Cestriom demagnetizing products
Increased residual magnetism in ferromagnetic components
often harms industrial manufacturing and testing processes, as
well as the function of these components. Different processes
are particularly relevant in the US industry which are affected by
residual magnetism as welding, machining, punching, cleaning,
and coating. For example, the welding process presents issues
such as magnetic arc blow effects and beam deflections in EB
welding, the machining process presents magnetic adhesion of
chips, punching process presents issues as magnetic adhesion
of the punching waste in the waste holes and thus tool breakage
under certain circumstances, cleaning process presents issues
as magnetic adhesion of particles, and coating process presents
some issues as irregular layer structure and poorly adhering
layers.
When influencing the function of components, the following
examples should be mentioned, among others:
*
particles/chips)
*
Hydraulic systems (trouble: magnetic adhesion of particles
and chips at critical points and/or damage to seals due to
Noise development and reduced service life of roller
bearings (trouble: magnetic build-up of abrasion)
*
results of the sensor system)
*
Negative influences on the function of magnetostrictive
sensors (trouble: magnetic spots influence the measurement
Minimization of the risk of failure of large rotating
equipment (trouble: increased residual magnetism in the rotor or
housing can lead to self-induced currents and total failure of the
machine)
Solving these above-mentioned issues related to residual
magnetism in an industrial environment requires understanding

the customer's process and needs ability to develop customized
demagnetizing systems. The process parameters of the demagnetizing
systems usually should be adapted to the customer
situation. In this complex environment, Cestriom and Salvador
Consultant offer the necessary know-how for the US industry.
How can the tool components be magnetized?
Machining, drilling: Direct contact between cutting insert or drill
and production part. This means that residual magnetism can
potentially be transferred via the contact surface.
Grinding: The risk of magnetization of the parts directly through
the grinding process is rather low. During grinding the parts are
often held in place with magnetic clamping devices (magnetic
chucks). Due to the direct contact between the component and
the magnetic chuck, a relatively high residual magnetism usually
remains in the material. This is the case even if the magnetic
chuck has an integrated demagnetizing function.
EDM: During erosion, strong pulsed currents flow between the
electrode and the component. This current flow in turn generates
its magnetic field for physical reasons, which magnetizes the
eroded areas in the material.
Coating: For galvanic coatings, such as chrome plating, strong
direct currents are necessary for the process. These direct currents
flow at least partially through the components to be coated
and can magnetize them.
Mounting of stamping tools: Direct contact between magnetized
tools (for example screwdriver tip) and the stamping tool surface
