Cutting Chloroplast

Postby DEdwards » Fri Jul 21, 2017 3:29 pm

We are cutting out arrows from chloroplast, and this is the first time we are using the router for something like this. I have been doing some research and so far I have stumbled across very little.

My question is, what would be the best bit to use for routing such a thing piece of material? Along with that what type of speeds and feeds would you try to use on something like this.

I am sorry if this is a dumb question but I am stumped. Thank you for any information.

Use single O flutes designed for soft plastic. you will have to play with rpm and feedrates to get rid of fuzzies

Another way is to use a drag knife. Depends if you're doing enough to make the investment in one worthwhile and what thickness of coroplast you're using.

I've always had issues with fuzzies when cutting coroplast. I've tried straight flute "o" bits and down-shear "o" bits, but I can never seam to get rid of the "fuzzies" problem.
Gary, what kind of speed and feeds are you using to overcome this issue?

John...
I'm not. But I can remember helping out a sign shop on a service call a few years back to get his dialed in.

Just like any other material, start at 50, plan on going up to 300. Rpm between 8000 and 18000. There will be a combo that works best
