Your videos are amazing! The subtle humor is really nice. Thanks for balancing out the crap on TH-cam
Yeah really
Dry as toast German Humor is my favorite!
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 😥 😂 😭
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.
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.
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..."
Somehow you make industrial oil mildly pornographic. I'm amazed and disturbed at the same time.
mildly?
@@reps highly.
Extremly
@@reps und dann wundert man sich wieso Frauen in technischen Berufen so wenig anzutreffen sind.

progressive *Valve* ...
I see what you did there ;)
3:25 hot girl soaked in oil.
i see your a man of culture as well.
Ah yes

And I see you’re a fox of culture

It was weirdly sexual
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
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.
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.
Not boring at all, this is extremely useful and interesting information. Thanks a lot from Australia!
I'll always stick around to hear you talk about lube
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.
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
Double upload?? I’m not crying you are
the moment when Marco Reps is uploading a new Video... amazing
"The manufacture of my BALL..., Screws"
These innuendos and the way you phrased everything in the beginning was epic.
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
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.
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.
Hey Marco, I really like your videos, keep 'em coming buddy, they are highly entertaining, informative, interesting and worth learning from.
So glad to see another CNC update! Thanks, Marco!
Man, this valve block is the thing of beauty!
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.
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...
As a michinst/repairman, this was a valuable video. Thanks for sharing.
WOW! thanks for the lesson on lubrication, very impressive.
2 Videos at the same time ? In the middle of the Night ? Awesome !!
6:55 the voice delayed reference ( NICE! )
The props in this video are brilliant.
Great vid dude. I learn so much from your stuff. Thanks
Dude. 1 million subs. I swear. Soon. Such good videos
Dude I needed this Soo much for my diy cnc macine
Very nice! I learned a lot about the system that is in my machine. Thanks!
Those valves are wild!
Wow, impressive solution.
Thanks for sharing 👍😀
Schönes Video Marco! Und auch eine schöne Spindel die man da mal kurz gesehen hat...👌☺️Bin schon auf die ersten Späne gespannt!
See you soon? That was pretty soon.
Zwei Repsens für den Abend von einem, brillanter Einfall!
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.
Hell yes! I knew you wouldn't let us down :D
Thanks for the Vollgas/Full Throttle flashback at 6:50 ;) great video btw. Thats quite some "hobby machine"
anyone else finding these vids super relaxing?
Haha I just got the valve sound 🤣 that's why I watch all your videos at least three to four times
That's an exquisite capacitor indeed.
More interesting than I think you would have given it credit for.
Wooo cascaded valves. I haven't heard of them in a long time..
What was that model you drowned in oil? Looks like something i would like to print
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.
The other end of the lubrification spectrum was quite interesting.
DOUBLE VIDEO? Oh yes, how exquisite...
great video, man
That valve configuration reminds me of a dc to ac inverter.
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.
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.
I like the resin woman that you poured oil over
Amazing video
7:19 - Wow... never knew it was that complicated to distribute fluid/oil on a metering/manifold block.
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.
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
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!
Simply WOW!
correct me if im wrong but hass acually uses grease. and the oil pump is for the spindle
I missed you
nice links and all but I missed where you got that ground ballscrews?
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?
wade wade wat
doppel upload ?
mannoman, junge junge
:DDD
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.
Oooh! Thank you!
3:20 I think it's exactly where it's needed. Nothing better than an oiled up, naked... CNC machine.
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.
had to subscribe, very interesting
6:50 I thought my PC started CS by itself. Nice one
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)
It's a pogressive VALVe.....
VALVe theme starts in the background....
Perfect reference 10/10
Would there be the possibility to use PTFE Spray nozzles or PTFE liquid in general to lubricate certain parts?
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.
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.
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.
ballscrews for lubrication with grease and they which use liquid oil are ballscrews same or different? If not, which company produce ballscrews for lubrication with oil?
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 ;-)
6.50 I got a chuckle 😂... BTW my 6040.. I've never really oiled it only 3in1 once or twice... Do I need to step up my oil game
Hey Marco, if digital Vernier calipers are so accurate, then why aren't they used in CNC machining tools to take direct position feedback ? The position feedback from digital vernier calipers can be used to control the servo/stepper motors. Thought for the day !
Mazak made the switch to grease several years ago.
Mobil Vactra 2, I've run YCM & Haas equipment.
Lincoln / Masytec does central lubrication, perhaps you can find more reasonable priced central lubricators from them...
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).
Haas machines use a grease, but a relatively thin one at that
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.
You made me nostalgic for the days valve made games :(
( 3: 45 ) God , what a joy to look at .
I think you're suffering from perfectionism. A true German..
Btw where do you buy those blocks of aluminium?
But ... what's the type of the lead screw(s)? Seems round threaded, what can you say about them compared to trapezoidal ones?
Utterly not useful in any way (for me!) but very interesting and entertaining. Thank you! 🙏
+1 for knipex pliers wrench
I like the Fuchs name.
Marco, I'm just curious to know why you think that your lubrication system and flood cooling are incompatible?
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/
3:30 I'm not sure why, but that was really hot.
aaaand DEMONetized
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 :)
