METHOD FOR MANUFACTURING OF FLAT PIEZOCERAMIC ITEMS AND DEVICE FOR ITS REALISATION Russian patent published in 2011 - IPC H01L41/24 H04R17/00 B23K26/40 

FIELD: electricity.

SUBSTANCE: method includes fixation of polarised flat piezoceramic plate and cutting with laser beam. Fixation is carried out in cuvette on surface of cooling liquid or on gasket from porous material impregnated with cooling liquid, amount of which is maintained at the level of gasket. Cutting is done by focused interrupting laser beam along circuit of cut item in one or more stages with simultaneous cooling of cutting circuit. Device comprises laser, control system, mechanisms of optical elements moving, technological table with cuvette of soft magnetic material installed on it and partially filled with water, on bottom of which there is a porous material intended to locate cut flat piezoceramic plate, and fixation device of specified plate.

EFFECT: simplified technology of manufacturing of flat piezoceramic items of various configuration and dimensions and improvement of their properties and parametres due to provision of usage of whole surface of piezoelement.
