Hello,

I know this topic has been discussed here before. I am looking for a solution to cut carbon fiber sheets. So far I got perfect results only outsourcing to a water-jet cutter but it is expensive to use on a regular basis. I tried driving a dremel with different discs (diamond and for plastic PVC) on a linear  guide, the result is great but not perfect. There is still a little bit of burr left on the edge or I guess the resin coating is slightly burnt.. it is hard to tell but it is not perfect. Any hints or ideas ?

yes, these are exactly the disc dimension I use. I guess the machine will work too. I am using one where the motor slides on a rail above, so the carbon plate can't get scratched from sliding on a metal surface. You may have to improvise to mount the disc. I used a small ring of a worn down angle grinder disc as a chim, otherwise the disc would have been too narrow.
