CNC router site prep

So the CNC router is being built at Multicam, so we should probably make sure we are ready to receive it.

I talked to Lance last night as he was doing some repair work on the outlets in the workshop and he informed me that all of our panels are full and if we want to run any more high voltage circuits, like for the CNC router and the vacuum pump, that we will need another panel.

Is that the case and if so shouldn’t we get that going ASAP so we don’t have a scenario of having a CNC router and not being able to use it?

The router itself takes 208 3 phase. The vacuum pump (needed for holding down sheets) takes 208 3 phase as well. I don’t know how many amps at this point but the router spindle is 4 HP Perske spindle and the vacuum pump is 8.5 HP 2 stage blower.

The router will also need compressed air and dust collection.

Also to take into consideration is moving the router from the loading dock to the final destination in the wood shop.If the forklift will fit through the wood shop door this will probably work, otherwise casters, or pallette jacks may work. The machine will be fairly bulky and somewhat heavy.

Ahhhh CNC… drool

We’re actually getting the 17HP vacuum. In addition to electrical, we need to run PVC for the vacuum.

I think we also need to think about adding compressed air pump capacity. The current small pump does not have enough capacity to keep the HAAS happy (Low Air Pressure Alarm) on longer jobs. If we have three machines (HAAS, MultiCAM and the PlasmaCAM) all running I don’t think our compressed air system can keep up.

The dust collection is pretty much run unless we plan to move it from the far corner of the woodshop. It has a 5 inch port ready but if we really needed to we can run 6 inch ducting.

Do we have a delivery date?

It’s temporary. The motor for the Husky is at the shop being evaluated. A new one will be $850. Come to the BOD meeting to support buying a good compressor!

What is the footprint of the cnc router, something like 7x12 feet? (it’s 7x15) Will the scrap wood bin still fit in the woodshop?

The forklift does fit through the door, will take shuffling around lots of tools to get it to the corner

Here are the physical dimensions:

Model 1-204
Length 177" (14’9")
Width 81" (6’9")
Height 54" (4’6")
working area 60"x120" (5’x10’)
3157 lbs

I am working on the electrical front where we need to bring in a new panel.

on the Compressed Air Front we already have lines that go above the area so it will be easy to tap into them.

On the Vacuum Front it would be very helpful if someone ran PVC Pipe from the Air Compressor area to the area where the CNC Router is going.

On the Data I ran Ethernet a couple months back that can be use for either an additional Camera of the Data Link to the CNC Router/Computer.

On the Cooling Front it would be extremely helpful for someone to find a product for cooling when cutting AL.
I am thinking this but http://www.mmsonline.com/articles/alcohol-based-coolant-offers-environmentally-friendly-machining But I have not found a product yet.

I taped off an area of 7 x 12 in that corner but I can add on a few extra feet. How much area is needed to get around the machine for maintenance?

The wood storage will have to move out to the main area.

Those shelves currently in wood shop will be leaving, we might keep one but I definitely want 2 to go.

do we have to do any grounding with the PVC pipe? what happens if saw dust gets sucked into the vacuum?

Would be a run of ~220 feet of pvc if you didn’t go diagonally, sounds like building a platform on top of the forklift might be useful…

In order for the vacuum pump to be as effective as possible, you’ll want to keep plumbing runs as short as possible. 220’ will result in loss of lots of vacuum power.

Normally the way you run the router is with a sheet of MDF on the table that has had the top and bottom surfaces faced. Believe it or not MDF is porous enough to pull a vacuum through (with top and bottom faced). It also acts as a spoil board to protect the table from accidents. If the spoil board gets too many gouges in it you just resurface the top using a fly cutter. When the spoilboard gets too thin, you replace it and start again. I also saw some techs at Multicam route a grid pattern in the bottom surface of the spoil board to help air flow. With the phenolic tables this isn’t as much of an issue but with the table we are getting it might help.

I’m pretty sure table will have a phenolic top. They seem to put them on all models.

Although most of the machines Multicam makes are 1" thick phenolic with a grid cut into it, the 1000 series machine I saw a quote for DMS had the t-slot table - which does have some thin phenolic glued to the top, but its way thinner and does not have a grid cut into it. Instead they have a series of holes drilled into chambers between t-slots and those chambers are run to the plumbing in the back. It looks like this but with a grid of holes cut into it:

The normal 1" thick phenolic tables look like this with the grid cut into them:

Thanks,

This is what I got from Jeff at Multicam
"The router is configured for 208V, 3 phase and the vacuum pump is rated at 230V 3 phase, as we discussed.

Attached is the layout drawing for the router table and a drawing of the 17 HP Regenerative Pump (Blower). I would try to leave at least two feet around the perimeter of the table for accessibility. Regarding the pump, we recommend locating it as close to table with as few right angle duct bends as possible to minimize pressure loss. 200 feet will probably cause significant pressure loss, so I would consider setting aside space in the woodshop for the vacuum. If it is too loud, it’s quite easy to build a simple sound baffle box around it.
"

Yup. Just like I said. 200’ is too far.

Ah, I see that now. When we took the tour he was talking up the replaceable top, and how the first thing a new router did was cut its top.

Update on Electrical @bgangwere brought Bob from White electric in and I am talking to him now about getting a 200 Amp Panel installed I am also contacting Scott-Dell for a quote (LandLord recommendation)

I don’t have any pricing info yet

Should we consider moving things around in the space?

Idea 1) Put the CNC Router where the Hass is. Move the Haas to where the large Lathe is. Build a room just for the CNC Router with curtains (or Real walls) and run dust collection from wood working.

Idea 2) Split the distance and put it where laser is. For this to happen another ventilation hole needs to be made some place else for the laser.

Idea 3) Similar to option 1 and 2, move laser to use same ventilation as kilns. I thought about placing it on the wall between the doors where the Emco is now You would need to move the Hass and some of the other equipment.

Idea 3.5) Move laser to use the same ventilation as the kilns. Move foundry spinning wheels and stuff to arts room Move non messy arts stuff like the computers, large format stuff to pillar room. Leave the kilns there as they are only fired every so often anyways.

These are just ideas and not fully thought out, so feel free to shoot down any of them.
