FIELD: electrical and radio engineering; manufacturing components for quartz-crystal resonators.
SUBSTANCE: proposed method for manufacturing quartz-crystal components with their surfaces finished to high-degree classes up to class 14 involves their double-ended grinding with micro-powders including sequential reduction of abrasive material grain size to M5, double-ended polishing with cerium dioxide on substrates of sheet polymer, such as polyurethane, and post-grinding deep chemical etching of quartz-crystal components in acid etching solution based on hydrochloric acid and butanol through depth exceeding that of grinding-destroyed layer prior to polishing procedure.
EFFECT: enhanced quality of component surface treatment, reduced manufacturing time and labor consumption.
