The Best built on youtube without exception. I'm a CNC Machinist having setup several mills and that was amazing work. You need to bolt it down to a good concrete floor and finish leveling to axis's and you can get it to read more accurately, plus it will hold tighter tolerances consistently. At that stage a precision level is necessary to use complete leveling and to obtain accuracy. Look up how to level a cnc vmc and get the pdf manual on a Mazak or a major machine tool builder.
Thx! I leveled the mill but i can not bolt it into my floor (heating floor). Accuracy is for my hobby needs more than enough. (20mm circle: 19,996 - 19,993) Thx for your comment.
Hi mate, I'm just getting the metal together for a frame, going to be bit bigger than this one, prob triple the weight tho, frame double in thickness (both tube and wall) and half the height to ensure frame is sturdy as hell My plan is to use a bt30 spindle as the main one, with ceramic bearings and a secondary high speed spindle for precision work. I want to be able to drill gear train holes for mechanic watches (closer to pocket watch sizes, so much larger than modern wrist watches but) Gonna use roller bearing linear rails, c0 ball screws, glass scales for closed loop survos And ALOTTTT of time scraping in all the mating surfaces and ensuring everything is flawless Oh and heat treating the frame after welding before granite Am I being unrealistic trying to get +- 1 or 2 micron accuracy over a 3"sq area? Thanks
Servus! Ja vor dem Verguss der Z Achse. Hab das schlussendlich mit weichgeglühtem Kupferdraht gemacht, da das mit den Madenschrauben zu ungenau/nervig war. Den Kupferdaht konnte man schön und gleichmäßig pressen und das ganze ausrichten. (3 Seitig)
Hi there! ive got a question. what did you use to "level" the Z colum to the base? like some sort of epoxy? im building a similar machine right now but i do not know how to level it properly! Tnx in advance!
nice, have a question about the green spindle.. did you buy the cheapest version with the purpose of upgrading the bearings right away? Which bearings would you recommend to upgrade to?
Hello, yes, i bought the cheapest version and with the purpose of upgrading, becouse the original bearings are normal ball bearings. For assembly a fridge for cooling the spindle down and a baking oven for heating the bearings (100C) is ok.

Is there any chance you'd be willing to share a .step file or equivalent of the design with a BOM. I know is asking a lot. I've dreamt of building something exactly like this. I have the build experience but not the design experience. I've looked for ever to find such plans with no results. Especially with such a great design. It would be to costly for me to just wing it. Please consider it.
Hello, because epoxy resin is much more complicated to use. The concrete is easy, you only need a mixer. Also machine building companys use concrete: www.durcrete.de/

Very nice machine! Love it 😍
Hammer Projekt! Glückwunsch zur Fertigstellung.👍
Gefällt mir sehr gut, danke fürs Zeigen!
thx
Nice build! I am looking forward to more videos!
Thx!
Super Projekt! Habe den Bau schon im Discord verfolgt, Glückwunsch zu der tollen Maschine....👍
is the machine made from concrete or is that some kinda of epoxy granite casting? Looks realy good! love it!
Hello, thx!
It is made from uhpc, its a really strong concrete called nanodur
Hi, wie hast du die Ausrichtung der Z-Achse durchgeführt, bevor alles vergossen wurde? Hast du Gewindestifte verwendet um den Turm zu "kippen"?
Servus!
Ja vor dem Verguss der Z Achse.
Hab das schlussendlich mit weichgeglühtem Kupferdraht gemacht, da das mit den Madenschrauben zu ungenau/nervig war. Den Kupferdaht konnte man schön und gleichmäßig pressen und das ganze ausrichten. (3 Seitig)

fill the neck with uhpc too, to get rid of the metal screeching sounds
The sound is ok in real. In the video the sound is ugly.

Awesome build! Neat and compact, one question, what motor did you use to drive the spindle?
Hey, thanks!!
I'm using a 1000w jmc servo.

Hello search on grabcad.com
Great build, thanks for sharing! Looking forward for more videos. Quick question, what kind of concrete did you use to make the casting?
thanks! i used nanodur (tegno)

@@diycnc2023 Did you hear about sika 212 grout ? I think that they are similar ones... no epoxy then?
@@hernancurras hello sika 212 has E-Modul 15000 N/mm2
Uhpc has E-Modul 80000 N/mm2
More is better
Was the spindle bearing upgrade worth it?
Yes! Temperature drop from 52 to 29

@@diycnc2023 did you measure deflection of column over base? ( If you push top of the column forward)
@@vnuendru1 hello, i did a rudimentary test with a 0,01 dailgauge. I pushed the column to the side with my bodyweight, no change on the dailgauge.
почему не сделал из эпоксидной станины?
Hello,
because epoxy resin is much more complicated to use. The concrete is easy, you only need a mixer.

this is epoxy granite cast?
No, UHPC
