If your grinder has a spindle lock, press it and spin the wheel till it locks in place. Use a wrench to turn the nut counter-clockwise. Pull the wheel and the backer plate, if there is one, off. Replace the backer plate with the concave design facing away from the grinder. Put the new wheel on and re-tighten the nut.
1. Perform a safety check before turning the grinder on. Make sure the grinder is tightly secured to the bench. Check that the tool rest is in place on the grinder. The tool rest is where the metal item will rest as you grind it. The rest should be secured in place so there is a 1/8 inch (3 mm) space between it and the grinding wheel.
The aim of metallographic planar grinding is to remove roughness from the metallographic cutting process and to achieve flatness of the ground surfaces. The abrasive itself depends on the material to be ground.

I typically grind using a diamond stone for three reasons. First, it will never destroy a tool due to overheating (which can happen with electric grinders). Second, I use the diamond stone to fl at-ten the waterstones. And third, the diamond stone is great for touching up my router bits. I use DMT's extra-coarse stone for grinding my
Using your grinder, shape the preformed stone into the cabochon – adding water to the wheel to keep the stone cool and dust to a minimum. Each time the stone dries, stop, and then add more water before starting again. When grinding, use the lower quarter of the wheel to avoid losing grip on the stone. Add the bevels.
