If your cutting any thin sections clean through, the Corian can warp.
I make harmonicas from Corian and some colors are unusable.
I know that sounds weird but darker colors get allot hotter than light colors.
I cut it at 4 inches per min using a 2hp Hitachi router, 2 flute endmill.
I am also using an Exair cold air gun. It helps allot but some colors still warp.
I tried running some through a planer ( scary) and it warped the h@ll out of it.
Beautiful finish though. |
