Variable holding power can be offered by Electromagnetic chucks. To support a huge range of machining applications, it greatly improves their ability.

For holding Ferro-metallic workpieces with a uniform, strong holding force, Magnetic Chuck China is designed. Working in conjunction with an electromagnet or operator actuated permanent; they consist of an accurately centered permanent magnetic face. The workpiece to produce a secure anchor for the workpiece closes the magnetic loop.

Electromagnet vs. Permanent Magnet

To produce a magnetic holding force, both electromagnets and permanent magnets can be used. Upon both externalities and machining applications, the choice of an electromagnetic or permanent design is dependent. When it is unreliable or there's no power available, they are best used since permanent magnets do not require electrical power.

The magnetic field of permanent magnetic chucks on the other hand cannot be adjusted, which for machining applications requiring variable holding power can be a drawback. An electromagnetic ...

Electromagnetic Chuck Operation

With electrical coils wound around a steel core embedded in the chuck, Electromagnetic chucks are constructed. To generate a variable DC voltage in the chuck's coils, A chuck controller is used to energize the electromagnetic field. Within the Ferro-metallic workpieces to be aligned in a common direction, the coil's electromagnetic field causes particles.

Between the chuck and the workpiece, this alignment creates the electromagnetic holding force. The chuck's poles, till voltage is applied are magnetic. To change the strength of the magnetic field, the controller's DC voltage can be adjusted by the operator. This offers the variable holding force.

The Variable Holding Power Benefit

The chuck's ability to support a wide range of machining applications that include milling, cutting, EDM, shaping, thin work for grinding, and high-speed cutting operations is enhanced by Variable holding power greatly. With machine centers for automation purposes, Electromagnetic chucks can easily be interfaced.

For thin work applications, Variable holding power is critical. For example, the piece must be lifted from the stack when a part to be machined is a thin-0.25 inch or thinner-and the part is presented to a machine operator.

From a stack of Ferro-metallic parts, Permanent magnets are not designed to lift only one piece. However, to decrease the magnetic strength to the point where only one piece at a time can be lifted from a stack of parts, an electromagnet with variable voltage control allows the operator.

Shop Safety

An advantage over permanent magnetic chucks is given by the variable holding power of electromagnetic chucks. But their selection depends both on shop safety and the machining application. Into the machining operations to address these concerns, power conditioners and battery backup systems can be integrated while on the design of a particular machining application, uninterruptible power supplies the ultimate decision depends.
