Dicing

Definition

Dicing refers to the process of cutting piezoelectric materials into small, precise pieces or segments, which are crucial for the development and performance of stack actuators. This technique enables manufacturers to create specific shapes and sizes of components that are necessary for effective energy conversion and mechanical movement. By achieving precise dimensions and optimizing material usage, dicing is integral to both actuator design and the fabrication process.
