RESUMO

This work presents a study of the diamond blade dicing of piezoceramic slabs to fabricate piezocomposites by dicing and fill process. A diamond blade dicing machine is designed according the needs of the dicing and fill process to produce piezocomposites which requires dicing with diamond blades as thin as 30µm. The dicing machine has a high speed (up to 60.000 rpm) spindle with aerostatic bearings for 2 inches diameter dicing blades. The piezocomposites with frequency up to 10 MHz are the main part of ultrasonic transducers for medical and industrial applications. The study of thin diamond blade dicing is based in the kinematic model for grinding and experimental work. The results of diamond blade dicing of PZT piezoceramic slabs are analysed with an optical microscope and the measurements of superficial cracks are presented.
