To turn the magnetic holding force off and on,
Electro-permanent magnetic chucks only need
electrical power. This means thereby minimizing
heat build-up, the chuck runs power consumption
and cold parts distortion. Undesirable effects
such as rework due to thermal parts distortion
and an increase in rejected parts as well as an
increase in scrap are produced by heat buildup
during machining processes. To an increase in
material costs and cycle time, this all adds up
and in tool life, a decrease. To counter these
undesirable effects in two ways,
Electro-permanent magnetic chuck has the ability.

Basics of Magnetic Chucks Three basic types of
magnetic chucks are there electro-permanent,
electro-magnetic and permanent magnetic. On the
magnetism created by permanent magnets, the
permanent magnetic chuck is based and to operate,
they do not require electrical power making them
failsafe, but variable holding power capability
is not available with them. Around the chuck's
pole pieces, Electromagnetic chucks use a
controller to generate a D.C. voltage in a coil
wound to create the magnetic work holding force.
But to operate, continuous electrical power is
required in electro-magnetic chucks. Features of
both permanent magnetic and electro-magnetic
chucks in Magnetic Welding Holder are combined in
Electro-permanent magnetic chucks.

Hybridizing The Magnetic Circuit with
Electro-permanent A hybrid of the
electromagnetic and permanent chuck types are
Electro-permanent magnetic chucks. With a coil
wound around permanent magnetic material embedded
in the chuck plate, they are constructed. The
magnetic material is charged When a DC voltage is
applied, which even after power is removed binds
the work piece to the chuck and takes about 1
second. Controlling the amount of magnetic
force of the chuck is another function of the
coil and Magnetic Filter Rod to give it a
variable holding power capability similar to
electromagnetic chucks. Even when power is
removed, these chucks will remain magnetic. Since
without the consumption of electrical power, they
maintain their magnetic holding force the energy
efficiency of the process is increased by these
chucks, which minimizes costs to the entire
enterprise. They can be used with boring
machines, electric processing machine tools, as
well as in surface grinders, drilling, casting
and planning.
