So here is my table build thread. Being I'm starting on this forum a bit late I'll try and post up the pics in order and let you know when I'm up to present day.It will be 5'x10' with an attached rotary axis for pipe/ sqr/rect tubing work. Is an air bladder style water table with linear rails, ac servo motors, and a THC from CandCNC. Will start out using a machine torch on the miller spectrum 875 autoline I have, hoping to upgrade to a larger hypertherm down the road, and everything is built big enough, to be able to handle thicker sheets and putting a oxy torch on at some point if I decide to as well. Aiming for 2,000 ipm + rapid travels with some high accel/decel. Any questions just ask.

Reply:elec mock up for cabinet
Reply:Well I got a little bit more done. Made up a quick jig to torch the slat holders out with by hand, got those installed and slats cut. Little bit of fine tuning to get all the slats in the same plane but not too bad. Trying to get some work to finish up on the lathe and mill this week yet but should have time to keep knocking a few things.
Reply:Not a whole lot done last few days, still trying to get some jobs out the door. Got the water diverter plates mounted and the side rail protectors screwed on, just clear s the face of the trucks, the servo gear reduction and rack and pinion will all be below that. Also found a chuck for the rotary on fleabay the other day, 12" 4 jaw self centering with 2 piece jaws and a 4-3/4" thu hole, will make some v notch jaws for sqr/rect tubing.And got it back up on the sawhorses to do some work on the elec cabinet etc without haveing to bend down to the floor, little bit more work and the base just might be ready for paint (after alot of prep work)
Reply:Rack came today.And I got the doors about done. Have to cut a piece of plexi for the door for the plasma and the left cabinet door is getting a filter put in it yet. Started getting some of the bulkhead stuff located and installed so I don't have to drill the wholes after its painted.Also sourced some decent sized bearings for the rotary, should be able to build a 4th axis spindle with about 4-1/4" thru hole.
Reply:Got a few parts painted yesterday and this morning. Most of the inside stuff won't get color. It's SPI epoxy primer and Napa crossfire single stage urethane. Color looks a little off, but it closely matches the color of the toolbox so it shouldn't look too bad. Got a few more things to do to the base like holes and mounts for the cabinet fans and filter and then I will probably start in on painting it and all the skirt panels before long, still have one end of the tank to paint as well but waiting for the epoxy to get good and hard before I set it down on a pallet.
Reply:Got all the skirt panels and door panels painted today, not really looking forward to painting the frame but I guess it has to be done.Was trying to figure out the gear reduction pulleys stuff and was getting difficult to get the reduction I wanted with the shaft sizes I needed. Looked around a bit at servo gearboxes and didn't like the prices, hopped on fleabay and happened to find 3 identical Atlanta servo worm gear reduction boxes with adjustable backlash down to less than 2 arc minute all for less than $100 ea shipped. Soon as they get here I can figure out just how long the side plates of the gantry have to be and can get to work on that finally. Might need a little bit of modifying or adapters to fit the servos I have to the gear units but its doable.Hopefully be painting the frame this week yet.
ReplyMy 5x10 plasma table buildrimer on, my back hurts. Thank god I got Dekups for the paint gun, kinda nice to be able to paint upside down while laying on the creeper under the thing.
Reply:Well got the frame painted with color today. Only a couple small parts left to paint, one or 2 to make yet that will need paint as well but glad to be done with the big stuff. Also got one of the servo worm drives in today, should work out perfect for my needs, 9.25:1 ratio (2 more should be here tomorrow that are identical to this one) and that is steep enough that the output can be turned by hand yet as well. Only real issue is I need to make adapter plates to mount the servos to them and I need to make shaft adapters as well. Biggest problem I face now is that the input shafts on these are a DIN 5480 Involute spline and to get a custom rotary broach would cost to much for the 3 I need made, maybe I'll have to find someone to wire edm them or somthingThey weigh a few pounds but with dual 750 watt ac servos I don't think it will matter much. This combined with the pinons I got should give me a rapid travel of 2100 ipm on both X and Y.
Reply:Set down, oriented and leveled today. Got a few panels put on, will wait to install all of them to do wiring etc. Starting to come together.Hopefully this week I'll get some side plates for the gantry drawn up and machined if not the whole gantry assembly built up.Its on blocks now to get enough clearance under the frame for my walkie stacker lift to be able to load sheets, when I get a jib crane put in in the near future the blocks will come out.
Reply:Got sideplates and angle bracket pcs made today. Also got adjustment plates for the gear boxes made as well, will have tap and bolts to finish those tomorrow. Then I can figure out the right off set to machine the shafts for the gear boxes to hold the pinions in the right spot.I set the gantry channel on top as well to get a feel for how it looks, hopefully tomorrow I can get some accurate measurements of the width and get the holes in the channel to bolt it to the angle brackets. Then I can finally start on the other linear rails and gear rack.....The sideplates wound up hanging down low a bit more than I would have liked, but had I known I would find the gearboxes I could of moved the rack up a bit tighter to the linear rail. I had left room for a possible belt reduction system. Being it is this low, it looks like I'll have to move my entrance hole for the torch cable as where it is now the side plate could catch it if it wasn't fastened down good.
Reply:Well, got the channel bolted on and the linear rails and rack bolted to it. Made some gusset plates today and got the conduit to feed motor wires etc to the far side of gantry mounted. Have to figure out my z axis and carriage and start building that soon. Hope to have shaft adapters ordered for the gearboxes this week and make some bolt pattern adapters, then maybe I can get the long axis running before long. Started looking at the cable trays too, will be building a tray to hold the long axis one on side of machine this week as well.And now up to present day, more to come
Reply:Man I would love to have a Plasma table. But as a hobby welder I can't justify the cost, nor the time it would take to build my own. Maybe when I'm retired...

ReplyMy 5x10 plasma table buildooks fantastic, do you know how much $$$ you have into it so far?Millermatic 252Lincoln 3200HDHobart Stickmate AC/DCHypertherm Powermax45
Reply:I don't have an exact amount, lost track. But being its for my commercial business (cnc machine shop) I wanted it done right, so I know I have more in it than I could of bought a bare bones low end one for, but should be a real good savings over say a torchmate X series or other commercial grade tables.I shopped around alot. The linear rails are Hiwin discontinued models (bought extra trucks for spares too), the gearboxes I got off ebay for next to nothing and I know if I had to buy those new they would be 2-3k each. The cable trays I got on a Cyber Monday deal for 35% off.Last edited by Pugs_; 04-14-2015 at 04:34 PM.

Reply:This thing is awesome! Well done!
ReplyMy 5x10 plasma table buildugs, any idea what the controls cost for this machine? Motors, drivers, cables, etc.  Also what software are you going to use to drive the machine?  Thanks
ReplyMy 5x10 plasma table buildooks good to me.Were the rack and rails hard to get aligned mounted on the side tubes?My name's not Jim....
Reply:Beautiful work - love it all.  Especially cool to see the detail you are putting into the wiring - like those DIN rail mounted components.  Cleans up wiring quite a bit.

Reply:This is certainly impressive. I love watching DIY CNC builds.I'm curious about the gearboxes. I'm not sure how they fit into the whole project, but it looks like they're driving the X axis. Doesn't this add backlash to the motion? Not sure what tolerances you're looking for, so I'm just curious.I look forward to watching your progress.

Reply:I think this is the nicest table I have ever seen.Going to ask a dumb question: What is the large tank for? Water? Will that circulate what is in the pan?Regards,RobGreat Basin WeldingInstagramBlue weldersRed weldersMy luscious Table DIY TIG Torch cooler
Reply:Nice job man!  I dig it.  CNC all the things!
Reply:I believe the tank is to allow for the table to be drained to get scrap out, and then refilled without having to use different water. Correct me if I'm wrong.There are no problems. There are only solutions. It's your duty to determine the right one.Hobart Handler 210Airco 225 Amp MSM Stinger
Reply:Makes sense.Regards,RobGreat Basin WeldingInstagramBlue weldersRed weldersMy luscious Table DIY TIG Torch cooler
Reply:Correct, its a bladder for the water, drain down to that and fish parts out or clean the top, plus less evap loss through the 2 small pipes vs the large table when not in use.

Reply:Touch of a side jaunt...Well the next project showed up this morning, old knee mill left this afternoon. Had to do a dual pick with our telehandler and the neighbors forklift to get it off the trailer, but then I got a few things removed like the lower die holder etc and was able to pick it up with our telehendler (rated at 7k lbs, this is around 12k....) and get it in the shop. Working on building some machinery skates that have been on the to do list for several years, then I can get this pushed back in its new home and get back to finishing the plasma table.Its a 8', 88 ton cnc press brake, current kpaps 3 control is dead along with fried boards etc but I got it for scrap price and will be putting a camsoft control on it run the back gauge and will convert the cylinders to a Y1, Y2 arrangement instead of the limit switches it has now. It even has servo controlled crowning too. Have to check the hydraulics out, if thats all good, then I should be able to get it up and running for fairly cheap.
ReplyMy 5x10 plasma table buildooking good Pugs. I have been following this thread on the zone. What brand of height control are you going to use?

Reply:VPT,You may want to move it a bit farther out from the window, so the ram can slide back a bit for the odd job. Or maybe there is room there, just hard to tell.

Reply:nope, Working on building some machinery skates so i can get it moved into posistion. Once thats done I can get back to focusing on making the plasma work, then I can work on the press more.I did strip 100 lbs of wire out of it (old and cracking, oil soaked), gutted both cabinets and did a bit of cleaning though. Been trying to get crops planted, should have that done tomorrow and the skates built by first part of next week.
ReplyMy 5x10 plasma table buildamn nice build.  Could you give details on the drivers,software and steppers used. 2phase or 5?  Unless I missed something and you're using servos.  Would like to build a small portable set up like the steel tailor types. Table would be better but space and portability seem more attractive.
