CNC router vacuum table

- I Needed a vacuum table for my CNC router, and after watching a few other great builds on TH-cam, I customized and designed one for my Axiom AR8 pro CNC router.
This build is simple and uses commonly available materials like MDF.
The video documents my table from start to finish (except for a sealing coat of paint)
the table size is 24" x 48" using the entire machinable area of my CNC.
If you choose to build your own then simply adapt the basic construction methods to match
the size of your router table. This is also a great CNC router beginner project & darn useful too.
Here is a link to my Google drive for a free download pdf file of companion drawings
and instructions for this vacuum table project
drive.google.c...
I only used 2 bits for this project, and both are essentials for any cnc tool-box:
All the cutting was done with a 1/4" spiral up-cut bit (1/4" shank)

And skimming the table surface was done with an 1-1/4" dia. bit (1/2" shank)

Your finger was so close to the blade on the table saw, please be careful, Thank you for your videos.
Thank you for you concern, perhaps the video angle makes it look a lot closer than it really is, I do try to be careful.
10 fingers, lots to spare, just be glad it wasn't his scrotum that close.
My left ear hurts after watching this
I'd love to see plans for this table if you have any available. Also, any chance of sharing the files used on the cnc for cutting the holes? Thanks, and great job on this!

I have a 2d line-drawing in autocad, which was imported into v-carve pro
Keep in mind that my table size is specific to my machine (axiom AR8 pro)
If any of that helps you feel free to drop me an email with your contact info
I don’t mind sharing

Great video
Now THAT, was a very good video. You're a pretty smart son-of-a...........
It was enough to make me subscribe to your channel. Looking forward to watching more of your content
Glad to enjoyed the vac table build, lots more cnc videos on the channel already you might
Like as well.
Thanks for watching and subscribing 👍
Nice video, thank you!
Just for future projects, take advantage of the t-slots, install your fasteners and t nuts into the piece you are trying to lock down, leave the nuts 'loose' , and slide the assembly into the slots... you won't have to make any special 'nuts'...unless you can't slide the piece in. This works very nicely and you would probably save the time of making the nuts. It might be a little tricky, you might need an extra hand to orient the nuts to go into the slots as you try to slide it in, but it should work.
The standard nuts jam to easily when sliding that far, at least they did for me. Didn’t take
Very long to drill and tap the 1/4-20 holes.
Thanks for watching
Never showed what vacuum pump you you used. That would be helpful
I did describe how the table was operated by a shop-vac vacuum, sorry you must have missed that part.
Thanks for watching 👍
Now I just designed a tool like this. I want to know, what flowrate (CFM) is needed?
Sorry but there are too many variations for me to give you that kind of advice.
My design uses a standard shop vac
It looks like you've lost a lot of Z depth this way. Have you considered removing the wasteboard that came with the machine?
Fred Sawtelle yes I have considered it, but I only put the vacuum table up there for thin sheets, it’s not always on the machine.
Let's see it in action now!
Christopher Bates keep an eye out for the next video
Thanks!
Hi Brian, quick question, have you used a bullnose router bit (to remove the square edges and sharp corners) with your CNC vacuum router? I'm working with 1/8" thick PolyCarbonate and wondering if it is possible to add a bead around the outside edge of the material without damaging the table in the process?
Adam, sorry but no I have not.
I have used a bee bit to make a chamfer to finish edges with no problem.
Thank you Brian for your quick response. I am thinking about purchasing a CNC machine for a project but I'm very price sensitive, from your experience, would you recommend a buying a CNC kit and build it yourself or buy a new?
@@adamb.745
The only kit I have ever put together was an AVID cnc kit, which was great.
But they are also more pro grade and not inexpensive
@@BuildswithBrian Thank you very much Brian. Great input. Hope you and your family have a wonderful Thanksgiving! Thank you.
You’re welcome Adam.
Wishing you and yours a Mary holiday season as well
I’ve been considering doing this for my CNC but have heard that a shop vac will burn out if there isn’t much airflow over the motor from the suction. How has your shop vac held up? Is the mdf porous enough that even when the holes are all covered there is some air flow through the vacuum to cool the motor?
Most, but I can’t say all of course, shop vacs have a separate fan that cools the motor independently of the vacuum flow.
Mine is like that. And I have literally several hundred hours of use on the vac table with it.
And i have a small ,about 1/2”, hole that allows a tiny amount of air even if all holes are covered.
Been working fine for me.
@@BuildswithBrian what shop vac do you use for the vacuum table?
@@homehackshowtos ridged 5 gallon
@@BuildswithBrian perfect that’s what I have
Good luck with your build !
Hi everyone....I want to ask all interested viewers for some input on the next video....
another CNC project ? a project with-out the CNC router ? A work-shop tip ? A tool review ?
please jot down any ideas or input in the comments section below... Thanks
@Brian Ofcourse
It appears you permanently glued the entirety of the box.
Is the vacuum sufficient enough to remove all the sawdust and debris that falls inside the box while machining?
What do you use to cover holes that are located on the perimeter of your workpiece?
How weak does the vacuum become as the cuts progress (especially when cookie-cutting a bunch of smaller parts)?
:
@@criticallook1352 yes the box is permanently glued, so it it is totally sealed.
So for I have found the vacuum is sufficient to keep it clear, it’s been almost 3 years with no problems.
I usually use scrap pieces of thin plastic to cover any open holes, but I also use masking tape and even have used Kraft paper with success.
And of course the vacuum strength descreases proportional to the cut areas but it it very hard to give any type of measurable amount since it it unique to the items cut.
All I can say is that most vacuum system’s including mine have limitations with small parts.
Thanks for watching,
Hope you found it helpful.

Thanks Brian. Yes, you were very helpful, but I find it odd that you use the wrappers that individually cover Kraft cheese to block the unused holes of the vacuum table!!? 🥁 _rimshot_

😆😆😆
Hey GREAT approach. Could i ask you what type of machinery is the yellow device @ 0:10?
Karveit Studio
It is a press brake
For bending sheet-metal, it is air powered, and thank you hope you enjoyed the video
@@BuildswithBrian Thanks, ok. what brand is it if you don't mind me asking?
Atek is the manufacturer

Ok thanx @@BuildswithBrian .
Which vacuum motor are you using ? What size is the table ?
Philip, It is a 5 peak HP, 16 gallon shop vac, Rigid brand
the table size is 24" x 48"
sorry for the delay in answering, we must be in different time zones
@@BuildswithBrian Great video, thanks a lot. Could you tell me please if the shop vac that you bought is able to work for several hours a day without the risk of burning the engine?
@@bbeelluuttaakk the ridged vac I am using is still kicking after more than 2 straight hours of use.
nice job, sir
Thank you, hope it was helpful
What type of bit are you using for engraving?
Do you have to be more specific, engraving what ?
@@BuildswithBrian The two layer black and white plastic sheet. Do you have a video showing the setup to engrave placards using that material. I have the same material from BF plastic.
@@johncarr123 OK, I’ve used many different kinds of bits, 45 degree 60 degree and 30 degree v point engraving bits.
Also with single line fonts I have used 1/32 and 1/64 end mills.
To cut out the profiles I use a 1/16 spiral down cut bit and it works the best
@@BuildswithBrian I hate to be a pain. Can you list the part numbers for the bits you used 1/64, 1/32, 1/16. Any chance do you have a video of setting up the CNC to make and cut placards?
@@johncarr123 shoot me an email To remind me, I can’t get those for you today, and no I don’t have a video describing the process yet. If I get enough interest I might make one though
your shop is WAY too clean to have been doing any real work ! LOL FAKE
What would be the point of faking a workshop for a TH-cam video??
Honestly, you trolls are mindless.
