- Machining a component on our DMG Mori NLX2500SY in our hydraulic cylinder component division.
Edit
The machining sequence on this part has been done in this way because of deflection and vibration in the part. - Věda a technologie
That drilling op was pretty bananas.
Yeah, what could have been the feed rate???
Looked hot to me too lol
@@gregorteply9034 bit late reply but with those drills up to 0,5mm per rev. ~0,02" On that cut defo not slower than 0,25.
Excellent piece of turning and well filmed mate thanks for sharing 👍
I'm still learning at school on cnc machinist but this is incredible. I love watching complete programs like this. Nice work!
I’m an experienced CNC machinist and trust me, whatever you do, don’t machine like this! The program might look good but the parts will be dog shit when they go through inspection. Maybe if you’re working with +/-0.5mm tolerances but not if you’re making high spec components
Glad you enjoy it!
@@bethfaulkner4907 obviously you're not he has a great machine he is producing a great finish what else would you want? that is the beauty of having a DMG
@@bethfaulkner4907 becaaaaause?
@@bethfaulkner4907 Idk about you but I was able to hold under 0.1mm on all critical dimensions of all production parts on a M1, by spending huge effort in correcting the runout of all tools upon installation and having done a reversal method calibration of the tool presetter (it is repeatable to under 3μm but it measures a little oversize out of the box and doesn't account for deflection either), and fine tuned my program after the first run.
I was running only high quality and high end tools, to their peak performance limits, and just knew when to toss them, as I was full slotting on steel at 1.25xD, at up to 1.7meters a minute feed rate with an 8mm end mill, or side milling aluminum at up to 7.2meteres/min at 12k rpm with a 12mm end mill, or side slotting others at 15 freaking meters a minute with (and never skipping a beat, never missing a corner).
The most impressive for me was drilling 9mm holes through 30mm of steel in under a second (a smidge over 0.78 seconds at 2.25meters a minute) with a solid carbide drill, and lasting for more than 3000 in size, on position, and pretty damn smooth and shiny holes (the end of life condition of this drill was wrapping 2 thick chips around it at 6k rpm and filling the whole factory with a mist of coolant, due to under 0.2mm of wear on it's split point)!
As an experienced CNC machinist myself, I can say that It is way more repeatable than putting diapers on your machine, and while you will probably never be able to run prototypes and one offs like that, it's the only way to run for mass production!
nice job
Thanks for taking the time to make the video and share it
Brutal cuts, amazing speed.
If you want to see brutal speed check my channel
such a cool machine, all modes work well, it seems to me as if it was me working
😮😮😮😮😮😮😳😳😳😳😳🤯🤯🤯🤯🤯 a long time ago I was not impressed by something like this, it really is impressive
Holy crud I have never seen a face mill like that in a lathe's live tooling. NLX machines are crazy.
The NLX has very impressive milling capabilities
Nice programming and the right cutting data! Presumably it is a high volume to detail because deburring did not occur :)
Well done!
Thank you. Yes, almost all batches in production are large quantity so most machining time is used to remove metal instead of deburring
@@PBMachineTechLtd I don't know why you wouldn't deburr in the machine, it's better and more reliable than getting an operator spending hours at it.
@@gredangeo true that part would have been almost completly deburred in about 20-30 secs maximum in that time the operator can do something better than deburring
Pas de lubrifiant ?
Percer sans dégager une seul fois ?
Absolutely beautiful piece of programming. If this was filmed all at once, that piece must have been soooo hot.
It was all done in 1 hit. It was warm but not too hot.
impressive overhang!!
Some rapid movements are done with the tool engaged... tells you how much these tools can actually take.
Major pucker event when the sub comes flying in 👍
Hello do know why it’s head 2 sv motor overhead [XS] please help what I need to do to fix this problem ??
A hell of a lot of shavings. Surely in the end there will be a fierce overpricing. But the machine is, of course, awesome.
Hello
Can i know the price of this cnc
Damn, you guys are not messing around here. Nicely done, bit rough on that grooving tool though.
Its a little rough without coolant. With coolant its running slightly hard than in this video
how this can stop so fast ? crazy stuff
Excellent tooling
I've never dealt with live tooling but I have to ask but not why not drill the hole after the endmill instead of before? This would likely decrease cycle time and improve insert longevity since there will be less material to cut through. I'm assuming is has to do something with how thin the material will be after the endmill? Looking forward to your reply.
Correct, its down to how much material is left after milling. The length, overhang and finish thickness all have an effect and caused the part to deflect when drilling, this creates a list of issues. Ideally all milling would be done and then drilling, but it isnt possible in this case
Great work! That was fun to watch.
Hehe Grimsmo 🌸🌸 , did not think that I would find a expert in the comments
Glad you enjoyed it!
This is definitely the owners son programming 😂
😂 I figured too
???? huh?
i dont understood nothing
@@calcio437 feed-rate is damaging tools
@@johny_doe no water damaging tools
I couldn't quite tell from the camera angle, but it looked like there might have been more than one cutting tool while the OD was being turned.
Just 1 tool being used to cut the OD in this process. 2 tools mounted on the same position with different Y offsets so what you are seeing is probably the other tool.
4:40 next starts to play CCR-Fortunate Son
Pretty sure after 20pcs change inserts. Does this machine work with dynamic rough?
Coolant was left off sorely for recording, no inserts were harmed in making these parts. Roughing path was generated by CELOS
@@PBMachineTechLtd haha, "no inserts were harmed in the making of these parts"
How are you not getting any vibrations??
Operations are in a certain order to reduce as much as possible
A mori with gang tooling?
what does the SY stand for
Subspindle, Y axis
this trade is pretty kool ngl
If this is still an active part. Everything looks great but there is a missed opportunity for part process security. Use the ball nose endmill that you do the rad with to deburr the part. This will add cycle time but the part will need considerably less hand work to be shippable or weldable.
This part is fully deburred in machine now
That fucking drill op was insane dude
Its pretty cool alright
Where is the coolent??
Coolant on = nothing to see
Hello friends, I'm very happy that we have the same job, friends.
Gut programmiert das Werkstück
Pleasure
Feed on the OD groove tool's first few cuts looked way too aggressive
To me it looks fine. If you have a stable machine and the rigth inserts its no problem. And did you see any sparks? Or other things that did not look okey?
Try machining like that on a Doosan. No chance. DMG MORI machines are the absolute best.
They are hard to beat but my Haas mini is close 🤣
Lot of unnessesary waste. I'd use smaller diameter raw-part
Keep that conveyor off during most cycles. It's a good way to get chips down in the coolant tank
and mainly it lets the chips drain of coolant first you lose a lot of coolant if you leave conveyer running too often
@@kransurfing This. I would program the conveyor to run only for the last detail of a 5 minute program so it would let enough chips pile and then carry them up to drain. This cut down our coolant interventions to a quarter and we almost got rid of carry out, since the tank would hold an oil content of within our desired range for months, while we were just topping up with deionized water to compensate for evaporation, about every 4-6 shifts of high volume production
Great example to show people that "the heat is in the chips"
I think this is good, just some weird series of operations going on at points. Not much adaptive machining going on either, more brute force machining but hey, I guess we all have our ways
Epic.
May be drilling operations are better after milling operation and in this component too much stock removed for this component. 5 mm dia meter machining allowenc is sufficient for cnc machine and also tip life also became longer
The stock is stiffer before milling to allow for higher drilling forces, don't you think?
Correct. Stock deflects if drilling is carried out after milling
Great job. With CAD/CAM/CAE you can do anything! :)
No CAM here. Just manual G code programming
@@PBMachineTechLtd I do manual programming most of the time actually but on 3-axis mill.
Batman hears a G96 in the code. Let those chips fly!
haha and G95 ;-)
nice

This machine is CNC or HMC
Please clarify the doubt expert's
This machine have a spindle axis so I assumed this this machine Horizontal maching center
This is s CNC Lathe, not machine centre
@@aravinthkumar6649 Its a lathe with dual spindles and a turret with live tools.
If you want to do production run with those parts I suggest to start with smaller stock. I like the agresivness of operations the machine was used but not abused
I guess that's for demo purposes, I was baffled by the confident depth of cut and no predrilling with a smaller diameter. Great machine, confident machinist/company :)
😂 Programer must be drinking too much..
I missed cnc
No offense but how on earth can any of you guys determine if this it good or bad feeds or speeds. You dont know what material this is, what kind of inserts are used or what the priority of this job is. Or am i missing something?
And the thing about not using coolant. Any machinist that has not lived under a rock for the last 10 years know that dry machining is more and more common these days. Cutting fluids main job is to get burrs out of the way, provide cooling comes second. Buying and disposing of coolant is a big cost for companies and their staff/enviroment. A lot of people develop allergies and stuff from working with these chemicals year after year. Modern inserts can take the heat and actually lasts longer with a stable temperature, especially during the milling operations. I have seen so many shops running their machines and tools on half speed believing that they are saving money cause the inserts last longer when the real costs is salaries, machines, rent etc. At least here in Sweden the average cost of an quality insert is 10-12$ which is a small fee relative to other production costs.
First bit of common sense I've seen in a CZcams comment.
Or microfracturing the coating by hogging with coolant on. Get it nice and hot during the cut and instantly shock it with coolant
Daniel, I totally agree with your first paragraph. The only thing I was wanting to change was all the extra axis moves during the tool changes and when the tool would retract so the spindle could rotate 180 or do another operation. So jerky and annoying.
It looks more satisfactory than meeting with girlfriend.
Im waiting for mill chamfering tools but 😅 anyway good works sir
No more room in the turret for chamfering. Output always more important than deburring
I love cnc
عمل جيد
Hole drilling can be done after milling to reduce CPC
I think it is being drilled this way because before milling you have a beafy chunk of metal so your part won't bend while drilling and boring.
Correct. Drilling was done like this because the part was deflecting if drilled after milling.
when will you give me a tool as a gift
With
G4 X100 (100 sec pause)
You can stop the machine a little
It seems you wanted to waste a lot of time ^^
Wow that cnc machine must be really expensive, more than 20 dollars
My guess is more than 30 dollars.
Try 1million usd
Has to be at least $40 😆
Многофункциональный станочек💪👍
why is so much material wasted, u must scrap & process your own cutouts
没想到金属加工的视频可以一直看
Mntaps
rip diamonds
uhh da sind aber böse Rattermarken auf den Planflächen
Im Licht ist es schlimmer. Sehr kleines Geschwätz, kein Problem in diesem Bereich
@@PBMachineTechLtd Aw that reply cracked me up, chatter does indeed translate to Geschwätz but machining chatter in German is called "Rattern" (to rattle, Rattermarken = rattle marks). Geschwätz is basically verbal chatter or gossip :) Anyway, great video, confident depth of cut and boring, you got me cringing for a second there!
I am cnc/vmc m/c operator
Feel sorry for the guy that has to deburr these and more if set to do night runs.
Fuckin mint haha
20% part from raw material.
So wasteful.
Nah I'm sure the strength requirements demand machining from solid stock.
Кто писал пролраму седой походу!
ого на таком вылете при обработки фрезы и деталь не отгибает) у меня бы уже вырвало все на свете )
seems like it was programmed by a beginner... keep practicing
Man I agree, that grooving tool looked really aggressive and the start point in x was actually removing material when it moved in z. No deburr on the through hole either.
Why because he did all that boring the removed 75% of it? So what.
@@matthewcncsutton5283 why drill the hole and then try to mill through an interrupted cut? That’s hard on inserts and isn’t good for part stability. It would have been much more rigid to mill that way without the big hole in it
@@patrickmartinez3217 I realized that hints why I mentioned it.
@@patrickmartinez3217 and then drill in a thin part that bends? sometimes i think people dont use theyre Brain and only want to rant about other Machinists. If you dont know the costumer or even have seen the Drawing you should not say its wrong. And if this is a small production run or even like a one off part then nobody cares about that.

Ok? Guess what? No one ever said "Gee I should check out this random company spamming bullshit"
Way too aggressive and no coolant
we would see nothing with coolant, its probably only for the video
Thats how u make money
@Yeah Right running few parts with no coolant is fine
Of course tools will hold longer with coolant depending on material
But if i ever do something on conventional machines i usually dont use coolant
As long as the chips fly away like popcorn its gona be ok
@@LordOfChaos.x i run every Tool in my mill dry in stell. only use coolant for drills to get chips out. And even the Tools lives longer and can run more agressive if running dry. only thing coolant will help is by holding the part cool if the cut isnt perfect to get the heat in the chip
@@Der_Drache ever heard of lubrification?
Sure if u run parts at super low speeds they are gona hold
A tool will always hold longer with coolant than without
There is ways gona be friction between the cutter and the part surfaces
Unless we talk about turning
There depending on material or cutter coolant may be better
Have u ever seen Titans of CNC running parts without coolant unless its for show purpose only?
No
Wrong strategy of the machining, it could be machined quicker
Would like your input on a different way to machine this part
....This is just for fun stunt. dont try this at home....
You're correct. This is should not be tried at home, only in a machine shop capable of running like this 24hours a day
Need to rethink your coding , not the most efficient way to machine that
Everyday is a learning day, would love to hear your thoughts on how it should be done
Get some coolant on it FFS
Bad work
No lol.
