In recent years, with the rapid development of new energy, electronics and high-end manufacturing, the demand for high-performance magnetic materials (such as NdFeB permanent magnets) has surged. Laser cutting technology has become a key technology in the field of magnetic material manufacturing due to its high precision, low thermal impact and efficient processing, and has promoted the industry's technological upgrading and cost optimization.

 

Magnetic materials such as NdFeB have extremely high requirements for processing accuracy, and traditional mechanical cutting can easily cause material cracking or magnetic performance attenuation. The magnetic material laser cutting machine achieves micron-level accuracy by focusing high-energy beams. The incision width can be controlled at 0.1-0.3mm, and the heat-affected zone is extremely small, avoiding the destruction of the material grain structure, thereby ensuring the stability and magnetic energy product of the magnet.

 

Magnetic materials often need to be processed into complex shapes to meet the needs of different equipment. The magnetic material laser cutting machine can flexibly program the path to achieve precision processing of special-shaped holes, micropores and three-dimensional structures, while supporting multi-thickness cutting from thin plates to thick plates. In addition, laser cutting machines have excellent adaptability to hard and brittle materials (such as sintered NdFeB) and non-metallic magnetic composite materials, avoiding the limitations of traditional processes.

 

Laser cutting machines have a high degree of automation and can operate continuously, greatly shortening the production cycle. For example, in the nesting processing of magnetic materials, laser cutting machines reduce scraps by optimizing material arrangement, and increase material utilization by 15%-30%. Non-contact processing also avoids tool wear and oil pollution, which is in line with the trend of green manufacturing.

 

The application of laser cutting machines not only reduces the manufacturing cost of magnetic components, but also promotes their innovative application in high-end fields. For example, the mass production of high-precision magnets in new energy vehicle drive motors and the fine processing of magnetic films in miniaturized electronic devices all rely on the efficient support of laser technology.
