Titanium Screws are DONE!

- We're making titanium screws! The Tornos cut the cycle time in half, and we're super excited that we can finally catch up with all the screws that are needed to complete our knives. Stick around till the end when Jo shows off the knife-pocalypse upstairs. Hint: there's a lot of knives that need to get screwed together.

I needed to shorten 3 screws today and while using a reinforced cutoff and a 1/4 hp pendulum motor I could lean into this screw enough to stop the disc! 🤔 No sparks. Brown tempuring. Weighs less than a dime. This has to be some of the titanium right? So I wanted to see someone cutting titanium screws and wound up here and wow. Idk where mine came from but I now have a much greater appreciation.
Cool little machine. Interested to see how the tolerances hold over the run period.
Within microns repeatability for a relatively small batch of 1500 parts on a sliding head. You could even have a macro program to adjust the offsets after every so many parts if needed for added reliability of the tolerances.
What are your plans for those unmachinable drops? It's kinda painful to see that much material go unused.
Amazing machining
Thanks John. I have long wondered what the Gcode for such a machine looks like. Please show the code from the Nak that does simultaneous back and front machining, I am very curious how it co-ordinates the 2 spindles.
As it does not have two turrets there should be just one code that it is running through. So this machine is not able to do simultaneous back and front machining.
I would think... You could make a small FORTUNE selling just your Ti screws.
Think of how-many-people, that own pocket-knives, would buy them.
I would be one of them, for sure ! VERY impressive machine, John.
Looking GOOD...
Screws are dirt cheap tho. Would not be much profit and who would pay for custom ones so much?
@@modris2980 you would be surprised, there are companies that sell titanium bolts for motorcycles to replace the stock ones. They charge between 5-12 USD per bolt depending on size and how many are in a kit.
Good work John. I like my norseman screws
3:50 Chopsticks! Seriously, something Grimsmo I might actually be able to afford.
Hi John, I'm doing dental and medical parts on this kind of machine. Would be interesting for me what kind of cam software u use?! Also if you are struggling on some point don't hesitate to ask! I'm pretty much studied those machines 👍 BTW nice videos! Cheers Fabian
Wondering, what titanium alloy are you using?
The aircraft alloy I am familiar with is 6 AL 4V.

You really need to add a visiport to your swiss lathe. It would be nice to be able to see it in action instead of just oil covered glass.
My guess is with 2000psi oil blasting out everywhere a visiport wouldn't work very well anyway.
The oil is probably too viscous for one
Are you planning on using the nakamura to run the remnants? If not you may want to crunch the numbers to determine if it's worth it.
It's a complicated mathness.... while saving 2 minutes causing remnants, the nakamura is then able to spent 3 whole minutes doing non-swiss stuff.
Assuming that endmill for milling the torx is 20thou or 0,5mm diameter: Just wondering why you are running only 20.000rpm. That is only 31m/min. Maybe you have tried faster and it doesn't work. It seem there are a lot of time to be saved on that milling cycle, when apparently there are both torque and speed in reserve.
Hi John, could you include some close-up stills of your brass and titanium screws at the end of the video? Thanks!
John, maybe you discussed in different video, but what made you go with Tornos? Currently looking at different brands and was curious what swayed you to them. Thanks
Very cool machine. Only down side is the limited number of tools. Once you get good at setups what is the anticipated setup time for a new part?
I just picked up Norseman number 2553 from my local knife shop. It's my first Grimsmo, and I fuckin love it! Even though it's pink/fushia/purple LOL
Those are amazing machines, but you've clearly found a design issue they could address (maybe the bar feeder is not by Tornos?). Likely to run into the old bug vs feature argument, but that wasteful chamfer really should not be needed for normal operation.
Hi, how many can cost , per screw piece ?
Can you make all of the bolts of my mio sporty with titanium
if you dont want to find out what a titanium fire looks like,might wanna not use high pressure coolant ,id send you my video of a citizen fire i started making Ti screws if i could.
08:34 Canadian translation of Stefan Gotteswinter's "Uurgh!"
Why don't you record that sound and send it to tornos support?
Since brass "cuts like butter" and is a cheaper material in general, ide love to buy a deeply discounted "brass edition" Norseman, assembled out of your "test" peices. I don't care if it's heavier. I'm not going backpacking with it. I'm going to work. Combat the clones. [🇨🇳👎]... [🇨🇦👍]...
You want a brass knife?
@@47EZ_DRIVER Sure! Not a brass blade. But brass handle scales, screws, pivot, standoffs, and clip would be cool.
Funny thing... Tornos means lathe in Greek :D
Yep! ;)
@@tornoschannel So I take it Tornos will never make a mill?
@@tomrevere9091 We do have some mill www.tornos.com/en/content/milling
6:41 sticker means : I used to have 7 fingers, but 2 of them got cut off right here.
How this lathe is measuring tool wear ? As far as I understand it doesn't have a probe right ? Do you stand next to it and check every single bolt and then manually change the tool offset ?
The probe is not used to measure tool wear. You have to do that by hand with a micrometer because the probe is not as precise. But you dont have to measure every part its more like every 10 or 20 parts depending on your tool life.
It's a swiss lathe they hold size really well so inspection can be minimised to a point
06:04 a little HF action for the Win!
Mine has served me well.
Computer programming is far different from doing the work by hand, otherwise good work.
An experienced machinist knows that jewelry and watches are a safety hazard!!!
What's your point? You don't think people know that? Some people take on risk even when its a hazard. Choices People make choices. It has nothing to do with experience.
@@theindustrialartist3810 My point is self explanatory you DOLT!!!!!
True, a major hazard on manual machines, but this one won't let you get anywhere near a spinning part!
Not sure how other people feel, but, I find RUclipsrs holding a camera in one hand and working with the other hand VERY annoying!
for average people yes, I find it annoying, but John is one of the more steady holders, and maybe a bit of software is helping too. shaky video makes me dizzy so I have a low tolerance and tend to shout "use you fancy machine to make a tripod" at the screen (-:
