Is it possible to cut the ferrite magnet without losing its magnetism?

Magnets are widely used and have many different applications. However, for some purposes, some customers may have the idea of cutting, drilling or welding ferrite magnets to achieve the desired shape.

Ideally, it is possible, but it is extremely difficult to implement it correctly. If you are not careful, the magnet will implode rapidly or lose the magnetic field. Generally speaking, it is better to customize the magnet from the magnet manufacturer rather than operate it at will.

The ferrite magnet itself can be processed, but because it is fragile, sudden impact on the magnet and incorrect treatment may lead to its rapid fracture.

Ferrite magnets can be cut, but the possibility of losing magnetism is very high

As mentioned earlier, cutting ferrite magnets is usually unwise because of the high possibility of losing magnetism. In fact, neodymium magnets and ferrite magnets are processed, cut or drilled before magnetization. If ferrite and neodymium magnets must be drilled or cut, suitable diamond tools should be used and equipped with a cooling system.

Because ferrite is a brittle material, it is not recommended to cut it with ordinary tools (such as drill bit) because ferrite may overheat and produce a large amount of highly flammable dust. And doing so will often demagnetize the magnet.

How to cut ferrite magnets without losing magnetism?

First, use work gloves to avoid contact with debris, which can be dangerous in contact with the skin. The cutting line must be marked on the magnet to avoid deviation from the required cutting.

Use a protective mask for the nose and mouth because cutting the magnet will produce dust left in the air.

Fix the magnet with screws to prevent it from moving, which is conducive to maintaining its magnetism. Excessive vibration will cause the magnet to lose magnetic electrons, thereby reducing or losing its magnetism. By controlling the vibration, the magnetization loss can be avoided.

You can use a saw to cut the magnet along the cutting line, but you can also use a gold-plated diamond tool on the lathe and press it into place. Next, start the device. As the lathe rotates, place it on the mark on the magnet and press it down at the same time. Try not to exert great pressure on the lathe, otherwise the tool will be bent.

You can also use a chisel on the cutting line on the magnet. Hold it in one hand and hit the top of the chisel with a hammer. If the cutting fails, this will split the magnet in two. But remember, this will be your last choice, because it is most likely to destroy the magnetism of the magnet.
