Below is a photo of a 46 K AO grinding wheel on my cylindrical grinder. It's 25mm (1") wide.
I ground about 0.2mm (0.008") off the diameter of a good-sized piece of 4140 PH and after a light dress the wheel looks like this:
You can see that there's a lot of bits embedded in the wheel. My question: do I need to dress more off the wheel, to get rid of the steel that's embedded there? I have the impression that the finish I am getting now is not as good as normally, and am wondering if that's why.
