Ferrous materials and tools can become magnetised due to a number of causes, such as during sanding, grinding,
polishing, welding, punching or cutting operations. However, this may also occur de to direct contact with (magnetic equip-ment), or even simply as a result of friction during processing. Whatever the cause, the result is the same: magnetised products that stick to one another and attract dust and swarf.
Besides demagnetising equipment Goudsmit also manufactures lifting magnets. For more information: please click here:

Even when residual fields are small, magnetization in a machine shop can cause problems with mechanical equipment. For example, ferrous grit attracted by magnetized tools and dies can cause excessive wear, and magnetized parts in assembly operations may hang up in feed chutes and magazines.
The only answer to such problems is demagnetization, which is accomplished by subjecting a magnetized part to a strong reversing magnetic field to disarrange the magnetic particles so that the required residual magnetic field is obtained.
Aperature Type Demagnetizer
Walker demagnetizers are designed to negate the effect of residual buildup with units matched to the size and material of the workpiece and engineered with control circuits that can effectively erase the residual fields. Walker has the only compensated units available that provide increasing field strength with increases in workpiece volume. |

Bussi Elettronica Industriale has manufactured patented Electronic Demagnetizers since 1969.
The high level of specialization and the continuous search for new solutions, guarantees top quality products and service. Demagnetising a metal part efficiently means contributing to the overall quality of the finished product.
The D-F series demagnetizers for FlexLink and the D-R series for Rotzinger fit into the conveyor systems of the two brands. These models consist of an electronic cabinet with support and a demagnetizing coil.
The metal parts, usually rings and bearings, lie on the conveyer chain. The chain brings them into the coil and, when the piece is in the middle of the coil, the unit releases a capacity discharge without stopping the line. These models are also suited for all types of metal parts, of different dimensions and shapes.
The performances guaranteed by Bussi demagnetizers®, include: Minimum residual magnetism, Complete reliability, High productivity, Easy Motion with no magnetic impediment, Minimum power consumption, easy Adaptability to client’s production lines and customisation to apply Bussi technology to all demands – www.bussi.it

The DM-CB can operate in and off line. Suitable for tight spaces, it guarantees demagnetization of a wide range of piece sizes. It consists of an electric cabinet and, separately, a conveyor belt with integrated coil and relative support.
Versatile: A modular device that can easily be incorporated in the line without further adaptation costs.
Compact: the size of the conveyor belt is reduced to the minimum.
Simple: it can be adapted to every industrial layout. |

The model RDU3-A, is a fully automatic unit consisting of an electronic demagnetizing and handling unit with a conveyor belt. It has also a compressed air system for top coil height regulation and applying a load to the rings during demagnetization.
The RDU3-A has been created to demagnetize large bearing rings: Diameters 120 to 420; Height 20 to 200. The versatile working of this machine guarantees complete adaptability to a wide-range of applications.
Functioning sequence: The ring is loaded onto the conveyor belt, it is detected and measured, transported to the centre of the demagnetizing coils. At this stage, the conveyor belt stops, the coil descends pneumatically while a load is applied to the ring to be demagnetized. The coil rises and an enabling signal are given when a new ring is delivered. The conveyor belt starts again and the demagnetized ring is unloaded.

Demagnetizing a metal part efficiently, means to contribute to the overall quality of the finished product.
The D-V series demagnetisers are made to demagnetize all metal parts, usually rings and rollers, inside rolling channels. These models consist of an electronic cabinet with support and a demagnetizing coil.
The channel brings them into the coil and when the piece is in the middle of the coil, the unit releases a capacity discharge. The demagnetization coils are designed to be easily adapted to rolling channels.
