I just ordered one and am looking forward to installing it!

What did you do about lubrication? Did you change out the ball oilers with a one shot system?

That poor drill...

Great video. Before watching, I fumbled around for an hour. After I watched it, I was done in 20 min on the first try. Thanks for sharing so many of your tips and tricks!

Great video content! We at Halnn Group are also committed to providing high-quality cutting tools

I really want to get back to the project. I have had a record amount of kit sales early this year, it has slowed down so I hope to get back to the fill soon. I have to do the spindle belt drive for the PM-940 first but I have done them before. Thanks for watching

really hope to see part 2 of this build soon! great work

I bought a couple of 16mm mills for APxx 11 inserts, and a couple boxes of APKT11T308, one for aluminium and one for steel to be used with my DIY CNC (yet to be finished). I'm working as a lathe machinist on a Mori Seiki NL2500 with live tooling, and I decided to try on carbon steel (C45) to see how it goes. And it goes well. I had a couple of parts cut too long to machine, so I tried to remove that material with the less than 20€ mill, and it worked ok. It has a little runout (0.07mm) between the two inserts, as every insert mill isn't a smooth cutting tool, but it works. After milling out something around 1.5kg of C45 the inserts are like new. Not bad at all.

Just found your channel and subscribed. Very nice work

Great info for when I start working on my PM 940 V

How much does it cost?

Amazing huge thanks

Are any of the kits shipping? What is your website url ?

Does this kit fit on a hbm profi 45?

Which one will produce better face mills on aluminum, PM-932V or PM-728VT on a CNC setup? Thanks

how to contact? was interested in a kit, tried emailing but never heard back.

Isn't there a risk that the drilling and tapping of the base distort the casting ? I'm not a metallurgy expert, but from my understanding, unless the casting was stress relieved, removing metal can cause distortions. I guess the a compromise is needed between maximising added stiffness (lots of of tapped rebar), and minimising metal removal from the casting (less rebar).

Weiss 20V ?

I'm impressed all around. With the Chinese insert mill (and suspect quality inserts), the mill, and conversion. Is that the APMT/APKT cutter? Well done.

Massive thankyou. Helped me resolve my problem. A good thing to know.

Hello Im interested in the PM30 kit. I was wondering what the lead time this kit is ? Thx

hi, do you make a ball screw kit for a shopmaster Eldorado bridge mill?

I watched 10 video to see how to install plastic seal no one did that

So I was looking at your website and don’t see the PM-932mv listed? Was this removed or out of stock?

Will this kit also fit a hbm bf 30 mill?

I have a pair of SFU1204s and followed your video on repacking. I noticed the bearing in mine keeps binding at the orange bearing recycling cap thing. The bearings keep stumbling over each other in that area. Does that happen to you?

great builds.

could you please post the O.D. of your plastic ball bearing retaining tube? My nuts came pre-installed on the ball screw and I need to fab a tube to re-install the ball nut.

Thanks for this. I purchased a kit from heavy metal cnc and the acme nut on my z axis is installed opposite end of standard🤷‍♂️. Per the z axis assembly diagram. I looked at dr d Flo’s conversion video and his was also opposite mine. Bruce didn’t do anything wrong, that’s china for you….. bad assembly. I had to remove , repack and reinstall mine. Thanks great video!

Built my own. All double ball nuts, 30mm z rails, 25mmX/Y & 25mm X/Y ball screws and a 40mm Z screw, machined my casting on a 4020 down to .0002. 750w X/y axis servos, 2.2kw Z servo with a brake, HAAS 5c 4th axis converted to servo and a bunch of other goodies. 2000IPm rapids bolted to floor and 300ipm cutting is not impossible. It has 14.5 x 28 table travel. Very broad swing and something the stock manual could never achieve. Mine is now the Nicest PM833T in existence. Most likely will always be at this point since you’d need an industrial machine to do the same build. FYI for anyone considering linear rails they will not just drop on a factory casting and anyone converting there’s to linear rails better be machining the castings first. The PM833T manual was a pile of crap put of crate and wore out those ways in under a 18 months. Yes, I oiled it daily. I bought one of the very first machines they sold. They were definitely not hardened. Frankly PM screwed me over and they should’ve replaced my machine free of charge. Terrible customer service. Now that i know how to cast myself and also where to buy solid castings ready for linear rails for only $1500 a complete machine, id never buy another Precision Mathews product again. So many parts needed to be warrantied and a few already had been where I had finally gave up on it. I also got rid of the gearbox it was limited and noisy anyways. Went to a belt drive and never looked back. Made and machined every part on it myself. The Spindle spins at 12000+ rpm now. The motor was custom built and handles 200hz easily sending it to 7700rpm itself. I started machining a bt30 out of 4140. Let it sit to relax and destress before i get to the finish cutting. It is ready now. Journals also need to be hardened. I can do that with my induction heater. Anyone considering one of their machines consider how they left me and others stuck in the mud before you buy. Ive owned many brands and the only advantage they have is travel. Wish you best of luck.

At this point I would’ve just cast the entire lower in one piece so you could have a larger 16-20” Y axis. The shallow black poly home depot storage bins are perfect for a really nice base. The form adds some external bridging to the cast which looks good. You’d need a second for a stand below it and you could easily epoxy them together into one piece.

I'm going to do a second test fit with the customer's 833 soon. I plan on doing a little video too so I will look at the ways closer. I looked at them before and they looked like they were ground with oil scrapes which is what I expect. The felt really nice even when tight. A good grind job is fine for a hobby mill. I think a common problem is some go too fast and heat up the work and they bow. A little extra care when grinding goes a long way.

Aren't the 833 mills supposed to be hand scrapped?

Looking forward to this

This is great. How much and are they ready to ship?

Looks good. I'll be looking into that when I move up to a larger mill.

And the cost is?

CNCspeaker is me too. hopefully tomorrow will be the final fit test of the 833 kit and it will be ready to go out after that.

Testing the last part today for fitment. Should go well. Will post pictures of the full kit soon after. It looks like the Z can be flipped so that allows for the larger Z ball screws of D=32mm to work.

Why is the z column bellos not installed.

What's a sign that your ball screw needs to be repacked?

Just went looking for heavy metal cnc 💩

I really need to change my IH to belt drive.

Do you have a X & Y axis ballscrews for a G0761 mill , I just want to use by hand the left side has a power feed the Y has a hand wheel

Any progress on this?

I’m curious, I have a manual PM-932 (non CNC) mill and I was wondering if I too can gain travel by cutting this section of material out to gain Y-axis travel? Is this section of the casting preventing the saddle from moving further towards the operator ?

Play that funky music white boy! I remember hearing that when it first came out and jamming out with my brother. 🕺

Sorry but I cant sell the drawings. Thanks anyhow. Dave

Thanks for posting this.

Hi. I have a weiss vm32l that Im looking to convert. Hoping to use closed loop 5nm torque nema 24. Trouble is I live in the UK. I already have the ball screws. Do you sell the dxf / cad files for the plates or only the finished milled product. Trying to keep cost to a minimum atm. Thanks
