@@machinist7230 OMG same here, I did about 95% 6061 and a mix of 6AL4V and random superalloys. The one single 17-4 project I had was a nightmare from beginning to end.
Right. When he took the passes on the spring mechanism and went like 'eh, wouldve been faster on my other machine' i was like tf. I would have been scared of this thing breaking off already lol.
Apparently I now love household items that look like Lockheed Martin would have charged the military six figures for. The idea of a some kind of helicopter part hanging out in a kitchen drawer is just hilarious. In all seriousness I'm really really curious what a reasonable price would be for a one-off tool like this would be. It's an expensive material, seems like a bunch of operations, custom fixtures, and hand finishing. I know almost nothing about the machining industry so this is all magic to me.
17-4 PH900 is probably my favorite stainless to work with. Made alot of gun parts out of it. Always loved the surface finishes i could get out of it. Excellent work!
I thoroughly enjoyed this and all of your other videos. The demonstration of the utility of an engravers ball vice alone was worth the price of admission. That sweet little 3-D printed scissors jack was brilliant as well. A CNC mill is a bit beyond my budget though. I guess I'll just have to settle for shelled walnuts. ;-) Cheers and Happy New Years, F.C.
Fantastic -- I'm learning a ton from these videos. Your integration of 3D printers in your workflow is really interesting and inspiring; definitely making me see my FDM printer in a new light.
Right..? I just cannot believe he doesn't have 3M subscribers ... and instead, I have the luxury of Adam occasionally even seeing my comments because there's less than 200 ... instead of what he deserves ... which is like 30,000 comments (as I'm sure his content will eventually have).
I like seeing your more artistic work (though it is undoubtedly a functional tool). Wonderful to have household items that are also engineering novelties. Thanks for spreading holiday cheer.
Flexures are very interesting and have the potential to be superior in overall performance, as in this example. In this context, it's essentially replacing a rotary bearing with a compression spring, so there are fewer parts, less friction, less wear, and no assembly required, all while the flexure operates well within the steel's fatigue limit so it practically lasts well over one's lifetime. Now imagine bearing systems that can be replaced with flexure components--the efficiency improvements will keep stacking with each replaced part. The downsides are that it's more difficult to manufacture and it'll cost more. But tools like this are worth it.
Awesome work as always! I’ve been doing this stuff for 35 years and I learn something every time. I’ve really went nuts with super glue over the years. I use it a lot. For parts like this that are delicate in the soft jaws, adding a few drops of glue can keep them from springing in. I also usually load the bottom of the jaws with some stacked up aluminum scrap that’s the same thickness as my part to keep the jaws from creeping in as top pressure is released.
I wish I had one of those sized for hazelnuts, I crush the meat and send bits of shell across the room almost every time I open one and a nutcracker with a hard stop to it's range of motion would be perfect. I don't have a cnc so the best I could probably do is put a tapped hole in a regular nutcracker with a machine screw to limit travel.
Very cool little project! I was really surprised you milled out the flexures and profile - I thought for sur this was going to be done on a wire EDM. thanks for sharing!
Great content, really enjoyed it a lot! Also really envy the way your work/life style. As a CNC guy myself, I truly wished that one day I can be like you, working in my own home shop and appreciating creating something in machining at last.
I am but a fabricator But I too use 3d printed parts for welding fixtures like that little jack Between my welding table and printed fixtures it can really speed up workflow as well as increase accuracy
Thats the difference between something that looks like a medical instrument finishing wise (the nutcracker) or something that looks like mass production EDC items with the media blast/tumbled finish.
@@besenyeim Got to disagree with you there. Aesthetics are subjective for sure, but for me that brushed finish screams "quality" in a way that a flat matte tumbled finish could never do.
This is also called a "compliant mechanism", which you probably already knew. Have you seen the Zenith Defy Labs wristwatch that eliminated about 20 or more parts by using a one piece component with a bunch of flexures? I never would have thought of a nutcracker. That is soooo cool! 🙂
I sometimes use a pink block pencil eraser to wrap the paper around. Lets the paper push into the block on the high spots, and smooths out the finish some.
You are a good designer with manufacture ability as the base, I run a high precision machine shop and find a lot of gap between drawings and machining which if narrowed will reduce part cost.
When hand polishing with a dowel I put rubber hose on the outside of it, like fuel line. Lets you still push and guide where you want the pressure but also has some resilience. Charles
Very nice design ... but two parts connected with an insert of spring steel would make milling a little easier and give you completely new design choice.
I really love watching your channel. My passion in life is machining, and I have been a mill CNC programmer for a very long time. Foundry production tool and mold work is my favorite. Right now I work in a job shop which is more lucrative (you wouldn't think) but it is. Thanks for the great content!!!
That is incredible work to be honest. Can you kindly explain more on that lack of "tensioned z axis screw"? you mean like a pre-loaded double ball nut arrangement? or like a counterweight?
Also cool for print-in-place metal SLS manufacturing. I wonder how strong the hinge is at torsional stress. Using additive manufacturing the strength could probably be increased.
Subscribed! You're a very impressive machinist. I like flexures, and I like your Nakanishi micro motor. We have a few at work. Very pricey, but worth it.
Hi Adam, i love your work and as a fellow hobby/work machinist i truly appreciate this craft you share. I have a question: i'm tired of the relatively poor rust inhibiting performance of my BLASER coolant, what is that transparent coolant you use??
At 7:20 when you refer to cuspping, is that a slight indent where the fillet transitions to a flat? I'm currently trying to prevent this in my own work.
@2:13 you talk about the mark that the tool leaves due the machine not having a tensioned Z axis screw. How does tensioning the Z axis screw eliminate it?
There’s less vibrations and more stiffness . Most mold class machines at a minimum do that or have even more sophisticated approaches to get really smooth motion
Smart looking project looks the part, Adam. Would your Haas handle 3d profile machining on small dies like in plastics dies (accuracy over speed)? I have seen a Doosan (DEM 4000) with a Mitsubishi controller that has thermal compensate and wanted to know your thoughts? Happy New Year and hope to see more of these videos.
As long as you stick with contour or waterline strategies , where the z axis doesn’t move . I’ve gotten very good results in the past . Now the Mori seiki handles the small 3D work
Good to hear. How do you find using cutting oil instead of cutting fluid mixed with water? Here in Western Australia, it gets hot so maybe an option. Thanks for the feedback.
It gives very good performance in small tool work and hole making. It’s not ideal for high volumes of metal removal as its capacity to cool is no where near as good as water based options . Maintenance and top offs is nonexistent though
Does the haas make much noise in your work space with toolchange and air? I saw your neat workshop in a NYCNC video. I am looking to do similar. Thanks
@@hawkprecision7878 the machine itself isn’t to bad , it doesn’t use much air to do a tool change and use no air when operating. It’s a little noisey at 10k rpm but most my work in this machine is much slower . The Actual air compressor is the loud part of the shop . If I had the space I would have a dedicated sound deadened area for it
Nice work, i want to ask how much electricity and overall cost of making the part is. I love the concept of 3D printing and CNC but i always assume it's way too inefficient to make novelty parts like toys or nutcracker in this case. I'm really just curious if it is a viable solution to buying new gadgets or is it just done for fun?
The electricity might have only been a few dollars to machine this. The Shop Generally has a 200 dollar month power bill with all 3 cnc machines running . The raw material would be rather expensive at around 50 dollars to buy, but I had it left over from another paying project. In general , its not cot effective to machine something that you can go and buy. 3d printing is different, much cheaper to get a part. Ultimately , the real power of machining and 3d printing isn't making things cheaper than what you can buy them for , but making things that don't exist in the market place

Enjoyed it a lot!
You know how much i love seeing benchwork done. Its its own art and i always appreciate seeing it done over tumble/media blast.
the man himself 😎
Spoken like a German craftsman!
You know you're a toolmaker when you call 17-4PH in H900 condition "a pleasant material to work with".
Nice work, as always.
I actually got an eye twitch when he said that - 90% of what I work with is 6061..🤣
It really is a pleasant material to work with.
@@JFettig111 i agree, much nicer than aluminium for me, because it isn't gummy, and it surfaces well

Never underestimate the ingenuity of a machinist with an engineer's mind.
Great video.
"with an engineer's mind" - he's not putting toilets in the hallway OR cable tray through a steel I-beam.
Absolutely beautiful design. This sitting on the shelf at a high end home goods boutique would make everything else look cheap.

That's really sharp looking. Nicely done.
Always learn a ton from your videos! Happy new year and thanks for all the work you put into sharing your knowledge.
Adam, The nutcracker is not only functional but a beautiful work of art too. Can I be your brother in law so I can get one 😊 👍🏴
Thank you for explaining the Z-axis ripple.

I bent / broke so many nutcrackers cracking macadamia. I would recommend that for torture testing.
Beautiful work! Really like the videos.
Nice! I really like the jack, totally gonna steal that.

Forget that belt grinder, I'd take a media blaster or tumbler over that any day! No hand work for me!
Not just the work. The finish from both of these is more pleasant for me. This nutcracker, with a silky sheen from bead blast would be gorgeous.
Thats the difference between something that looks like a medical instrument finishing wise (the nutcracker) or something that looks like mass production EDC items with the media blast/tumbled finish.
@@StefanGotteswinter best alternative IMO is to tumble/bead-blast and then apply hand brushed finish...
just scrape it /s

good job adam
This might be PRODUCTION fast with EDM in mind won't have the cuping feature but it could be cheap enough to produce
