Group: Forum Members Posts: 3, Visits: 39	I've been looking around for a CNC cutter/laser to cut out certain standard shapes. We mainly use xpreg XC 110 and XC 130 (unidirectional). I came across the CNC-step machines. On their site it says they can cut prepreg with an oscillating knive, but in reality it turns out there are some issues. Does anyone know of a system or manufacturer that allows CNC cutting of prepreg materials? Rogier Edited 6 Years Ago by Rogier Claes

PCB cutters work very well for this purpose and are cheap and easily sourced and replaced when they get blunt. What Warren said :-) Cutters MUST be sharp.

Thanks for the quick response, just to be sure, you are also talking about uncured prepreg carbon? Do you have any experience with a certain company/brand? Rogier

You mean something like this? https://www.youtube.com/watch?v=oLw9Pslu1Bw

Yes, but in this case it seems to me there is no protection foil/release film on the material. That leads me to think this is not uncured prepreg. I’ve asked a manufacturer but they said cutting...

It looks like uncured pre preg to me. Not all pre pregs necessarily have the plastic backer or maybe this machine works better without the plastic backer on the material? What you see in that video....

I feel nobody is reading what the OP is actually asking haha. OP, for what it's worth - I have tried an oscillating knife on a 6040 CNC router to cut uncured XC110. It was a disaster. The material.....

Yeah, good point :-)

My work uses ultrasonic blades to cut prepreg even then after a while they need to changed or cleaned from the resin
