Magnetic Chuck can provide variable holding power, which greatly improves their ability to support a wide range of machining applications. Magnetic chucks are designed for holding ferro-metallic work pieces with a strong, uniform holding force. They consist of 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 create a secure anchor for the work piece. Electromagnet vs. Permanent Magnet Both permanent magnets and electromagnets can be used to produce a magnetic holding force. The choice of a permanent or electromagnetic design is dependent upon both machining applications and externalities. Since permanent magnets do not require electrical power, they are best used when there's no power available or it is unreliable. On the other hand, the magnetic field of permanent magnetic chucks cannot be adjusted, which can be a drawback for machining applications that require variable holding power. In applications where a variable holding power is required, an electromagnetic chuck is the better solution. Operation of Electromagnetic Chuck Electromagnetic chucks are constructed with electrical coils wound around a steel core embedded in the chuck. To energize the electromagnetic field, a chuck controller is used to generate a variable DC voltage in the chuck's coils. The coil's electromagnetic field causes particles within the ferro-metallic work pieces to be aligned in a common direction. This alignment creates the electromagnetic holding force between the work piece and the chuck. The chuck's poles are magnetic as long as voltage is applied. The Advantage of Variable Holding Power Variable holding power greatly improves the chuck's ability to support a wide 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 centers for automation purposes. Variable holding power is critical for thin work applications. For example, when a part to be machined is thin-0.25 inch or thinner-and the part is presented to a machine operator as one of a stack of similar parts, the piece must be lifted from the stack. Industrial Magnet is not designed to lift only one piece from a stack of ferro-metallic parts.

As far as the strength is concerned, neodymium magnets offer the highest strength. Therefore, even small units are quite effective. Since they are quite useful, you can find a versatile collection of them. Chances are that you have one in your own pocket as well. In this article, we are going to talk about the uses of neodymium magnets. Read on to find out more. Door Catches You can find neodymium magnets in residential, commercial and public buildings. Typically, they are used in many door catches. Basically, the pot or countersunk types are used for attracting steel disk. Alternatively, a magnet mounted on the wall. These strong products are powerful enough to hold the door weight. Dentures These magnets are used in different types of corrective devices. For instance, dentures use them to hold together the replacement dentures, especially where some teeth are not there. Bearings Actually, magnetic bearings utilize levitation in order to provide support for the moving parts. And the good thing is that there is no physical contact. The goal is to allow relative motion without a lot of friction and mechanical wear and tear. Generators and Motors Usually, electric motors use a combo of permanent magnets and electromagnets. These units are used to create mechanical energy from electrical energy. On the other hand, a generator uses mechanical energy and converts it into electricity. Magnetic Therapy While there is not enough clinical evidence of their efficacy, neodymium magnets are used to relieve pain. Since they are strong, they are quite popular among those who believe in the efficacy of magnetic therapy. MRI Scanners These machines generate a powerful field that helps with the alignment of the protons in the subject's body. Then radio waves are fired at the body in order to create detailed images. Typically, big MRI machines found in hospitals contain big neodymium magnets and Magnetic Filter Rod. With these tiny products, doctors save thousands of lives every day. Long story short, these are some common uses and applications of these products. If you want to enjoy these benefits, we suggest that you go ahead and buy high quality units from a reputable seller. |
