Description

technical field

[0001] The invention relates to a ceramic hole processing device, in particular to a multi-frequency ultrasonic processing device for engineering ceramics. Background technique

[0002] With the increasing application of engineering ceramics in aerospace, electronics, automobiles and other fields, the requirements for the processing methods of these materials are getting higher and higher. However, due to the hard and brittle characteristics of engineering ceramic materials, it is usually difficult to process by traditional machining methods, and most ceramics have poor electrical conductivity, thus limiting the use of EDM. In view of this, ceramic materials are greatly limited in processing.

[0003] At present, the methods of ceramic processing mainly include mechanical processing, laser processing and ultrasonic processing, among which ultrasonic processing is widely used. Ultrasonic machining is mainly to convert the oscillation signal generated by the ...
