O que é um mandril magnético eletropermanente?
Um mandril magnético eletropermanente é uma ferramenta feita de materiais magnéticos permanentes que utiliza pulsos elétricos para alterar o estado do campo magnético. Ele é usado principalmente para prender e fixar trabalhos em vários campos de fabricação, processamento e inspeção.
A tecnologia principal de um mandril magnético eletropermanente é sua capacidade de alterar instantaneamente a polaridade do campo magnético por meio do controle de pulsos de corrente externa, permitindo a abertura e o fechamento rápidos do mandril, aumentando significativamente a eficiência do trabalho e a conveniência operacional. Isso é particularmente vantajoso em situações que exigem fixação e liberação frequentes de peças de trabalho, especialmente em processos que necessitam de posicionamento de alta precisão e alta capacidade de carga.

Electro Permanent Magnetic Chuck Working Principle
An electro permanent magnetic chuck is a device that combines the features of permanent magnets and electromagnets. It’s made up of permanent magnets and electromagnetic coils. Without power, the permanent magnets give the chuck some holding force to keep the workpiece in place.
To clamp or release the workpiece, you energize the electromagnetic coil. When powered, the coil creates a magnetic field that interacts with the permanent magnets. By controlling the current’s direction and strength, you can change the electromagnetic field’s direction and intensity.
If the current makes the electromagnetic field go in the same direction as the permanent magnets, the magnetic force increases, clamping the workpiece tighter. If the current makes the field go in the opposite direction, it cancels out the permanent magnets’ field, reducing the magnetic force and releasing the workpiece.
How Electro Permanent Magnetic Chuck Works?
- Apply an excitation current to the solenoid coil for 0.1 to 0.5 seconds.
- The pole of the AlNiCo magnet is reversed. The neodymium and AlNiCo magnets become monopolar.
- Magnetic lines of force concentrate on the surface of the magnetic poles, clamping workpiece securely.
- Apply another current to the solenoid coil for 0.1 to 0.5 seconds.
- The pole of the AlNiCo magnet is reversed again.
- The neodymium and AlNiCo magnets stop emitting magnetic flux from the surface of the magnet core. This unclamps the workpiece, allowing it to be easily removed.
Yes, by using specially designed floating magnetic blocks, we can adapt to uneven workpiece surfaces and minimize deformation. You can trust our solution for precision machining.
Absolutely, as long as the required holding force is within the specified maximum capacities of the chuck. Even if the workpiece is larger than the chuck area, secure clamping is achievable.
Theoretically, they can achieve up to 16 kg per square centimeter.
For medium- and low-carbon steels, residual magnetism is negligible. High-carbon steels may retain some magnetism, but we can incorporate demagnetization procedures to meet specific requirements.
Our chucks have magnetic poles spaced at 50×50 or 70×70 mm with standard penetration depths of 13 mm and 18 mm, respectively. As long as the workpiece thickness exceeds these depths, there should be no impact on the tools. Even with thinner workpieces, the magnetic field strength is low and unlikely to magnetize the tools. However, extremely thin workpieces might cause debris flow issues leading to tool damage or breakage.
Yes, we can customize chucks based on the specific dimensions and shapes of your workpieces. By providing us with detailed drawings of the mounting surfaces, we can design a tailored solution to meet your manufacturing needs.
