Does anyone know of a company with a CNC bandsaw that might do some work for my small business? Preferably in Utah or the western US?

Thanks in advance,
Dave

Hi Dave. What are you cutting that requires this saw. Could a CNC router possibly perform the same task?

I’d never even heard of a CNC bandsaw.
Do you mean like this?

Thanks for chiming in. Yep Ger21, that is exactly what I am looking for. Maybe I need to contact the distributor to see who has bought one. I’m guessing it would be owned by a furniture mfg. for cutting chair parts. I cut stacks of curved strips of poplar, paulownia and maple to assemble the cores for backcountry snowboards. (They split apart down the center and allow you to climb with climbing skins and then go back together for descent.) The thickest strip s I cut are 1/4” at the tips and 9/16ths in the middle. I glue up the cores then recess hard maple or black locust on the outside edges, then finish sand them on an open drum sander before laminating with carbon, innegra and veneer.

Finns, it seems like the CNC router bit would create a lot of waste cutting out stacked curved strips and ideally I’d be cutting it out of 6/4 or 8/4 stock. The CNC Bandsaw seems like it would just scream through poplar and paulownia at any thickness with little waste. Buying one is not in the numbers.

Presently I place a plywood template over my stock (5/4) and then router out the bottom of the curved strip because this side will be the base of the board and needs to be pretty flat to laminate and work correctly. Then I trace out the thickness profile with a pre-cut strip and cut out the top of the curve with a jigsaw. (I should probably get a basic bandsaw for making top cuts.) It leaves the top edges with a fair bit of variation. If I was ever going to saddle up and make more than 10-15 boards a year, this process is a bit too time consuming because it requires a lot more sanding and checking to keep the top flat and thickness uniform from edge to edge. Any ideas on a better way?

Now that I see what you’re doing, it all makes sense. To answer your original question, I am not aware of anyone who has the equipment you’re looking for but will yell if I come across one. Heck of a machine that GR21 linked here. Nice boards by the way!

Thanks, yeah I reckon there aren’t any of these saws in a smaller cabinet or furniture shop nearby, probably just owned by larger mfgs, I’m guessing mostly overseas.

I would think that almost anyone that had one of those would more than likely not be willing to do batch work for you since it would take the machine away from it’s normal production work. It just doesn’t look like a machine that a smaller shop might have .

yeah, I see that now. They probably wouldn’t be letting it or its operator sit still

There is a way to use a template on a bandsaw, which might be a decent intermediate step for you. It isn’t quite CNC accurate, but it is faster than just cutting by hand or with a jigsaw.

You do need templates, so if you are cutting many pieces of the very same part it will speed things up. But, if you’re cutting slight variations on every part, then it might not work so well.

The technique is shown in one or both of the common bandsaw books, since I have both I forgot which one I found it in.
