How to Grind Down Quartz Countertops
Step 3: Start Grinding with 50 Grit. Attach a 50 grit diamond abrasive pad to your grinder. Hold the grinder flat at a 5-10 degree angle and gently grind the marked areas using sweeping motions from multiple directions. Apply light pressure and keep the pad constantly moving. Be patient and make several passes over damaged spots.

Crystal grinding: When electronics were REALLY hands-on
In the 30's, the ham bought a crystal blank and ground it down to the target frequency using a slurry of grinding powder and water on a glass plate making little figure 8's. Grit size was important and especially maintaining flatness. Typically, you only trusted yourself to grind one side so at least one side would stay flat.

The Significance of Fine Grinding
grinding quartz, Deane K. Smith explains that researchers have consistently found a correlation between the particle size of the ground products and their degree of crystallinity (as measured by the x-ray diffraction response).

Can I use a sander or grinder to polish quartz countertop …
I think a significant difference between a regular angle grinder and a polisher is the speed. The tool I mentioned earlier can vary speed between 2000 and 4000 rpm, while single speed angle grinders run at a constant, typically higher RPM in the 5000-10000 range. If your angle grinder has variable speed, it might be OK.
