Magnetic tools are essential for various machining processes. Any movement can affect the precision and resulting quality of a work piece. These tools ensure that work pieces stay in place during a process. Magnetic table allow for convenient securing and unlocking of work pieces. A simple turn of a knob or flip of a switch can activate or deactivate the magnet. The use of a magnetic tool is very straightforward.
There two main types of magnetic tools, the permanent and the electromagnetic tools. Both types have advantage and disadvantages. An electromagnet requires electricity for it to generate magnetic power. A permanent magnet does not require electricity which helps in lowering the cost of operation. The problem with a permanent magnet is that chips and fragments from iron and other metals can stick to the magnet and become very hard to remove because its magnetic force cannot be turned off.
In order to further understand the main difference between the two, it is important to learn about the basics of magnetism. During the ancient times, man discovered a special type of rock called a lodestone that pulled other types of rocks and materials such as iron towards it. The pulling force is called magnetism. The objects that exert this type of force are called magnets.
Permanent magnets are materials that maintain their magnetism regardless of the surroundings. A magnetic force constantly exist between permanent magnets.
Temporary or soft magnets are materials that are attracted to magnets but are not permanent magnets themselves. An example is iron. Non-magnetic materials are materials that does not react to magnet. Examples include wood, paper and plastic.
