That new kennametal fix8 was my idea and I was bit worried how is it gonna perform, cause boss wasn't really thrilled about it, but I think he's coming around after seeing what it can do. 😅
There is little bit more work on the milling machine. They have to finish the slots, keyways,drilling and few other things. I will try to get the finished product.
Thank you Chris for this great steel machining video, I loved the roughing with those big passes and the nice blue chips and the finish after for a shine finish. I prefer steel for me more noble than gold.
Having seen the newer tip geometry, (fix 8) makes me think why it wasn't done this way....Years earlier. Crazy how something so bloody obvious can remain hidden for so long,..
Этот новый kennametal fix8 был моей идеей, и я немного волновался, как он будет работать, потому что босс не был в восторге от него, но я думаю, что он приедет, увидев, на что он способен.
Congratulations Chris, when the rotation speed and feed rate are precisely adjusted, the wood chips are poured perfectly, the processing ground is smooth
Chris I would like to work with you if we can contact Turkey I live in Istanbul I am 53 years old my profession is lathe milling planer I have 35 years of experience in using radial drills
That cutting edge in the pocket of the Fix8 was WELL used. Have you had any issues with used edges being deformed enough that it doesn't sit in the pocket nicely?
Loved it as usual Chris thank you!! Quick question, the drawing showed that the thread was straight unified thread if I saw correctly, am I right in what I saw??? I’ve only ever worked with UNC or UNF…. If I’m right in what I saw I didn’t know about Straight UN Threads🤔🤔🤔
0:40 - that always make me wonder... People start machining stuff with no coolant, and somewhere "in the middle" of heavy cutting they decide "hey, why not use it? after all, it is paid by the company, so let it flow..." ;-) Seriously though, that dry run makes the insert quite hot (presumably), and apparently (AFAIK/ as I was told) it is a very bad idea to flood heated up carbide inserts (brazed-on "tips" or them "mechanically affixed" newfangled gizmos) with cool coolant. "it's either you run it dry all the time or flood it from the very beginning" I was told "quite some time ago" (like, forty yrs ago). Something changed since then, I suppose...?
Most of the time it's just for the video so I don't get my camera wet, but you are right some inserts don't like when you start without coolant and then you decide to use it, but by now I kind of know which one. Jeśli mogę zapytać, jesteś w Polsce czy gdzieś za granicą.

Good work as always! The surface finish looks odd, was the tool not cutting it? (ha) Those were some nice blue filings, was that the FIX8 Turning by Kennametal? I recently saw a video (Titans Of Machining) where they did their best to push the tool to its limits. If i remember correctly, they cut 0.400" DOC at a crazy feed rate, like 5 inches in 0.9 seconds or something with steel.
I mean it's a different story if you have a 20lbs piece, 5" diameter and 4400lbs piece 15" diameter. Also we have to pay for the tools/inserts not like Titans where kennametal just throws tools at them just to try it out .
@@ChrisMaj I've never use it but after saw your films, among others, I'm starting to wonder :) I use SECO and SANDVIK tools generally... Low prices, accessibility... live in east Europe, war time and so on... ;/

That insert sure does a good job peeling the bark on that shaft.

Wow! What a beast of a shaft. Those inserts do a great job on interrupted cutting. Thanks for another excellent video, Chris.
Yeah, it's a fairly good size.
When Chris machines the chips fall and hit with a CLUNK! .35 depth of cut... Wow. Good stuff sir, thanks for sharing.
Well thanks for taking the time to watch it.
A good idea to machine the slots before finishing the shaft to size, because of possible movement.
Another quality video, thanks.

your roughing feeds and DOCs never fail to impress me xD
When you have the HP, might as well use it.
First class machining with some serious keyways.....thanks for showing, Chris.
There's more work to be done on that shaft, but that's horizontal boring mill.
Blue Chip Special! Love it!

Nice work! That's one BIG shaft.
That's the kind of jobs that I like "BIG"
Nice work, those FIX8 inserts have a great MRR!
Yeah, I'm starting to like that thing.
10:05 Nice angle. Beautiful finish on this, Chris.
great job looks congratulations
Nice Work, Nice Shaft Turning...
Thanks for watching glad you enjoyed it.
Beast of a shaft mate 👌 got to get one of them kenametal tools to try out . Great video thanks for sharing 👍
I'm starting to like that tool.
if i remember my tempering colours blue chips means they come off at about 450C about 842F
I know they are hot when they smack me in the face. 😅
@@ChrisMaj you gotta have small burns all over your arms, and chips in your pocket when work is over ;)
Still watching..
Great jop
good video Chris Maj

to cut a thread ///s-- on a split shaft >.,,very hard to do , and maintain thread mean tolerance .well done sir..
It's hard on the insert that's for sure.
Just good to see some decent machining being done. Thanks.
Glad you liked it 👍
Interesting project. Nice threads.
There's much more to it this job, hopefully I'll be able to get it on video.
Thanks for sharing 👍

Have you had any issues with used edges being deformed enough that it doesn't sit in the pocket nicely?
I haven't had any issues with the tool yet, but I only had it for few months now. I still use my good old CNMG644 for smaller jobs.
Either the boss bought a lot of them cheap or those new roughing inserts are working out to be good.
I think I'm getting my money's worth. I still use my trusted CNMG644.

@@_miobrot_603 It's good that we understand each other.😅
Hi Chris, what sfm you running in that 1st cut roughing?
Around 350 sfm, but sometimes I'll adjust the rpm as I go if I don't like the sound that tool is making.
👍👍👍
Geil! 👏👍👏👍👏👍😎
Are these all for a steel mill?
What’s the measurements of this lathe?
Swing over bed 37.5"(950 mm)

Is it cnc lathe ?
Yes it is. Hankook PROTEC-9NC
Which insert and holder it is ?
0:17 Kennametal fix8 insert KCP25B
out of curiosity, how much does such a piece cost?
That I don't know, I just work here.
Why do you chose do the finishing lathe after to do the keyways??
There was a lot of material to be removed.
Hey what's with the duct tape on the tailstock?

how did you rotate the shaft while cutting 3 slots
I'm not sure what you mean.
@@ChrisMaj how did you fine-tune the positions of the slots?
@@anonymousabdi7428 5:55 they drilled 3 dowel pins on the face of the shaft .
Your sequence of operations doesn’t make sense to me.
I'm sure you mean the milling and then finish turning.
Ok, let's hear it?
Yes.
@@pvtimberfaller SO you would finish the turning and then cut these 3 slots? Very smart 👌
