Thank you for showing an EDM wire doing something other than making parts that disappear flush into another part. I love these machines
why is edm being used here? tolerance reasons? seems like a whole lot of work
@@janek_ow5076 Surgical tools like these are extreme precision devices, so yes. These are going to be used inside someone's body, possibly for very delicate work; so they should do the job correctly every time.
Late last year I got see parts that I made enter a human heart and save a mans life. So far 800+ people have had the same procedure done. They have a 97% success rate.
Now that’s badass!
Out friggin standing!
Amazing! They are much more than just parts, aren’t they?
Name of the product ?
@@trevorgoforth8963 Absolutely.
I've been a machinist now for over 35 year. I use to teach an a local ATC. When they high school students through on tour one of the questions that was always asked, what do we need machinist for? The answer was very easy to give. Everything one touches on a daily basis a machinist has been involved one way or another. I so miss programming and running wire EDM's.
Been around machining 40 yrs myself and EDM is the most mind blowing thing to me of recent innovations. Only those of us who were there in the early days can TRULY appreciate this level of awesomeness.
I work for acompany that produces components for lapriscopic tools. We produce the main bodies, levers, buttons and knobs. we also over mold some of the probes that are used. We also produce tubing kits for endiscopes, various housings and components for trolley assemblies. The only problem I have working in the metrology lab, is the large volume of work that comes through. A shot of 4 parts every hour until a batch of 50,000 parts is complete, at a rate of about 400 parts an hour. Then an AQL inspection and full set of measurements on 80 or more parts from the production run.
We have 2 EDMs in the toolroom that produce the mould tools, 1 wire, 1 sinker. The mould tools often have different dimensions than you would expect given the dimensions of the final product and can often take a bit of fine tuning.
Afew years ago my grandfather had to have surgery for a bad heart valve and from what I understand they essentially had to inflate a small balloon inside his heart to re-open the valve. It exploded inside his heart and the surgeon had to go in and pick out all the little peices, he ended up being fine. Still kicking at the ripe old age of 90
sounds like a transaortic valve replacement
Holy shit
This machine is bad ass, its capabilities are insane. 👍
Wire EDM is probably my most favourite CNC machine. Ever since I first learnt about them a couple years ago my mind is still blown and the precision and complexity that can be achieved. It’s also reassuring seeing a genuine real word use for a Wire EDM machine, outside of making seriously cool (albeit novel) zero tolerance flush cubes
Mech. Eng., Used to work in a company designing tools like that (grippers, needle holder, hooks, scissors, etc.) CNC is so crucial to the success. Great video, liked it very much
Swiss and EDM content has been great. Great vids and great hosts
Thanks dude!
It is very inspiring to see such a machine being used not for the sake of some decoration, but for truly worthwhile purposes.
EDM machines are my favorite out of all CNC machines, its just so fucking cool
As someone who has had laparoscopic surgery, i can appreciate this
For the price we pay for surgeries, you'd like to think each and every part is a titan CNC machined part.
This is one of my favorite how-something-is-built type videos. Very interesting process, interesting product, and excellent narration. Well done.
Watch you guys while I’m not busy at work. You solve all my questions about CNC machines and how parts are made…. So cool 🔥
Is that a lightsaber sound @1:33?! 😂 good video Trevor!
Maybe 👀
Already we tried this type of jaw cutting technique before 12 years
N still we are doing in reusable Edm wire cut machine
Even we make it in Swiss type machines
Great job bro
I am one week Post - op from laparoscopic rotator cuff repair. Seeing how these, I’m guessing clamp heads, are manufactured is absolutely phenomenal. Thanks for showing it.
Had those inside my shoulder for about an hour or so back in March. The damaged couldn’t be repaired that way so they stopped and picked up a knife.
Very nice.. I'm surprised that that tooling setup doesn't have a 90deg. indexing facility. Or maybe insert a 90deg angle adapter between operations.
Very nicely done. Never did a stack of parts like that in the EDM before
Cool video. I love watching CNC machining videos, and my wife is a laparoscopic surgeon. You should mention Kurt Semm, a toolmaker and surgeon who made modern laparoscopy possible by making his own instruments.
That's was beautiful!
Manufacturing is always❤️
Really awesome that you guys put a gopro inside the machine.
Aah okay - I missed that part - thank you for answering Trevor - I really like your content - that machine is as impressive as any other there - thanks again...
Those are some good looking parts; pretty cool.
Well done
Great parts for great surgeons who save great number of lifes
That’s neat. I just had my shoulder done, so been looking at lots of stuff about this type of surgery
Great video. Thanks!
Modern tech is just crazy good stuff! My gf had an impella device installed in her heart 4 yrs ago! Just this last sat. i got her back from the hospital again! They were going to install another impella but didnt need to thank god! Its such a tiny device or pump ! Incredible stuff like that can be manufactured!
Are you trying to say "impeller"???
Thank you.
It never crossed my mind, that mordern medicine and technology are so interconnected.
That opening went so hard
I have underestimated this technology I think. Amazing results and very interesting to watch.
I'm surprised the Mode 30 cuts don't mess with the GoPro. Cool to see.
Outstanding video you guys! Kudos to the editor 💣
Thank you !!
Beautiful!
Fun fact, historically many surgeons were often skilled blacksmiths, because by necessity they needed to create their own tools and instruments.
Another great one guys
Sorry to be picky but it appears to be a QR code, not a RFID tag. Or... is the RFID tag under the QR code? Regardless, EDM is such a cool process. Sure has come a long way in the past 15 years or so. Fun to watch especially the way you cut this video together. Well done!
Edit,: Sorry I just noticed when watching again, there is a QR code AND an RFID symbol, the tag is under the label....
How do you price using the EDM machine? Hour of use? Number of parts? Number of operations?🤔🤔🤔🤔🤔🤔
I charge them as a cross section area that wire cut like x₹ for cut area mm²
Wow !!! Incredible.
I am a founder in a startup company that makes advanced geometries in laparoscopy and electrosurgery! We also use EDM for serrations but for the jaws we use HMC turn-mill centers as our jaw geometries are much more complex.
We too make laparoscopic instruments
That was very engaging to watch.
after the holes i like to go for the slots too!
Ayo if a surgeon ever fcks up and sows me up with an instrument still inside of me it better be a damn Titans of CNC machined piece of art.
😂😂
It still amazes me how easily these machine produce really complex parts even though I have my own Mitsubishi MV1200S i could watch these videos all day Trevor 👍The RFID on the spool is a great idea. I wasted some parts once running 0.2mm wire on a part programed for 0.25mm once 😂😂
ouch !
you have manufactured some excellent looking laparoscopic box grasper jaws. I was a Sterile Processing Technician for a few years while I went to school for surgical technology so this tickles my fancy quite a bit. A little too much bulk imo to be up to snuff for manufacturers like Mueller and Aesculap ;) but bravo!
I love the tracks used to this vid❤
Incredible
STOP YELLING AT ME TREVOR! Lol great video! That's awesome man, great job!
Lol sorry I had some nitro cold brew before filming this one 😁
This machine is awesome.
When you are doing the op before cutoff, are you running a higher wire speed? Essentially you have an interrupted cut then and isn’t the wire being degraded from the top to the bottom?
That alloy has a nice vibes
This is so beautiful man wtf
When cutting the parts of, do you weld them stuck again to the holder? I’ve heard Mitsubishi (MP1200) has a technology which can wireEDM and weld gaps at the same time
Very good and informative vdo bro, thanks for loading this Hope to see more like this in future also..GULSHAN Kapoor from Delhi, India
❤wow, amazing 👏 😍
Incredible technology.
So more advanced then when I was a Tradie using carbon blocks and oil baths
best of the best
So cool 😮
from someone with no background in machining, i’m really curious about the CNC. So is it essentially like an electronically charged wire that cuts similar to a plasma? Wonder what the gauge of that 316L wire was and astonishing how it held up to that type of cutting!
Lastly, i wanted to clarify if you were saying that the alloy of the cutting wire can effect corrosiveness of the part it’s cutting ?!
does it really make light saber sounds when you turn it on?
1:30 lightsaber no wayyyyy😮
how do you compensate for the bow in the wire as you feed ? from top to bottom in deep cuts
When are we getting the EDM academy?
I love EDM used to drill holes with it in 2011 for lab work. That being said... Robo mechanical arms for surgeries do not require wire edm precision. Lol
For clarification the parts they're producing are "disposable." The vendor requirements for replacement and service is very strict. A good thing for the medical industry. But... It's not required here and just inflates the medical bill for insurance companies and patients.
Why?
Because the medical equipment suppliers need to follow standards for equipment for their insurance. 💫😵💫😵💫
Dizzy yet?
Cool vise : D
Interesting. I design mechanisms that often require EDM for manufacturing.
I was always under the impression that operations like around 5:20 were very hard, if not impossible, as the coolant cannot neatly flush through a single channel. I guess the technicians were wrong, and it can actually be done.
Are those tumbled for deburring or what technique is used for that?
Trevor is it possible to have a video showing step by step how yo program in MasterCAM agie Charmilles
My fear with that RFID spool is that the machine might be programmed to refuse to use a spool from a competing manufacturer, or to prevent reloading the same spool or moving the RFID tag to get around that. I know some 3d printer companies do that.
Ok, so 2 questions here (I’m a doctor so very familiar with laparoscopy) but how does the EDM make an enclosed pocket (it seems the wire needs to be across the part?) and related how did you cut the tabs across the stock but leave the parts attached? Like if you cut across with a band saw (which EDM seems like the sci fi version of?) you would have dropped the parts into the bin below?
Haha great questions! The enclosed pocket is accomplished by drilling a start hole, feeding the wire through, and then cutting the desired shape of the pocket.
The parts stay attached after cutting because I left a .010 tab so the parts didn’t fall into the tank. Sorry I didn’t mention it in the video!
@@trevorgoforth8963aha that answers my question for keeping the parts attached, Mitsubishi EDM machines can weld with the wire so the drop-out part can be lightly welded to the holder en be broken out afterwards
@@MW11- Yeah GF has slug welding options as well, we just don't have it on this machine!
Make a lot of parts for Medtronic.
If you get bone surgery, we probably make the parts.
would have been interesting to be explained in more detail how this actually worked and why this method is used etc...
Were do u get those holders for the wire machine? They look so much better than the table vises we use.
System 3R (also part of the GF family just like AgieCharmilles), we use pneumatic ones, so a robot can change holders and the machine can run 24/7 (as long as it has thread)
How does the wire cutting make pierce cuts like holes?
1:30 is that where the lightsaber ignition sound was derived from?
I'm surprised the manufactures haven't come up with a rotating head for the wire, although if the parts are small enough the bed could also rotate to some degree.
Hi Trevor/Team Titan, I remember in another EDM video you mentioned a paste of some sort which help cleans the brown looking finish off of the parts could you remind me what this was please. Thanks for another great video. From Tom
We use both Nevr-Dull wadding polish and lime away. For these parts I used lime away but you have to be very careful because it is aggressive. Dilute it and rinse thoroughly and immediately after washing. Also, use cold water. Hope this helps!
@@trevorgoforth8963 Thank you Trevor I will definitely give this a try. keep up the great content!
Is there a video explaining the machine?
i take it since the wile spool is being collected under the machine and since its the sparks and not the wire doing the cutting that the wire can be reused for more cuts than just the one time
The wire will be corroded, it’s cut up into tiny pieces and recycled
Yes it's waste once used then recycled. A wire processor on the back snips it into tiny pieces. I ran Mitsubishi FA and FA/V series wire EDM machines for over 5 years. Usually we used .012" wire but can go all the way down to .004" with only a little over .001" over burn, so if needed you can cut slots down to .006" wide and ID corners almost perfectly sharp with a .003" radius.
Great video 👍 Amazing and to think this type of surgery will only be available to those that can afford it 🙄
*except for in all other developed countries outside America
I’ve got an angle grinder at home. Basically the same thing 💪
Please how do you start the hole
How are these parts deburred? Tumbler?
*BEAUTFIL MACHINING*
Sir can you tell part name.
How is the start hole made, a drill?
An EDM drill, also known as a hole popper. Or you can drill them using a mill or drill press.
"We maintain a gap between the electrode and the workpiece where the spark is created. It's noncontact machining," explained Dave Thomas, president of EDM manufacturer Sodick *(not the Wendy's guy apparently)*
May I ask how much that part costs? I mean this is a secret but around how much? Considering technology / time / total batch size? its like 500 dolars per 1 tool? or magnitude more? ~ Just curious..
There are 42 grippers made out of this block. Let’s say it takes 20 hours to make them. Even at 120 bucks an hour shop rate that comes out to about 60 dollars a piece.
Probably double or triple that. Surgical steel is very expensive just for raw material and extreme accuracy multiplies the part cost. EDM wire can cut to microns. EDM machines can be a bit slower for cutting feedrate, but you save when you can cut multiple parts simultaneously using repeated pattern geometry or if you can stack multiple parts at a time using a higher head height. I used to cut stacks 100 to 300 sheets high to machine gaskets for pipeline parts. Also not much tooling needed for EDM reduces cost. Just need wire, resin tanks, and dielectric water filters as opposed to numerous endmills, drills, treadmills, and facing tools and the collets and tools holders needed. Sorry I'm blabbering lol
@@trevorgoforth8963 thanks for answer. I really thought it would be much much more expensive given the application but wow. That is quite impressive pricing.
Question: why don't you do the ruffing with milling and then go to the EDM?
You can but there isn’t much need to. Square block there is a better seal for flushing with the water jets so it’ll cut faster. It’s also unattended machining time. Either run lights out or run another machine.
Because after you rough it out with an endmill you'd have to rough cut the initial wire cut anyways to get the proper distance for voltage gap and wire tension for a proper skim pass cut. And end mill would be like using a chainsaw for a surgical cut and the rough cuts for EDM wire are only a few , usually .005" to .010" , off the desired profile or geometry of the part.
@@aguillot1984 ow didn't think of that :) very good answer. Thanks
I do not understand how the wire is able to cut a blind hole through the material - how does it accurately make the blind plunge ...?
The wire doesn’t cut blind holes. The start holes are made using an EDM drill or mill. The wire has to travel all the way through the part so it can’t cut blind features. Sinker EDM’s however, are used to EDM all kinds of difficult to machine blind pockets and holes.
Toothbrush is a handy tool to keep in your Top pocket
Hur gör metoden hålen utan en ingång i materialet ?
Edm cutting is cool. But damn it’s a boring process in the trade
What do you mean by that?
Great video, please volume down the music or ditch it all together.
Jeebus this looks like sci-fi.
Who knew saving lives could be so edgy and sharp! 🔪😷
Rocket technology is always contributing to medical technology and vice versa
what's the price of this machine?
