Introduction To The Wood Lathe Chuck

Electromagnetic chucks can offer variable holding power, which significantly enhances their ability to support a broad array of machining applications.

Magnetic chucks are made for holding Ferro-metallic workpieces with a solid, uniform holding force. They consist of a correctly centered permanent magnetic face which operates together with an operator actuated permanent or electromagnet. The workpiece closes the magnetic loop to make a secure anchor to the workpiece.

Permanent Magnet vs. Electromagnet

Both permanent magnets and electromagnets can be used to make a magnetic holding force. The option of a permanent or electromagnetic design depends upon both machining programs and externalities. Since permanent magnets do not require electrical power, they’re best used when there’s no electricity available or it’s unreliable.You can also browse http://www.plusmax.co.th/!/KITAGAWA/56ab8e738054dfdc55a003f5 for buying kitagawa chuck.

On the other hand, the magnetic field of permanent magnetic chucks can’t be adjusted, which is a drawback for machining applications that require variable holding power. In applications where a factor holding power is needed, an electromagnetic throw is the better alternative.

Electromagnetic Chuck Operation

Electromagnetic chucks are built with electric coils wrapped around a steel core embedded in the throw. To energize the electromagnetic field, a thrown controller is used to create a variable DC voltage from the chuck’s coils.

The coil’s electromagnetic field causes particles inside the Ferro-metallic workpieces to be aligned in a common direction. This alignment creates the electromagnetic holding force between the workpiece and the throw.

The chuck’s poles are magnetic so long as the voltage is applied. The operator can adjust the control’s DC voltage to change the strength of the magnetic field, which, in turn, supplies the factor holding force.
