12477Re: working bronze
- May 1, 2005I've machined silicon bronze shafts for a boating buddy and found it
fun. It makes very pretty ribbony swarf. IT's tough, similar to
SS. For slitting saws just use any speed/feed table and use the
diameter of the saw. With a 3" saw, you'll end up pretty slow. HSS
should work fine, especially with coolant. If you don't have flood
coolant, squirt it frequently with some light cutting oil. I often
run slitting saws very slowly so that I can just squirt coolant onto
the top of the blade and let centrifugal force feed it in.
