Good sir - Your channel might not be very big for whatever reason, but I can truly appreciate the sheer level of talent and skill involved in what you've accomplished here and otherwise. Most people sadly aren't enlightened enough to comprehend just how freaking impressive this actually is in practice. Major props, subscribtion well earned.

could you explain the small rod on either side of the linear rails around 9:19 please?

i not understand have you closed loop stepper motors, my machine have open loop, stepper same size but not can run fast all axis lose steps, maximum about 900mm/min 1000mm lose steps lot. i run motors 40V 3A. DM 556 drivers. linuxcnc 2,8,4 version. spindle not good , only 800W aircooled. ER16

Terrific vid. Thank you.

1 can it do 3 axis work or only horizontal? Can ir mill a ball? 2 how much did it cost?

Wow, this turned out amazing! VERY inspiring indeed. With all of the painstaking precision you put into this what kinds of parts and projects are you planning? OR was this the project in itself?

You've inspired me to build a concrete / epoxy granite CNC. I had a really crappy thing made out of wood that was more or less useless ("Bob's CNC"). I knew nothing about CNC when I bought the kit, no experience. I fiddled with that damn thing for days trying to carve a simple circuit board with big traces for a Tesla coil project. I ended up carving it by hand with a Dremel and it turned out better in 1/4 of the time I spent fiddling with the "cnc". I have been studying up on metrology, scraping lapping etc., and acquiring some decent starter tools. I just got a cheap chinese mini lathe, that will be my first project to improve to whatever accuracy I can get and learn from. I have a "Sieg" X2D mini mill from Little Machine Shop on the way to fiddle with for a while as well. I think these will be a good learning foundation and provide the ability to make some working parts and fixtures for a precision CNC milling machine later on. Then I can use that to create better parts for it, and then also build a concrete/ epoxy granite precision lathe. I make optical parts for my planetarium hobby and it's getting to the point where I need much more precision and I don't think I'll get lucky and have a used Haas VF-2 cross my path at anything I could possibly afford.

Hello Alex

Thank you for sharing your knowledge with us!

Parts made from what aluminium alloy? Fibral?

Hi, nice project. what is the spindle motor rating, like power in KW, RPM and torque. Thanks

how % difference and means to performance of your machine from using linear rail guideway @ 25mm instead of those bigger you use now ?

Can you list what spindle and spindle motor also linear scales please

How does it going?

Hi Alex, a new video showing the accuracy/tolerances achievable with the machine is highly appreciated. Since the machine is now two years (or more) old and you used a UHPC, some information on shrinking/cracking/etc which is usually present in concrete based VMC's is very valuable to the community.

I am very interested in calipers and how to get accurate measurement of watch crystals. Experts recommend taking a few measurements to be sure. But if the arms of the caliper can only measure the diameter, then why aren't all the measurements exactly the same? (This question is because I am having difficulty with using the calipers.) Thanks!

Wow, finally someone talking about the leveling problems they are having, and how crazy it actually is to get these things corrected. Thank you for this video, as I am having the same problems with my lathe build, and all of the videos out there doing these builds make them look so simple, but it really isn't when it comes to the fine tuning and leveling... Huge pain in the ass!

Hello! Serious project! Is the information private? What concrete or mixture did you use to make the machine bed? Have you noticed any deformations or changes in the geometry of the machine over time?

THIS MACHINE IS INSANE ! ( in a good way ) Is this UHPC or "normal" Concrete ?? and Greetings From Finland

What size are those rails?

How many you spend for all the parts to build this mill ?

You didn't explain the working of those cylinders on the zaxis.

Where did you get that precision water level and the X bar

Hi Alex, nice machine you build there. may i know the detail of servo motor used for the spindle is ?and what is the maximum speed you get with your spindle...thank you

Nice. I like the idea with making the electrical cabinet with aluminium extrusions and flat plates so you dont have to bend the thick aluminium plates.

I haven't done scraping since I was an apprentice. Followed by frosting to allow oil space.

Hi , are you alive ? Nothing for a year

What’s the make and model of the spindle motor you’re using?

Поставь воздушную турбину пусть создает небольшое давление воздуха в зоне механики.

I noticed there's no usage of coolant . . . why?

How did you manage to get good and true holes on drill press without cross table? I could never get serious precision on drill press.

Genial el armado de la maquina

😮

uses multi million dollar 5axis machine. LMAO

Hi Allex, would you like to Share the the drawing of this project!! We can try to learn something! Please..

Amazing results!

what grit size is recommended for the diamond lapping wheel?

Сказать, что работа отличная; ничего не сказать - эта работа образец того как техническое творчество превращается в высокое искусство, пробуждающее, не менее высокие духовные чувства!

Congrats, Alex.Excellent job

buy a new machine quickly

Hallo ! Is there a way to reuse all the acrylic shavings? Like maybe heat them all together? Also, do you use Novus polishing for scratches and renewal on your acrylic pieces? Or something more effective? Thank you 🇩🇪

Tell me why do you install scales? Are they for compensating any wear that might show up on ball screw with age?

Amazing! I gotta go back and watch your previous build videos. Hope you get some more content out there soon. Are you planning on doing flood cooling at some point?

It was an interesting adventure!

താങ്ക്യൂ

I followed the whole series, perfect work and high accuracy. How long did the work take and how much was the cost there is no doubt that you made a very big effort

Love this. Best content. I knew everything but i LIKE TO SE U KNOW THE WINNING WAY

Some things are beyond reason or practicality !! They are born from emotion and a thirst for knowledge.. Anyone with enough money can pay £30.000 for a machine , but then it’s “just a machine “….. “Bernard”. Is a thing of beauty..💪🏻💪🏻💪🏻

these thing dont look to accurate is sad this is one of the most advance ways to measure the smallest digits
