ABSTRACT:
A method for batch-contouring crystal plates for frequency adjustment is disclosed. A plurality of plates is secured to a compliant sheet and the sheet is attached to an applicator surface which includes a resilient pad. The plates are then abraded against another surface to produce contours on all the plates. The resilient pad provides spring loading to insure uniform pressure on all the plates.
