[NSRCA-discussion] Cutting CF and FG Panels???

[Keith Black]

This doesn't sound like something one would find at the local hardware store. Where can these blades be found?

BTW, what if you have aircraft ply laminated with carbon fiber? I would think in this case one would need a blade with teeth.

  The proper bandsaw blade for composites does not have any teeth on it at all.  The blade consists of a coating of tungsten carbide bits like rough sandpaper grit adhered to the leading edge of the band. The blade cuts by abrasion and will break before it wears out. Any blade with teeth is bad for composites as it will dull and the teeth can grab and delaminate the sustrate or your bond to the honeycomb.

  What is the best blade to use on a band saw? It has 2 speeds, what is the best speed (1,450 / 3,000 rpm)?

  I need to cut down two 12 x 24 panels and would like a clean edge ( 1/8” CF/Nomex/CF panel, and a FG/Nomex/FG panel) .

  Nope, don't use the band saw much….

  Thanks,
