As electromagnetic chucks can
provide variable holding power this is the reason which greatly improves their
ability to support a wide range of machining applications.
For holding Ferro-metallic work
pieces with a strong, uniform holding force magnetic chuck from Magnet
Manufacturer are designed. They constitute accurately centered
permanent magnetic face that works in conjunction with an operator actuated
permanent or electromagnet. To create a secure anchor for the work piece the
work piece closes the magnetic loop.
Shop Safety
Over permanent magnetic chucks the
variable holding power of electromagnetic chucks give it an advantage. But
their selection generally depends both on the machining application and shop
safety. Since, to operate Motor arc Magnets
need constant power but a power failure can introduce a worker safety concern.
While to address these concerns
uninterruptible power supplies, power conditioners and battery backup systems
can be integrated into the machining operations but on the design of a
particular machining application the ultimate decision relies.
Electromagnetic Chuck Operation
The constructions of
electromagnetic chucks are with electrical coils wound around a steel core
embedded in the chuck. A chuck controller from Magnet
Factory in China is used to generate a variable DC voltage in the
chuck's coils to energize the electromagnetic field. Electromagnetic field of
the coil causes particles within the Ferro-metallic work pieces to be aligned
in a common direction.
Between the work piece and the
chuck this alignment creates the electromagnetic holding force. As long as
voltage is applied the chuck's poles are magnetic. To vary the strength of the
magnetic field the operator can adjust the controller's DC voltage, which, in
turn, provides the variable holding force.
The Variable Holding Power Advantage
The chuck's ability is improved
by the variable holding power to support a wide range of machining applications
that include shaping, cutting, milling, EDM, high speed cutting operations and
thin work for grinding. For automation purposes electromagnetic chucks can
easily be interfaced with machine centers.
