Small concrete cnc machine.

In this video I will build a cnc machine with a concrete bed. reinforced concrete is a good material for building a home loom because it is cheap and easy to mold. It also has anti-vibration properties.

the concrete is very economic and it 's similar to epoxy ! very amazing idea!

[@Rafaelguitarplayer]

really nice, dude.
Kudos on your build.

[@tinkot]

Amazing!

[@rameezsheikh7576]

Either you should use cast iron frame for reinforcing or not use any (except in the seats for linear rails ofcourse), because Mild steel tends to stretch if force is apllied.
That's what i got conclusion till now for concrete machine basse, no Glass fibre is going to work nor carbon fibre strends due to adhesion problem with concret.

Really loved it. Though about doing this, but haven't due to knowing concrete shrinks for many months, and even cracks on vibration. I was thinking on adding fiber reinforcement, but haven't yet. Do you have videos of it machining steel?

[@CreativeEngineering-er4rk]

I waited six months before starting to process the concrete part. Now the machine is more than two years old. He's fine. I process steel in the first series about the rotary axis and in the video about homemade cutters.

I also made mine with structural concrete 😊

Great! This is probably the most accessible material.

Hi a love your build. Keep up the awesome work. What is that other machine that you used to mill steel flat? Is that some other CNC. It seems to handle steel well enough.

[@CreativeEngineering-er4rk]

Hello. I processed the parts on my other machine. This is a large homemade CNC machine. I made it for woodworking. The working field is 2.7 by 1.7 meters. The X and Y axes are driven by a rack.

Good one, congrats

[@CreativeEngineering-er4rk]

Thanks

[@kieranh2005]

Hello. What is your XYZ travel and what rails/guides (size and length) did you use?

[@CreativeEngineering-er4rk]

Axial travel 300*300*300. Rails size 20. Rail length 550 mm.

[@imanghasemi5465]

Hello. Is it possible to share cad file of your cnc?
Thanks

[@CreativeEngineering-er4rk]

I didn't make a cad model. Too simple details. I just carried out calculations for deflection due to loads to find out the required thickness. The length of the rails and ball screws along all axes is 550 mm. The working stroke on all axes is 300 mm.

[@krunalpilojpara6009]

Very awesome work bro... I have a question that What is the tool with the spindle which you used for machine metal inlays for guide way etc.

[@CreativeEngineering-er4rk]

Spindle 2.2 kW, air cooling, 24000rpm. More suitable for wood and aluminum. Four-flute cutters 6 and 8 mm. Spindle speed - 4800 rpm. Feed 500-600mm/min.

Concrete bromlem is. It dry forever, and it shrinks

[@CreativeEngineering-er4rk]

Before processing, the concrete parts were left to stand for six months and covered with paint. This machine is already three years old and there are no problems with it.
