Your videos are amazing! The subtle humor is really nice. Thanks for balancing out the crap on RUclips
Yeah really
Dry as toast German Humor is my favorite!
I loved the Valve reference! I imagined seeing a red valve.
Contamination is an issue on unprotected CNC ways. When I was making my CNC, I found that the best grease to use is: often--meaning an vicious cycle of cleaning and lubricating. On the ballscrews, I used oil. Once I get settled, I am going to make some wipers.
I documented the whole thing on my channel.
Cool channel! I am off, trying to find a harmonic drive motor :)
@@reps, Thank you : )
Harmonic drives are amazing devices. I put a laser on one, and had it turn. At about 4 meters, the steps were so small the beam connected where it was. I am lucky enough to have some--that were being scrapped!
I wrote an Arduino stepper utility called RDL for testing motors. It's linked from my videos.
Thanks for sharing you projects.
On an 80's era CNC mill they used a one shot lubrication system. A clock motor slowly raised a spring loaded pistion that slowly filled with oil. Fully primed it was like a pinball being released. Several seconds were needed for the pistion spring to overcome the many small restricting orifices that regulated the oil distribution. Sort of an oil artery with a very slow heat beat.
whaaat? double upload? I CAN'T BELIEVE THIS! this made my day so much, I love your videos!!! amazing work!
I thought it was Christmas or something. Double Marco is a once in a blue moon event!
Hmm seems too good to be true, probably just dreaming rn
Double Marco all the way! What does this mean? OMG 😥 😂 😭
Somehow you make industrial oil mildly pornographic. I'm amazed and disturbed at the same time.
mildly?
@@reps highly.
Extremly

i see your a man of culture as well.
Ah yes

And I see you’re a fox of culture
you're*
It was weirdly sexual
progressive *Valve* ...
I see what you did there ;)
I'll always stick around to hear you talk about lube
Pour angling the container to the opposite side! A trick I learned working at a laboratory in the oil refining industry.
wtf does that mean, do you have a diagram?
@@ihatenumberinemail sorry for my English. I mean that he should tilt it towards the opposite side of the outlet.
Pro CNC machines use a Bijur (or similar) lubrication pump that runs at an interval of around 18 minutes. It lifts a piston and at 18min the cam rolls over and the piston is driven down by spring pressure. This feeds a line that goes to 1 or more manifolds with metering units. Old systems use unsophisticated metering units, newer systems use delivery valves. This method has worked for a very long time and it reliable as long as you use good oil. Some makers use central grease systems for the ways and spindles, the have a grease pot that is either a urea driven pump or mechanical pump. I believe Brother is one of the MTBs that uses a central grease system, Hardinge used a central grease system on their somewhat older VMC mills.
My brother speedio and my robodrill are grease machines. The speedio is automatic grease. one nice advantage of grease is you dont get tramp oil in your coolant.
Everyone caught the Valve sound but NOBODY caught his Half Life 3 reference?! HL3 confirmed!
"It's a progressive Valve" ... "whi-whi-which all receive..."
This video is extremely cool!
Many of the Hass machines in my college shop have an automated system which pushes specialized “grease” into the linear rails using compressed air. I say “grease” because I don’t actually know how viscous it is.
The old trusty manual lathes and mills use manual oil lubrication and it works fantastic
Hi there, just wanted to Share with you that i worked around professional machining centers e they all have that kind of lubrication system.. but yours Will work, by far, much better then the ones on the machines i know... Only because they have the filosofy of only fixing when they break ☹️.. anyway i like your videos very much
Dude, you're making a mess! But I'm cracking up watching it!
I have tried to clean thoroughly, but everything still smells like crude oil in here ... me included
@@reps Try not to smoke there.
@@MCsCreations Oil is flammable, not explosive.
@@rich1051414 Thanks for ruining a joke.
Not boring at all, this is extremely useful and interesting information. Thanks a lot from Australia!
Underrated channel! Dry topics sweetened up with even more dry humor. Always a pleasure to follow your journeys into the undiscovered worlds of diverse high-tech
I found your channel by searching Keithley Instrument fixes. While 5.5 reliable digits is what I want, this video is pertinent. Very pertinent. Thank you.
6:50 omg don't do that! That sound hit me right in the feels...
whiwhiwhich :D
@@4lxAnd3r the valve one, reminds me of playing Portal...
Maximum mess in every shot was a nice touch. I know the anxiety of avoiding spill and cleaning every drop as you go so it’s nice to see the opposite for comedic value.
Double upload?? I’m not crying you are
"The manufacture of my BALL..., Screws"
These innuendos and the way you phrased everything in the beginning was epic.
WOW! thanks for the lesson on lubrication, very impressive.
the moment when Marco Reps is uploading a new Video... amazing
6:55 the voice delayed reference ( NICE! )
I'm a professional cnc operator and the Haas mills we have use "Haas liquid grease" for the X, Y and Z slides (I think they wanted grease but for the central lubrication system they needed a middle ground) and some kind of oil for the 12000rpm spindle.
Hi there! I was working as an professional tool maker until last year in CNC for nearly 20yrs. we used glp68 (mannol or simmilar) or even hlp 68 as an alternative for lubrication. price is 30€ roughly for hlp for 25 Liters. You dont need much for a mashine like this. Would last maybe years if not even longer. These oils are industrial standard for cnc machinery. Good luck with your project. If you want some more knowlage about cnc, just ask me. Greetings SAM.
See you soon? That was pretty soon.
Zwei Repsens für den Abend von einem, brillanter Einfall!
Dude, some of the stuff you do just makes me cringe and laugh and get nervous, but more than that, I love your editing style with random clips and thoughts and i end up learning a lot. This is exactly what I am looking for.
The gravity of the situation is such that lower viscosity lubricant is advantageous considering initial tolerances, cycle life and ease of distribution. Metered gravity reservoirs dedicated to each lubrication point are simple to maintain and require minimal maintenance. A simple solenoid actuated valve administered to each lubrication point or subpoints. Independent signal agregation from each axis via controller provides flexibility for optimization and tuning.
As a michinst/repairman, this was a valuable video. Thanks for sharing.
Man, this valve block is the thing of beauty!
I used NGLI 0 grease instead on a remote lubrication system. Pumps fine through 3mm tubing, and is a very good lubricant, though you do run into the excess grease problem, though as that machine used a mix of roller, ball and slide bearings you do have to be careful in the amounts you put in each section. No automatic lubricator but instead just all the lubricant lines brought to a central block, one side of which was threaded for M6 push in fittings, and the other side was 1/4BSP to fit the array of low cost grease nipples that made up the face. The grease would pump easily through the lines, and the excess in most cases was easy to handle, though there were some places deep in the bowels of the machine that you simply cleaned with "the dirty vacuum". An old Columbus cylinder vacuum that had a long suction hose, a few modified crevice tools, and regular cleaning of the hose outside and inside, cylinder and bag with first engine degreaser then regular industrial detergent. cleaning as part of the monthly maintenance cycle worked well here, you never got the great big gobs of grease that I had to chisel out the first time I had to scrape out the bowels of the machine during overhaul.
A better quality system will pump NLGI2 greases
Better quality distribution valves are adjustable
this is amazing, I was actually right in the middle of putting together a lube system for the CNC router I'm building. I don't have the fancy gear, just a Chinese hand powered one shot oiler and some needle valves to tune later.
Get SKF System 24 bottles if you can get your hands on with decent price and forget those needle systems.
2 Videos at the same time ? In the middle of the Night ? Awesome !!
Most modern machines are running grease for the ways now. High precision machines have been running grease for decades now. The bad thing about oil is if you run flood coolant, it's going to contaminate the coolant.
Hello, professional machines use pressure relief valve manifolds which dose single and precise amount per each pumping cycle. That way you can easily control dosing by software. They are also much simpler in build and very reliable thus having less moving parts and they are also cheaper. You can even buy pressure relief valves separately and make simple manifold out of aluminium bar.
The props in this video are brilliant.
So glad to see another CNC update! Thanks, Marco!
3:20 I think it's exactly where it's needed. Nothing better than an oiled up, naked... CNC machine.
7:19 - Wow... never knew it was that complicated to distribute fluid/oil on a metering/manifold block.
Automated lubrication is cool and good. However my current recommendation is SKF System 24. I can't recommend it enough. Grease or oil in see-thru cartridge where you manually set months to discharge. Absolutely beautiful little things. Been using one's for years and they're incredibly accurate and easy to setup. One of the beauties of it is that there's very minor continuous flow in hard conditions, say if machines are washed daily etc. They're also incredibly easy to retrofit on places needed. This comes from packaging machine mechanic.
yeah that looks pretty great indeed! I had no idea that that exists.
Swiss made Simalubes are a market leader in disposable single point lubrication
@@mrbumcraic5046 Yeah, I've heard about them. For me SKF's were cheaper and I frankly didn't have any reason to move. System 24 has never once failed on me and they're accurate.
jothain
the first system 24’s were rebranded Simalubes
Simalube also have a custom fill option so you can use whatever grease (or oil) you like
@@mrbumcraic5046 Yeah, I know about that. Still for my applications I'm totally fine with ready greases so I don't have any needs for fillable systems. On the contrary it's more convenient to not waste time on something like that. Though I fully agree that it's nice that there are options for customized applications if needed, I've kept that in mind.
That valve configuration reminds me of a dc to ac inverter.
What was that model you drowned in oil? Looks like something i would like to print
Double Marco-fest! Yay!
Why do I suspect he came back to his PC to upload this one, and discovered an "upload failed" from last week for the resin printer ;-)
A good oil based pump would be found in small industrial machinery, and whilst you couldn't buy those without magical leg and hand loss, you can find them at scrappers and refurbish them. The ratings are above any CNC lube requirements too, after all, they are meant to lift tons AND they are small, some fitting in the palm of your hand (-motor).
3:30 I'm not sure why, but that was really hot.
aaaand DEMONetized
Haha I just got the valve sound 🤣 that's why I watch all your videos at least three to four times
I like the resin woman that you poured oil over
The other end of the lubrification spectrum was quite interesting.
correct me if im wrong but hass acually uses grease. and the oil pump is for the spindle
It's a pogressive VALVe.....
VALVe theme starts in the background....
Perfect reference 10/10
More interesting than I think you would have given it credit for.
That's an exquisite capacitor indeed.
You confuse me, man, making me feel all smart and curious and in awe and humble and stupid, and small and all sorts of fella all at the same time.
anyone else finding these vids super relaxing?
Have u tried with oil metering units? They are made to send the right amount of oil where u need it, even if you have N lube points, is a clever design. Take a look at bijur.
Haas machines use a grease, but a relatively thin one at that
Hey, nice and informative video, does thermal expansion of the oil cause any issues? And are you planning on collecting oil back into the tank and recirculating it, something like with cooling fluid?
Phew ... I have not seen any problems with thermal expansion yet and I'd expect my pneumatic push-in connectors to pop long before anything expensive ... but good idea, I'll keep an eye out. At the moment I am aiming at a minimum quantity lubrication with 2mm³ per 'consumer' per cycle. I was hoping that such a small amount of oil will somehow dematerialize before ever reaching the floor. But the more I think about it, the less likely that gets... I may have to add some sort oil pan. But no recirculation for now.
@@reps Just add a rubber oil bellow to the tank, if it's not already present. That solves all the thermal expansion issues. If pressure builds up in the consumer/distribution side, the valves will just run a 1/8th of a cycle or something like that, so there isn't really a place where excess pressure can build up.
Great vid dude. I learn so much from your stuff. Thanks
Those valves barely ever screw up, you can get away with using push air fittings as there isn't much pressure in those, its more a little trickle constantly, these are over kill for your use, we used these at work on m/c's that were rotating at a few thousand rpm on bearings that are 12"+ and rails that are doing upto 300 strokes a min, in between the pump and blocks we had hydraulic spring loaded reservoirs/similar to a timed shut off valve while it charged, the pump was then on an open pressure regulated loop back to main res, this helps limit the amount of oil wasted. Just so you know those blocks come in different ratings so you can limit/increase the flow as needed. What oil hits the block is wasted if you have coolant cutting fluid as well so you will really need to limit the amount of time, like pump runs 2-3 mins over 30-60 mins run time.
When I saw that pump I knew you'd been spending some dosh. Those are commonly used for those platform cargo lifters on trucks, and they cost like €1600, locally to me anyway.
Dude can't wait to see that beefcake cut hardened steel. Lol but for real should be one kick-ass machine that lasts for ever the way your building it
6:50 I thought my PC started CS by itself. Nice one
nice links and all but I missed where you got that ground ballscrews?
Lincoln / Masytec does central lubrication, perhaps you can find more reasonable priced central lubricators from them...
DOUBLE VIDEO? Oh yes, how exquisite...
Very ingenious valve, it's amazing how much logic an apparently simple steel block can put into the world. And that under heavy load conditions.
However, where do you get the money for so many toys? I want 20 liters of a random mineral oil, too!
So close! I don’t have the patience or knowledge to do a DIY CNC machine.
Knowledge is not a problem, just film what you do and put it on youtube, some wise-asses will come and correct things for you :)
Hey Marco, I really like your videos, keep 'em coming buddy, they are highly entertaining, informative, interesting and worth learning from.
Thanks for the Vollgas/Full Throttle flashback at 6:50 ;) great video btw. Thats quite some "hobby machine"
From the look of the scheme it defiantly can recover from starting with random piston positions. It will skip several outputs through the first cycle, but thats it.
Can you tell just from looking at that? I would have to sit down, put my thinking cap on and focus for half an hour to make that call :)
@@reps Yep, I am pretty good with that sort of things. It is arranged in such a way that fluid shifting piston from side A to side B opens up channels that allows same fluid to shift next piston same way, with the last piece of the stack shifting the first one the opposite way. If pistons sit in random order it will start cycle by shifting the whole stack to the side first piston started at, with pistons starting on that side already sitting with necessary channels opened. The only thing I am not 100% sure about is how it will handle every single piston sitting smack in the middle.
Plus it would be virtually impossible to transport lacking ability to start by itself after some shaking.
And if I am wrong pressurizing outlets in the reverse order will put pistons in the right positions.
Maybe Vogel Schmierung didn't answer because they don't exist anymore? :)
At least the name doesn't, was bought by SKF. Though they still sell all the lubfirication thingys.
For them to say yes I guess you'd have to use their linear bearings and rails though ^^
Those valves are wild!
Schönes Video Marco! Und auch eine schöne Spindel die man da mal kurz gesehen hat...👌☺️Bin schon auf die ersten Späne gespannt!
( 3: 45 ) God , what a joy to look at .
Wooo cascaded valves. I haven't heard of them in a long time..
Oooh! Thank you!
hot tip, pour big jugs like that the other way up for better control
I guess, a small diaphragm pump right next to the target would be best since it won't be pushing a lot but will pull a lot(form a vacuum)
Hi marco nice movie. In 2015 I built a plunger driven oiler with 8 outlets, same principle as your oiler. Home built with my BF20L (G0704) a 4th axis is handy. So it possible to built a oiler. I have pictures and some drawings and so on....
Full 3-axis servo kit can be found here for much cheaper then the single unit kit: www.motioncontrolproducts.co.uk/products/15/170/cnc-3-axis-pronet-servo-kit---400w/
Mazak made the switch to grease several years ago.
I like the Fuchs name.
7:22 seems simple enough for diy on a mini lathe and a basic cnc ? given it's high price makes it the perfect diy project?
Dude I needed this Soo much for my diy cnc macine
Dude. 1 million subs. I swear. Soon. Such good videos
Just make a mini spinning sprinkler in containment with fixed.outer multiple outputs...
Very nice! I learned a lot about the system that is in my machine. Thanks!
You made me nostalgic for the days valve made games :(
Mobil Vactra 2, I've run YCM & Haas equipment.
Maybe drilling a hole in wipers and using small capillary tubes with less viscous oil together with solenoid valves. That is what i came up with my imaginary cnc, still not built completely :( dental technik have all sort of micro stuff
The colunms are not too thin for this kind of machine? Left-right movements and forward-backward. (may be you will need put there some triangles).
What will show the dial indicator with some load on it. (you can use a weight mesuer)
Is that lubricant suitable for latex?
I'll test it when I wear my catsuit next time
No, but Shell does have some synthetic lubricants in the range that are relatively latex stable. Reniso lubricants are all made from sweet crude, which causes natural rubber to rapidly degrade, unless it is properly vulcanised first.
If you're working with rubbers it's best to use water-based lubrication
Pretty interesting, man!!! 😮
Oh, about drones, never buy them. Build them! If you ever want to try, tell me and I can recommend some great channels where you can find every info about it. 😊
Utterly not useful in any way (for me!) but very interesting and entertaining. Thank you! 🙏
I think you're suffering from perfectionism. A true German..
