Cory builds a cnc plasma table

[YROC FAB.]

Well after years of dreaming and reading I went ahead and pulled the trigger on DIY plasma table kit.

This is all pretty new to me. I operated one when i was in college 6 years ago but have forgot most of it. Building the table is easy enough for me, the overwhelming part is the cad and all the settings and bs to operate one.

Some specs;Have 5x10 Magnum II precision plasma llc gantry kit.
Have Volex z axis with home brewed magnetic breakaway.
Have Hypertherm powermax 85 with (need>)machine torch.
Need Candcnc.com electronics jazz.
Have steel for table, need steel for water pan.

Some of the stuff included in the gantry kit. Very well organized and precise.

Kit showed up 5/18/2016
steel 5/26/2016

Fist i made me a magnetic breakaway for the machine torch for if/when i crash the machine i don't ruin a expensive torch.
The magnetic breakaway precsion plasma sells is listed for 250$. i spent 6$ on mine. 4$ in magnets and 2$ in counter sunk ss screws, scrap .25" plate.


I have 4 magnets on it now and i think 2 will be enough. i will try it out with the torch when it arrives and go from there. The ball bearings realign it perfectly when it time to stick it back on. The matching plates where drilled thru at the same time. They are .25" ball bearings i robbed from a pile of th400 parts.

Wow, the Powermax 85 is a big dude. You interested in thicker material or just cut speed ?

Both. Not just for the table but for heavy free hand gouging and demolition purposes. I would like to operate this table with more industrial things in mind as those clients are easier to deal with then one off artsy people. I use a 100 amp and 80 amp millers at work regualy and i knew i woulded want anything smaller. The powerpowermax 85 is rated the same as our 100amp miller.

Thank you. I am not sure I could find the space for this size but may try a small 2x2 or 4x4 to start with.

If you go 4x4 go with a 4x8 and only use 4x4 of the materials. The price difference is marginal, and you never know if you will grow.

Assembled gantry ends


Extruded aluminum axis with hardened steel v rail in it. The little trolley has matching v bearing rollers with the bottom two being on a cammed spacer to set the backlash.


All these holes are drilled and tapped for 5/16 bolts.


This is a transfer punch set for those of you that have never heard of them. They are the most handy thing in my world. For the new guys using them they are not center punches. you lightly tap them to make a center mark and then use a regular center punch to make a deep mark. beating on them will wear them out.(notice the largest one with black tape on it for when i needed a 5/8 transfer punch)


Assembled gantry.


Leveling feets for it.

Cut steel.





crs rails drilled




Built side by side






one leg was but welded out of left over drops to save on material.


All thats left over.

Everything is dead square and straight.



This nut is is has a hole drilled behind it. It is welded in the center of the table on both sides so i can bolt on a decent wheel and balance the table and move it on the the two wheels and simply unbolt once its moved.


Its been nice having two mig welders on a project of this size. I welded in the angled tube gussets to help support the table but mostly to store smaller lengths of tube and other metal stock in them. The horizontal braces are to store plate under it. i will weld some solid stock the full length of the horizontal x brace to simply slide plates in. steel for the water table will not be here till the 8th. Alex need to order our electronics still and yj_auzzy on the torch. Its a community table lol.


This is how it sits currently. I spent 12hr saturday and 8 on sunday. It slides smooth as butter. Its super solid as well. I fell like i could hang on it and zipline across.

Making good progress so far!

My only complaint about those kits is using the CRS for the rails. It's one of the least expensive ways to get motion control, but is very prone to collecting crap or rusting, and thus affecting your cuts. Just keep on top of keeping them clean/waxed/whatever and you should be golden.

Im familiar with this. The colleges torchmate uses CRS and we would give it a good blow down evertime we fired it up. I intend to plumb in a handy air nozzle for dedicated table blow job purposes. Some scotch brite and Wd-40 should keep them nice and shiny (have you seen my 2 year old buggy project? Not a spick of rust)

What kind of rails does yours use carl? crs den?

 

[YROC FAB.]

Really nice work! CRS stands for "cold rolled steel" I assume. Is that correct? If so, for the sake of learning, what would be more preferred?

Indeed. Its quite precise in raw form. Its the DOM of solid shapes.

I'd prefer some sort of linear rail with recirculating bearings probably. I've had zero problems with my Velox Z-axis in about 5 years of running my table.

No, mine has V-rails on all axes.

... for dedicated table blow job purposes...

Wait, what are you building?

Was yours DIY carl? Or turnkey? Brand?

You heard right.

Mine was DIY, I bought a PlasmaBot bracket kit from Shopdroids, and Pacific Bearing Linear extruded V-rails. Here's a pic of mine when it was all new, fresh, and clean.
