Most industries across the world utilize the benefits of various
types of electromagnetic and non-electric magnetic chucks for making
functioning and operations easier. It is no more the time when these types of
chucks are only confined to small surface grinders. The equipment is used for
speeding up the production process considerably, where surface grinding is an
important aspect of the operation.
Magnetic chucks are now widely used and fitted for grinding
machines of massive weights that have a wheel drive of 60 h.p. The segmental
grinding wheels present in them are used for heavier cuts.
So now that you have an understanding of what magnetic chucks
are all about, let us have an understanding of the advantages and disadvantages
of the various types -
Permanent Magnetic Chuck
is absolutely no generation of heat in a permanent chuck,
which is responsible for deforming the workpiece or pole plate.
necessity for electrical power, with fewer chances of the danger of
dropping pieces in a power failure.
installation for transfer from one machine to another.
mechanical switching system is comparatively less efficient for automated
of chuck dimension and likely not suitable for heavy workpieces.
of wear and tear of the internal moving parts and magnets, responsible for
shortening the life of the permanent chuck.
function with control units that regulate the magnetic holding force as
well as the demagnetizing cycle.
can be easily removed from the metal piece.
any moving parts inside for less internal wear and tear.
dimensions can be produced for the chuck, allowing the user to meet
specific requirements of the workpiece size.
a strong and reliable clamping force for pieces as well.
of a constant power supply with a backup power supply for safety reasons.
chances of accidents because of a power failure that can release any part.
power produces heat that can cause distortion of the parts, affecting the
functioning and accuracy of the machine.
Permanent Electromagnetic Chuck
electromagnetic chuck requires power just for
magnetization and demagnetization.
not have any moving part inside, with no internal wear and tear.
gives full access to the five sides of a mold that makes it the ideal
choice for multi-side machining.
of automated use with the operation from a control unit.
heat generation with less threat to machine accuracy.
consumption of electricity with a greater safety factor since the power
loss will not result in the release of the part from the chuck.
electromagnetic chucks are more expensive than permanent magnets.
a higher sensitivity to air gaps between the component and the chuck.
to fine tune because of the magnetic field and clamping force.
The Bottom Line -
Magnetic chucks are one of the most useful components for
surface grinding machines, speeding up the operational process. The above
information will make you understand the difference between each type of chuck
by giving you an idea of what will work the best for you. Well, it might be
challenging to draw a conclusion on which type is the best amongst all!
