Key Features
300W QCW Fiber Laser
High peak power and pulsed energy delivery provide efficient material removal while allowing the thermal input to be controlled through optimized laser parameters.
Optimized for 1mm NdFeB
Designed around the processing requirements of approximately 1mm NdFeB magnet materials, with parameters optimized according to material grade, geometry and edge-quality requirements.
Controlled Heat Input
Pulse width, frequency, duty cycle, processing speed and other parameters can be adjusted to achieve a suitable balance between cutting efficiency and thermal control.
Non-Contact Processing
Laser cutting does not require physical cutting tools, reducing mechanical cutting forces, tool wear and contact-related damage.
Complex Contour Cutting
CAD-based laser paths allow flexible processing of customized magnet geometries, including arcs, rings, segments, slots and irregular profiles.
High Material Utilization
The concentrated laser beam enables narrow cutting paths, helping reduce material loss when processing high-value NdFeB materials.
Why Use Laser Cutting for NdFeB Magnets?
NdFeB is a high-performance permanent magnet material widely used in motors, generators, electronic products, and precision magnetic components. However, its hardness and brittleness make traditional machining extremely challenging, especially when processing small, thin, or complex-shaped parts. This laser cutting machine can also be used for the precision machining of other materials, such as silicon steel sheets, copper-aluminum substrates, PCB substrates, and tungsten steel sheets.Reduced Mechanical Stress
Flexible Geometry Processing
The laser can follow programmed CAD paths, making it suitable for:
· Arc-shaped magnets
· Ring magnets
· Segment magnets
· Customized magnet profiles
· Slots
· Holes
· Internal contours
· Small magnetic components
Suitable for Customized Production
The digital nature of laser processing makes it convenient to switch between different magnet shapes and designs without changing conventional cutting tools.
NdFeB Laser Cutting Process
The typical processing workflow includes:
01. CAD Design
Import the required magnet geometry or customized cutting profile into the control system.
02. Workpiece Positioning
The NdFeB material is fixed on the worktable using a suitable fixture.
03. CCD Vision Positioning
An optional CCD vision system can identify the workpiece position and compensate for positioning deviations before processing.
04. QCW Laser Cutting
The 300W QCW fiber laser follows the programmed path to cut the NdFeB material.
05. Assist Gas
Assist gas helps remove molten material from the cutting zone and can help improve cutting stability.
06. Cleaning
Depending on the application, the processed components can undergo cleaning or additional finishing.
07. Inspection
Dimensional, visual and, when required, magnetic-performance inspection can be performed after processing.

FAQ
1. What thickness of NdFeB can this machine cut?
This system is currently positioned for approximately 1mm NdFeB magnet materials. Actual cutting capability depends on the material grade, geometry, coating, required cutting quality and optimized process parameters.
2. Will laser cutting affect the magnetic properties of NdFeB?
Laser processing introduces localized heat, so thermal input should be carefully controlled. For applications with strict magnetic-performance requirements, magnetic properties should be tested after laser processing to verify the actual effect.
3. Can it cut customized NdFeB magnet shapes?
Yes. CAD-based laser processing allows customized contours to be programmed directly. Typical applications include arc magnets, ring magnets, segment magnets, irregular profiles, slots and holes.
4. Why use a QCW laser for NdFeB?
A QCW laser provides high peak power while allowing the average heat input to be controlled through pulse parameters. This provides greater flexibility when balancing cutting efficiency and thermal impact.
5. Can you test our NdFeB samples before purchasing?
