- Incredible drilling technique on the Tornos Swiss Nano 7. How can you cnc machine a .008 thick hole into a medical device made from 17-4 PH Steel with a 44 Rockwell Rating?
With this technique I stopped breaking long drills on the Tornos Swiss Nano 7 to now get a perfect hole drilled into my parts.

It’s crazy to see something just a little bit bigger than a human hair cut stainless steel! This video was a blast to make! Big shout out to our editors for putting all the effort required into making this video!
Actually a human hair is approx .0032 so the drill is 2.4 times larger
Great work guys!
@@stevieg2755there are different sizes of human hair
That why they call them Crazy Drills, Mikron is the best for small holes that go deep.
@@stevieg2755Not all human hair is the same dia... It ranges between 0024" and 0041" in dia... Pubic hair can be as much 0053" in dia.
Interesting point about the issue with filming, when watching the video I didnt even think about it till you mentioned it. Charles
I have the utmost respect for anyone who works on that small of a scale. Excellent work!
Why thank you! 👍🏻
Thank you to the entire Titans of CNC Machining team for the amazing video! 👍 We hope to impress you again with our crazy micro innovations!
Thank you for the drills! They worked great!!!
Stuff like this makes modern life possible for us all. Such a cool profession.
Not only is this an insane part because of the small tools but you give some great info in this video Donnie! The test cut is genius. As long as you have a vision system that is lol
You pierced my heart twice with this one, once with the part, and a second time...with those baby blue eyes.
I hate you 😂
air also temp stabilizes spindle bearings allowing for proper preload
That makes sense! Thank you!
props to the camera team
I love watching Swiss machines work! The process is so satisfying
Seeing it next to the ball point pen was such a good idea. Dope video Donnie and Corey!
That Tornos Nano is, what appears to be, the pinnacle of "Swiss" machines. I use the "Swiss" for a reason. Go back multiple generations of "Swiss" machines til you get to THE SWISS MACHINE. All axis' driven are by a master cam that guides all of the axis' through a single rotation of the master cam. They were micro-machining parts long before CNC was added. Donnie: you've got to get yourself to a shop that still uses the OG Swiss machines. It would be really interesting to see a cam-driven Swiss next to the Nano
Those micro-drills are creep-fed, full-depth using opposed grinding wheels, similar to pinch turning. The carbide drill stock must go through an intense QC check. Even the tiniest inclusion would cause the "tink of death". That's if you could even hear the "tink".
Micron Tools are awesome, had a chance to meet the Team and the Workers are very proud to work there. to drill a hole with a 0.05mm drill is not easy and now you need to think the tools, team to make this drill. just crazy. donnie when you are next time in Switzerland visit Micron in Agno.
Love it!
I run .02" holes to .180" deep in Ti and can get at least 2500 holes done before the drill needs to be swapped out. All at 6k rpm, pretty amazing considering the rpm limit we have on our swiss setup. Tool centered using just some dials as well. Micro stuff is crazy!
Reminds me of the jets in a carburetor.
Crazy video Donnie! Awesome job!
Amazing work!
At 3:03 i was going to type comment how easily it can break. I got the answer just a moment later😆
Of course, great video as always, you guys rule!
Have only done this a couple times before but have done it on an EDM drill not great in terms of recast but it made those tiny holes where we needed them
Awesome video! From the amazing details given by Donnie and the crazy edit by Corey, well done guys!
Another good video Donnie! Always impressed with the videography and editing skills of your crew who are behind the scenes. So much work involved in these excellent productions.
Thanks ma!
Donnie makes micro machining larger than life! One of our generation's greatest machinists for real!
Literally insane, well done Donnie, super awesome video!!
This was really good Donnie with some excellent info. I think I still like really big machining a tad more but this really small machining is a world unto its own!
Great video Donnie! Crazy small😳 Also... Can we talk about how tight that camera was in there to get those amazing machining shots!? Shout out to Corey for the amazing camera/ editing work!👏
I'd love to have one of those Tornos machines. Great stuff here.
As impossible as it appears to center and drill a hole that small and that deep.....
I'd love to see a video on how they make the drill itself.
Dude same! I was going to actually say that in the video but I am confident no one is allowed to see that. When you look at these drills under a microscope they have perfect geometry. They look like a .5” (12.7mm) drill up close. It’s beyond impressive
@@donniehinske ....sneak in.
My learning about number drills happened years ago when I hobbled together two pieces of thin brass sheet material to make a holder for a drop in style polarizing filter for my Cannon camera lens. Those need to rotate.
I needed a small drill to match some small diameter brass " hobby stock " rod to make little roller bearings. A new specialty shop in town had some of these drills. This was back in '95 or so. I was amazed back then at the small drills... wondering how they made them.
Yours however, are much, much smaller..... yup, amazed once again 🤯
I'm a tinkerer, not a machinist.
@@randywl8925 Look up spade drills. Many years ago I was into making propane burner jets for model boilers. I drilled .006" dia. holes with a home made spade drill I ground from a pierce of piano wire. For brass this works well.
It would be great if you could go over the ejection of parts that small, what prevents the part from being damaged? Especially something like that part that has a wall thickness of .003”
I worked for a company 20+ years back that had the record at the time for the smallest hole "drilled" at time. It was .002 diameter. They had a huge collection of tiny Agie sinkers that were still functional but getting hard to get parts for! So my genius buddy designed and built a them a new power supply to replace the old Agie OE! Scary smart guy!
Good video Donald!
Respect!
Also did this kinda stuff on a Schaublin 125-CCN. But with smaller drills. And external powered spindels. But it worked.
Most precise machine I've ever worked with!
Also swiss made. They rule.
Perfect Synergy: Swiss Machines and German Tools!
Btw. PH Horn, Kennametal, Iscar and ARNO rule!
(Oh, and Britsch of course).
Excellent work. Your videos are always visually pleasing. 😃👍
Vermont Microtechnologies has been drilling micro holes for decades. I worked there for ten years and saw some really small stuff. Crazy cool 😎
The company I work for specializes in medical micromanufacturing. We machine Ti spheres with a diameter of .013in and cut/weld hypotubes with .020 OD and .014 ID. All of our work is done with lasers and microscopes.
That sounds crazy man!
@@donniehinske That's what I thought when I started the job. The scale is normal to me now haha.
Tornos for the win! Great video Donnie.
I drilled 6600 0.2 mm holes in carbon fiber for a lighting affect on Mclaren Speedtail sill panels, the mclaren logo lights up when you put the lights on
That’s super interesting!
The craziest part I ever made was when I just learned how to lathe, it was a 316 Stainless Steel part, a transition ring with 0.005’’ wall thickness, and 0.005” holes on the sides milled on the 4 axis, I did tons of attempts until I finally achieved the process, so delicate you could scrap it with the minimum force in between your fingers. I did it on a Tormach 8L haha
Very cool! I would now like to see how that drill was made😃
This guy is obviously super intelligent and always hilarious 🇦🇺👍
I drilled (not EDM) down to 0,08mm some 25 Years ago. Standard Guehring Twist Drills. My second go to drill brand is OSG.
As impressive as this is, it blows my mind that there's a process to make drill bits out of carbide that small. Ps the camera shots were stellar
I have been around different types of swiss machines and as they warm up we have noticed some drift in diameters and lengths, how are you ensuring that the spot drill when you set you center it is at the same when the machine is at operating temperature?
From everything I’ve seen the nano is insanely consistent. I haven’t really gotten down to the .0001” increment with charts or anything like that however with this part we ran 100+ for this video out of stainless and brass. It never broke a drill. My handling of them was the only issue 😂. I know that doesn’t fully answer your question but it IS all I have for now
To anyone wondering: 0.008 is 0.2mm in normal units.
i enjoyed my time as a machinist but i eventually found my love as a tool and die maker. these are great videos.
U are 1 in a million machinist
Thanks for the video, does that machine have a live or fixed guide bushing?
I have always wondered about the part ejection process for Swiss machines. Particularly with this part. If you just drop the part into a basket how likely is it that it lands just so that the delicate tip gets bent or something? After seeing bigger CNC parts be handled with great care to protect surface finishes and whatnot, just tossing finished parts in a bin seems odd. Any thoughts?
Yes! Good call! That was actually the customers biggest concern with this machine. Really our solution was more trays to land in. Due to the way we manufactured the part luckily they will land on the big end. With the Tornos TMI screen we can select how many baskets are in our part catcher. This will allow us to 3D print smaller baskets so each part gets its own Individual landing spot. That’s NOT the only way to do it but it’s a way that I thought would be easy
@@donniehinske You could partially fill the container with oil to dampen the part's drop speed.
@@BasementEngineer when actually running the part oil does fill the container
Have you guys ever shown how they make .020 or less coolant thru drills? Bot sure they make less but we run .020 all the time. Blows my mind how tiny the holes in it are.
thats impressive .
I've done this type of concept with a 90s TV and a mid range qc microscope on a hardindge super precision.
Работаю на швейцарских Nexturn, делаем системы имплантов для стоматологии. Эти станки прекрасны. А ваше новое поколение вообще кайф. Возможности подходят к физическим пределам)
I would circle mill it with a .004 endmill with a .00006 step down
I like your skills
insaneeee
Did some 0.12mm (0.003”) in heat treated inconel 718 today 👍, not actually as hard as one might think.
Got a question, why drill a hole then turn the OD? Wouldn't you first turn and then drill usually?
The videographer and editing staff need a shout-out. Not this video, every one of them.
How about in the next video, you end it like the Star wars movie credits scrolling up the screen, music and all.
....or, let them read my comment to let them know they done good 😉
WOW. That's tiny. I'd like to try that one day. I thought drilling PCB testing probe holes for sockets for PCB fixturing and program testing were small. Most range from .069" to .032" This is EXTREMELY TINY.
I drill the .032" at about 2750 rpm but
So 6 ten thousandths is literally dust. lol.
Broke a drill with your finger just to prove a point, awesome video
Hi Donnie, What camera are You using to get such a Great Pic??
Great video. I know I will catch some hurt, but atleast add on screen metric dimensions
We used to do that sort of thing with EDM. We had the capacity to run at 30K and had the drills, but EDM was better in 1987
Haha, I was going to say don't breathe on it or you might break it. I think the smallest I've done is .011 or .014 can't remember now.
Drilling that hole seems impressive at first, but then you realize someone made a .008” carbide drill.
Because of the thumbnail saying heart piercer, design and make some slugs for taofledermaus
hope this is only the beginning of nano machining. just boggles my mind how watch makers or medical make such small parts. how it can even be cut
Try drilling the hole into a proper medical alloy like for eg. cobalt chromium!!
i understand the centering concept But with your shop and employees why do you send this part to outside processing for centering #
For test cut/hole to work one needs to be able to find hole. Amazing what was feed rate?
60 SFM (18 SMM) -> for 0,008'' drill (0,2mm diameter) its 28 648 RPM [revolutions/minute].
Guhring recommended Feed Rate (IPR - inches per rev) for 0,0063 inches diameter drill (0,16mm) is 0.0004 [inch]
So its around 11 [inch/min] ([286mm/min]).
I was using 0.1, 0.15, 0.3 and 0.4 drills and the 0.1 was the nightmare.
I needed to go 0,5mm deep with them, each part with different hole diameter (prototype purpose).
Broke x9 0.1 diameter drills and 0 others HSS-E-PM drills in Stainless 304.
It was challenging, but doable, even with 5 000RPM only hah
what is this part used for?
why not wire edm?
Because you can't make a hole like this with edm.
I wonder how they make a drill that small
Wish they explained what the medical part was for.
ok i would love to work there, maybe you need someone to sweep the floor? =)
at 1:52 you are saying "this is where you control your RPM", why can't you control the RPM like your main spindle on the computer in the front, when you can call them via a M-Code?
There are high frequency spindles that can be controlled like that.
I can't do that with my Dewalt drill ?
Try drilling a 0.05mm (0.0019685") hole in stainless steel on a Bridgeport milling machine. Talk about pulling your hair out...
Then when you get it drilled you can't see the hole unless you hold it up to the light. And you need a microscope to see if your drill is broke or not. Concentricity is a killer on a drill that small. 0.0001" runout just isn't going to work very well.
I would NOT want to try that on a bridgeport
Babe wake up new Donnie video dropped
Why aren't You rotating the material also?
can you drill 0.05mm b I did haha
I do .010 holes manually with a quill.
KERN engraved on a human hair...
Even though I've spoke English my entire life, I had know idea what he was says half the video.i spill watched the whole thing though..
8 thou is not microscopic
I produce medical parts with my Citizen lathes.
That's not microscopic, that's at least average sized
no for real tho, we drill way smaller holes
I’m sorry but man nah your just nah I can’t
cant stand ths guy, i know hes good but idk something in his eyes
edit: how can you join and pay for a channel that is clearly a multimillion company. with goverment grant probably
Love your channel but .008 inches is hardly microscopic. I've drilled .0037 inch holes on multiple occasions and they are clearly visible with the naked eye.
I made a part on the nano once that had a .0035 thou through hole with a .008 thousands diameter up to .0125 diameter at .012 thousands in length
Very challenging
