Thank boys!
Emailing you from Stony Creek, Ontario Canada. You guys are awesome. Really appreciate what your doing. Just starting CNC machining after 25 years or so. I'm a manual machine guy but my heart was always with the technology aspect of machining. I was really apprehensive on starting back on CNC but you guys made it easier and less intimidating. I'm still nervous but excited and will keep watching your vids and gain some supper knowledge. Thanks again for what you guys are doing for the boys here at home! God bless! 👍👍
Shout out to Danny Davis and all the Kennametal folks!! Great product and Great pride in what they do.
Come on guys you're doing great work in there but after all efforts u don't show us the tool doing the actual cutting? It comes down to be a theory if u don't show the actual work so i wish u do, tx.
Yep, can't bear to listen to this crap beyond 1:47 - skimmed through the video but it does not show any machining. Downvoted.
Samir Samir We purchased this tool, didn’t work at all it made 3 pcs, we had to go back and use our Melin 9 flutes end mill which did like 10 pcs, do not waste the money on this tool 👎🏽
Amit Panchal what material did you use this endmill in?
@@Sffker ... Waaaaaaa.. Excuses
@@sanpanchal you used this tool wrong.
Used to cut some Inconel plates, about 3.500" x 3.500". Basically an endmill per plate. Brutal material.
This dude is all gas no brakes
You are the teacher of CNC. The right man for the job. Stay exactly as you are.
Dam that's just so true, don't know how many endmills ive snapped running in inconell 728 😅 k8nda happy I switched job out of the oil industry and into medical jobs instead
Best regards from Poland. I want to thank You for inspiration. 12 years ago I’d dream to be a cnc machinist, naw I’m constructor and cnc programmer. I’m best with laser and bender but milling was may dream, thank You for tips. Today my R&D team made first mill part. Best regards again, Renex R&D team Poland Wloclawek
Cześć! Jak zostać operatorem CNC w Polsce?
@@Igor-ip7bc uczyć się, zrobić jakieś najprostrze szkolenia CNC a następnie szukać pracy. Na start nie będzie za dużo bo w tej dziedzinie umiejętności w prost przeliczają się na hajs zarabiany. Ale zasadniczo to podstawa rysunku technicznego i chęci i nie powinno być problemów.
Osobiście na start polecam raczej mniejsze narzędziownie, gdzie jest mniejsze tempo pracy i łatwiej o porady i inne
Bardzo Ci dziękuję dobry człowieku!
I have some experience cutting inconel, and that stuff is CRAZY hard, it is very impressive for a mill to last for 6-7h Cudo's to Kenametal for creating such a beast!
I'd like to see your thoughts on insert tools vs solid carbide in a vlog!
Each and every week I'm inspired by this man and what he's accomplishing around the world. Truly an honour to be following and getting great advise from this legend... BOOM brother 🙌
Thank you CJ
Thanks for showing it at work.
I was waiting to see the end mill cut. Do you have a video of cutting 718? I used to work with it it was a nightmare.
I only listen a lot of words...
These are areo space parts you don't want people getting a profile of the parts without a lot of security clearance
Yoo bro. Have a look on thw Fraisa-tool. ZX Generation is tough ! Also the SX can be used but its not its main material its for stainless steel.
@@Deluxxxe216 SS and titanium are different beasts from what I've seen
Thank you very much Titans!
Titan and crew, another great video. For the content, but more as it shows yet another aspect of machining which is lost to most. Not that the tool keeps breaking, but why the tool keeps breaking. I am going to have to go into the engineering side here, but the more you grasp as a expert in machining the better your are. Carbide, like every other metal bends, flexes, twists while it is doing it's thing. The law that governs this is called Wohler's Law, if you can grasp the math and the physics, identify all the variables that you deal with while machining a part and then apply the law to the application you can troubleshoot an issue such as this. There was a deflection (stress) in the tool over a period of time, that after a set time that stress became greater than the tool's capability and it failed. I wish I could get my hands on a few of the broken endmills to see just where the breaks happened and find what caused them to break. Sometimes being a good detective is much cheaper than "let it cut and see what happens", than again sometimes that is the only thing you can do. There is a recipe for everything, pancakes, apple pie, and endmill selection. The better you measure the ingredients, the better the outcome. Would you have seen improved tool life from a smaller gullet/larger core tool, a shorter flute height tool, a change in helix angle, possibly switching to an endmill with down-cutting flutes putting the tool in compression as opposed to tension, or just using the tool you have and conventional cutting as opposed to climb cutting reducing the deflection by the tool cutting into the material instead of cutting material off. There are soo many variables that you have to take into account, but the better you are, the better the product. This way of thinking is how we are going to bring more manufacturing back here, getting past the old ways of just going with it, and bringing the art and science together.
Hello.
Where can I find more info about this Wholer's law?
Best Regards.
@@miguellimon2609
Friedrich Wöhler
was a German chemist who ushered in a new age of organic chemistry when he demonstrated that urea, a chemical produced in the bodies of animals and humans, could be manufactured in the laboratory. This discovery overthrew the then-current theory of vitalism, which held that the chemistry of living things was governed by a different set of laws from those governing inorganic chemistry
Wöhler's Law states: a law of strength of materials: the breaking strength of a material decreases with repetition of the strain and with the range of the strain variations.
Plethora of information for more than just chemistry....
the main problem is the tool becomes blunt,tool wear. the the loads on the tool rise till the load reaches a point were it fatigues then brakes, also as the tool bend due to the cutting loads the cutting angles change which is not going to be for the better wear increases load rise. interesting you measure time. Time is not important its the total metal removed that maters .
As an engineer I think it's important to note that carbide isn't a metal, it's a ceramic in a Cobalt metal matrix.
They are machinists. Not material scientists, or end mill manufacturers. I like your zeal, but its wasted here. They cant waste time on such things, they are either making chips or losing money.
Great video guys!! Been in the industry for over 50 year,,,,yea,,,,old fart here. But I am still learning some things from you guys! Thanks! And thanks for the great deal on your Dodecka face mills!!
I was just an operator at my last company but that End Mill is Brilliant !
No need for sound when you can see Titan talking. "100 Thousand Dollars" lol
keep up the good work mate!
I watch these and have no idea at all what anyone is talking about. Just like watching them geek over this it and see the material being machined. Never seen someone get so excited and enthused about this stuff - Brilliant!
This is the machinist version of "It cuts. It slices It dices. It chops, NEVER NEEDS SHARPENING !
Three easy payments. NOT SOLD IN STORES
Your intro is excellent, thank those that made it.
Can you do a video on shop organization? Storing endmills, drills, vises, toolholder etc. I’m in a small shop where everything is pretty much thrown together in a cabinet with buckets and bins and I want to try to organize it but I’m not sure how to go about it. Awesome videos by the way, keep it up!
Get a library index card cabinet for mills and drills. Lathe chucks/vices/fixtures I shelve in labled clear plastic tubs.
Chauvin Emmons
I like what I see, unfortunately I don’t think I’d be able to convince the boss to buy some of those. Before I started working here a little over a year ago, they were buying cheap, Chinese HSS endmills. I convinced them to make the switch to carbide endmills from a reputable company and even that was tough.
for our own future, we should keep having competitions of the best hard material cutters
MY NAME IS KEN HENDRICKS. I AM A TOOL AND DIE MAKER. I WORKED AT WESTING HOUSE FOR 18 YEARS MAKING ALL THE HARD PARTS. I HAVE WORKED WITH A LOT OF INCONEL 718 AND MONEL 500. A VARIABLE PITCH MILL 1,0 DIA IS THE ROUGHING MILL AND THEN FINISH WITH THE BIGGEST MILL THAT THE PART ALLOWS. I HAVE WORKED EXTENSIVELY WITH KENNAMETAL
Titan some of us can't get the newest and best machines. You've talked about your start on a TRAK mill. Can you make some videos on how to push a TRAK mill for best efficiency and machine/tool life?
Awesome info Titan ! Your the man!
I remember Ben Rich's book about the Lockheed Skunkworks mentioning that machining titanium was one of the hardest problems they had developing the SR-71. They pretty much had to make all their own tooling.
Great book! Highly recommend to anyone who hasn't read it!
Once you know when the tool is about to die, stop and pull the tool a bit early. # 1 A dull tool is work hardening the surface and the next tool’s life will be shortened. #2 When a tool breaks, it can leave imbedded carbide in the part just waiting to hurt the new tool at the very fist moment. #3 A broken or badly chipped endmill has no regrind value. Goering divers are are like zombies in 4140 HT 38Rc. Factory regrind/recoat are better than new for some reason, go figure?
When Titan talks about his namesake.. Titanium.. : )
We use ceramic inserts (SiAlOn) for Inconel 718 on work (for roughing/dry). The cutting speed is 25x higher than carbide - great time saver.
With carbide endmills try to mill Inconel in conventional milling direction. It helps with hard materials, when your chip thickness starts at zero!!!
Ceramics are great with the right application, but you also go through a lot of inserts and down time changing tools unless you put time into your machine management.
With these High End EndMill ... Always Climb... the doors is up for Inconel and definitely don’t want to run over any chips etc.
Suzaru87 I agree ceramic would been the better choice here. You can not only load Redundance tools on the machine and have it set up to change after so many mins and have the tool management for tool load setup would be better. Plus if he had a DMG Mori machine you can unload the tools as the machine running and change insert while it’s still going.
@@vincelombardi2669 doesnt necessecarily have to be a DMG mori to do that, i have a Mazak Integrex I-100ST and can do it to 🙂
Johan Hägerström some machines you can’t load tools from the outside. I am not saying DMG Mori is the only machine. But HAAS and Doosan I know for you can’t.
I cut inconel with hss and grease mixed with old motor oil. Shaper and lathe, just a bench grinder and 5/8 inch square tool blanks.
Thank you for your wisdom!!
Try green leaf ceramics I use them every day on inconel 718 went from roughing with carbide at 90sfm to between 750sfm to 900sfm depending on which tool
Turning of course
"leave a comment were good about answering comments" - answers no comments hahaha
My full respect from germany. BOOOOM!
In Germany you guys are not using shitty machine tools like Haas.... They're not a rigid cutting machine in materials other than aluminum........ Many shops in the US try to get away from spending some money on a well built machine which in my experience all are built in JAPAN....... sorry Haas....
All my endmill look like ballmills after a production run. I pull out endmill from scrap buckets that are perfect for roughing at high speed. Power milling they will snap within a minute
Hey brother GOD bless you and keep up the good work
Can you do a video explaining dynamic work offsets on the UMC750? Been programming using the pivot point on older 5 axis trunnions and I know the UMC750 and newer trunnions are different.
I love your channel Titan! Keep up the good work!
great video again guys, keep it up
A lot has to do with the quality of machine and tool holder. Try a test back to back with HAAS vs Mori / Matsuurawith the best holder.
I GUESS ITS NOT CUTTING ON A HAAS cnc Center. since its not showed. some mori seiki, okuma, nakamura, matsura, japanese stuff. good video
I would like to see the feeds and speeds that you used for this endmill. Also the formula. Cheers
titans grunts are world class
He reminds me of Macho man randy savage when he talls lol
The 🧟♀️ mill. It munched and munched metal.😂
Ok a side note Caron engineering makes some amazing load monitoring tools. At my work one of the machines is equipped with their product and it catches and stops the machine the moment of insert damage before cartridge or work damage.
No need to have someone watching a mill run because a tool might fail.
So ive just used a heli 3 on inconel 718 it lasted 40 mins!!!! 1/2 dia 1.100"doc, 0.025 step, 1220 rpm
VERY GENIUS BRO
Imagine that. A necked cutter with a stiffer shank lasts longer.. who would have thought...
Its Kennametal advertising... what do u expect?
marketing or not this tool saves money.
Titan is an inspiration
Was this material Age-Hardened? What do they call the extra stuff that was done to it?
Interesting that when working with this material that you fully expect to use up tools. In other words you are looking at how many tools you'll use up per piece, instead of how many pieces you get per tool. Ouch! Expensive.
Try out cutting molybdenum. It's sintered and crazy hard, you also can't conventional cut or it will crack. Climb cutting only!
I’ve been CNC machining for years and I’ve never found an instance that needed a conventional cut. Climb cutting is the only way to go
As a machinist for BOEING! Who uses this exact type of end mill at least weekly i can tell you this cutter is a BEAST!!!!! in my opinion it os the best end mill for titanium!
liver poolFC hey man. What machine do you use for milling titanium with this tool?
I love those endmills, they were exceptionally good when they were made by Hanita - before Kenna bought them.
After watching the film, we also bought 2(Harvi III D16MM AP32MM Z6 R3 N) cutting Inconel718+
Vc=32 M/min ,tool life only 37mins
Vc=60 M/min ,tool life only 70 secs
We can still look forward to increased tool life
How can we achieve 7 hours of tool life?
from taiwan AMI
Try YG1 endmills made for hard milling. They are made in Korea though, but OMG, I use to use them for hard milling mold cavities in powdered metal. No endmill would last longer than 15 min. Salesman came in, gave me a YG1 to test. Thought he was all talk. Let machine cut all night long. Was expecting a broken cutter. Came into work that morning and was shocked that it wasn't only still cutting, endmill looked brand new and finish was like glass. Not only that, it was under $100.
I just use HSS with Cobalt to cut my Inconel 718. Only use about 650ish tools and never finish the job. Good stuff.
Dear Titan, I have huge respect for you, and your mission of education! I think you have a lot to give to this world. Just a gentle reminder that this fawning infomercial would have had more educational value if you had linked to a video about this particular part, or explained what the machining challenge was, what the original cutter(s) were, why the original cutters failed, why the new cutters were better, and what you learned. So many educational opportunities missed here, but at least you stressed the importance of keeping records. I'll tell anybody the most important tool the shop is a notebook and pen. I say "Making mistakes is how we learn, repeating them is how we fail." Because in machining, everything matters - the machine, the setup, etc., not just your cutter supplier. With all respect, the takeaway message here "hang the entire future of your entire shop on a single tool type (and reliance on expensive overnight shipping) from a single vendor, and just fly out for a meeting with them whenever you get stuck" doesn't really compare with the educational content of your other excellent videos. :-)
Titan! Would be great if in a future you can machine an iPhone/iPad frame/chassis. At least only with the tooling you have make an approach to the final specs, because they use some laser machining for making it. But would be great if you can make an approach on it to show to the industry that some metallic parts of high end devices can be made in the USA at a good price. What do you think?. Thank you Titan for al your efforts.
You commenters are a crack up. They will never show the machining for this part.
It's called "Export Control Laws" - basically a gag order, they aren't allowed to divulge anything about the part or its customer.
I'm a machinist for a small shop that does prototyping work for aerospace companies - super high precision work.
All I cut are the INCOs, the hastelloys, the A286s, the AISI A2's, the titaniums, the monels - basically the materials most shops don't want to deal with.
And I say that because of my years of experience, all the software's tool companies provide that these guys are talking about towards the end are worth DIRT.
Nothing trumps experience.
I had a representative from a major tool supplier in my shop wanting to show off a special endmill like this one, he tried to show us the Speed/Feed software they had. I saw the numbers and laughed "the tools gonna break in minutes"
- it broke in 2.
Never trust those softwares.
I run 718 inconel and we use roughing mills aka hog mills. Don't know why Titan wouldn't.
I had the exact same thought? Why use such a flimsy end mill
No idea. Pretty strange to me. We use roughing mills in everything we do, even aluminum. We can get through 10000 parts EASY without worrying about degradation of our finish mill.
Great information. Would love to see it cutting a part. Thanks
He has plenty of vids where he cuts inconel with this tool
Hey titan, I know it’s not your style, but I think it’d be pretty cool if you did a “budget desktop cnc” where you’d use 1.5-2.2kw spindles and see how hard you can push those things. There’s really not too much info out there on home built CNCs that are cutting steel. This Old Tony has some videos on it but it’s not too expansive or in detail about his gantry or spindle yeti.
Anyways, great videos man. I don’t even run CNCs but I still love watching your videos.
I am doing some Tormach videos to show the entire spectrum
Likely need to use a water jet or some type of electrical discharge machining to really bite into that material.
Cheers boys!!
Man, i actually wish these kinds of materials would show up more on my table. I remember my first time machining Inconel 625, that was quite the experience! I will always remember what my customer told me: "If you can machine this, you can machine anything!“
That's what i work for, i want to make my customers proud with my work!
Possibly a dumb question, so pardon... I've never run a machining centre, rather I program a turret punch press and a laser profiling machine - so I love CNC. But if a tool is so expensive and has a defined life, wouldn't it be smart to stop using the tool before it catastrophically dies, and program in a new fresh tool to take over, thereby not stopping the job and work-flow. Maybe, because the tool is not completely dead, the used tool can be returned to the manufacturer for refurbishment, saving $$$$.
Sometimes it's worth the money to regrind but often it isn't because the more edges they need to regrind, obviously the more it will cost. Regrinds rarely last even close to the cutting time of the original tool. Probably due to heat stress, deflection stress and they don't usually re-coat the cutting edges like the original tool. I'm betting it's not cost effective to regrind a 6 flute endmill , especially if your only getting a half life because replacing the tool and restarting the job in the middle of the program is also a lot of lost time. Time is money in a production shop.
kennametal is in my state. love pennsylvania
Maybe you can try our endmill. Test on inconel 4099 with constant milling for 6 hours.
How do you think it would cut into cobalt chrome. I go threw a ton of 3/8 endmills when im roughing. Id love to get something that wont break after 10 parts.
Have you ever tried milling in hardox 600 Steel.
I use MachiningCloud instead of Novo in There are also many other retailers a Kennametal For example seco, Walter, ISCAR, Paul Horn GmbH, Tungaloy's, TaeguTec, and many more
No I haven’t...
Sounds Hard:-)
Machine Haynes188, A286, Monel, Inconel etc... Nitronic, TI, 15-5
Only $2,000,000,000 per endmill. I can't even imagine how much this endmill costs. I looked at a Kennametal 1/2 dia endmill for profiling aluminum, 1" flute length. It was $600 per endmill. I could buy data flute endmills that probably work better and cost WAY less.
Hi Gents what feeds and speeds would you recomend machining D6a at 45HRC. Rock drilling tools aplications on 5th axis victor ax350.
Titan, This might sound like a silly question but did you drill out most of the material first? one thing I really hate doing is drilling heat treated material but maybe you could drill it out before heat treat?
This is smart at times... but not for this application.
@@TITANSofCNC Yes that is true, Sometimes I make the mistake of commenting before I see the whole video, The point of the video was to showcase a amazing endmill, what was the rockwell of that material?
I gotta alot or respect for what you are doing with your academy and inspite of the fact that I have been doing this for a while now I usually learn something new from watching your videos thankyou again for uplifting precision machining and bringing it into popular culture. in the early 2000's one of my mentors was joking with me and telling me that I would be the last american machinist, a scary thought (which is something that is not entirely crazy). Titan keep fighting the good fight for us and hopefully I will see you someday in the future at IMTS or Westech with some new Guitars and Wallets...
Titan, what is the hrc of the inco? Have you tried YG-1 mills with nACo coating?
Kennametal Novo also works in metrics? Because for a lot of us users those freedomunits are just: "Erm this chipload is 4/780 footballfields long and u should use 165/32 beerkegs of feed"
Everything Kennametal knows about end mills came from me at Hanita lol. That's right.. 20 years ago. they called it the VARIMILL
A message to Titan, hoping this reaches you.. My name is Tyler Rook and I'm a machinist. It's in my blood and I live, love, and breath it. My grandfather started and grew a somewhat widely known company called ATS Workholding, but for reasons too time consuming for me to explain at the moment he no longer owns that company. So since 2009 or so he has been running an aerospace job shop. Fast forward to 2015, I packed up everything I owned and moved from Iowa to SoCal to work for him. I already knew how to make good parts at this point and could read code like I was reading a book, but I didn't know anything about how to program with a software. So I found a local MasterCam class and was instantly hooked and excelled far past my classmates. My grandpa has great relationships with tooling reps simply from doing this for so long, so we teamed up with some great reps that knew their shit and started kicking ass. My grandpa's niche was already hard metals, I couldn't even estimate how many hundreds of thousands of parts I've made out of 625, 718, A286, some monel, and some hasteloy. The point I'm trying to reach here is that I've never met or seen anyone that I feel has the same amount of love, skill, and drive for this industry until I started watching your videos and the dude from NYC CNC. And I believe that people like us, working together to teach other shops how to run as efficient as possible all across the nation could potentially help America's economy immensely. If you would be willing, I would love to come visit you sometime to talk about how I can help do the same thing you're doing. I want to educate people and do it the right way. My email is tyler.rook@yahoo.com I really want to make a difference!
Tyler, that’s an incredible story. Love your passion. It definitely takes an army to bring change and I am working to do my part... Speaking Boldly and Fighting for it.
Are you part of my TITANS of CNC: Academy Private Facebook Group?
That’s a great way to start...
Hey Titan,
When is it smart to use an insert cutter instead for this type of application?? It sounds like never might be the answer.
In this Material... it’s almost impossible to consistently cut with regular inserts... and if the inserts go your liable to drag the holder into the material. EndMills break off easy and last long.
Ceramic Shell Mills work well but you gotta change inserts often. 12-15 min
Hey TITANS. Did you work with 2.4610 (Hastelloy)? I would like to hear your experience about the material.
Will make a video
There are constant advances in cutting tools......keep looking at the new stuff and always go for the FREE DEMO
Why are you running your tools to the failure point? We always set tool life to pull the tool early and send in a fresh horse. It's cheaper to have a tired tool resharpened than breaking them and then replacing them.
ten littleindians
If it survives through the whole roughing process, it’s cheaper to just keep it in the machine as opposed to stopping the program, pulling it out, putting a new tool in and starting again. Making the parts faster will make up for the cost of the tooling
Could just have a duplicate tool in the carosel. Tool change at Line "x" for duplicate.
Eluderatnight they could buy guessing that don’t have big enough tool changer
@@ardimarcs7698 Clearly you have never priced these end mills. Even if they have the tool capacity filled they could have another in a holder on the bench with it's information loaded into another tool offset slot. It takes less than a minute to manually swap the tools and call up the offset for the fresh horse. While the tool is cutting away the operator can swap out the tired cutter and measure it on the presetter and enter the data into the machine. Even on a machine brand that won't let you adjust offsets while it's running you can still right down the numbers on a piece of masking tape and stick it on the tool so they are handy for entering later.
@@Eluderatnight Yes, that's the proper way to do it in many cases.
is Maraging steel 2800 more difficult to work with than Inconel 718?
What if your electricity was free to you and you have foundry as a part of your operation? How much would you save then? I'm serious about the free electrical!
Verry good brother booooom 👍👍👍💪💪💪💪💪😍
Titan how about Rifling by Flow Forming some Military Tank Barrels using a material containing 50% Cobalt ? Can you image the size of those 3 rollers applying the pressure. Titan, invest in Stuart...going places!
What ae ap would you commonly take with this cutter in 718 ?
boooom man your the best
Another great video, thank you guys for putting this out for us to keep learning.
If I had a part that kept breaking endmills, I'd think about running that part on a different machine to see if the machine is the fault. I'd try a 50 taper and see if cutting tool life improved, if it did, then I'd say it was my tuning fork of a machine that was the root cause of the short tool life.
Try really slow speed and really deep cut depth. Any tool gets it done brother. You've got to get under the hard surface from previous cut.
Did you try some of yg-1 endmills? We use the x5070 to cut up to rc70
Love Yg1s tools. For Ti and Stainless
Especially their XPower series. Their Jet Power fine roughers are amazing. But for Inconel not so much.
@@pakman422 had really good luck with their TitaNox Power on stainless. Getting 8 times the work done VS the imco's I was using previously.
My shop gets cloudy from coolant...do you guys run any type of air filter system...the older people swear it's not safe to breath...company swears its fine
That's crazy!!
And one more thing can this tool use for i machine vk 2
I jst started working in tool mgf small scale industry I want do carrier in that which thing should I learn???
I by this tool, but for Bolher k346 it’s doesn’t work. After one pass all the Harvey III break. So I changed the tools to a rough edge tool, the cycle time is longer but I can make 8 cycles of 2 pieces or 16 pieces.
Do you guys have any manual with further details on machining such materials??
Zombie mill! Dun dun dun... savage.
Good tutorial
Hey dear friend do you knows where can I find a some links where I download diferents endmills yo my projects
Hey titan we at roseville high school cant find the right post processor for our haas TM1P and we cant figure out what the right type to run on our simulator
