Quartz Crystal Production - Lapping / Grinding
Polishing and contouring are the final mechanical steps involved in the production of quartz blanks. The rounded blanks are separated and individually processed to their final grade of surface finish and frequency. The polishing machine pictured represents the finest level of surfacing and is able to produce quartz blanks up to 35 MHz on the fundamental mode. Crystals with frequencies below 20 MHz operating on the third or fifth overtone response often require one of their surfaces to be polished into a concave shape to enhance the Q of the desired mode of operation. This contouring operation concentrates the mode shape of the vibration into the center of the quartz blank reducing edge effects.
