Abstract

The invention discloses a ferrite composite material laser cutting method which comprises the following steps: step 1, mounting a ferrite composite material, and preferentially cutting a protective layer; 2, emitting and focusing laser to obtain a focused light beam, and controlling the focused light beam to form a focus on the surface of the ferrite composite material; and thirdly, the focused light beam is controlled to move along a set track, and intermittent repeated scanning is conducted on the ferrite composite till cutting is completed. The defect that the ferrite composite material in a complex shape is prone to brittle damage in the cutting process is overcome, the focused light beam cuts the ferrite composite material through fusion, the protective layer is cut preferentially, the protective layer can relieve the heat accumulation process and play a role in protecting the ferrite layer, the intermittent repeated scanning cutting heat affected zone is small, and the cutting efficiency is high. And brittle damage can be further prevented, and the cutting effect is better.

Description

technical field [0001] The invention belongs to the technical field of laser processing, and in particular relates to a laser cutting method for ferrite composite materials. Background technique [0002] With the vigorous development of communication technology, various wireless devices are widely used in various terminal devices, but there are serious interference phenomena among various signals. The use of electromagnetic shielding materials can significantly reduce this interference phenomenon and ensure the stability and safety of the equipment. New ferrite composite materials are widely used due to their small size and stable shielding. However, in the process of use, high-quality cutting of new ferrite composite materials is still required to meet the needs of customized placement of various terminal equipment. [0003] The traditional cutting method is mechanical cutting, which adopts die cutting and punching, which has low processing efficiency and is easy to break...
