Milling / Grinding Stone Practical Machinist
#0183;#32;Currently my thoughts are to mount the stone in the bottom of a fixture with pan built in. Fill with water, and allow a diamond burr to very slowly feed into the part. (Ye, I know mixing rocks, CNC mills, and water is probably not a great idea!) Fortunatley the part is a thin sheet of material lt;1/8quot; thick, so a single slow pass should work.
