How it's Made: A really small lathe automatic tool changer!

Subscribe and follow on instagram to keep up with the build!

This is my first actual Youtube video! In it, I show how my first attempt at a tool changer for my lathe project goes together! I still don't know what to film about my lathe project, but I know that I like seeing how things are put together (though I'm a sucker for machining videos as well!) I have two new tool turrets that are almost done that I'll make videos on, and then eventually the actual lathe will get a series of videos. Subscribe or follow me on instagram!

I really miss updates on this project. Hope you are doing ok in this tough times, and hope you and your loved ones are healthy!

Ratchet is not enough - there must be a Hirth coupling.

Nice job. But since the indexing motor is a stepper, there is no feedback of the indexed position. How do you ensure there is wrong or no indexing due to some problem and the right tool is in to the position.

Got any drawings or plans for these? I have a small lathe ive converted to CNC and something like this would be ideal for it.

Very good video Sir
Can you plz deeply describe the electrnical part of tool changer with mach3 board and mach3 calibration

[pypes]

That's probably the simplest ATC I've ever seen. Well done mate

You do good work and I understand why your company would allow you to do your own projects; I can tell that you learned a lot about design and construction of a somewhat advanced tool and your company will be getting a better employee in exchange for a little tool time.

I'm going to subscribe for and I hope you use the lathe to make more tools.

Nice job sir.
What you really needed between the stepper and the shaft was an 'Oldham coupling'.
They are a really nice way of isolating two shafts that are not completely concentric.
I can't readily explain how they work here, but just google 'Oldham coupling', and you will see what I mean.

Outstanding, one of the best projects i've seen... Keep up the good stuff !

I randomly stumbled across this video. Very well thought out mechanism. I see this is an older video, and am looking forward to seeing how this project matures. Subscribed

What a beautiful tool changer!!! The pawl even makes official sounding clicks.

[joecnc]

I hope that you put together a drawing or sketch package on this. someday.

[tonymasse]

Freaking awesome!
I like the design, even without any flexible coupling, as it won't rotate that much.

You are driving the stepper with that little chip? If so, that may be why it got hot. You need some kind of motor driver I'd think. Great build!

[hyperhektor]

any Progress? looks like very interesting concept


7:13 its a arduino pro mini since it has no usb, the nano is simila size but with usb and 25-40% more "expensive" (3$ :D), seller throw in nano in some auctions to confuse the new buyers to overpay the product.

Only a minute in and an SKF Speedi Sleeve would have been my first thought. I'll watch remainder to see your solution. Normally wouldn't comment early but planning to remember something doesn't always survive the distractions. You have enough room to put an internal coupling fixed to the motor shaft and allow for any misalignment problems. You know a lot more about electronics than you give yourself credit for. Just let your needs show you what to learn next, it can be better than filling your brain and having to look through it in an industry driven by new things. All the best, thanks for sharing.

Very nice, great work!
Regarding your concerns of tool location at 7:40, could you not code the stepper to reverse rotate slightly so it seats the ratchet?

One minor change I humbly suggest for version 2 is the addition of an encoder so your computer can determine which position is currently selected. An optical encoder should work but might have problems with cutting fluids/coolant. A magnet based encoder would be very reliable though

Cool project... i have BL20L manual lathe and i interested to convert it to CNC...

[protoserge]

I look forward to watching more. Thanks for the great overview!
