Tthis was the most complex part so far of my restoration project. There is still a lot of work to come Hope you will enjoy the video :) If you like the video please share it with your friend to support my work :)
Could you please tell me what type of degreaser are you using? I have tryed a degreaser for the oven, caustic soda and kerosene. Only kerosene works but smells a lot. Thanks
@@AdamMaszynotwor Cześć Adam,mi to się marzy instalacja elektryczna w nowym warsztacie ;) Kolega elektryk zaczął prawie 2 lata temu... Lampy już wiszą:) -Kiedyś sam sobie wszystko robiłem,teraz mi brakuje czasu :(
@16:32, that mount, gets tightened (4 allen cap head bolts) after the table is on the machine, and the linear bearings are aligned and the ball lead screw is aligned in both + & - of the tables travel.. it is tight to get in there to do so, but cutting an allen wrench short on the short end is the "custom tool" required for that aspect.. all in efforts to not stress the ball lead screw with two harsh contact points from the carrier being canted.. instead of the entire track of balls sharing the load.. can mean the difference of 400 hours of life to 10,000 hours of use on the ball lead screw.. Good luck. well done by the way. I have enjoyed watching somebody else do the work throwing these heavy casting around for once...
Is there any specific reason you are not tramming in any of your Axis? Once you start running this machine, you are bound to have errors which will require a teardown and proper tramming. Even the level and parallelism between two adjacent guides are not being checked.? Also, why are you not folding over the locking tabs of the lock washers?
That's a very good question! I'm doing a similar tear down and clean / fix of a VMC and I'm very careful what I take apart and what I don't (ball screws for instance - my machine is all box ways so I don't have to worry about linear rail alignment) to not have to re-align things later.
I admire your tanacity and ambition on the rebuild but I need to point out some pretty major mistakes before you go furthered an run into issues. Taking the wire wheel to the truck pasds was a big mistake they all need to be the same height to within a couple of microns you will now need to measure and scrape/grind them back into spec. When you refitted the linear rails on the y axis you need to use a dial indicator and check parallelism between the two rails, it needs to be 0.01mm or less over the whole length same for height between all truck pads. Once you have the rails aligned you them need to align the ball screw to the rails that has to be parallel side to side and up and down within 0.01mm to the rails. When you mount the top table x axis you need to mount the rails to the underside of the table first thin indicate between the rails for parralesism and height then you flip it over and lightly tighten the trucks to about 10ftlbs you then need to use a granite square and indicate the x and y axis into each other to 0.01mm or less then you can torq the x trucks down to about 28ftlbs. Once that is done you need to check the x axis ball screw is alligned side to side and I. Height with the rails and move the end bearing blocks as necessary to correct any screw runout. Once that is good you can then bolt up the x screw ball nut to the casting. I don't want you to be discouraged but I need to let you know so you don't ruin your machine. If you like I can send you some manuals that detail and illustrate these procedures. The worst part for you I think will be dialing the column back in, that is going to be really hard without some special equipment, you really shouldn't have seperated them as all you can do to try and align it now is to hit on the column with a big hammer to try and shift it one way or another while a buddy watches a dial indicator.
Hey, I know im kina late but I just stumbled across this video. I currently study mechanical engineering and I am interested in this kind of topic. You mentioned that you have some manuals detailing the process. I was wondering if you know literature that goes further into this? Did a quick google search but found nothing that seems to go into detail. Would be nice if you could help me out.
Could you please tell us what the degreaser is... and is it the same as you used for the first clean in the yard when you initially brought the machine home? How did you manage to convince your wife to let you build the workshop inside the house?
Dvě připomínky: 1) ložiska by se nikdy neměly do díry natlačovat přes středovej kroužek - obtisknou se ti kuličky do vnějšího a ložisko defakto v pr (samo dost záleží jak dobře tam šly/jakou silou si je musel natahovat) 2) po osazení lineárních vedení to chce vzít hodinky a změřit, jestli jsou rovnoběžný Mimochodem, doporučuju víc zdrojů světla, z vlastní zkušenosti můžu říct, že u jednoho boďáku se dělá hrozně blbě (stačí když se přidělá zářivka nastojato na starej věšák na kabáty, je to přenosný a dává to pěkný neostrý světlo). Těším se na další video :)
Marek dobra robota, ale dako ma desi, ze som ta pocas celej instalacie vedeni a skrutky nevidel vytiahnut indikator aby si meral paralelnost pohybu medzi kolajnicami tej istej osi, ci paralelnost osi otacania gulickovej skurtky s linearnymi vedenami. Rozumiem, ze masina je stara a vymlatena, ale stale je dobre aspon vidiet co sa deje. Videl som ako sa generalkuju profesionalne velke CNCcka od piky (komplet vymena pohybovych elementov za nove a kalibracia) takze mam prehladm co sa robi, ked sa masina dava opat do svojich povodnych specifikacii a tolerancii :D Kazdopadne parada, ta masivna liatinova zakladna ti do buducnosti dava vela moznosti co dalej s tou masinou :)
Ahoj diky za komentár, čo sa týka kalibrovania to má ešte len čaká. Chcem ponahadzovat motori a sfunkčniť to. Predsa len sa to trosku lepšie dolaďuje keď niekoľko stoviek kilové komponenty nemusíš posúvať ručne 😁
@@MarekTabi Takto... uz ked nasadzujes linearne vedenia, je dolezite uz vtedy zacat merat mat ich v com najlepsom stave. Oni pouzivali aj take specialne utierky aby ich cistili a potom opatrne polozili na plochu na ktorej su prisrobovane. Aj na top masinach som napr videl, ze technik podkladal foliu pod kolajnicu, aby vyrovnal par mikronov Anyway nechcem sa moc rozpisovat ale sranda bola aj napr sledovat, ako technici (od DMG Mori) zbuchali OSB dosky okolo masiny, mecjali klimatizacnu jednotku pracovat 48 hodin, aby celu masinu rovnomerne vychladili na urcitu teplotu a potom zacali merat a hladat kde vznikaju nepresnosti :D Mat masinu geometricky presnu je umenie a veda zaroven. Typek zo skody co robil velke horizontky hovori, ze sa to uci cely zivot a kazdu chvilu prichadzaju na nove a nove triky.
great work ... but you never want to move any bearing type(ball screws, linear, radial, axial etc ) without lubricant... even less with weight over it you cut the lifespan of that component significantly
In any video i saw he using any lubricant in any bearing ! so much work done. in short time he will have to do again, becouse bearing will br worn again .
All this is good, but for what purpose do you make such a machine? You have that mass production. What will you do on it, how will you return the money you spent. What is the end result?
Not even close to restoration! Why didnt you scrape the surfaces? You've just cleaned the base rails and carriages and put new paint on it. the geometry could be still on poor level. And all the waste watter is spiled on the ground!
@@manifestoc why would you scrape the base? It's untouched non bearing surface under the rails, without wear. And rails and carriages are not necessary to change if the state is adequate and you are on a budget.
@@MrKRSO talking about budget is really important! Carriages have to be changed after 120-150 km of travel, if you see rust on rails you have to change them. The base? Take the metrology equipment and check the sequence and parallelism on undertail surfaces.after you've cleaned the rust and dirt... An you could check the rails on constant hight...
@@manifestoc obviously this guy is not working on your kind of budget. New linear rail and carriages would probably cost the same as the total cost of this project. He is getting a super machine if you account for the budget.
This machine was ready for scrapping. All axes have been blocket. I saved this machines from destruction and now is my goal is to make this machine work 😊 when disassembling, i found that it is in quite good condition 😊
@@MarekTabi No surprise it wasn't working with all that crap caked on all over it, nice work with the restoration, how far away from getting it going are you?
They are usually outdated in electronic aspect and people supposed that the whole piece is a scrap. Upgrading it is not a big deal in this time of year.
@@MarekTabi not sure bro! First time seeing you in ages, used to watch you a year and a bit ago, but you tube never sends me anything you just recently showed back up!
