Love Seeing Tyson Having Fun… Truth is, the cuts he took were 4 times faster than the parameters given with the tool / insert… So he definitely was testing the boundaries… and holding his breath😂… On that last cut, I told him that he should actually turn away from the machine and just have his hand on the STOP… as his ears would hear the insert go quicker than his eyes and he would be faster hitting that red button… of course he needed to see the CUT, but to our surprise… It just literally Zipped right through it. WOW! This tangential insert is truly… a Remarkable BEAST! Great Job Tyson!!! - Proud Dad
Tyson has really upped is game! Great video however I would be concerned with the b Axis alignment after so much heavy roughing…. Best practice to use the lower turret for the heavy stuff. IMO.
That's insane! What an incredible tool! And the claw jaws did a great job of hanging on. Would be very curious to see the spindle load and chips at each pass!!! Obviously spindle load will decrease at the lower diameter, even with the increased data.
Would you guys ever consider doing a couple videos showing how tool wear varies across a bunch of parts at different cutting parameters? I know it’s not as cool as pushing to the max, but from an education perspective it would be good. Shows folks more of the “long game”, which is where the money’s made.
I second this, a LOT of shops don’t put aside time to test their cutters and fine tune the SFM and chip load depending on X number of variables. I would love to see anything that involves examining tool wear at different combinations of conditions, one of my last shops were anal about it and it was awesome.
@@mrblue747 Would be cool info to see for things like lights out machining or automation. Better to go a bit slower and have a rock solid process, but how slow is the real question. It’s one thing to cut a part 30% faster, but it’s no good if you’re changing inserts/tools twice as often.
I third this. I'd love to see a detailed enough video about tool life on different kinds of tools with different feeds, speeds, DOC, LOC, etc. in a given material. That'd be VERY informative!
Oh my goodness!! That tool is totally insane!!!! I had to rematch that last cut like 6 times and I can honestly say that my mind is now blown!! Thank you titan and your team for being so professional and on top of your game
Why didn't you just use G0 and 25% rapid feed? 😂 I would've liked to seen the spindle load meter. I've done cuts like that on cast iron, but it was 100HP main spindle with a 24" chuck. Most jobbing shops the lathes are 20-30HP max.unless you have a job to run a big production part or like the shop I was in we got a good deal on a used machine. You Titan guys are spoiled. If the insert is made to handle that depth of cut and your machine has enough HP do it The feed .024" okay, but 1000SFM in 4140 Damn!!! That's a little scary 😁
OMG that last cut was absolute Insanity! Must also give credit to the Doosan for having the power and stability to back that new insert at those rates without chatter issues.
I saw the specs and pricing on some Doosan machines, and for example their entry level VMCs that go at a smidge above the price of the full spec'd DMG M1 I worked on, is literally better in almost every way in terms of performance, and at least equal in terms of capacity with the exception of the square working envelope of the M1, and the head-head-head kinematics of the M1 that mean it has no way covers below the spindle, which makes running it and cleaning it very quick and easy, and you don't get any chip jamming issues with the way covers.
That was crazy, 😧😎it would have been interesting to see the chips from each pass. Thanks for the video. Incidentally something that has always bothered me is the heat being produced and the heat in the metal, especially at high speed while using coolant or is there very little change.
Which metal are you asking about? The material being cut or the actual machine? The material heat build up is pretty minimal even with the machine and coolant getting up to 150°f. The chips are coming off so fast that the part doesn't really have time to heat up the mass of the slug he is machining. Also when you use HP coolant you create a cooling effect. In the piping and tool it might be 100°, but when its spraying like that it drops to like 50°, hits the part and hot chips, then gets heated up to 150° and then will dissipate heat in the coolant tank, chiller or machine itself. Combine that and the tool geometry to remove chips that fast and you got a rockin set up. These are just arbitrary numbers, but hopefully that makes sense.
Also, the chip would look kinda stepped/jagged on one side and smooth on the other and from the sound of the chips in this video I bet they're a nice dark gold
My local Kennametal rep has been bugging me to try these out. I look forward to seeing how it stacks up against the Iscar COMG646 inserts we use right now. Running it on the 100 degree edge we can take a max DoC of .415 at a feed of .024 maxing out the spindle load at around 90%. If we drop the DoC to around .300 we can push the feed up to .034.
Damn that's some insane cuts, definitely fascinating. I currently run a Puma SMX3100LS. Wish you guys would show what the Load Meter looks like when doing stuff like this. Big ups to all the Titan team for providing great knowledge on this channel. Shout outs from Houston, TX ✌
Kennametal has had this type of insert for ages, worked with those some 30 years ago on a manual lathe.. it is just incredible what you can do with these inserts, and they only got better through the years.. And you get 8 cutting edges per insert.. how' s that for return on investment...
It's fun pushing the limits and seeing what the tool and machine are capable of. Really wish that you could've had a PIP of load meter so that we could see how much spindle and Z load it was taking.
Ok, idea time. Great video and awesome job here. BTW, you guys are absolutely nuts! I would definitely be worried about damage to your equipment. Here's my thoughts: 1000 psi coolant pressure makes absolute sense here. Consider what a water jet cutting machine does and apply the cutting tech/principles to this situation. Bump up another coolant stream to steel cutting pressures, aim the stream above the cutting tool and at an angle if necessary and look at your loading numbers. If you can reduce loading and tool wear significantly then you will be in the money. As it is all by itself this incert is a game changer. If you bump up the coolant pressure to 2-3k and are able to cool the coolant down to negative temperatures Fahrenheit you might get even more performance out of this incert. Lots of different approaches to this and plenty more upside to production speed are possible. Great job guys!
I have a free pro tip when filming with such amount of coolant. Just use well adjusted air nozzle. You get your coolant just at the tip of the insert and the airflow deflects coolant away from the camera😎😎. You don't need to thank me. You do good job man. Keep doing it.
Used a version of a tangential tool years ago. Took 3/8 inch depth of cut on a old LaBlonde tape turn lathe. The lathe was a beast with super heavy box ways.
I don't know what tool we used 20 years back but our old lathe (it's just old, we still have it) got it's gearbox destroyed and the support flew off during similar cuts to this. i think 10mm radial and 0.2mm feed now this machine is not that precise anymore but if you know how to produce good parts on there you definitely can turn😂
Nice Video...Kennametal has a short video introducing the Carbide Insert...people were complaining it had no video of any cutting. Now, they'll be complaining you can't see due to the coolant spraying all over.
Having been a lathe guy for all of my machinist career that was both amazing and a little nerve racking! It's different pushing a lathe to the max. Well done Tyson.
LNMX is a good Insert for removing bulk like that too. And even though it was a small part it’s still surprising you could do that without a tail stock.
I am currently doing an apprenticeship as a toolbuilder but I want to become a cnc operator and move to the us. Here in germany the government limits the time I can spend working to "protect" me. Fuck that. Work is life! I LOVE these videos!!!
I remember late 90s boss brought a tool to us from Hertel. WHAT??? Tangentially mounted insert. Turning tool and a 4in face mill. Identical insert mount but no chip breaker. We used to HOG 4140 with that facemill .300dp and .01-.015/tthor better for other material. Just lower speed because of HP. Still a killer design as witnessed here. Never broke an insert, just got the coolant boiling in the chip tray. Oh ya, no robots involved or shields to hide behind 😁. Just you, a mass of steel, and a scoop shovel to move the chips.
Right. Each cut, the part diameter is smaller, and with the same or faster SFM the RPM increases each time, and then he increased the cut per turn also. So it is running 2550 RPM, .024 per turn, 61 inches per minute tool movement, and only 1 second per inch of travel! At 1000 SFM = 12,000 inches/minute, .024x.400=.0096 cross section area, that is 115 cubic inches per minute of steel. To support such cuts you need to be cutting a large block of material, a smaller rod would collapse with that much force applied.
Amazing tool. I remember getting similar output using CNMG120412-PR from SANDVIK about 15 years ago on old FNC 1500 Lathe. I think it was 9.5mm depth 0.8mm mm/r and and speed was around 700m/min.
That's all very nice. It is. But, for my money it is the ability to hold tight tolerances consistently. So mic it, then set a depth of cut take a pass, and mic it again and see what you can hold. The tool and part deflection at different depths of cut and different diameters would be interesting to see.
I still have a couple of boxes of Hertel FixPerfect inserts that I reserve for finishing work. What I liked was they were sharp edged, putting very little deflection on the part, and yet would roll up a nice chip into a smooth spiral that would break clean, instead of forming a bird's nest and I didn't have to push the feed to get chip break, which is what you want when finishing to a certain roughness spec.
What is the spindle load? Those are some big cuts. I'd be interested in knowing what the spindle load was. You could hear the machine bogging down on that last cut.
I think what you hear is not the machine bogging down but the part's harmonics greatly changing as the pass is being made , like sliding a guitar string toward the neck
I ran a big 36 inch chuck on a belt driven lathe at my last job .040 per rev at .25 depth of cut no problem on 4140. But it wasn’t hardened or annealed . .050 per rev when facing
This is awesome and really like the new push on tools and materials. I would like to see more on the traditional materials being pushed to the max like cast iron or forged materials even cast like materials, maybe even plastics machined
Kennametal recommends a max speed of 190 meters/min ( 620 SFM ) for the product group you're in P5-P6. Why taking the risk to ruin your tools, chuck or machine by increase the speed by 60% further than the max. up to 305 m/min - 1000 SFM ??? Maybe you have to ask the guys at Schunk about reducing of clamping force at high refs and torque with that big cut.
Omg ...i geusing your tormenting the machine to the maxium bhp with that last pass , out if this world ! Btw i love your dad haha lol . Grtz from the netherlands Johny geerts
Man, that's a lot of faith in a piece of plastic and a bit of sheet metal. Like everyone else, seeing the axis load would give a better picture, but you just can't watch that many things happening all at once. 😲
Eat .500" of inco 718 in one pass and I'll be impressed. Has my CNMG's going that in a screw machine. And worried if the to can do it.? If your machine is capable why not?
It sounds good, but its a sound that i would be ready to turn bad at any moment. @ around 4:27 the smoke from the tool was massive. Thats a big working area of lathe full of smoke
If you're cutting on a reducing diameter, wont you be removing less material per unit depth of cut? So it should be easier to take deeper cuts at smaller diameter even with same surface speed and feed rate.
Impressive how that top spindle holds its position under that load ,does it hold its position via mechanical lock or electrical hold not loosing steps ?
I really don't see why these guys are so obsessed with nearly destroying tooling or deliberately breaking cutters, and what wear damage are their machines being subjected to over time?
That's alot of 4140 - 1/2" inch at those feed rates to remove. Wow. Curious to the cost of the inserts and how long they actually last feeding it even 80% as hard as you just pushed it. Cost to cut ratio matters most.
1000 SFM, . 024" FPR and 1000psi coolant was it enough not to have made any heat to work harden the 4140? The higher feed rate is smart, because you want the heat in the chip A lot of machinist would make the mistake of lowering the feed, but that would generate more heat. It's scary af and operators always want to slow the feed, but that would work harden the part and the next cut will break your insert. Correct me if I'm wrong.
What I also saw is that you didn't face off the face before the cut! I believe the un-faced rugged face have impact on the start of tool-material engagement. You should face it off next time. Thank you.
@@littlejackalo5326 I believe is has. Just make a try of even a small one. I have been in that situation a and when it goes beyond 100mm diameter I face it off.
Great video showing how to find limits. Also i think if you have the same machine at home....why not try at home but approach it gradually as you did. Great job!
Hey hey you! It is only when the insert break off or become overwhelmed by the chip load and the chips starts self welding to it then I back off from being aggressive. That tool, that machine, that insert can still go bigger than it is maybe the full insert width will limit it. The last 2500 rpm sound great and yes, could give you a sweet spot for the chip load. Just cool though.
Beyond impressed blown away wow. Question the coolant Blaser Synergy what concentration in machine and also what concentration in the recharge. We used 7 percent and 1 1/2 percent in the recharge in our Blaser.
nice video! you should try SMG 1115 or the Kendametal Spat MD ive been using this insert for years and easy cuts @.480 - .500 per side and at 15in length of cut.

theyre at the upper limits of the machine and tooling doing this, spindle load would have been 70% or more on the first few passes

You are a wild and crazy guy living on the edge like that .
That is completely insane! Have you tried having compressed air blowing on the gopro to film with coolant on? That would ruin the sound though
This makes me think of an old saying I once heard. "A dog that pisses hard, doesn't piss for long" 😊
That’s incredible how fast it chewed through that, and that last cut really surprised me how fast it zipped across there, that was really impressive!
Right. Each cut, the part diameter is smaller, and with the same or faster SFM the RPM increases each time, and then he increased the cut per turn also. So it is running 2550 RPM, .024 per turn, 61 inches per minute tool movement, and only 1 second per inch of travel!

Finally some metric specs i can handle.. i was like 500 000 per side what?! 😅
That's all very nice. It is. But, for my money it is the ability to hold tight tolerances consistently. So mic it, then set a depth of cut take a pass, and mic it again and see what you can hold. The tool and part deflection at different depths of cut and different diameters would be interesting to see.
Looks like the old Hertel cutter, it really performed well.
couldn't remember that name but I used those tools almost 30 years ago, 8 corners and very strong insert.
I still have a couple of boxes of Hertel FixPerfect inserts that I reserve for finishing work. What I liked was they were sharp edged, putting very little deflection on the part, and yet would roll up a nice chip into a smooth spiral that would break clean, instead of forming a bird's nest and I didn't have to push the feed to get chip break, which is what you want when finishing to a certain roughness spec.

I used to work with a guy who would take .300" depth of cut with a 4 radius turning tool, on a Tos manual lathe. No hydraulic chuck either.
It sounds good, but its a sound that i would be ready to turn bad at any moment. @ around 4:27 the smoke from the tool was massive. Thats a big working area of lathe full of smoke
I’ve done .300” depth of cut on a 32mm swiss lathe, but at feeds more like .0005-.001IPR 😅
You should show the horse power used and the chips
If you're cutting on a reducing diameter, wont you be removing less material per unit depth of cut? So it should be easier to take deeper cuts at smaller diameter even with same surface speed and feed rate.
Impressive how that top spindle holds its position under that load ,does it hold its position via mechanical lock or electrical hold not loosing steps ?
I really don't see why these guys are so obsessed with nearly destroying tooling or deliberately breaking cutters, and what wear damage are their machines being subjected to over time?
That's alot of 4140 - 1/2" inch at those feed rates to remove. Wow.
Curious to the cost of the inserts and how long they actually last feeding it even 80% as hard as you just pushed it.
Cost to cut ratio matters most.
1000 SFM, . 024" FPR and 1000psi coolant was it enough not to have made any heat to work harden the 4140?
The higher feed rate is smart, because you want the heat in the chip A lot of machinist would make the mistake of lowering the feed, but that would generate more heat. It's scary af and operators always want to slow the feed, but that would work harden the part and the next cut will break your insert. Correct me if I'm wrong.
What I also saw is that you didn't face off the face before the cut! I believe the un-faced rugged face have impact on the start of tool-material engagement. You should face it off next time. Thank you.
It makes zero difference. That took is so strong and the feed is so fast, that facing the part won't have any impact on anything.
@@littlejackalo5326 I believe is has. Just make a try of even a small one. I have been in that situation a and when it goes beyond 100mm diameter I face it off.
LOL Iscar LNMX22 !!!
That is speed and feed not this *********
O wow 😬 Glad I'm on this side of the screen. 😅
That's pretty impressive. I'll bet the light went dim in the building next door on that last cut lol
Wow!! That was a beautiful thing right there ... Absolutely amazing. Pushing the limits.. I wish I could work for y'all.
Great video showing how to find limits. Also i think if you have the same machine at home....why not try at home but approach it gradually as you did.
Great job!
Bro ... It slice like a potatoe... Fantastic..
Most aggressive that I have ever seen for sure. Would have liked to see a shot of piles of chips on table in order of cut or something like that.
Nice Cut Deep ...you must Show dry ships =)
Nice chip breaker on tip, it's the type of tool you can trust just like the look on your face Tyson NO PROBLEMO, Titan keep on Booming ON
Hey hey you! It is only when the insert break off or become overwhelmed by the chip load and the chips starts self welding to it then I back off from being aggressive. That tool, that machine, that insert can still go bigger than it is maybe the full insert width will limit it. The last 2500 rpm sound great and yes, could give you a sweet spot for the chip load. Just cool though.
WOW!
What are the axis and spindle loads like when doing these cuts?
Damn, bud. That was awesome. Thank you.
Beyond impressed blown away wow. Question the coolant Blaser Synergy what concentration in machine and also what concentration in the recharge. We used 7 percent and 1 1/2 percent in the recharge in our Blaser.
Awesome video, did you have to up the clamping pressure for those cuts or did it remain the same.
I used to roll .25" depth of cut on a conventional lathe at around .015" feed. .024" is crazy.
Did sound like the spindle was slowing down a little well it was in the last cut
Whoa!! Straight beast!!
Awesome ! Thats Some Quality Content you Put Out On That Puma Tyson !👌👌👍
I used to cut tons for 4140, and holy shit that was insane. 😂
Good to see ya buddy. That cut was NUTS....BBOOOOOMM!!!
nice video! you should try SMG 1115 or the Kendametal Spat MD ive been using this insert for years and easy cuts @.480 - .500 per side and at 15in length of cut.
When I look at the insert... I don't get where the cutting edges are...
