1:04 Titan says: " Let's go break a tool " ==> 1:47 Kennametal goes like: " Let's go break a spindle "
Nah it was only trochidal milling😉😉
LoL
This was my 1st time to see heavy cut without tool break, 👏🏻 Awesome
That not normal EndMills....😂
45° and going+ fast
@@tibseflups6674 it was not, that was just the look and sound of crying spindle bearings :S
Or at least the tool decided to do trochoidal on a straight path 😂
That milling head is gonna break before the tool 😂
Yes, it appeared the holder was almost gyrating in the machine a smidge and did show some tool marks to back it up some. The kennemetal tool line is obviously some of the best their is by demos like this and others with the Harvi 3 so just imagine even with a smaller machine with lower HP how long the end mills will last.
crazy how the stiffness of such a machine is the limiting factor and not the mill
lol i can break my 1000dollar router by pushing the spindle with my bare hands
Its not the machine. Its the wrong holder in the spindle.. not a dual contact.
@@xtiz You mean that the Holder is rotating in the Cone of the Spindle. That would be bad news, because then the Cone is trashed when literally metal is rubbing on metal. It will work but will have a huge runout. Had that case with my hobby CNC, which is really powerful and sturdy for what it is. But also doing a heavy cut in aluminium 1,5- 2xD deep, but i didn't obiously pay enough attention to my workholding. So the workpiece shifted just a little bit and the 10mm Endmill jammed for just a second. But the spindle was rotating at it's programmed speed while the toolholder slowed down for one second (because of the jammed Endmill). The Tool didn't break surprisingly, but the Spindle cone had deep groves in it after that. Getting that replaced and everything up and running again was a major headache.
Thank you for adding metric values. You are going global! Keep up the good work!
jeez, you're gonna break the machine before the tool !
1:50 Tool to Titan: I'm gonna do trochoidal. OK?
Titan: BOOM!
The chuck was too weak not stable enough
Dang that was impressive.
Love your channel
Fair play for proving what can be done, doubt the spindle bearings and drawbar enjoyed the experience, but as a one off it was pretty incredible!
There’s a few people in my shop that will break that endmill........ by starting to mill with the spindle off.....
or m4 instead of m3
Titan, I got to hear you speak 5 years ago and you had me convinced that I could climb Everest with Tennis shoes, Glad you are doing well.
A well deserved plug for Kennametal Tools, and quite right too. They don’t only talk the talk, they walk the walk. You’ve got the zombie mill, I wonder what this should be called. Perhaps “the spindle reaper”, or “the Rambo”, (“don’t push me to far”).
the tool holder was like yep i am gonna dance to that sexy tool
machine: let s do it together
Machine: you cant survive
Tool: hold my beer...
1:49 i can See the Spindle wigle 🤠😆😆. Poor DMG machine 😧🇩🇪
wow impressive , even if i had pain for the spindle that seems to flex during the second slotting at a moment ! crazy tool well done kenna!
RHINHORNS its the Toolholder not the Spindel
@@Kevin-tf4fl yeah better for the machine integrity :D
@@Kevin-tf4fl what in the tool holder is allowing that movement? When I first watched the video I thought the table was moving but after seeing your comment I agree that it looks like the movement is in the tool holder.
Jeez, I've never seen a machine flex like that before, that can't be good for it.
Craig Krueger this isn’t the Maschine is it the Toolholder
@@Kevin-tf4fl Even at 1:50? You can see the spindle itself there, and it does *appear* to move quite a lot, but I dunno :)
@@Kevin-tf4fl the tool holder is flexing a lot more but the machine is definitely flexing too
@@85CEKR i think that is not spindle or tool flex - but servo's hunting and struggling
@@nonjb3811 yeah that's what I thought at first too. Go back and look at it again, I think that tool holder and spindle are flexing
Never known a holder to walk around in a spindle like that
It’s just because of the full slot and amount of pressure I put on it.
@@TITANSofCNC Oh man I thought you were doing an adaptive slot at first. Man that tool is amazing to hold up beyond what your machine is happy with! Well done.
@@JDFuchs Yikes. (I also thought that.)
@@TITANSofCNC so the tool holder was being sucked out of the spindle and allowed it walk around? We were thinking it was the axis's moving due to the force.
@@euclidmachineanddesignllc704 wrong holder, not a dual contact holder in a dual contact spindle..
I can’t believe I just watched a 3.5 minute video of a single end mill...but your enthusiasm made it oh so entertaining to watch!!
The stress that the machine feels in the second slot was insane.
During the 2nd pass, the milling cutter performs trochoidal movement or the spindle has been damaged?
This goes to prove what ive been saying for a while. Tooling is surpassing our machines. Our machines and work/tool holding will give before the tool with top of the line tools.
you should try our "Diver" cutter from Gühring !!
I'm backing this ;)
I tried a couple guhring divers the other day doing some slotting of steel plates, they chatter and it eventually exploded doing a straight plunge as advertised. These were the small diameter ones 3/16" of an inch, I also tried a Niagara that was chatter city and a Kennametal Harvi 1 HPHV that ended up being dead silent and lasting. I'm still using the kennametal tools on the current job. Good tools empower you to make more money faster. Maybe the diver is better in the larger sizes or with better machines, I don't know.
@@multiHappyHacker I did my final exam with the Diver and it did better than the kennametal in this video.
With a 11,5mm endmill I milled 1xD slots with 290m/min (ca. 8000rpm) and fz=0,75mm/t (ca 2400mm/min) into 16MnCr5 (5115 in America). Nothing broke and in the evening the mill looked like it was new.
@@flozo98 The TE is fairly recent, in what way did it do better?
I'm usually not impressed by videos of testing cutting tools, but I am very impressed by this one. I might have to see about getting some of these for our shop.
That is an incredible tool! I would like to see further tests. What HP is your cnc working with? Looks like a small machine. I though your spindle was going to buckle, (suprised the tool didn't break) when I saw the wobble!
OMG, I think I saw the spindle flexing at 1:49. That tool is amazing.
That's the toolholder. DMG Moris spindles ain't flexing LOL
@@pakman422 If you look again you see the whole spindle flexing.
This is unbelivable . incredible metal cutting.
It would be interesting to know the temperature that tool reached doing this.
At the edge its accually a few 1000C.
Ideally, the heat produced in the cut is passed through the chips as they are cut away, hence the dark blue color. I bet that tool was still a little too hot to touch though!
Hello Titan , this was impressive cut also it was really interesting to see that flex from toolholder ! Please comment on this wobble of the tool on your next video !
Cried for that poor DMU50, hard slot machining at HSK63 5axis machine... Make that cut at any OKUMA and BOOM, zero wobble . Also try that on HAAS please, guaranteed Estop at slot lol . Respect to Kenna btw
I think you are hitting the limit of the hsk 63 connection, might do better if you can get a shorter gaugelength holder.
But really cuts like that are for hsk 100 or 50 taper machines with box guideways.
Just ordered a couple of these for my shop. Definitely not gonna put them through as much as you have but I'm still looking forward to seeing how well they perform for me
That was very impressive.
Here’s a man who loves his work.
Hmm, and how z guides and spindle bearings feeling like after that torture?
Bearings: I dont feel so good
@@ipadize did you do it? *yes...* What did it cost? *Everything*
They didn’t notice a thing. It’s a DMG MORI, not a 97 Haas.
They feel good
well, that's steel 1018 I'd like to know what that tool can do with a harder steel o even stainless steel, of course the tool wil break but I'll like to see some machining on that
Loving that enthusiasm!!
This IS KENNAMETALLL !!!!!
Sparta style
You were driving that so hard you were getting visible flex in the column. That's just nuts.
Was it pulling the tool holder out of the drawbar?
Would love to see go thru some D2 like that.
good lord !! just look at the stick out but it did chatter in Y axis mid point, still terribly impressive and NO coolant. amazing !!
1:39 its a masacre. Please try this on umc 750 Please Please Please :)
I would love a car the colour of the blue chips.
That was insane! You blued in the plunge, but, you didn't blue at all for the rest of the cut. What an end mill, WoW!
They were blue before they hit the floor though!
@@Blown460 They were blue as it came off the tips of the end mill. During the plunge. Notice the rest was slightly tinged through the rest of the cut. Imagine what it would cut like with flood irrigation.
WOW. Could we see this test again in 4340 or H13 in the neighborhood of 45 HRC? That would certainly convert the skeptics!
Maybe time to check your spindle nose runout and tram after that demo...looks like it almost destroyed the holder....severe wobbles going on!
Oh dear, it looks like I might have to buy a new endmill!! Nice one Titan
Reminds me a test with Iscar ECR 15 years ago. 16mm 2xd full radial 15 degree ramp. No problem at all but getting the hook like chips away... I've never felt such uncomfortable on a machine as in this situation.
Im impressed
Very professional video. Excellent demo.
Which will break first this bit or his XS shirt
🤣🤣🤣🤪🤪🤪
XXL Brother...
How much NM(newton force) / Kw of a spindle power as minimum required for steel milling process ?
Yes cool to see from your heavy machinery To high speed🥳 👍🏻
Awsome footage and tool.
Never thought that a holder could flex like this.
But thats why you don't use crappy little DMG machines and bad toolholding for hardcore roughing.
Cheers titan keep it going.
Jenzzzii crappy little DMG? That’s a Cat50 spindle...
@@daerrickjohnson1349 No it's not.
It has HSK63.
That is insane...
U think that hydraulic holder would would do better than a heat shrink holder? I've had .75 tools pull out of shrink fits.
I really like the new mori controls.
i Wonder what was the spindle load, still insane milling
Is the cooling off intentionally or just for filming purposes? Lots of heat going out in those chips judging by the colorization. Would coolant introduce sudden thermal stresses?
Wow those chips are insane!
I feel bad for your maintenance guy tho that's a lot of abuse on those machines...
My machines are beautiful... everyone knows that.
@@TITANSofCNC You are beating the crap out of your machine. That is not beautiful. Everyone knows that. You need to own up to your unsportsmanlike conduct. BOOM !
@@FluxApexEng I am not the least bit afraid and I agree we must learn our machines capabilities. However, like most of the respondents here, I view this as horrendously damaging to the machine.
The machine in this video has suffered permanent serious damage to the spindle connection. It will need regrinding of the splindle to once again meet factory performance specifications.
This kind of disrespect to a machine is not at all heroic, as you might want to see it, but simply sensationalistic. "Let's break something" > BOOM !
I thought the tool was replaceable not the machine, awesome
OMG. That is amazing. What was the Spindle HP during this cut?
Cheers
Willy
💥 boom! Insane. That spindle flex
Wow. Just wow.
Hey Titan!!!! What tool holder are you using???? I'm going to try exactly what you did but with 40 taper dual contact and see how well that slot handles as well. I will also be using a DMG Mori.
What I see: An Endmill
What Titan seems to see: A Weapon of metal massdestruction...
Thanks for sharing!
Mario,
I absolutely love this stuff… Like a Big Kid.
Murdering Metal and taking cuts that others think are impossible…
Have a great day!
Titan
@@TITANSofCNC Exactly my thoughts when I saw one of you videos the first time... :D "Nah, that dude is nuts..."
A couple of videos later "Uhm... maybe my former supervisors are nuts or just a bit inexperienced..." (I am a operator of a 5-axis milling machine, formal "industrial mechanic specified in milling")
keep that energy!
"we are gonna go 45 degrees straight down" :) ...but awesome video
Exactly... straight down in a linear direction of 45 degrees... going from high to lower...
I just realized some deflection was induced to the spindle, probably a shorter lenght tool holder would have eliminated it
This makes it quite apparent that the x axis is built a bit more rigid than the y axis. Either way I hope to never visibly notice flex on any machine I’m working on 😳
They always flex at some point... that’s what taper is when cutting. This is just extreme and not a real world application... because I drove straight in pushing forward so the pressure on the EndMill pushed it in multiple ways. Good education really to help people understand the difference between a HSK63 and HSK100 and what’s best for what application.
TITANS of CNC: Academy I didn’t expect a comment from you! I am doing the academy right now and I’ve been loving it!
This is awesome and I appreciate the tests you do because I wouldn’t get to see anything like this otherwise! So crazy to me that tools are getting so advanced that they are no longer the limiting factor. Great work!
Glad your taking advantage of the Academy! It’s just going to get bigger and more advanced.
Titan
Wow, very impressive!
jaw dropped! i wouldnt take that cut in ali, fair play to you guys!
Yo I’ll have some of them shavings please, they look sick..
Time for some cat50! At first I thought you where doing a little arch milling until I realized it was flexing xD
oh Titan when you talking about our trade . Its just more awesome . Boom right on the money ! crazy video crazy tool crazy man ;) . And that chip comming out . a lot of volume on that Tool . cool keep it up from EU !
Hey I'm just curious but does Milling like that throw your machine out of spec?
Lets roll them dice and "Send It."
this is so good I got it on Loop...this is priceless..
I legit cringed at that 2nd pass. Good lord. It's hard to imagine the stresses going on inside that machine from that. What arbor are you using? Some kind of HSK? Doesn't look like 50 taper.
HSK63
It beats the hell out of my Bridgeport 🤭
Does anyone know what this "Harvi 1 TE" is made out of?
And does anyone know what type of metal that is very hard, almost indestructible that could be used on punch tips?
Thanks.
are there endmills from kennametal in metric sizes?
Amazing!!! was thinking the tool would break. In shock at that!
Seriously impressive.
Machine, ohh my acting ball bearings. What's that noise? Flat roller bearings? Amazeballs though
Remarkable tool
What is the spindle load at durning this? 180% ??
how much cost for this tool ?
Thanks for this video!👍
It’s crazy to see some1 actually push it to the limit! Ur videos amazes me that’s a fellow shop owner. Thx for ur videos!!
Oh my god ! I never test kennametal tool juste drills. But if i make this with jongen or fraisa tool they break instantly during the entry ! Can i have the tool ref?
i want to see on the haas, boom goes the cnc
hoooly crap. I just bought a bunch of kennametal harvi 1s for slotting some steel plates too, absolutely silent, amazing.
yeah you're gonna need a stubby heat shrink or stubby weldon solid holder
Annihilated that steel! I want to see more! 💥Sparks and rooter tails of blue chips💥
That's one badass tool
Titan : lets kill this tool daaamnn!!
dmg mori: hold my beer
kennametal : uh, sup boys?
Booms all around
Hip hip, BOOM
Great example, that holder length also matters. The tool is insane tho.
How do you know, if it is the most advanced tool? Anything to compare it to? Because I know some European brands that are ready to compete 😁
That spindle floats like boat! 🤣
Holy Hell.....that was insane....spindle nearly breakin....
