3axisrocks393]

@@ChrisMaj Nice!!! My question is that the TNMG holder doesn´t have a pocket for the insert to register, unlike the CNMG and DNMG holders that you use. Just being curious, not questioning anything.

[@captcarlos]

@ Axis. Not sure you have had a good squizz at that. 14:45 min great shot doing that missed, cough!, radius.. Centre cam and an over arm down into a full depth 1 1/2 side pocket, TNMG insert. Got lots of this style in other insert shapes at home and at work. Work just fine.

[@b2dmastersniper]

Amazing rigidity on that lathe, .350" doc with .032 per rev is madness.

[@58unclesam]

When I was a kid I worked at an outfit producing drill pipe and collars and I had a chip fly right into my ear😩 it burned like the devil and when I reached to get it out it cut my ear too😡

[@ChrisMaj]

The ones that get stuck are the worst. You try to remove them, and they do even more damage 🤣

[@injuredplea]

Do you do any of the programming yourself or is that the job of the 'big heads'?

[@ChrisMaj]

All hand programed on the control. Unless it's something really complicated, then Mastercam to the rescue.

[@adammiller4879]

Iv always wondered about that center you have in the chuck , is it homemade ? I wish I would have thought about that, would make quick indicaating so useful! How close does it get you?

[@ChrisMaj]

That center came with the machine. There's a 10" bore through the spindle and tapered plug, and then I'll put dead center or live center in it. The dead center will get me within 0.002".

[@mattcaesar5781]

Looks good. Is there a reason you dont do a finish op right after the rough so you dont have to handle them twice?

[@ChrisMaj]

They do get a little hot after all the roughing, so I like to let them cool down a little.

[@mattcaesar5781]

@@ChrisMaj ahh gotcha.

[@robertoswalt319]

I heard some banging at the beginning of the video. Was that the QA team performing a little "beat to fit, paint to match" work?

What is mean SFM:400 (122SMM)

[@captcarlos]

SFM:400 The RPM of the specific spindle is set to a constant velocity of 400 ft (foot, 12 inches) per min Or 122 metres per minute which is the metric equivalent, Up to the maximum rpm of the lathe or programmed lesser RPM.

@@captcarlos thank you so much because i am use metric system so i got you know thank you sir

[@semperfidelis8386]

these huge parts you're doing...are they production runs? One-off's? How are you doing them using CNC? We don't see you gauging anything.....you run a CNC program, you gauge the part....make offsets to get the dimensions you need...gauge again.....once you have a good setup w/proper offsets you can just stand back and let it run.......

[@robertocavia5951]

Muy bueno lo de la la base del comparador para acoplar una chapa que direciona la viruta. Hoy he aprendido algo. El video muy chulo. Yo pondria av 0.6 vc 130 m/ min para desbastar, pasada de 6mm al radio. Para acabar av 0,2 ( dependiendo de rugosidad), vc 180m/min pasada 0,3 al radio. Heramienta para desbastar cnmg190616 y acabar tnmg160408. Enhorabuena por el video
