Cutting Corian

I have been trying to cut a word art pattern out of a piece of 12mm Corian (like a resin/plastic sheet used in kitchen worktops). I have been using Flying Dutchman blades, FD Polar No 1 which is the listed blade for Corian. I have turned the speed right down but it's still not clearing the cuttings from the cut and the cut is melting closed behind the blade. Has anyone any idea what I'm doing wrong? I have tried medium speed right down to slowest speed all with same effect. Any help will be greatly appreciated.

 

thanks,  Keith

Hi Keith, I have cut quite a bit of Corian.   I have made many trivets from it.   Your choice of blade it the right one.  Two things are critical when cutting plastics, lubrication and saw speed.  I always cover the pattern with packing tape and slow down the saw speed.   I would probably also use a #3 or #5 polar blade.   Try making some cuts in scrap areas until you get the feel for your saw speed and feed rate.

I would just like to say a big thank you to all who replied. The most useful tip was to use clear packing tape on the pattern, I did this and also used a No3 Polar blade and it cut straight through with no melting together behind the blade and nice clean edges to the cuts. Thanks everyone (I will post picture in bragging rights when I have taken one)
