I've got a repeat job to surface grind some Inconel 718 parts, taking .005-.020" off each. We're grinding because there are hundreds of holes intersecting the surface at odd angles and minimizing burrs is very important. Surface finish and flatness aren't super important; .001" over a 6" square and 32uin or better are both fine.
Currently we're grinding with the general wheel already on the grinder, white aluminum oxide 8" OD x 1" wide, I believe a 46I or O. The cut doesn't throw sparks and the wheel turns dark after a few passes. It doesn't seem to enjoy taking much more than .0015" off at a time with ~.1" WOC.
Is there a more optimal wheel choice for inconel? I was thinking something more friable (softer) with a coarser grit, but have very little experience selecting grinding wheels.
Thanks in advance.
