Official Luthiers Forum!

hey there,

i have been doing some inlays for people on the CNC lately and just wanted to share
thats for a rosette, its one of 13 pieces in the rosette



this one is going between 11th and 12th on an existing classical guitar, it is the symbol of the subud spritual movement

Looks like you got the hang of the CNC Paddy!

Really nice work bud!

Paddy That is really nice. CNC is just a step away from magic. When I lived in California, a friend had a large laser cutter that worked off of a CNC setup. I was amazed at some of the intricate jobs that he would do.

Nice work Paddy. Looks like you're having fun with your CNC.

Al[/QUOTE] Laser cutters are great too! I've done a bunch of wood and plexi templates with one. Wish they could cut shell though Paddy would you share photos of the actual CNC?

Wow that is something else, I did not know cnc could get that small.
so shell can't not be cut by a laser cutter? shame I was thinking about getting my inlays done by a woman who lasers my pickups.

I'm pretty sure it can be water jetted! I've never seen anybody do it, but if you can cut ceramic you can cut shell!

yep CNC can go that small,

only trouble is you have to use .010 carbide cutters, and they are like $35 a piece, they break without warning, and it is slow, that symbol took 4.5hrs to cut, as the feed rate is only 1" per minute, and is depth pass is 0.15mm, but i really get a kick out of it!!

i tried water jet, and it is ok for fairly simple shapes, but for very fine stuff it just blows the shell to pieces

Paddy I have got to come and visit you!

Paddy, do you have a high-speed spindle?

Only badly."

my current spindle is 24k, i am trying to get an air turbine spindle made with a 90k speed, then i can cut the machining time a lot, especially with small cutters

Never thought of that! Did you try and glue it to something substantial before cutting and removing, after the cut, of course!

We tried and tried but it would not work.. I can cut plexi, wood and engrave glass or metal but cant cut shell. It dispurses the heat or something and just makes a big mess. Feel free to try it though.. Maybe your laser guy knows something mine doesn't. I gave up after I looked around and noticed all the big inlay guys use CNC with those little bits.. Figured if they could get away with a laser instead of dealing with the cnc and all those bits they would have.Jason38796.0029282407

Lasers don't like highly reflective surfaces and maybe the bigger issue here is that different frequencies couple or don't couple with materials.
For example I have a 100W laser at 1064nm and can't cut 1/16 plastic of alsmost any kind. Go figure, but it's a coupling issue.
So, some laser would probably be able to cut it.
