Antique Radio Forums • View topic - FT-243 Crystal Grinding?
The secret to moving the frequency of a crystal very far is that the grinding must be done in a uniform manner. My old friend, NG7A (sk) used to move crystals in the 5mc range to the 7mc range and they all worked just fine. But he had his micrometers on the piece of quartz very often.

If the crystal gets "sluggish" or even quits oscillating completely, grinding the edge of the blank, at an angle, often gets the crystal working again. Plated crystals, i.e. HC6/U types, can have the frequency moved a little bit. Of course, one has to un-solder the the main housing from the base which contains the actual crystal.
How Are Quartz Crystals Cut and Polished? | Our Pastimes
Grinding, Sanding and Lapping. The quartz crystal is then polished by grinding and sanding. The grinding wheel is dotted with very coarse bumps made out of an extremely hard material such as silicon carbide. It spins rapidly and is pushed against the quartz to slowly wear it away into a chosen shape. Once the gem cutter creates a rough shape by ...
