Awesome machine! I'm impressed with the single turret setup to say nothing about the fact that you jammed 2 turrets in there! Great work! Please keep us update on the progress.
Thanks! Hopefully the two turret idea works out -- I still have to write the code (working on it!) and find something that's like between 0 and 2 inches long that needs a hole in the middle that I can test!
you should definitely do coolant, you can use a small DC bildge pump for it which wouldn't use up much space and have a small fabricated coolant sump just under the machine, would be an awesome "micro edition" to your build and would be super easy to wire and plumb. I run mine of a small 24v power supply with the voltage adjuster turned down to around 17v. plenty of flow and pretty decent pressure. best of all it fits in your hand it's so small so the sump could be small as well, maybe like a 1 gallon or so. love the build, absolutely brilliant! keep up the great work!
I've used a little 12V bilge pump before for my milling machine and found it was almost too powerful. My main fear with flood coolant (or a heavy mist coolant for that matter) is moisture getting into the electronics area. You've intrigued me with the "micro edition" talk though. I may look into it more and see if I can come up with a "drip coolant" system :P. Thanks for following Christopher! Greg
hlaps1990 like know it's a little bit late, but down the road if you want to add some other really cool micro production features, you could use the shaft from a 5c spin indexer as the spindle and add a pneumatic collet closer. this would gain back a little z axis travel as well,. it's pre precision ground outside and inside and they can be had for around $40-50. just a brain teaser to ponder!
hlaps1990 ooh, and then if you wanted you could use a 5c lathe Chuck real quick for any parts that need facing that wouldn't fit in a standard 5c collet!
Funny you should say that, the very first rough spindle I made was a cut off 5C collet indexer shaft! The only issue is that it didnt leave much room for the bearings, but I'm playing with a design now for a 90mm spindle cartridge (which would require a new headstock) with an electric collet closer and a bar feeder. But first things first! I have to get this guy running soon!
Scrub to 8:50, look above the nut holder just to the right of the vertical lead screw. Sitting roughly horizontal with the head toward the lead screw. You can see it move around as you rotate the nut slightly.
man, i miss your content, if you still have the insert tool problem, justuse the aluminium inserts , the work for steel as well ,especially for shallow cutdrpths
Ah.. now i see, a second turret for axial tools.. Controlwise, i don't have any clue as to what you are using, my lathe and mill both run in EdingCNC. With that it is really easy to write the code for a toolchanger, and even writing parametric cycles is easy as well.. complete with dialogs to make a teach-in control.
Are these 1/8 HP Clearpath servos on the X and Z axis? Are they powerful enough? What is the ratio between the timing pulleys? I am building about the same size lathe and I am thinking about installing HC-PQ13 100W Mitsubishi servos. Used ones are pretty cheap on eBay.
The axis motors don't have any issues with the cuts, it's the spindle that gives a warning first. The reduction in the timing pulleys is only about 1:2 on Z and 2:3 on X (I forget exactly what they are). Most of the power in a cut comes from the spindle, and the axial and radial forces on the tool usually aren't that bad (I'm planning a video on this, so stay tuned!). To be on the safe side, the bigger the better :)
Did you use foundry to make the body of the lathe, if not, what did you use?Did you check any book to make calculus? How heavy is the lathe? Amazing job btw 👍🏼
Wow man this is amazing I have been a cnc machinist for only a short amount of time and have been trying to improve my self and make things beyond my imagination but holy cow dude your freaking awesome. I hope one day I can be able to sit down and design shit as good as this man.
Start taking cad/cam classes (assuming you're just operating the machines and not designing the parts.) Your work might even pay for it, or at least part of it, or maybe the books, etc. I'm a chemistry/materials sciences major, and my mentor told me to start taking those types of classes (computer programming, in general) because everything is going that direction. So I guess, no matter what your education/career path is, you should be doing something with computers.
thanks, love what you have done so far. Trying to decide if I should go a similar route and build a machine or just bite the bullet and order a new loaded TAIGTURN , I love the new 5C collet headstock they have and I already have a full set of 5C collets is 64ths :-). ready to go right out of the box is kinda nice..... just build an enclosure.
Nice! You may already know this, but Reprap 3d printers can use an sd card to run G-code without a computer attached. The RAMPS 1.4 boards are Arduino based and could provide step and direction signals to your servos. Very small and low energy.
I am thinking about getting a Taig. Can you sturdy them up and use a bigger motor? The XY on the mills and some lathes look really sturdy. I was thinking of a half to one HP 3-phase motor and a VFD. Have you considered buying some T-head Allen wrenches? :) You should likely tighten fasteners half as tight as it takes to strip the threads or break the bolt and not tight enough to plastically deform things. Or you could read the specs and use a torque wrench. :) You do NOT want one of those hardened cap screws to come loose and jam up the works. Probably 150+ psi tensile strength hard. Metric tends to be harder.
You can actually buy it at 1/2 hp, so it can handle that. I'd go for high RPM and hopefully low cutting forces. I always wanted to try one of those air cooled chinese spindles--the RPM range (5-20K) is about right for the Taig with carbide tooling. The X and Y are very sturdy, but the Z actually pivots at the back (that will be the first thing that gives), so I'd reinforce that first. I really should get some nice allen keys :P
What a great looking machine. Please do more videos on its construction. with more details on how you made it. Also, you say it's 1 HP, but isn't the Clearpath 3441 drive only 1/2 HP continuous (160oz-in x 3150RPM x 0.00074 = 373W = 0.5 HP)? Thanks and I can't wit for more on this spectacular lathe.
he has 1:2.5 gear ratio lol it output 1hp to spindle. i guess.dunno,but if it spin 7000 when servo only spins 3100,but it should make it worse.any way it cuts even hair thin is good xD
Sorry for the delayed reply Bence. I have heard of using raspberry pi and beaglebone black (machinekit) but it's just a bit over my head for programming:(. I think there's a lot of room for improvement in the low cost 32 bit CNC controllers--they certainly arent turnkey yet, but the future is bright!
@@TabletopMachineShop You won't need any programming skills. You can install Linux on the Rasp PI and use it just like a regular computer. Except it fits in the pocket of your shirt (or you can mount it on the machine itself).
Thanks! The issue with winding up with stuff is just space, but I've gotten creative with storage -- perhaps I'll do a video on my apartment that swallowed a shop one day!
Yeah, arduino is nice, but I'm just not good enough at electronics to get exactly what I want. I know arduino can run GRBL, which is a G code interpreter, apparently its at the absolute limit of the arduino's memory, so customization would be really hard! Masso purports to be exactly what I want, so hopefully that works out!
I'm watching your videos in order, and until this point I just *assumed* the second turret was a tailstock turret. You've got both on the carriage which kind of de-rails my tiny brain. No turning between centers? I has a sad. My lathe project is not as 'from scratch' as yours; I'm slowly replacing assemblies from an old Craftsman 6x18 lathe. The goal is to modernize from the bed up, its gonna take a while :)
Sorry I didn't reply sooner, this comment got put in the "awaiting approval" bin! how rude! Its funny you mention no tailstock; I figured it out about half way through the build too... it's actually a fairly major design flaw. If I don't have a tailstock, why are the rails so long?? Will I ever even be turning things using the whole length of the rails? Oh well, lessons learned. Any chance you're putting your lathe project up on RU-vid or IG? I'd love to follow along!
Based on your shooting related turning examples, my theory was that you made your lathe specifically to turn bullets and shells, and didn't need a tailstock. I know a fair number of manual micro-lathes are dedicated to that purpose. Regarding my project, the stuff I'm (very slowly) doing has already been covered well dozens of times. I'm not innovating anything, just executing ideas that people much more talented than me have already worked out. Should I ever manage to have an original twist on something, I"ll put it out in the world. None of my projects have any of that yet ;)
Why do I always hear skateboard bearings called "608" or "6008"? Which one is it? You could do "quick change turrets," and have a few turrets that you can swap in and out.
As far as I know, 8x22x7 bearings are called 608 (bearing trade number or something). I do believe you've read my mind with the quick change turret idea :P
Expensive :( . Assuming I got the design the way I wanted, it would probably come in around $7k-$10k.. I got a quote for one turret (qty 10) and it came in around $750 USD. Everything adds up so quickly!
Thanks for sharing.I hope after you have complete and perfected your magnificent machine you would share the total dollar(if it isn't much to ask about).Keep up the good.I envy your endeavor hlaps1990.
I actually got as far as making a live spindle before realizing that without any kind of brake or a direct drive spindle I can't use it. Ready fire aim!
Well what about some kind of a disc brake from or like a bike and maybe controlling it with a levered pneumatic cilinder? O.O Thats what i did on my lathe, although i just milled a clamp to go around a large diameter pulley attached to the spindle, and inserted a threaded rod to do the clamping and made a little lever on the side, manualy operated though :/ Heres a pic - www.image-share.com/ijpg-3480-70.html and never mind the christmas decorations, that was.... the gf -.-
a disc brake from a bike is a really good idea... fortunately the whole thing is modular enough that I could make a live-tooling compatible spindle cartridge if I had a mind to, so I'll jot down the idea of using a brake, even if I can just do radial drilling that would be cool. The original plan was timing pulleys and locking the spindle, but there's just enough play in the belt that it wouldnt work.
hlaps1990 yeah, i trusted the belts too much aswell. I think i saw a nifty jig that Atlas or Myford built for their lathes to incorporate precision dividing. they use an expandable collet that goes through the hole of the spindle, and locks the spindle to the worm geared dividing mechanism thats attached to the back. It would be an awesome thing to have on a lathe. You could do your own timing belt pulleys \(`°`)/
it just reminds me of the 500,000 dollar dmg mori's at work. en.dmgmori.com/products/machines/turning/horizontal-production-turning/nzx/nzx-2000 ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-XnetWfwonrQ.html
You REALLY need to get a girlfriend that's "into" what you do,or at least is understandable,or you'll be pussywhipped your whole life.....NOT a good thing.Took me 3 wife's to find one that gets what I do(did,I'm disabled now,but still tinker,and am a packrat),but I got a good one now and all is well.I wish the same for you.Your vids are entertaining,you gained a sub!
Im just kidding about her :p. Shes actually very supportive haha... shes let me commandeer large portions of the house for my hobbies. Thanks for subscribing Kirk!
