Problems solved by technology

The machines used are therefore of a correspondingly complex design and the sawing wire is subjected to high mechanical loads due to the necessary guide and tensioning rollers, which shortens the service life of the sawing wire used and thus increases costs accordingly

Embodiment Construction

[0043] exist figure 1 A schematic block diagram of a first embodiment of a system 18 for separating a plurality of ceramic components 11 - 15 from a ceramic component block 1 is shown in . The system 18 has a saw frame 2 and an actuator 19 . The saw frame 2 has a plurality of parallel wire segments 21 - 26 clamped in the frame 3 . The actuator 19 drives the saw frame 2 in order to saw the component block 1 into a plurality of components 11-15 or to move the saw frame 2. here, figure 1 The reference sign R in shows the sawing direction. Without limiting the generality, in figure 1 Six line segments 21-26 are shown in . However, the number of segments 21-26 clamped in block 3 may be any number. In addition, in figure 1 Also shown is a component block 1 or green block having a cuboid shape. This shape of the green block or component block is also only exemplary, any other shape is conceivable.

[0044] The frame 3 preferably has two opposing wire tensioners 41-46; 51-56 ...

Abstract

The invention relates to a method for detaching a plurality of ceramic components (11-15) from a ceramic component block (1), said method comprising the following steps: providing the component block(1); mounting a plurality of parallel wire segments (21-26) in a frame (3) to form a saw frame (2); and sawing the provided component block (1) into the plurality of components (11-15) using the saw frame (2).

Description

technical field [0001] The present invention relates to methods and systems for separating a plurality of ceramic components from a component block. Background technique [0002] The ceramic component is, for example, a piezoelectric stack (Piezo-Stack) used in the manufacture of piezoelectric actuators. [0003] Piezoelectric actuators usually consist of multiple piezoceramic discs. A piezoelectric ceramic is a material that expands due to the piezoelectric effect when a voltage is applied. Such piezoceramics form the basis for piezoelectric actuators, which achieve a travel path of a few micrometers when an electric voltage is applied. [0004] Piezoelectric ceramics are used, for example, as substrates for piezoelectric actuators which are used in particular in the automotive sector, for example as electromagnetic transducers in common rail injection systems for internal combustion engines. [0005] The individual piezoelectric ceramics described above are equipped wit...
