Hi folks, Robert come lately! I've found this particularly useful and am implementing something very similar on am Excel/Optimum BF30V mill - it has much more substantial castings than the standard BF30s. Ordered various components from the far east and everything arrived on or ahead of schedule and very well packed. I'm integrating it with the supports for a three axis DRO due to the positioning of some of my oil ports and my desire to have the read heads fixed so the cables do not move. One enhancement I've added is stainless steel coil spring protectors on the oil lines. However the brilliant idea of using purpose designed brass nipples has avoided the need to drill out the existing oil ports to take 1/8 inch NPT threads which was my original and somewhat concerning idea. The table on the mill is too heavy for me to safely manhandle without bringing the engine crane in from my garage, I'm too old now for that sort of thing!
Very nice vid! Two questions. Why grease on the ball nuts......mine is fed by the same oiler as all the ways. Are you having any issues with the one-shot leaking? Mine....and many others I've seen....have a really bad leaking problem.
McMaster sells all kinds of those push lock connectors. You could have gotten one with the correct thread to fit your manifolds that also had the correct tube size that you needed. They are also a lot nicer to work with than compression fittings.
Brilliant video's as always. I'm in the UK and in the process of converting a WMD25VB mill, which is made by the same company which makes the PM25, to CNC using Centroid Acorn which I used on my previous smaller mill. I'm pretty much mirroring your central lubrication system, but I'd just like to know how you did eventually route the grease tubing to the Y axis ball screw. Did you drill through the side of the base or arrive at another method?
Hi. I did drill through the base. I drilled and tapped a hole through the side of the base. Externally, I installed a grease fitting. Internally, I ran a short piece of tubing to the ball nut. Grease was pumped directly into the ball nut. It seemed to work well. Thanks.
Have you been able to push the machine yet? I'd like to see what kind of spindle load it can actually handle. At 4k it's still cheaper for me to make my own mill if these aren't "perfeft"
First off, thank you for all the videos, very good and informative. I just received the PM-25MV mill, the CNC conversion from AZ Video and have the mill pulled apart. My thinking is now is a good time to add the one-shot oiler upgrade. My only issue is I cannot make the M5 Press Adapters for the banjo connectors. (don’t have a lathe) Are there any alternatives for this part of the setup?
Hi. You can just drill and tap the existing holes. I made the press fit adapters because I was feeling fancy. Drilling and tapping the casing will work just fine.
I'll just drill and tap a m5 thread on the remaining brass. If that doesn't work well I will enlarge the hole and change it to 1/16 npt thread. McMaster Carr has the 1/16 npt to m5 bushing 1859N144 for this.
Hi Franco, again, great video! Curious if you have time / interest in making / selling a set of the bushings? I am in the process of converting a PM25 and do not have access to a lathe. I can probably make something worth with a drill press and file if not.
If you have a PM25 and some R8 collets and a vise, you have a lathe. You can clamp the cutting tools in the vise and the work in the spindle, and use the mill as a light-duty lathe.
I was wondering what size was the hole in the PM-25 casting for the oilers? I measured the ones on my PM-30 and the oilers are 6mm in diameter. Trying to find a push to connect fitting to use with these holes. I was thinking 1/4-20 NPT .

Awesome video Franco. You did an awesome job and produced another great video. Thank you for sharing.
Very nice work. I am in the process of doing this to my G0704 and I really appreciated your screen caps and details review.
Thanks - I'm glad you found it helpful.
awesome video. planning to do this soon on my PM-30MV i just got.

Very informative Franko 👍

Good point - I'll probably do that.

@@FrancoCNC Thank you Franco for such a quick reply, I'll now do the same.
Absolutely Useful Video !
Did you drill and tap the ball nuts for the push connector?
Great video. Out of curiosity, what oil are you using and what grease for the ball nuts??
nice video ! but were are the links to buy this parts ??

were did yoiu get the cdheck valves?

6mm I made these things to adapt to M5: a360.co/3dbzMED
why not oil your ballscrews? that's what all the pro's do
