Sign Cutting - Metal

[stickman]

I've been looking at a product called Dibond material, by the Alcan Composite company. I'd like to know if anyone has used it and for what purposes.

Thanks, Jay

I have tried cutting .04 gage aluminum with shopbot
using the 1/4" up and downcut bits. They buildup the soft aluminum (like lead) on the bit and the bit breaks
within a few feet. I was told by Onrud that the aluminum is too soft. I'm thinking the the Dibond is not much different.???

Cutting DiBond is much easier to cut than .040 aluminum.
The aluminum on dibond is very thin.

Nope, that's not right about cutting aluminum. With the proper bit it cuts like butter.To get you going I'd suggest you contact Gary Beckwith (www.beckwithdecor.com) and get the proper bits. I personally use the Belin up spiral O Flute at 14000 rpm's but the travel speed depends on the hardness of the aluminum. With the Belin there isn't any need for a coolant and the sides come out polished. I usually order 6063 aluminum.
