You are the reason why I push my machines at work. I love the job and industry. My father is who taught me and he is a great machinist and I hope to be half the man he is one day. But I have made him come out of the old ages and run our machines like you do. It’s so cool to see a wall of chips blasting the door of the machine. I reprogrammed a part that I did 4 years ago after watching one of your videos and it was a 28 minute run. It’s heat treated 4140 and I got it down to 11 minutes just by trusting my tools. I about fell over with how cool it was to was heat treated material just fly off like it was nothing.
Impressed, in my shop that sound would have 15 fellow workers standing there watching awe struck me included.
Titans of CNC ROCKS! I love to nerd 🤓 out with these videos!! This trade can be awesome!
PLEASE put metric conversions on your videos :)
BOOM!
We are coming out with Metric prints for our Academy and will soon start adding metric in addition to imperial

@@TITANSofCNC Thank you so much. It would make it more instictive for us Europeans! :-)
@@TITANSofCNC So you finally connecting to the rest of the world :=)
Breaking all the rules of machining and extending it to the maximum! 🔥🔥🔥
Wow, this demonstration was so impressive, the precision of the machines and the cutting ability of the tool is extreme, bravo.
I love these kind of videos! You guys are definitely pushing machining to the max!
4:50 onward mind blown !!! Alien technology.
Love what you are doing with CnC's and new cutters. Suggestion:
Where is the new tech in precision surface grinding? That might warrant a video...
Great job Titan. Awesome to see you, PowerMill, DMG MORI, and Kennametal combining to deliver the goods
I ran a dmu 80fd for about 6 years. Those machines are so sick.With a heidenhain controller makes it easy to run and program. One of my favorite machines. I miss running it. For the last 5 years it's been nothing but fanuc, hass controls and programming with mastercam.
Would love to see a video on pushing a 3/4" Harvi III in some 4140HT
This is insane. Im a cnc programmer and watching these videos makes me try things in my programs that i ordinarily wouldnt try.
I just started a week ago on an old miltronics VM20 and the first job they give me (fresh out of my second semester of "machinist college" with my only experience being in aluminum and delrin) is to cut 24 parts out of 304L stainless. Oh, and the biggest endmill I can use on the finishing pass is a 1/4 inch. I've busted around 10 endmills from bad programming mistakes so far. Trying to go a week without breaking any
So when I was watching I was thinking “yeah I guess that’s what the limit for what you could reasonably expect would be, but what if it was possible to do something crazy? then BOOM! My jaw dropped when what I thought was crazy was a tame version of what happened! I had no idea it could do that!! Kennametal is a beast!!
Beast mode enabled. Damn, that's impressive. Those rates are insane and would have taken out most carbide mills that size as soon as it engages. WOW...
Let's see some videos on how to get incredible surface finishes.
@@spikeypineapple552 Thanks Samuel but I doubt seriously that all metals use the same formula. What is the best tool holder? Should you dial in your tool first? Better to use high flute count or low? Talk about deflection and how to stop or correct it. What about face mills? Diamond tipped inserts? Aluminum? Copper? Mild Steel? Hard Steel?
In aluminum use a 45deg helix cutter. The tighter the machine the better the surface finish it will get.
what? are you crazy? not at Titans ^^
@@jdholbrook33 Most of these questions depend completely on your part, tool, and machine. All suggested speeds and feeds are just a starting point. Use your cutting feed dial and spindle rpm dial to fine tune the cut as its milling, make note of the speeds and feeds and use that for your next program. And as far as tool holders, always use a solid tool holder for endmills if possible. Yes, dial in your tools, or at least check the runout first, that should be done quite often. Aluminum, finish with a 2 or 3 flute, Mild steel and hard steel, finish with a 4 flute. Typically, you want to go slower with the rpms and feed rate when running your finish pass, surface finish dosnt really mater as much in roughing passes, you are just trying to remove metal, not make a pretty part when you rough out stuff.
@@r0cd0x Thank you, very helpful.
The present: How to NOT break the TOOL. /// The future with Kennametal: How to NOT break the SPINDLE...
Amazing precision speed and cleanliness of cut
Impressive and great to see believed boundaries moving :)
And thanks for explaining MRR I asked about that after one of your recent vlogs.
I've watched all the videos on starting up a CNC Shop they've been awesome ! I plan on starting my own CNC shop in a couple years wondering if you could talk about "how to think" and "what to consider" about the first CNC Machines to buy how to calculate how many machines , how to know when to upgrade to more machines. I need more insight in the financial mindset of starting a shop and not overspending at the start.
Thanks,
Boom!
I've ran several CNC mills in the past but that feed rate is just insane.
Titan of cnc your the best. I hope i can work to your company someday. Right now I'm practicing every technique that you doing in your TH-cam channel. CNC MACHINIST FROM THE PHILIPPINES. THANKS
Cool machining test, I like that some of the part was 3D and your toolpath did step up machining. Thanks for pushing these tools. Maybe do some videos with 40 taper haas and ER collets, because this is what many people use. Or some simple shoot out videos 40 taper ER vs Hydruallic vs Weldon Flat? How to get the best out of what you have in the shop kind of stuff.
I have no doubt in their ability but I do find it interesting the Haas is hiding on these.
Haas has its limits. We have stalled the spindle on our HS-4 (50 taper horizontal mill w/150” X and 66” Y travel) trying the same cuts that were no problem on a Matsuura. Shows the difference of power some tools have over others. Also the price tag reflects that lol.
Usually I slow the rpm down when helical ramping and when it hits the bottom I speed it up to max rpm. Idk if you did that because the spindle sounds so nice but it helps with tool life a lot. I've never had something spark like that in 1018 while ramping and have long tool life. Also ramping outwards from the pocket you have a larger chip load. That might be why the chip were the nice blue color instead of yellow like the outside profile. That makes me think you could probably go even faster with the feed on the outside no problem.
Titan, thanks for putting these videos out. My passion for the career I love is slowly dying out thanks to the company I work for, and every time I see something awesome like this, it reignites that flame.
Titan You blown my mind inside of the pocket!
That's just insane! 😍😍😍
Hi Titan, great videos man! Really appreciate and enjoy the infotainment you gives us all. Wanted to know, are you using the recommended Feeds and Speeds from Kennametal and/or your own experience and knowledge to achieve this? Great job 👏🏻👏🏻🙌🏻😎
3:29-4:30 literally SHOWS ON TOP OF THE SCREEN THE FEED RATES USED FOR THE VIDEO.
Does a voice over explaining he is CHANGING the RPM from 15K to 19.6K RPM.
Changing Z-axis feed to be higher. ( I don't agree with this completely because his only Z-feed was when he made the plunge for his pocket and the chips could not hold any more heat.)
Changing Radial depth of cut to be less deep because the spindle speed is higher as compensation which puts less pressure on the tool in the weakest direction of force.
SMH.
This is a 2 year old post.. hope you are 2 years wiser.
Wow that was beast!
I would like an in depth* video series that tours DMG mori and shows us what they put into making their machines the best in the world.
Can't wait to try this on the bridgeport on monday
Those were some "Hot Chips" Boom !
Great video Titan i would really like to see videos with this Harvi 3 endmill running in the Tormach 770 as i own one myself Thanks
awesome video Titan!
quick question. how do you like the HSk type of holders over the BT types? used to run hsk 100 at my old job. Kinda miss that.
It's really good to see how the tool is designed to take the heat away from the cut in the chips.
unfortunately the tool cannot take the heat from the chips piling up in the pocket.
Love that ring after cuts
I would like a video series that tours DMG mori and shows us what they put into making their machines the best in the world.
Awesome video. You should also talk about the holder used with the cutter. I notice that this holder is the Hydro Force which is a heavy duty hydraulic version. I assume you have air thru spindle and the collet slots? Have you tried other hydraulic holder brands like Sandvik or Schunk?
Thank you Titan!
Awesome once again.
An awesome exercise, Titan (and fun to watch!). But at that speed, is there any risk of heating the workpiece to an extent that it could affect the metal? Not that you'd run a critical aerospace component that fast ... but if you had to do a million, and the part was small, might it stress the steel?
Titan, love your videos, you are dead on right. Smarter manufacturing is what will put the U.S. back to a self sustaining economy. We are to the point where 4 man shops can kill it in production and quality.
MEADS miniaturization, education, automation, documentation and standardization
We are at the edge of the next industrial revolution
CNC is just a robot. After I get my first VMC, the next piece will be a loading robot, even if I have to do a self build out of OTS components. I would rather pay people to maintain and program robots than to pay them to stand around loading parts and hitting starts.
I was run over a month ago in a parking lot, crushed ankle. I have a small garage shop. I was 2 weeks away from pulling trigger on haas TM and CL machines. Work lined up, projects planned... I am now to where I can stand for a short bit (10-15 minutes max with crutches) and work, so I could load parts and do slooow set-ups on cnc or manual, but I can not stand to do manual runs. My 17yo son is learning, and autocad certified, but school is priority. After multiple surgeries installing external and internal hardware, and doctors visits the bills are starting to come in, and it will affect everything. Available cash, future earnings, credit, work flow, customer relations, family stress and everything else. My point?? Had I Just got the machines when I first thought I should, first part of January, instead of waiting till April, for no other reason than a little scared of what ifs, I would be OK. Behind, slow, stressed, but it would have been fine. Don't be scared, take the risk, MAKE IT HAPPEN. DO NOT WAIT FOR IT TO HAPPEN, MAKE IT. This poor timing on my part set me back close to 2 years at best the way things are looking, and it hurts. I'll keep at it. It will happen.
Just try free of charge education (college, and university). That's why the Titan is using a German machine and German utilities (vices, chucks).
Better education leads to better results (and requires less expensive supervision).
OMG.. Really blows your mind what that tool removes its against everything you learn as a beginner but it works and that's what counts 👍😎
It works, but for how long will it work.
If it costs half as much as the competition, but only does 1/4 of the parts as the competition. Its not economical.
@Frauenarzt Dr. Stefan Frank there is a point where profit and loss cross with machine wear and tool breakage and downtime re setting up tools.
Some small endmills depending on how new they are and what coatings they have can be extremely expencive.
I realize you are running w/o coolant for the video and possibly for the testing but could you do a video on the importance of proper coolant usage and maintenance. Thanks for the video post and what you are doing to promote knowledge and education in our trade.
th-cam.com/video/5FloZrOoEBg/w-d-xo.html
you'd probably want to run this without coolant anyway - in the inside pocket you'd be re-cutting chips for sure, if you have flood coolant those chips will be hardened from the rapid cooling, which in turn can be a lot harder on the tool.
@@TravisHammeng Thanks for your Input and reply. That makes since with this particular operation and the amount of material removal. I know some tooling coatings of today actually work better w/o coolant. As with proper tools, feeds, speeds I was curious as to different application for "flood, mist, airblast" per material and rate of removal. I know there's lots of variables. Probably enough info for a few videos. Thanks again! 👍
I need one of those cutters! Not sure what for but it's impressive 👍
EVEN MORE INSANE!
😊 this is what I like 💪💪💪
This is pushing limit test, great.
It's a very nice tool Kennametal HARVI I used it very much in a ER32 clap with Safe-Lock It just works
Yep, Harvi 1 has 4 flutes... this Harvi 3 has 6
Great video - I would like to see a video on surface finishes, and more so, diagnosing how to improve. For example, how the surface looks when you go too fast, or so slow, etc.
Greg how it looks when you go to fast.... look in this video 😂😂😂
@@per.kallberg lol, totally. The vertical lines are the sign, but it would be great for titan to explain it, he's the master
@Frauenarzt Dr. Stefan Frank Please bro, you're an actor on a TV show.....lol
Hey Titan i see you have the siemens control do you have any experience with the command "brisk" it basically accelerates the axis faster and is very usefull for dropping machining Time.
In the manual they say that it is hard on the mechanics.
My question now is: how harmful can it really be?
Wow.. I'm a chicken sheeet lol.. this part probably would have taken me a couple hours to mill, granted I'm on a vf2 with standard end mill holders and a 10k spindle, and this is a mori with hydraulic holders etc.. still I've never pushed anything even half this hard on steel.. I've gotta step out of my comfort zone. I would venture to say 10 years ago, this would have just come across as reckless in any shop I've worked at and maybe even gotten a machinist sent packing, but you are showing what these machines and tools can actually handle and are designed to do, very cool stuff Ty!
Would it possibly be advantageous to put a robot arm into the machine cabinet and have this arm work in tandem with the cnc programming to vacuum up chips?
Theoretically the arm would always stay out of the way of the machining heads, since it is aware of the tool path.
Would this approach help productivity?
Also, couldn't you get better finishes if chips are quickly removed?
Maybe even use a wet vac when coolant is on?
Did you goes get the rapid turn attachment for your Tormach 770m+. I would love to see the rocket series done with that.
Are you sponsored by kennametal? The reason I ask I would love to see you try out some of Niagara cutter's tooling. I've had excellent results with the stabilizer series tooling
How much higher than 40 would the MRR be at 4:50? With feedrate, RPM and stepover the same, feed per tooth increases a ton in internal pockets and corners. That's why we see a lot of blue chips when the pocket is small, then straw colored and back to silver as the pocket opens up.
Running at this speed on this same exact part how long will this tool last ?
bestial, incredible, what else to say. Titan the best 💪💪💪
TITAN! Could you up the rate even further by using coolant or is the tool right on the edge anyway?
Titan, which ball end mills do you recommend for 5 axis machining steel and aluminum?
Is there a reason to only climb cut during those passes? I know it results in a better surface finish, however, that does not matter during roughing. The cycle time could be reduced by a third if the cutter also conventionally cut to avoid those rapid feed times that otherwise could be used for cutting material.
Wow! Just goes to show Kennametal is really putting some quality time into making their tools 😺.
There is something I'd like to see as I am considering getting that coolant that you use and that something is, "How fast can you cut into Delrin/POM/Acetal materials using that coolant without it melting on you and snapping the end mill?" Now I normally use Harvey Tools for cutting these plastics and would also like to know if Kennametal has some really good plastic cutters that allow massive material removal rates without melting the materials?
@Frauenarzt Dr. Stefan Frank Thanks
Beautiful!!
Tools of Domination
That's certainly an eager little bit. :D
thnx for the blessing
Just tried to kill a 1/2 Harvi 3 in hardened D2 ( 62Rc) that SOB wouldn't die ! ! thanks for the PROMO !
Can yall create a nice aluminum topographic model.
Wow!
That’s insane
Omg nice feed i need Sony of them. I will test it in Our company.
@4:30 like … NO WAAAAAAY ! Awesome ! Serious question @TITANS of CNC: Academy running at 19,000 rpm can you say something about tool balancing ?
Most of my vendors really press that one even for HSK 63 etc. and anything in the 15K to 20K rpm range ? [I think DMG are getting their money's worth now lol.].
@Frauenarzt Dr. Stefan Frank Well Titan has his DMG Mori 3rd gen DMU 50 , with Mori Seiki 20K rpm spindle. And NYC cnc / Saunders machine works has a tool balancer a UMC 750 (HAAS) of some sort and a new online program he is rolling out for feeds and speeds... So maybe "Awareness " is changing a bit ? @ Dr SF good comment about "Everything above 12K rpm " (including even HSK-E ). Cheers !
That's impressive stock removal
@titansofcnc can you tell me the article number of that exact end Mill? I would like to order some! Thanks in advance
Siemens controller, aaaaaahhhhh!
쌉 미쳤네... 존경합니다. 형님.
That is just perfect! How much HP would something like this need?
This machine has 40HP and we were up at 60%
My point is just to show it’s possible so others can test their own boundaries
@@TITANSofCNC Yeah, it's all about getting perspective. And you really shifts the view on every video!
You should put video with metric units too.For Europe.
Those Hatvi 3s will cut with basically no cutting edge left. It is almost unbelievable.
4:50 !!! sure impressed by the tool's performances in sort of "kamikaze" conditions ignoring tool durability , but even more impressed by the machine fluidity ! & by the way did someone know a kind of high performance endmill 7/8 (.875") with a cutting length of 3.400" to be used in 4140 steel ???
(3.380") it's the depth of final cut. but it can be done by step, maybe with a "recessed neck" solid carbide endmill I guess... let me know if you have any suggestions !
Terminator!!!!
Is the MRR accurate only with 100% end mill engagement on the steel. If the tool engagement is only 75% and 25% is cutting air is the true MMR only 3/4 of the math.
Steve
When he says "radial" he means "radial depth of cut", not the tool size, so if you're hitting with the edge like in the video, it's 0.041" (like he was using), but 1d slotting would be 3/8" for radial
Mi pregunta seria
Que si una hass mini mill podria trabajar asi
Con la misma herramienta
This is killer.
If you really want to do a test to maximize MRR create a part/toolpath that avoids all the unnecessary rapid moves. Take the rectangle and keep crushing it without any rapid moves until you reach a full minute. That will keep the tool engaged 100% of the time which will maximize MRR for a true test. Obviously some parts require the rapids, but for a test part to test the Zombie's capability go full out cutting. You may see 50+ ci/min.
waooooow . unbelievable ............................Boom
can the public come out to your shop. im in fort worth an would like to learn some stuff
Boom!
Carving into that hole was unbelievable! BOOM. 😲
I noticed that you almost never use conventional cutting. I would consider a "Both" direction tool path. Why do you not use it especially while roughing?
Or maybe pocket mill the outer roughing? That way it would mainly mill in the same directon all the time but always milling steel. Just a thought
Can you show me, what High speed settings - CYCLE832 do you use for this?
What type of holder did you use
What were the spindle loads percentage-wise maxing out at whilst doing the heavier portions?
60%
Got knows how those cutters stand up to the workload you put on them..
I think that it also helps to have a $500,000 + machine to run it. Make a video of this pushing a HAAS to its limit.
Speed Metal!
Fun starts at 4:50😍
Wow.
Wish that you posted metric numbers too. Hate pausing to get the calculator out to work out what your talking about. But how are you running the surface feet so high past the manufacturers recommended speeds. Cutter should burn up no?
From a guy that came from imperial to metric, I will say metric,is much easier, I just use 25 as a reference to convert. Its 25.4, but maths am I right...So lets say hes cutting at 100 Inches per min feed rate that would be close to 2500millimeters per min same thing with dimensions. 25 microns is about .001 or a "1thousandths" of a inch.
Coming soon
@@brandonemmons2193 the maths not hard. More i just want to see the numbers instead of working them all out
Usually mfg recommendations are starting speeds and feeds. Conservative. Run it baby!!
What was the rockwell c hardness of this material?
