$200,000 Damage | EPIC FAIL… Machinist CRASHES TWO MACHINES at the Same Time

How Is This Even Possible? Have You Seen Anything Like This? Not Just The Double CRASH… But The Attitude Of The Machinist Involved… and What Happens at the End? UNBELIEVABLE…

we always always ran a new program in single block for the first cycle with no part & spindle & coolant off to make sure no errors in the program
On the first part to check dimensions we ran in optional stop!! yes this was back in the early 1970's, before all the fancy probes
we were NC & CNC operators, not button pushers!!

Im a machinist for 10 years and im really trying my best, but some days im just not 100 procent spot on. One time i started a new program and The mill was so close to the workpiece and went g00 full speed straight down crashing in the vise. I tryed to react but the machine was way to fast. This happend 2 of 3 Times to me. Most of the time i check everything and doing my best, but im not perfect, IT takes so much focus/energie. Any of you have some tips for me how i van catch these errors.

That is the worst raise I have ever heard.

Its not even the guys fault, his attitude is what is fostered by the American work culture. It doesnt surprise me at all that he managed to get a promotion and a raise. 😂

Crazy. Personally i like proof out stuff 100 percent. Even then dont trust the machine. Where i worked you just paused where you were at and then went to break. The company had to many things happen while on break.

Look its one thing to missread or dont see specific stuff on a drawing and making bad parts but starting a new programm without turning the rapid down and watch it for at least the first time? bro wtf... just because it was run 100 times before doesnt mean somone could change something without you knowing it. and even if its saved for later use..just fking slow run it.

What company is this where you get promoted if you fuck it up big time? I got my CV ready!

W axis coming down and crashing on Mazak V100. Wasn't there for it though but it's the worse I've heard about. I don't know how that's even possible. Got to run the machine myself for quite some time and I can crank the knee on a bridgeport faster. But it's all that weight coming down onto the 5 axis knucklehead spindle that makes it so expensive and probably created an earthquake in the shop.

my boss told me one that theres no such thing as a good machineist that doesnt pay attention

I'm a cnc machinist. Even if I'm in the middle of a run, if I change a tool, I always watch the new tool in for the first time. It's what we were trained to do.

My worst crash was completly my fault I was programming my program and I’m still a student so I ask my boss to come check and he say everything was good and unfortunately I make a mistake I put the wrong G54 code ( I put G56 axes for the G54) and my boss didn’t notice so I go Block after Block and there come the NC Milling for chamfer and the NC make a Z and the chamfer wasn’t enough so I put G56 changes and the NC makes a full speed blast into the pieces I was oh shit dude I go to my boss and I say everything now I’m still in the company and I finish this year my formation 😁😁😁

Whenever I work in CNC I never leave an unproven machine unattended.

If that where my employee he would have been put on probation, and maybe laid off depending on who he is.

I re align cnc machines lol.. I'm learning how to do all the rails and like the felt rail things. Mainly on Doosans but the other day I got to work on these really old cnc machines.. they was in this old ass shop in Ohio , and looked like a dungeon but. It was like time stopped in there and it was still the 70s an 80s lol. They were called mori seiki or something like that. That were easier to work on lol

Big shop syndrome. I do all those jobs myself. The only thing I can blame is the machines are old as fuck and jobs take a long time,, running 32k per program with modern software and old machines. I can’t win many jobs when the company is quoting my full shop time and our competitors have modern software AND machines,

Just 2 days ago a classmate of mine dropped a conventional mill's bed on the concrete, bending the Z-axis wheel crooked. He had no remorse and kept blaming the bed being "too slippery". The same guy also didn't fix down his 3-jaw about a year ago, causing it the fly off the machine at 2k rpm and grazing his face. Instead of being shooked or scared he proclaimed loudly that "this wasn't even the worst that had happened to him". Absolute nutcase

I'm a machinist who has encountered similar situations. In my current shop, I'm caught in a dilemma: if I take the time to review the program, it's considered time-wasting, but if I skip it, I risk jeopardizing the machine's safety. Despite the backlash, I choose to verify the program, which is frustrating, to say the least. I've been with this shop for five years, and I'm leaving for a new shop in just six days. The issue here primarily lies with the management.

You never hit cycle start then walk away. Always dry run the program before running production.

I work on CNC machines for 8 years and even when I go to toilet, I am totaly scared and people are surprised that I am running and have no time for them when I meet someone because I have to return to machine fast or who knows what could happen, but unfortunately, you can't just stay there always, people want something from you, your bosses want something from you, you have to constantly going somewhere, but when you go somewhere and you are running program which is not that tested, just pause it! Always do that and also when you work with wood, it can start burning when you are not there when when you return, it can be too late and I am not kidding, it happened several times and some people really are not that responsible, they put something to machine and then they go watch movies on phone or something, when you are only person on night shift, you can also fall asleep somewhere and I don't mean like I sleep in work, but it just can happen, we are just people, so always pause it when you are leaving.
And letting machine run when you have break....jesus, I have to even shut lights off or our owner will yell to me that it burns electricity. :-D

Those service men who fix your machine are doing magic after some crashes or fire. And when you have only one CNC and whole company is addicted to that one machine, push on your bosses or owner to buy at least second machine, we had just one CNC in the past and THANK GOD that we already had second one when some a bigger accident happened. And it doesn't have to be literally accident, sometimes it just need some maintenance which can't be done on your place and they have to take some part of machine to their workwhop and they will return it maybe 2 weeks later, it happens all the time. Sometimes some little ridiculous part will break and it looks like small problem, but they don't have it on stock and you can wait even 2 months for that, so ALWAYS HAVE AT LEAST 2 MACHINES which are able to do all your work or you are screwed and never let it run when you are leaving for longer time than like 1 minute.

I envy people who can just put material there, select a program and watch, in wood production, it doesn't work like that, operator is always even programmer or programmer needs to be somewhere around because most of parts are atypic, people want some nonsenses from you all the time and you have to be able at least to copy program and edit it. But on other hand, load some long program which I didn't made and didn't test by myself and just watch, that would be stressful for me, I have to do everything by myself or I don't want to touch it, I don't really trust to other people. We had "experts" who were working half of the day with broken tool and didn't even notice that, so at the end, you have to do everything by yourself or it won't be done at all. Or you are explaining to some Ukrainian who can't even understand to you "don't putt this here, it will crash to it" and you go around him and he puted it there once again, it's so frustrating, that's why I don't even want another people because I just deny to train some ukrainians or romanians who don't understand you and they will leave after few weeks, such wasting of time. And don't take me wrong, I am not literally against foreign workers, I know that we need them, but I just can't teach such complicated work when that person can't unerstand me. The worst thing is that everything is totaly different on each machine, so you can crash it because of some habit from other machine which is not compatible with different machine, like to put something on beams next to suckers, which is fine on one machine, but other machine has bigger spindle which will hit that, it's so stresfull to explain all these things to someone new because you know that he will crash it 1 minute after you told him don't do that.

Since we removed afternoon and night shifts (because of no people) and I am always here, we had only few little crashes, mostly something I can fix by myself without calling service, but when we worked on shifts, I arrived to night shift for example and machine was burned or something, it was crazy time. :-D And I am not saying everything wrong happened only to other people, but when it started burning when I had shift, I just killed flames in few seconds and pretty much nothing happend because I WAS THERE next to machine, not on break.

I hear you Bro. I had a Haas tech ram my probe because we had difficulty calibrating. Some macros are not built properly. The probe rammed. The macro overrides the rapid rate, and it was an F’ing calibration. Not always is all I’m saying.

I see thats where im going wrong. So, to get a promotion i just need to crash machines while im on my lunch break. Got it. I knew i was doing it all wrong!!

on man i seen a guy like this at bell helicopter when i was working there

We had an operator that did the same thing. New program, hit go and walked away (again, new program... not a new operator. He knew better and had been trained in the correct procedure). He managed to do something I haven't seen in my 25yrs in manufacturing. Whatever was wrong with the program caused a collision that broke the rails in half off a Studor OD grinder to the point where you could see the concrete substrate base.

Luckily no one was hurt and the doors contained the part, but I have never seen a machine destroyed like that. It was only a handful of years old and was a total loss. There was no repairing it. Sad part was... he damaged 2 more grinders before he left the company. Some people never learn.

worst cnc crash, Doosan Puma with the cervic coupling broken into three pieces when boring bar hit extended part at 100% rapid.

A large billet was turning on the table of a 5 axis mill, the corners were already meant to be milled off in s previous operation. C axis rotated and corners of the billet sheared off while the machine powered through it. We never were able to get rid of all the C axis backlash.

I recently crashed a haas probe body and you knows who fault it was? my no good dirty rotten pig stealin great great grandfather.

These machines are a god send of humans technology id treat them as my own machine

Any new program run it in single block and control the feed!

What an unfortunate shame.....I guess some of these more complex CNC machines need to be recalibrated, maintained, and tuned on a daily, weekly basis. Parts get worn, like spindles, chucks, base plates, and a number of other things not just drill bits and bearings..?

Where's the damn videos? This video sucks.

there because I hate running other people's programs .. especially engineers who don't know anything .. yes but we have simulated,, yes thank you but have you taken machine parameters and setup into account .. then you are about to give up

So I put a bar stop too far out from the back of a cnc turning machine and it sent the guard through the reception window

Got fired from a machine shop so that the bosses little brother could have my job. Within two weeks the little brother crashed the CNC Mill causing over $100,000 in damage. He had changed the offsets like he had seen me do numerous times but obviously did not know what he was doing.

Monarc mill on a fresh setup the forman set the stops as he was setting up for a job 3 axes machine cnc was rather new at that time and these machines cost about 250k each back then we had 3 of them.
The tape was feed into the machine and
The tool loaded dropping down to kiss off the first part the mill kept lowering tords the table into the part it was a very large part. It bent to tool change cage among other things I belive it jacked up the spindle that machine was down a month or so, ive seen a puma cnc lath run into the chuck. Just stupid crap and somone not paying attention. The Forman was a journeyman machinest that specializes in mills. He told me and I was around 18 at that time school taught him a bridgport was the only tool that could make its selfe, I said Bullshit. A lathe can make a lathe, he said how do you make the ways? I said they are round, he thought
Every time he came up with something a lathe couldn't do i had an answer.
A lathe can make a lathe, maybe not the one you used but one that works.
You just have to think outside the box.
Don't belive everything somone tells you.
You can figer something else around the problem.

Price in workmanship is something rare these days.

Hahahahahahahahahahahahahahaha

Your right what you say mate😮

Lemme guess... 🤔 his dad runs company.😅😅

Hey your endmill is glowing!
"I know, shes just warmin' up"
You'd get better tool life if you adjust your feed and speed and put a lil coolant on it.

I am thankful that I program and operate lasers and punches rather than these beasts. The fear of doing 200k damage just doesn't even register.

First run: Eyes on the tool in the spindle. One hand on Fast-travel speed control, Other hand over the kill-switch.
You don't have another machine. As a matter of fact as far as you're concerned the rest of the universe might as well not exist.
If your bodily functions give you trouble, you put the machine on hold at an appropriate step, make certain that the "First run" sign is in front of the controls, take care of the issue, return as fast as possible.

I operate explosives machines (ammo primers), so if you get about 200 primers to ignite....KABOOM! It haunts you for months. You're afraid to push 'start' for a few weeks.

Own your shit. Change of subject, I saw a tool glowing dark red, does it really retain cutting performance at that temperature????

This cluster fudge is further evidence of what I have observed after 25 years in industrial repair, mostly biotech, that management is not necessarily looking out for the business but playing political games for themselves. Do business owners realize this?

Ahhh, the ol pretend everything is not so bad and maybe the boss won't notice. 🥴

This dude his mouth all ways lound

I'm new to cnc and refuse to let my machine run while on break. I've been in the industry long enough to know better. I know it's common practice but it isn't for this guy.
