With this video i’ll show you my project: DIY micro VMC
The VMC was done with scraping the precision steel and without over-milling the X, Y and Z axis.
The costs oft he whole VMC without tools amounted to approx. 4000€.
XYZ travel: 330mm 220mm 450mm (360mm with tool)

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.

Sehr coole Maschine hast du dir da zusammen gebaut.

@edkcustoms Год назад

is the machine made from concrete or is that some kinda of epoxy granite casting? Looks realy good! love it!

@diycnc2023 Год назад

Hello, thx! It is made from uhpc, its a really strong concrete called nanodur

@jonjon3829 2 года назад

fill the neck with uhpc too, to get rid of the metal screeching sounds

@diycnc2023 2 года назад

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?

@diycnc2023 2 года назад

Hey, thanks!! I'm using a 1000w jmc servo.

@soulvagabond 2 года назад

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?

@diycnc2023 2 года назад

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. I changed to this bearings (bottom) € 82,46 | 1 Gruppe MOCHU 7007 7007C-2RZ-P4-TBTA 35x62x14 Sealed Schrägkugellager Geschwindigkeit Spindellager CNC a.aliexpress.com/_vrSFmS (and top) € 49,48 | 1 Para MOCHU 7006 7006C 2RZ P4 DT Eine 30x55x13 30x55x26 Versiegelt Schrägkugellager Geschwindigkeit Spindellager CNC ABEC-7 a.aliexpress.com/_vtipOw now 30min with 4000rpm 29C

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!

@@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

@sonnydavis5070 2 года назад

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.

Was the spindle bearing upgrade worth it?

@diycnc2023 2 года назад

Yes! Temperature drop from 52 to 29

this is epoxy granite cast?

No, UHPC

почему не сделал из эпоксидной станины?

@diycnc2023 9 месяцев назад

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/
