Simple conversion of a mini lathe into CNC
Vložit

- I show how to convert a conventional mini lathe (sold under various names such as Sieg, Grizzly, Aximinster...) into CNC. A first step - a workable lathe with limitations to be improved.

Did you once serve on the uss Enterprise 😉
very well made and clear video. please make more!
Thanks!
Отличная работа! Мне нравится, как вы говорите на английском, я все понимаю, а других зарубежных смотрю, много не понятно
Понятно потому что по русски)
Nice job sir
Great job. Thanks for posting.
Thanks. Yet, it needs quite a few improvements...
Great video, very useful for my planned conversion. Do you think it is worth adding a gear reduction system for increased torque? I'm thinking about using a belt and some pulleys.
Thanks James. Everything is possible, but I have not found torque a major problem. I would love to have a lower speed and higher torque, but it is easier to focus on what we have. Making noisy gears to me a bit too much effort for little output. What I want is a good rotation speed indicator (with 1/100 turn readings) and computer-controlled speed
I dont think having the ballscrew offset on the X axis is helping accuracy very much. Id prefer to go for a smaller ballscrew mayber 10mm or even 8mm and run it through where the original leadscrew was.
Your mounts also dont look very rigid at all. You need solid couplers and I think a better option for mounts would be thicker aluminium plates supported by 4 pillars. All this could be made on the lathe fairly easily without the needs for an external supplier.
You may be right. I did put 12mm ball screw later and it got better.
Yet, it is possible to put it beside, but you require a hugely more rigid connector.
Great video. But I think it would be easier if I just send you money and ship one to me, or fly here and build me one 😁
I would love to, but I am barely able to keep up with the other interests... It is surprising, why the Chinese do not do reasonably-priced CNC lathes....
What software do you use to draw and generate gcode?
Mach 3 to start with; then Fusion 360. And it took forever to understand how to use Fusion for G-code. Possibly, I shall make a video on this at some point...
@@is_it_science Yea, that would be awesome to see how Fusion gets gcode saved. I'm all new to this, and using UCCNC software instead of Mach3 and vcarve pro for generating gcode, Fusion 360 looks very hard.
Полмиллиметра это как то уж очень многовато. Наверное эти тонкие нежесткие кронштейны надо выкидывать? Ну или как то их большего сечения вырезать?
Или поправок после контрольной проточки и измерений на паузе после неё хватит для нормальной точности? Только тогда код надо параметрический для машининга писать-генерить.
There are a few problems with rigidity for sure. Precision for soft materials is tolerable, but not for stainless...

What size stepper motor you fit?
Nema 24, 5A motors. I am not sure if it is an overkill or not
Hello, would it be possible to get the drawings for it?
Thanks - I shared it but forgot to publish! Here it is drive.google.com/drive/folders/1tP2AdmLGwleweIU_Jka51ePjiDQ_FDx8?usp=sharing
Бро, расслабься и говори на родном
Which software are you using for send commands???
Mach3. I suggest looking into Centroid acorn. That one could do real-time control and is much better supported than Mach3
