Thread: Cutting angled slots in 12mm ply

You could use a swivelling head, something like this

Do you have a cnc machine or looking to buy etc?

Just about any cnc machine with enough rigidity to handle the forces from a tilting saw attachement should do the trick. Since slots are14mm wide i wouldn't rule out a router, its just that you would need a decent router(say 8Kw) to do the job in one pass with a 12mm bit and if you need square edges a manual corner chisel will do a quick job of it.

Either way you would definitely need a heavy duty and solid machine to handle all the forces without tearing the machine apart.

Thanks Daniel - not looking to buy a CNC, just wanting to know what capabilities to ask for when doing the out-sourcing research.

Hi Gavin

Whilst a dado may be fairly slow, the same would not be said of twin blades mounted on the same arbor with a spacer between them. There is no need to turn the whole of the cutout into sawdust.

A photo of what you are trying to achieve would be helpful as well.

Gavin, no worries then.

Just thinking, if your panels are just rectangular with no extra work and just the angled slots, then take a quick drive south to GK Engineering. The guy there, Bob, is really nice and has a 5 axis waterjet machine that would handle a full sheet. I've used him plenty and have recommend him alot. As the waterjet is so high pressured it will not soak into the wood and with the tilting head he could do it all with square corners plus thin kerf means minimal material wastage. You would have to speak to him about how he likes the drawings to show the angled slots so they program it right but would be worth a shot. Local and his prices are quite competitive.

Nice pickup Bob, Would also reduce the amount of wear on the motor as well as there is less resistance.

Gavin,

Any luck with your shelving work?
