Problems solved by technology
[0003] Flexible ferrite electromagnetic interference suppression components have various specifications, sizes, shapes and characteristics, so the requirements for their processing technology are getting higher and higher. Flexible ferrite needs to be cut into different shapes according to the requirements of the products to be installed. Shape, traditional machining methods such as die-cutting of metal tools and die-cutting of metal molds, the processed flexible ferrite products have poor edge alignment and precipitation of granular substances, which cannot meet the processing requirements of high-quality and high-precision products

Abstract
The invention discloses a laser cutting method for ferrite and a laser cutting device. The method includes the steps that the height and the focus position of a cutting head are adjusted, and laser machining parameters and drawing files are set; the ferrite is cut by using a first laser; and a second laser is used for finely trimming the edge contour of the ferrite subjected to cutting machining,and the high-quality and high-precision cut ferrite with the tidy edge can be obtained.
Description
technical field [0001] The invention relates to the field of laser technology, in particular to a ferrite laser cutting method and laser cutting equipment. Background technique [0002] Flexible ferrite is a composite oxide composed of iron and one or more other metals. It can also be understood as a ferromagnetic metal oxide. In terms of electrical properties, the resistivity of flexible ferrite is higher than that of metal , Alloy magnetic materials are much larger, and have higher dielectric properties. At the same time, the magnetic properties of flexible ferrite are also characterized by high magnetic permeability at high frequencies, and are widely used in electromagnetic anti-interference field, such as Near Field Communication (NFC) technology. [0003] Flexible ferrite electromagnetic interference suppression components have various specifications, sizes, shapes and characteristics, so the requirements for their processing technology are getting higher and higher. ...
