Question
Forum Responses
From contributor A: I think the fuzz has mostly to do with the moisture content. The tear out is most likely just a normal mill issues. You can go to a 10-12 degree hook on your heads to reduce tear out, but chances are that will increase your fuzz. We run soft maple without too many issues. I think the dry climate makes just enough difference that we never have any trouble with fuzz. We run about 25 FPM with 20* hook. We have a little tear out, but still an acceptable run. From contributor J: Dave, right now I'm using hss ground to pattern. The hook angle is 15 deg and the grind angle is 30 deg. The machine is a bridgwood cm 757. The feed rate is 16 - 65 fpm, and I try to run slow on soft maple probably around 20 fpm. If I go too slow, I get slipping, a jerky feed, and stopping, in which case I increase to keep running. 20 fpm would be a good guess. Tpindle rate is 6000 rpms. The maple origin is unknown. The amount of chips - I joint 1/32 on my first btm cutter, which is the face of my product, and I take another 1/32 with my final finish btm cutter, which are both spiral heads.
