why we cant see the first positioning results?? :D

looks good....I need 100,000 of them. lol🙂

on a milling cutter, T3M6 is for moving the tool to the spindle T6 is only for calling up the next tool ,, the tool moves forward so it is ready to go into the spindle .. T3 and T6 are swapped around the next tool could be T16 Magazine the table the hold keep an eye on each tool and where it sits in the tool chain

Hello! can you help me with some images of the parameters from the tool sheds?

Use single block for showing programs.

14:35 started the program without reading the tool and offset, that could’ve been bad!! 😂

Thank you for this video i have a hardinge cobra 65 lathe with fanuc 21-t controller and haveing trouble with homing I think I lust all the pramaders 😢

Exellent Explaination thanks so much , your machine is cool

you still use A.D. how peculiar.

scary :(

Danger is involved in every living life,eating can be dangerous,for example you can choke on your food,this just goes to say there is absolutely no such thing as anything at that's not dangerous,everything we do is or can be dangerous in some way shape or form,it doesn't have to be just at work.

I recommend that all machinists watch the uncensored russian lathe accident video. It absolutely motivates you towards safe practices. great essay!

Henry Maudslay was the inventer of the first modern centre lathe, capable of cutting screws to tolerance of several thousandth of an inch on a production machine, not a special hand built one off, his student Sir Joseph Whitworth would standardise thread pitch use and revolutionise rifle accuracy with his Whitworth rifle used by the confederates during the American civil war, he also designed more machine tools than most people have seen or used, the shaper machines of today still use his design.

Yeah, puffer jacket dude. I think I was 16 when I saw that on a machining forum. Some chucklehead posted that thinking it was funny because he knew kids were going to see it.

I have fitted an e-stop switch on the headstock and at the tail stock. I can stand and stay at the right side of the spinning work. When I was training, the work piece started to chatter on the lathe. I turned off the power as as the chuck came to a stop, it fell onto the bed. The previous trainee had not tightened the chuck and I hadn't checked the machine properly.

Aaaaaargh. If you're going to start talking about technical matters, particularly with regards to electric motors, try and get at least some of it right. The person who wrote the utter bollocks in chapter 3 wants to be put in the naughty corner. - When you run a machine in low gear, you do not increase its power. Power is a function of rpm multiplied by torque - when you reduce the rpm through gearing, you increase the torque - the power remains the same (modulo losses in the gearchain). - The 3 phase (and even single-phase) induction motors used in "normal" sized machines (over 3/4 hp and under about 600hp) run at a speed determined by the line frequency, and not voltage. Speed variation is thus done by varying the frequency and not the voltage, the variac you show is useless on all but the most piss-ant little machines. There are exceptions to the use of induction motors, of course, but the use of large DC servos is generally restricted to bloody great CNC machines, and the speed variation circuitry on those is very complex. - For a typical induction motor, the power is not determined by the voltage, which is constant for a given motor ad line supply, but rather the current flowing through the motor. A 1kW motor powered at 400v will nominally draw 2.5A. A 10kW motor powered at 400v will draw 25A. Whilst in theory it would be possible to reduce motor power by reducing the voltage input, this does not typically happen as it's bloody complex to do. Reducing the frequency to reduce the motor speed does not reduce the voltage. - Teslas and (modern) cordless drills mostly do not contain a "variable voltage control". They are driven by what are effectively 3 phase induction motors, and speed is controlled, once again, by varying frequency. Goog god almighty.

I greatly appreciate your production Sir. As a retired Lt. Fire/Medic & ED-RN, I've dealt with numerous industrial incidents, many of which could have been avoided. In my retirement I've acquired 3 lathes, largest being 12x36 manual, 1 CNC mill ~1000Kg with a powerhead for "lathe" work. I've learned much from the mistakes of others, but I could not begin to cover all that info here. Best advice I ever got was from my Father; when he was teaching me to operate power tools, he said son, that tool does not care how loud you scream. I still have all my parts, and I'm always trying to learn. Thank you very much for your information.

Thanks for producing this content. Saftey in the industrial world is nothing to fuck around with.

Muy bonita introducción de máquinas y herramientas 👍🌹🙏

Thank you for reminding us the danger of death only a few inches away from us all day. How many times have I sanded or polished a part until not even half an inch away from the chuck. When you work a lathe everyday for years, you forget the danger of it, it becomes common. I remember my first months working on a CNC lathe, I was scared of everything. I was so nervous pushing the green button after writing my program. My old teacher warned me when I was at school: fear the day you are not nervous around heavy machinery anymore, because this is when accidents start to happen

A very good video thanks. I only have a home shop with a 36” lathe but I’m still cautious with it. I don’t like filing on it because it means one arm has to reach over the spinning chuck.

Great video. Many people forget how powerful these machines really are. In the early 70's, I was introduced to machines like these at a very young age. I was taught that it isn't a playground. It was dangerous, but I understood that quickly. As I've aged and remained in the industry, I've seen what can happen. I've pulled people from machines that tore limbs off people without slowing down. It's no joke. Stay safe out there. It's a brutal world but without it, we will never advance as a species. Cheers. EDIT - there is a horrific video out there of this happening (@12:10). I wont provide the link but it made me very sick to watch it. There was nothing left of him. (that it @25:00) Just be careful...

Lathe is described in Homers Eliad. So it's very very old

Excellent video

Indeed, we need to think before doing anything and the classic No 1 is starting the lathe in motion with the key still in the chuck!

You can, and people both have and still do, in industry and in the hobby shop make things that are square, rectangular and so on in the lathe, including angle plates, cubes, cubes withing cubes and so on, and that is without a milling slide attached to the tool post.

I forgot to include this piece of advice in the video. But after a while, getting used to running lathes, you develop a 'force field' around your body, that you never let get near the chuck or work piece. Full article is available on our website! www.AcsisSystems.com with a bunch more footnotes and first-person point of view style extras. It's a work in progress Note from author: The good news is, after a couple of years as an appretice, you will develop a sort of 6th sense, or force field bubble around your body and you will become more comfortable about knowing where your abdomen and arms are at in relation to the lathe chuck or workpiece. This is very handy specifically for when you are punching information into the DRO which is usually mounted near the chuck. I catch myself all the time going to reach for the DRO or perhaps something in the back of lathe chip pan and being like, nope, 6th sense activated. Then find a safer way by powering down the machine or walking around the entire thing if you must keep the part running. Never lean over the spinning workpiece to grab something, even if your shirt is tucked in, unless you want to be turned into a raspberry slushie.

While machining a large part in a lathe, I was working crossword puzzles to keep from wandering off. The plant manager walked in and chewed me out for reading on the job. He claimed I could clean up around the running machine. I filed for retirement that day.

An excellent video! However, why blur the pictures? Why not state 'This could have been YOU!' or 'Would YOU like to have such an accident?' Sadly, such complacency is common, the old 'well it can't happen to ME.' Oh yes it can' and very quickly too!

Great info, thanks

Sobering.

Yeah, I have a relatively massive lathe, and a few other smaller ones... I treat every machine with respect... If a machine can work metal like its butter, you dont even want to imagine what it can do to your body if it catches you... A large industrial lathe, even a short bed one, really doesnt matter what the dimensions of the machine are, if its a strong industrial machine, it can tear you to shreds like a woodchipper or a meat-grinder... You all can theoretically conjure an impression of the power required to cut continuously say a 4mm(cca 1/8th inch) chip... You can try scraping a piece of steel with a scraper, and you can maybe dig in a fraction of a millimeter with all your power... A large lathe can remove kilograms of steel in minutes pretty much... When you hear that a car has say 250nm of torque or 400, its a decent daily driver, and you know that it can shift its 1ton mass uphill like its nothing... A large machine with 5 or 10 horsepower, with a massive gearbox likely outclasses that like a Bugatti does the VW beetle from back in the day... Just a handheld angle grinder can rip itself out of your hands like you are a child, and that is a toy when compared to a lathe of almost any size... If you have a passion for machines, you watch This Old Tony or others, and you decide to get some machines, never underestimate the immense capacity they have to obliterate you like a landmine... Machines are amazing, beautiful and magnificent pieces of art practically, but just like a car, they are pieces of art that can turn you into chunky paste... Get an apron, have it custom touched up by a tailor to fit you like a latex gimp suit if you can... You dont want to get caught by a machine capable of working metal... Some baby lathes with toothless belt drives can be relatively safe and you can stall them by hand, at least cause the belt to slip, but if there is a chuck on the lathe and a piece of work, that is a relatively large mass that you have to force to a halt, and just a few kilograms(say 6 pounds) of rotating mass at say 1200rpm will be enough to mangle you, not outright obliterate, but it can take your arm off or smash your skull into the bedways if your hair gets caught... The head smash would likely be instant death, the arm could turn into death, but you get the point... While some baby lathes may be under-powered and anemic when compared to larger machines, they are never to be treated without utmost care and respect... The same goes for any other metal working machine, be it a larger pedestal grinder, a drill, a mill or any other configuration of aforementioned machinery... Please, dont ever take risks or engage in stupid setups... If you have the slightest hint of uncertainty regarding safety of any operation, think about it, reconsider the steps, find a solution that at least feels completely safe... And i know its hard, but try finding someone with machine experience, find time and offer to ``apprentice`` under them for some time, just come, hand them the tools they ask for, bring them coffee or whatever they like and learn from them, dont annoy them, but try to get them to teach you... It will only cost you time, and the returns could not only save your life, but you will also see things that could take you years on your own to figure out how to do... And you will make a friend after a few days if you arent an asshole and if the other person isnt an asshole - avoid assholes... Machinists are grumpy, but there is a difference between grumpy and an asshole... TL;DR - just watch the video...

Many thanks for this report ACSIS. A good reminder of the gruesome consequences of COMPLACENCY! Yes, we must not forget the machine is made to turn, spin, cut - whatever - and keep on going. And going! Does not care about the human operator - even 1 HP can make a mess out of you! BE CAREFUL folks, do not be complacent, please!!!

Egyptians floated the blocks into place with the use of a causeway and sealed locks, checkout pyramidsreallybuilt for the video.

Why doesn't every manual lathe have a deadman's pedal connected to the brake?

My job hired me and my co-worker without training despite hydraulic equipment and other dangerous equipment being present. (Its my 1st job and i never have been in any similar environment, even at my stem school) We had to learn on the spot from co-workers (or getting injured or near death lmao). Despite many warnings and safety protocols, the company lets shit get by. Until they freak out for steel toe boots not being used or if the owner is around (who seems to care more about our personal well being than my supervisor who treat us like robots). I dont think ill last more than another 2 months here but my respects to machines, electricity, and people who work across dangerous equipment

Wow, what a wealth of information on this rather niche subject. I always found it morbidly intriguing. Love the fact that you include excerpts from obscure literature. Thanks.

Look up "russian lathe accident". Extreme gore, NSFW.

wouldn't want things to get all blurry...

how do you outfit a lathe with a light guard? don't think whoever thought that was a reasonable idea has ever used a lathe...

Early on, I did electrical work in a sawmill, which included working on a LOT of "rotating" equipment... Even unpowered, one could simply get a machine rotating, to inspect it, or clean it, and the sheer rotating mass could drag a hand into gearing, or into a blade... A 600 hp chipper has a 1.5 m diameter rotor, with sharp blades, spinning in a housing... Open the access door, push on the rotor, and just slip a little tiny bit, and part of your hand gets amputated by those blades, with a 300 kg rotor... Speaking from experience, unfortunately, but fortunately, just lost skin on two fingers, however a couple of seconds difference, and could have lost all of the fingers!

I learned to operate lathes from large to enormous while still in high school, because my (very old) H.S. metal shop had scored many tons of outmoded machinery after WW-II. My shop teacher was a retired career industrial machinist / tool & die maker, and he had a seemingly endless collection of lurid, hair-raising stories of industrial accidents involving every machine there is, including a few we didn't have. To top that off, he very nearly had an accident himself in our school shop, while I was attending school (but not when I was in his class) from wearing a tie on dress-up day! I've had a few near misses with all kinds of dangers but I credit that instructor for making sufficiently paranoid that I am so far still un-blinded, still have all my fingers, etc. O_O

Quick correction needed: About 12:40, it's mentioned that speed of an AC motor is related to voltage, but it's actually determined by line frequency and construction.. 50 or 60 Hz line frequency, and the number of poles or windings, determine the operating speed..

Nice... I stopped wearing rings, even my wedding ring, at work, seeing how an entire finger just disappears into a mill, or lathe, or even just jumping down from a truck! With a big lathe, if a ring drags a hand a bit further, the entire arm is at danger! People might scoff, but anything that spins, has horsepower {or torque!} behind it, can "eat" a part of your body!

El controlador OT Fanuc permite maquinar ejes excentricos? (eccentric shaft)

love the quick notes with sharpie. When ever there was machine specific info that I would need, I'd just sharpie it on the controller.

On the 2nd thread that’s closer to the chuck jaws it should be done with a left hand threading tool holder mounted upside down. That way you can thread it with M4 (threading away from chuck)therefore you will avoid the awkwardness of ramping in.

oh man that text display takes me back to yeah, about 1992, programming a differential gear preloader that needed a small CRT (about 12") to fit the cabinet plus big characters for easy reading. I created a bitmapped font and bit banged it into video memory, each characeter was 8 'DOS' lines high and 7 characters wide, no graphics, just text, all written in C.

Your machine is wonderful!

1. imperial system is the worst bullshit i've ever been forced to work with - 3/8 diameter.. what the fuck does that even mean? i've to spend more time counting some fucking usa hamburger per mexican immigrants system numbers than making parts - just to have some fucking idea how big that really is, i've no fucking idea how big 3/8 or 0.375 is, when i get fucking us braindead larded drawings, i spend fucking 15 minutes before i rewrite all dimensions into normal metric system just to know what the fuck am i supposed to machine 2. whole fanuc and coding parts in G-codes is worst bullshit i've ever been forced to do - this system is just japanese cheap ass copy of original coding invented back in 60's, it's usable only for chinese sweatshops where they write program and run that bitch part in millions of pieces for decades, if you use that shit for single job production, you spends whole freaking day on some fucking dumb rod with 2 threads and parting and have 99% chance you forget some bullshit like G0G28U0 and send your machine to scrapyard before it even makes a single part, this shit is so fucking overcomplicated even for 90's, you must read a 500 pages book just to do a fucking thread and not to crash the machine - that decade systems like mazatrol were made, in comparsion to this bullshit it's fucking heaven
