What not to do with your CNC.

[ftlqed]

Half is you need lithum halfnium, Like the guy sold a ninja sword that is actually halfnium lithum, but secondarily, its basically a carbon disc, make some halfnium lithium. Then fuck it up.

[brvkloshar]

-cooling

-NO is good

[HoracioFH01]

que animal cualquier programador sabe que se debe revisar el programas antes de correrlo, pendejo,

[2tktsylimon]

can sombody tellme what kind and where to get those bit

[promethiusrising]

If magnesium caught fire it would have ended differently.

[wordreet]

Why is everyone talking about magnesium? There's no info about the material. Seems to me this was set up to demonstrate what happens during a machining error. The tiny bit of flame is from the cutter burning out due to excessive spindle speed without coolant. It could easily happen with a carbide slot drill going into a steel billet.

[dobypaw]

Coolant might have help the situation... HA HA HA!!!!

[r1ot1ng247]

could it be that the feed rate was too slow with the depth of cut being too deep causing too much heat and therefore igniting the magnesium

[Dragonmk188]

WOW indeed!

[Paxmax]

wow!

[JackHighlander]

a guy at my old job walked away and left the cnc running. in the meanwhile, it ran out of coolant. when he came back, the mill was welded to the piece he was machining from the heat.

[pylodj7]

usa mastercam x para programar

[iroczluvr]

You need some coolant bub.

[SwissArmyBumpkin]

soooo, why did you just happen to be filming it?

[abuelofilico]

como eres pendejooo

[Mecanico78]

That was cool

- Butt-Head hahahahaa!

[wii41290]

what material is that?

[troglodyte3344]

don't put your penis on it either. that really fucks it up

[totalrandomcrap]

@troglodyte3344 Yeah, my penis would fuck up that lathe pretty bad!

[southernrock20]

that was actually one of the coolest f' ups ive ever seen

[Just1Spark]

When I crash, its never that kewl lookin. :*(

[Milby20289394bc]

why did it do that? was it magnesium or something?

[jerbearthegr8one]

I started trying to learn g-code programming on a BROTHER machine before and sent a drill bit about 4 inches too deep within less than a sec. lol its amazing how fast and strong and precise these things can be.

[blackcat852]

i work with cncs and i have to say this video made me cringe... not the actual cock up, but just waiting for something to go wrong

[leighhills1]

hahahahaaa I LOL-ed

[Darwinisti]

Not even bad

[erd39030]

Is this a demostration of friction stir welding?

[SpecialEdAllstar]

i just just had this happen at work. new program and I drew the short straw to prove it out. fun stuff.

[daytonamon40]

@wolfie83 I haven't crashed anything yet! but i'm sure it will happen someday when I get older... been machining almost 8 years cnc and manual.

[marcosjsmenezes1]

good job ! donkey

[ijzerable]

wil er iemand een vuurtje?

[lepompier132]

From I see, the spinddle is going in revers with that flame. Before filming, check your programs that way you won't look stupid and you won't be in the FAIL section.

[joshdrobny]

@lepompier132 you can tell that from a flame? i dont believe that lol

[lepompier132]

I've seen harder crash, How about a hybrid cnc lathe with one of the jaw that decide to break free of the chuck. The 5KG 304 SS blank disk flew and this a lot of damages in that lathe.

[lessirkilion]

that wasn't a crash lol that was just a high feed rate or rapid set to 25%, i've indexed into a chuck before and had a jaw with high swing hit a tool holder on the opposite side of the turret while workpiece was spinning at 2500 rpm, which sent the part flying and tore the jaws right off the chuck

[nesikachad]

Oops.

[Gunner3210]

oooh this machine makes fire?

[Gauntletbloggs]

Lol since when are slots made using drills you muppets? last i heard Slot mills or Endmills dids that job >.< a drill would've snapped.

[BKMillMan]

Single block is your friend.

[pantherxx010]

There goes the drill bit

[dougie730]

@pantherxx010 "endmill!!"

[pantherxx010]

@dougie730 errr yeah whatever. heh heh

[infinitycrops]

abort! abort! abort!

[Vanc3y84]

didn't the moron filming this see that his first ghost pass hit NOTHING, and that the second pass was A LITTLE deep.

[floydy22]

@Vanc3y84 I agree, this looked like a planned demonstration to me ??

[SgtRum]

Fire Fire!!, was the NC code generated from CAM software?

[barbarotico]

I discovered that the pee is exelent as refrigerant.

[EJRubio002]

jajaja no mames. a hecharle lubricante men!!!

[rick371]

the tool magazine drops with the spindle....thats first time ive ever seen that...

[towertek]

Ive done that!

[ROCKNTV1]

cool light show

[MISFIT585]

ahhh good times!

[arnold02000]

I had a crash one time on a manual vertical. One part caught on a large cutter, tore it out of it's setup and crushed my hand against another part of the machine. Almost cut my one index finger into two pieces. The other part flew out of the mill and lodged in the wall. The crash club has an expensive price tag.

[agwhitaker]

You haven't crashed ?

You haven't machined.

But what's with the drill chuck at the right side of the job?

Is that being used as a center !?!

[StickerMedia]

That's fucked..

[tlsumner]

Oh LoL !

[SteamingObe]

Weeeew!!! Running a little hot?

[alderaforall]

coolant wouldn't have helped, there was a programming erorr. should have set his z zero a couple inches above the part first and run the program to see if things were looking right. Hopefully he learned something from this crash. These things happen to everyone that runs a cnc, just part of the game.

[bradenn]

@alderaforall I disagree. I'm apprenticing to be a machinist and I'm told to spend as much time as necessary to prevent things like this from happening. No matter what it doesn't cost as much to spend the time required to make a part perfect the first time.

[alderaforall]

@bradenn it's only a matter of time before you become a member of the crash team. Like I said, anyone that programs, sets up, and operates a cnc machine is going to crash one at some point. Disagree all you want just know when your day finally arrives, you aren't alone. Figure out what lead up to the crash and learn from the mistake. Keep your head in the game and good luck with your apprenticeship

[bradenn]

@alderaforall Please don't take my comments as arguing with you or anything like that, because I'm all for learning, especially from someone as experienced as yourself. I have been working in a machine shop for 18 months now and my apprenticeship starts in a few weeks I am super excited. I expect that I'm going to crash a few machines but (in your opinion) ... do you think there is a "limit" as to how many times an average machinist crashes before they attain "the feel" or "the eye" ?

[alderaforall]

@bradenn the 'limit' would be when you are walked out of the shop. Learn your G and M codes, learn proper placement of tool calls, and watch/listen while the tool is in the cut. Listen to guys that have been in the shop for awhile, they are a goldmine of experince. Rigidity is the ultimate goal of each setup and your finished part is only as good as your setup. Again, good luck. I wish I could have gotten into an apprenticeship program.

[baccus61]

@bradenn I actually disagree with this as sooner or later complacency will set in and you will think you are doing the same job you have done a hundreds times and you will forget to check something trivial that leads to a tool breakage or worse a job piece stuff up.

Even the best machinists will make a mistake sooner or later. It's human nature. That's why there are simulators out there. We wouldn't need them if we were all perfect. :-)

I wish you well in your apprenticeship. Learn well.:-)

[Shazee083]

what not to do with your cnc

or what do with cnc

[DixonPhano]

Dry run !

[tony30able]

All they needed to do was run some coolant on it!

[R75Sidecar]

It just goes to show that you can have the best machine in the world but you need good setters to run them. What pillock used a drill chuck as an end support centre?

[madinventor13]

SCRAAAAPP!!!! better go saw of some more stock. 

[tony30able]

@madinventor13 lol! yep, its scrap!

[TheBullShitCompany]

looks realy nice

[onefugowie]

music to my ears...i sell tools........

[william4art]

My eyes immediately said OMG WTF! Your going to cut a 5/8 or 3/4 channel (what depth ? ) in a piece of round stock secured with only a lathe chuck and a center? OMGOSH Its not a vise! This piece of steel should have been clamped to a large angle plate at both ends ON A DIFFERENT KIND OF MILL. After cutting the channel in it with it properly secured,you would put it in this machine for cutting the outside diameter dimensions and cutting the ends in to length.DONE! This video should be taken down

[SupermaxCNC]

@william4art

Its not steel, some sort of composite. Hence the dust and flame.

[william4art]

whats up with downfeeding in the middle of the cut,, no amount of coolant would help.. the cutter would still break...just no fire... lol......WOW!!! whos posting these bad vids

[P0RNEX]

Yes man i make Fire Day for Day at Work with my CNC Machine ;)

[dtiydr]

At 0:15 and maybe max 10 sec forward and absolutely 0:27 i would have stopped the program for sure.

[wolfie83]

lol i have crashed harder, gotta love fucking up...everyone does it, anyone that says they dont is a liar.

[Chooky308]

@wolfie83 but your a fool if you say that you do lol

[wolfie83]

@Chooky308 A fool doesn't admit a mistake, my boss would write me up for trying to conceal a crash...they would prefer we're upfront and fix it quickly.

[venom5610]

@wolfie83 iv done it quite a few times. always scary.

[Forbidenangel0]

hahaha lol face palm fail

[7ZakkBlatt]

lol idiot^^

[SuperStefano1995]

coooool

[davearmie]

OK, Now let's try it with the spindle in FORWARD!

[DekuTreeOfKokiri]

Kill it with fire!

[HeartOfDota]

wow xD

[Nighthawke75]

He should have known something funny was going on 20 seconds into the program run.

[artgoat]

Hmm.  Was that Z=+0.1250 or Z=-0.1250?

[nicowjensen]

L2 metric system!

[kathump2]

I bet ya ass puckered up like ya ate 100 pounds of prunes!

[kathump2]

Bet ya ass puckered up like ya just ate a 100 pound bag of prunes!

[vpitool]

I don't think  you had the RPM high enough. Why don't you really wind her up?? :)

[kiko21pt]

@vpitool it was the Z axis, I think!

[onefugowie]

you made me laugh my ass off...i was looking on the net for CNC crashing..man it hurts to look at this stuff...

[davearmie]

@onefugowie

Oh, come on. You're just like the rest of us.  Just looking fore something as impressive as what happened on my machine earlier last week.

[paul8246]

all you are wrong it should coolet with oil and water switch on and it won't happen like this

[8Zeitgeist]

why dont you pay attention!

[jdslick1234]

do that with some titanium the fireworks show is awesome

[BlaueElise89]

Oha, ne ganz heiße Sache! Respekt! :-)

[706jim]

Smokin!

[plord28]

LOL BIG OOOPS!

[bushputz]

Looks like someone might be looking for a new set up man...

[bunter76]

cutter spinning the wrong way methinks...

[deflumte]

That's not a drill bit, that's a laser cnc!

[sascha1989sg]

hey the first CNC that works with fire lol

[MastaElTom]

haha lool

[HOJNIA88]

hehe :)

[Eltern10]

cooling!!!!!!!!!!!!

[BigBobD89]

i don't know with what drill bits u work dodoslovensko, but in germany for such a machine the bits are a little bit more expensive

[WMaxx91]

This tool is burned up^^

[ctothej586]

for one its not a drill, and two you can only use oil as coolant on magnesium.

If he were milling magnesium and it started to combust, it would have burned up the whole thimg viciously!

Unless he had some dry chemical to put out a class D fire.

[dodoslovensko]

u have 40$ for one new drill bit , but u dont have 5$ for a 10 gallons of cooling emulsion?

[schenkel123]

append one or two zeros to your 40$...

[Shazee083]

@dodoslovensko isn't coolent mad for when using on magnesium cause its so bright and very week structure and week stress point 

[baccus61]

@Shazee083 Coolant does three jobs. It keeps the job and cutter cool and lubricates the cutter. Modern testing shows that flood cooling actually causes micro fractures in the carbide tooling and reduces the tool life. This is why you will see a lot of misting coolant on some cnc equipment. And it flushes out cutting chips from long/deep cuts like drilling or deep mold parts.

It would probably stop a fire with magnesium and titanium as well if you got it too hot.

[soundspark]

@baccus61 Coolant plus magnesium could mean big fire.

[ExtremeDeathman]

@baccus61

Magnesium and Titanium fires can't be fought with coolant nor water. You need antioxidant foam liquid to stop them...

[baccus61]

@ExtremeDeathman

Yep. Totally agree. That's why you try and stop it from happening BEFORE it gets hot enough to combust.

It's probably the last thing I would want to happen. I can put up with a broken cutter and stuffed up material but I like my machinery with all the paint on and no warping. :-)

[havefaith96]

@dodoslovensko coolant is actually rather expensive. a 5 gallon bucket of decent coolant concentrate can easily cost 200$. That wasn't the issue here anyway.

[baccus61]

@dodoslovensko I would like some of your coolant for $5 a gallon. Over here it's around $60 for 4 liters.

[artgoat]

@baccus61 Seriously! Even WD-40 is a lot more than $5 a gallon.

[BarneyKraft]

@dodoslovensko First of all, that's an endmill not a drill, and second, magnesium is most often machined dry...

[domgod90]

@BarneyKraft are you sure about that, where I worked magnesium is ALWAYS machined with coolant. If you run out of coolant it can be a fire hazard.

[ExtantFrodo]

ouch, I can smell it from here.

[KoalaLumpUhr]

I think this is a can o hairspray or so...?

[JTMarlin8]

What happened? Spindle reversed?

[MetallicAsian]

Wrong program

[stevezur]

What kind of material are you cutting?

[livingkenny]

magnesium burns better and don´t stop if the machine is turned off^^
