splintering plywood

Postby john jurkowski » Wed, Dec 30 2015, 2:43PM

HELP!!
I have a CS45 and I am having an issue with splintering when I am cutting dados with .25" compression cutter in .5" prefinished maple plywood. I currently have it running at the feed and speed that the machine was set up with when the thermwood tech came out and installed our machine, which is 19,000 rpm and 700ipm. now I am confident that this is a plywood quality issue, as it is not consistent. NOTE this is using a brand new cutter, so I know it is not dull. can anyone give me an idea or 2? please and thank you.

are you cutting deep enough to get below the upcut part of the cutter?

yes, I am going down .26" and the up cut flutes are only .18"
I may try a full down spiral em and see how that works for me, thank you
