Magnetic chucks are designed for holding ferro-metallic work pieces with a robust, uniform holding force. They contain an accurately centered permanent magnetic face that works in conjunction with an operator actuated permanent or electromagnet. The work piece closes the magnetic loop to make a secure anchor for the work piece.

Operation of Electromagnetic Chuck

Magnetic Chuck China is constructed with electrical coils wound around a steel core embedded within the chuck. To energise the electromagnetic field, a chuck controller is employed to get a variable DC voltage within the chuck's coils. The coil's electromagnetic field causes particles within the ferro-metallic work pieces to be aligned during a common direction. This alignment creates the electromagnetic holding force between the work piece and therefore the chuck. The chuck's poles are magnetic as long as voltage is applied. The operator can adjust the controller's DC voltage to vary the strength of the magnetic flux, which, in turn, ...
... provides the variable holding force.

Permanent Magnet and Electromagnet

Both permanent magnets and electromagnets are often wont to produce a magnetic holding force. The selection of a permanent or electromagnetic design depends upon both machining applications and externalities. Since permanent magnets don't require electric power, they're best used when there is no power available or it's unreliable. On the opposite hand, the magnetic flux of permanent magnetic chucks can't be adjusted, which may be a drawback for machining applications that need variable holding power. In applications where a variable holding power is required, an electromagnetic chuck is that the better solution.

Shop Safety

The variable holding power of electromagnetic chucks provides it a plus over permanent magnetic chucks. But their selection depends both on the machining application and shop safety. Since electromagnets need constant power to work, an influence failure can introduce a worker safety concern. While uninterruptible power supplies, power conditioners and battery backup systems are often integrated into the machining operations to deal with these concerns, the last word decision depends on the planning of a specific machining application.

Benefit of Variable Holding Power

Variable holding power greatly improves the Industrial Magnet China ability to support a good range of machining applications that include cutting, milling, shaping, EDM, high speed cutting operations and thin work for grinding. Electromagnetic chucks can easily be interfaced with machine centres for automation purposes.

Variable holding power is critical for skinny work applications. for instance , when a neighborhood to be machined is thin-0.25 inch or thinner-and the part is presented to a machine operator together of a stack of comparable parts, the piece must be lifted from the stack. Permanent magnets aren't designed to lift just one piece from a stack of ferro-metallic parts. However, an electromagnet with variable voltage control allows the operator to decrease the magnetic strength to the purpose where just one piece at a time are often lifted from a stack of parts.
