Hey guys,

New to woodworking, and even newer to CNC so please excuse the elementary questions.

I’m looking to create something similar to what’s attached, I essentially want to be able to cut out 26mm beech hardwood with perfect accuracy, what cnc machine would be appropriate for this? I’d really appreciate some help because I don’t know who to ask! Many thanks!

Hi,
a waterjet CNC cutter could do that. If you want to do it in metal then either waterjet or wireEDM.

That's not going to work too well on a CNC router. The combination of depth and sharp inside corners make it a better candidate for another process, like waterjet, as was suggested above.

Thank you, I’ve looked up prices for a water jet cnc cutter and they’re way out of my price range. I was looking to purchase something small for a reasonable price, any thoughts?

Look closely at the cuts and see it they where cut with a Scroll Saw by a skilled woodworker, if the surface is smooth in all places it most likely was done with a CNC water Jet machine but could be done with a Scroll Saw as well which would be the cheapest way to do it

Thank you, I actually asked the seller and he said it’s done with a scroll saw, I think currently that’ll be my best option, so time to get to training. Thanks so much guys!

Or you can build a CNC Scroll Saw.

Hi Usman -They would have been done on a laser cutter. Start researching them. Peter

Hi,
a laser cutter burns it way through materials and is going to char the wood.

You don't buy a waterjet, you take it to a company who has one and pay them to do it.

Hi Craig - That's why they are painted, a contract water cutter will cost too much for the job.... There will be heaps of laser cutters around that can do this... Peter

Hi Peter,

Glad you mentioned laser because that’s the first thing I tried, the workshop I go to has a trotec speedy 500. But I’m trying to cut 26mm beechwood. It struggled cutting 9mm, even if I cut 3 pieces together, it’s a lot of labour to then sand the charred parts which are unavoidable since I have to do it at full power, low speed and 3 passes.

There has to be a way to do it

Hi Usman - You need to find a more powerful laser that can cut clean and fast. Simples. If you don't want the charring then it has to be a router job. In this case you can't get the pointed details. You will have to round out details to suit the tooling. Maybe a rough pass then a finish cut in 2mm or 3mm dia tool. So you will have 1 or 1.5mm rads in the corners... I find two finishing passes are good with a small tool. At that diameter it maybe a burr vs a cutting tool . They are a bit flexy and the second finish cut will clean up some fuzz. I also sometimes offset the second finish pass 0.2mm Kyocera are good tools...But the laser is the correct weapon for that job. Peter

Yes, waterjet or scroll saw are really your only options here.

...3D Printer ?

[peteeng]

Hi Usman - Router or Mill you have the issue of tool radius and length. If you want a sharp corner you have to laser, waterjet or scroll saw. If you want to make many objects the scroll saw is out the laser is the answer. Or use a cheap router with a 3mm tool but then you will have to file the corners.... Peter

Go with high density foam and cut it with a laser.
