« Part 4: preparing files for the CNC router. Part 5 of Kitty Condo - CAD/CAM primer series Part 6: a little color and a little glue... »

I’m in heaven since we upgraded our CNC table router ~ 2 years ago…

The boss gave me a budget of $20K and I found us a nice little plumb on the second hand market…

CNT Motion Systems 900 series, 5’x10’ gantry robot style table router, with the gantry going the 10’ direction….
10 HP Italian spindle, 8 station automatic tool changer, 15 HP vacuum table blower, WinCNC controlled…

I cut the parts with a 3/8” dia. spiral down Onsrud cutter in a single pass at 700 ipm.

Here she is in action…

I cut the parts for the Kitty Condo back in February…. and just dug them out and primed them with water based Killz yesterday….

that pretty much catches us up to time now…

I hope you enjoyed the primer on the CAD (design-model-detail) CAM (tool path-G code-cut) process, as I do it.

Next up is to add some color, cut the dowels to length and assemble…

(I may be installing a Thein plate in my single stage DC :^) and have to fix a leak in my air regulator first though :^(

Never a shortage of projects

nice . this one is a whole new level of production quality compared to what is available for the hobbyist. how much Z travel does it have?

The second hand market is really ripe for the picking these days… but you need 3 ph to take advantage of most of it. We purchased this machine two years old with low hours for $17,500 (cost well over 50 new) and got a boat load of tooling with it. And that’s not much more than a Shop Bot (if I’m not mistaken) We went and got it in our own truck and then paid to have the factory tech help with set up and training… So I did go over budget a little.

how much Z travel

7” ... so with a long cutter (say ~3”) you can still put a sizeable slab on there….

We’ve cut shapes with pockets in 3” high density foam sheets with it.

Did you learn CNC “G” code operation while in the USN, or as a machinist in a local fabrication shop? Russell

yeah, there are a lot of possibilities with these machines. what is it usually used for in your shop?

Handtooler:
Though I’m very interested in the machinery trade, I’m not any kind of trained machinist (nor do I play one on TV :^) I’m pretty much self taught in the CAD/CAM gig (building on an engineering background).

PurpLev:
The asset is shared by a couple different departments at work. Mostly we route ABS and HDPE sheet for use in custom hard shell case interiors & packaging assemblies. We routes plywood panels for partitions and timber cradles for use in custom crate assemblies, and we route store displays out of MDF as well as odd shaped counter tops & some sign work for the millwork dept.

Lesson learned…..

Water based Kills popped the texture on the particle board….

It was very smooth…. Now it’s textured.

Not really a big deal… I’m painting the finish coats of interior latex semi-gloss with a roller, so there was going to be texture anyways… Just not what I expected.

If I wanted to keep the surface smooth, I think I’d spray it with bin or Seal Coat shellac instead.

Live and learn.
