Problems solved by technology

This distance of a few millimeters is of course too small for the required cutting width of piezo stacks or piezo stacks, so the wire saws known from semiconductor technology cannot be used for separating ceramic components such as piezo stacks.

Abstract

The invention relates to a wire saw (S) for separating a plurality of ceramic components (11-16) from a ceramic component block (1), comprising a roller system (2), said roller system comprising a plurality of deflecting rollers (3-5) guiding a wire (6) to form a wire harp (7), wherein at least one of the deflecting rollers (3) is divided into separate discs (31-36) guiding a single wire winding (61-66) of the wire (6) and being inclined at an adjustable angle (a) of less than 90 DEG to an axle (A) connecting the centers (M1-M6) of the discs (31-36).

Description

technical field [0001] The present invention relates to a wire saw for dividing a plurality of ceramic elements from a ceramic element block, and also relates to a method for dividing a plurality of ceramic elements from a ceramic element block. Background technique [0002] Ceramic elements are, for example, piezoelectric laminates or piezoelectric stacks, which are used in the production of piezoelectric actuators. [0003] Piezoelectric actuators usually consist of multiple piezoceramic discs. Piezoelectric ceramics are materials that elongate when a voltage is applied due to the piezoelectric effect. This piezoceramic forms the basis of piezoelectric actuators, which achieve a travel distance of a few micrometers when an electric voltage is applied. Piezoelectric ceramics have electric dipole moments, which each have a preferential direction in the Weiss field regions, which are separated from each other. In the unpolarized ground state of piezoelectric ceramics, the ...
