Glad I found you.. Doing a PM30 here using the Procut ballscrew kit. A few videos out there, yours is very digestable w/o a lot of excess commentary. Thanks!
Hi Thanks for sharing your work, the video is fantastic, informative and concise. The video is titled part 2, I can't find the first video, has it now been removed from UA-cam? I'm investigating a conversion on a Warco WM14 mill so keen to follow your process to adjust for the Warco.
Nice to see, we did a 4 axis CNC build off of a TAIG and it runs well but we love tool changers because changing to tools in the holders after each program cycle per tool is well tough, we are spoiled. Lance & Patrick.
I hope to do something similar for my milling machine. Very nice straight forward steps here. I know mine wont be exactly the same as yours but its good for a guide.
I guess need to install some dempher for Z-axis to compensate weight milling machine head, something like gas-lift, on the video during Z-axis moving down the ball-shaft did few rotations after motor stopped.
Those bearings are not seeing any lateral forces, so no need to have a press fit. Sure it would be by-the-book, but doesn't affect the end result here.
Where is part 1? Went to your channel and only one other video, that’s not part 1. Would love to see the first video as well as a new video showing the conversion in action. Regardless, Well done.
I have a question. I currently have an X2 Cnc conversion mill with Nema 23 motors using a 1/4" shaft. Can I switch my motors over the the PM 25mv cnc conversion , but I would just need to get the 1/4" coupler ends to fit onto my Motor shafts correct? I believe the Ball nut screws have a 3/8" for XY and 1/2" for z, but COuldn't I just get the coupled end for the motors to fit the motors shaft correct?
What's the point of using angular contact bearings for the X axis ballscrew if you only have one side? This means the motor's bearings are supporting the other side, which is one of the main reasons bearings are used in the first place.
Instead of doing the conversion, is it possible to just buy spare parts of PM machine that are required and build/buy the update. That route would be cheapest.
I own exactly the same manual milling machine, I am looking for advice on how to motorize the x axis. May I use the same hardware? Should I use the same hardware, considering that I don't need the reproducibility of a CNC machine? Thanks
manual mills come stock with ACME threaded lead screws, instead of the ball screws that he installed. ACME is fine for manual machines, but has too much backlash for a CNC machine. Ball screws eliminate most of backlash by using ball bearings to interface between the lead screw and the ball nut, www.barnesballscrew.com/images/1.jpg which is attached to the slide/head/saddle.
Thanks Joel. I sell the entire conversion kit except the stepper motors and controller. This kit requires two NEMA23 stepper motors (X and Y axis) and one NEMA34 stepper motor (Z axis). You can learn more about this kit at www.cncelements.com .
I would buy the highest torque one you can afford. AutomationTechnologiesInc.com has lots of options at great prices (no affiliation). They also sell motor drivers and everything else you might need.
Generally not, as long as you use high durometer urethane spiders. Fadal uses these style of couplers successfully. The couplers do wear out over time and need to be replaced. The alternative is to use a bellows style coupler, they are made of metal.
Very interested in your question, i have just bought a WM18 which is the PM 727 equivalent. I am currently planning cnc conversion. I have the steppers and most of the electronics. I failed to find any help with CNC conversions except at huge cost so will use my old X2 cnc mill to machine the parts. John
@@john2478 Hi John, out of interest why CNC the mill if you already have the X2? Also did you see the Model Engineer magazine WM18 conversion? Its only an overview and gives little detail on how to do it or costs, but its a nice approach, even features a second high speed spindle. One approach I have seen is to buy a second table and machine away the necessary clearance for the ballscrew housing, that way you dont invalidate your warranty and you can use the manual mill to make the mods. Thats what I would have to do as I do not have second mill sadly. It does seem to be an expensive process no matter what.
My X2 conversion was sucessful and has been in regular use for. 10 years. However I wanted a more substantial machine with a stiffer column to take deeper cuts. If you want to share ideas you can pm me on my channel after subscribing. I like many of Josephs ideas and will incorporate them. John
No because they are not ball screws, they will have too much backlash. The ball screws effectively have negligible amounts due to them running in circular channels which you can actually on the better ones pre-load to tighten the nut up against the screw.
Since there is a pair or opposite angular contact bearing in the left side the ballscrew can't move, so it seems it's not needed in the right side. Same when you use BF12 mounting blocks, on side is only for alignment. The motor does exactly that. Neat design I would say
This is not how you preload bearings. With this bearing configuration you need precisely machined distancer between inner races of both bearings. Problem is How you will measure the exact distance between the inner races when they are all ready mounted.
Sure you can do it this way, but it isn't the perfect solution. As for measuring the inner distance, there is no need to measure the inner distance if you know how much preload you want on the bearings, as you can look it from the bearing preload chart or measure the needed gap if data is not available.
Подшипники не те! Нужно радиально-упорные, а не эти. И все детали из стали, а не дюраль. Иначе будет низкая прочность. И не вижу системы смазки швп и направляющих. Без смазки чпу фрезер долго не проживет. А где концевые датчики на ось x и y? На z концевик недоразумение. Умрет быстро. Нужен индукционный, а не такой.

This is great. You make it look easy. Do you sell these kits? What PM mill do you use?
Thanks,

Nice… the parts that you build for this project (mount brackets for example) are made in aluminum??? Regards
Will you be posting a build job using this new CNC?
I’m hoping to kinda mimic this with my cheap wen mini mill
Nós dó canal ferreira motos estamos acompanhando tudo, 🇧🇷🇧🇷🇧🇷🇧🇷🇧🇷👍👍👍👍👍👍
Thank you
the paaaain @2:04 :P btw nice job
Very very good 👍👍👍
Do you have the plans or files to download and build?
The link to buy the kit seems to not work. I get "403 Forbidden".
Do you have any kits or plans available for purchase?
Why does the lead screw need to be replaced? To get rid of backlash?
Yes
I'm not allowed to go to your website. Is it still in service?
It's a very nice conversion.
You should have milled flats on the ballscrew before you dismantled the mill. That way you could use a backup wrench to tighten the jam but.
Very neat work brother but I think your bearings are way too loose (5:37). You need some press fit, just enough to tap bearings in.
Those bearings are not seeing any lateral forces, so no need to have a press fit. Sure it would be by-the-book, but doesn't affect the end result here.
awesome video great info.

Parabéns !!! que legal
do you machine these kits yourself?
great video
What's the point of using angular contact bearings for the X axis ballscrew if you only have one side? This means the motor's bearings are supporting the other side, which is one of the main reasons bearings are used in the first place.
Removes axial play from the screw. Doing both ends would overdefine the assembly and lead to problems with thermal expansion.
Instead of doing the conversion, is it possible to just buy spare parts of PM machine that are required and build/buy the update. That route would be cheapest.
I own exactly the same manual milling machine, I am looking for advice on how to motorize the x axis. May I use the same hardware? Should I use the same hardware, considering that I don't need the reproducibility of a CNC machine? Thanks

How confirm the alignment of lead screw position when consider the tough connection? thanks.
I don't see parts 1 or 3?
Did he die and we don’t know?
Nope, single video is whole series. Title is wrong,or maybe he decided to split the videos but he didn't.
How much it's the total cost for this conversion??

@@cncelements1987 do you have the link for nema23 and 34 since they all have different oz force which I not good at picking correct stepper.
I would buy the highest torque one you can afford. AutomationTechnologiesInc.com has lots of options at great prices (no affiliation). They also sell motor drivers and everything else you might need.
Very cool are your kits using single or double ball screws? Are you located in the United States? Where is part 1 of the video?
This kit uses single ballnuts. These kits ship from Florida. Part 1 should be coming soon.
Kolay gelsin 🇹🇷🤝
Which steppers are you using?
Won't the love joy coupling add backlash error?
Generally not, as long as you use high durometer urethane spiders. Fadal uses these style of couplers successfully. The couplers do wear out over time and need to be replaced. The alternative is to use a bellows style coupler, they are made of metal.

That's what I'm talking about!
wouldn't it be both cheaper and easyer to use the pre-existing lead screws?
No because they are not ball screws, they will have too much backlash. The ball screws effectively have negligible amounts due to them running in circular channels which you can actually on the better ones pre-load to tighten the nut up against the screw.
MORE! MORE! MORE!
Are you still in business ?
check their links. they are still up
👌👏🙌
at 330 shouldnt you be using a thrust bearing ?
Angular contact ball bearings are designed to take both axial and radial thrust loads, so a separate thrust bearing is not required.
hi , why you did not use a bearing in the motor side of the x axis?
Since there is a pair or opposite angular contact bearing in the left side the ballscrew can't move, so it seems it's not needed in the right side. Same when you use BF12 mounting blocks, on side is only for alignment. The motor does exactly that. Neat design I would say
