surface

I recently purchased a Grizzly G3155 surface grinder that did not come "ready to use". I need a hub for the grinding wheels, a wheel dresser, and some wheels. I may also need a wheel balancer. I do not know a lot about grinding. Starting off, do I want one rough wheel and one finishing wheel...

Have done few tests last saturday. The old and slow shear tool was the winner. (at least for my conditions) IF the diameter was bigger, than the indexable Sandvik insert could have a better result. [Edit] Have done a research on materials too...
