Rolling Mill Shaft | KENNAMETAL FIX8 | Hankook CNC LATHE

[@ksanalyticalsystems2438]

More material removed in one day than I've done in 10 years... Always great to see how you approach these jobs.

[@buynsell365]

This was a VERY interesting peace !!!

[@forrestaddy9644]

I'm impressed. He miked the threads without dropping the bottom wire in the chips - on camera! What I REALLY want to see is drilling all those super-deep holes to intersection. Lots of surgical risk on these large jobs. The man on the tools really earns his premium pay.

[@ChrisMaj]

Over the years, I've only lost two wires. We don't have the equipment in the shop to drill holes that deep. I would like to see how it's done. I've only seen it on youtube.

[@forrestaddy9644]

@@ChrisMaj Definitely a gun drill job. The customer won't be happy with the tooling charge. What? 7 feet deep with a 5/8 drill? Yowza!

[@cyclingbutterbean]

Blue chip special right there. Way to rip the chip! Those FIX8 inserts are vicious. Of course you have to have the power and torque to maximize their efficiency, and that Hankook sure looks like it has both to do just that! BIG fun!

[@craigsbully]

What? The hotter the chip the better. I've only broken inserts on cuts that where below the chip-load recommendations.@@yeahright5227

[@johnlawler1626]

Great piece of turning and milling mate 👌 thanks for sharing 👍

[@craigsbully]

Color me impressed! Measuring the large threads with Pee-Dee Wires?! that was awesome! great job on removing more material than my lathe weighs.. LOL!

[@ulanarni8804]

Gute, reelle Arbeit. Keine Show, kein Gequatsche. Man merkt, dass Du kein CNC- Titan bist. Super.

[@markanthonysmith413]

Another Great job Chris, a lot of work with all of the setups as well.😀

[@paulmace7910]

Thanks Chris. Yet another example of how to combine the best of CNC and good old fashioned machining knowledge to produce giant one-off parts with finishes and tolerances that would be hard to match on parts of any size. Good work as always.

[@sicstar]

Chonker part, Chonker lathe, Chonker chips. Gotta love those FIX8's they really murder some material. Also that chip deflector looks pretty much like what me and a coworker build ourselves, very versatile and reliable design ! :D

love the chip deflector.....very good idea....

I could use a few more .

Awesome the scale of your work is amazing ty Chris

The live center in the spindle seems like a good visual gag for april fool's but here it neatly solves a problem.

[@jimurrata6785]

Woo hoo! Here we Gooooooo!

[@TexDrinkwater]

I would need 3 hands to deal with those thread wires and huge micrometer.

Years and years of practice

Impressive work Chris.

Very nice work wow

[@juliusmilo5959]

Nice job...Thank You...

[@ICA17887]

Hello Chris, thank you for this great video of machining large parts. I saw you used small rods to check the threads with your big Palmer, but this one doesn't seem to be magnetized? It would make your job easier if they were, wouldn't it? Have a nice weekend and see you next Chris.

[@구지면흑탄두]

I always pay tribute to the wonderful work! How much is your large CNC lathe ? smart and strong monster !

[@АлександрМомот-г4й]

Great job! My admiration knows no bounds! I have high wish to do something similar, but my turner machine smaller and hasn't CNC.

[@the_rad_Panda]

Nice work! How on earth did you drill that super deep small Diameter hole in the center? Gun drill? Keep up the content! - love your professional work! Love from Germany

[@ChrisMaj]

Yeah, gun drilling. I've never seen it how they do it, though.

[@MachinedComponents]

Hi Chris, thanks for all your content, I have learnt alot from watching you. I was wondering how many minutes cutting you get out of 1 rouging insert edge.

[@ChrisMaj]

O man, that depends on a lot of things. Your material, doc, feed,your setup, and even your machine.

[@PundhyLuzino]

Selalu 💕😍

[@ypaulbrown]

WOW !!!!!!!

[@stewartfrye]

Is it your judgement as to how much to leave on extra for run-out correction after hardening, or are you advised by?

[@airbus7808]

I would also like to know!

[@ChrisMaj]

I did this part a few times already, and it usually came back from flame hardening within 0.010"~0.015" run-out. I don't know what happened this time. For short parts, I'll leave less cause they don't move around as much. It also depends on how deep they the hardening has to be after machining.

[@raybrown5890]

good job

[@warrenjones744]

How hard is that material from the mill Chris? and is it nice and consistent all the way through to the middle? Also it looks like the Fix8 is working well for you. Cheers

[@ChrisMaj]

When I started, it was around 340 Brinell/ 36 HRC. They did all the inspections afterward, but I didn't get any details. I like it more for smaller diameters.

[@ИгорьСухов]

Просто красиво!

[@nickj2508]

isn't using the Horizontal boring mill cheating to make a cone?

[@ypaulbrown]

nah,,,,,,,better than a battery operated drill motor.....

[@ChrisMaj]

Yeah, kinda, but my steady rest only goes up to 9", and they don't want to get me bigger one.

[@TheNoobShadow1]

What kinda the normal operating temp for a spindle? at 3:42 ?

[@ChrisMaj]

Anything under 100° C.

[@chrisjennings4569]

Ok, I gotta ask. How the molly hell did you maintain straightness in a relaxed state without using a lathe dog?

[@brandontscheschlog]

Very cool! How do you create the radius on the turned part? Do you have a special fixture on the compound that allows you to do this?

[@ChrisMaj]

It's a cnc lathe.

[@semperfidelis8386]

Why did you need a center in the headstock?

[@maciejhof]

Where are the long holes through whole shaft ?

@@ChrisMaj Where is the drilling of it ? :-)

[@ChrisMaj]

​@Mac Hof, we don't have the equipment to do that.

[@romanchomenko2912]

Stainless steel is a bugger to machine so the CNC had to use diamond tipped lathe tools. There's always wastage in turning large in between centres but any turnings are placed into 200kg oil drums for scrap.

[@kevind1865]

Its 4340 QT and no diamond tipped tools.
