Background

The neodymium magnet is also called a neodymium-iron-boron magnet, and is a tetragonal crystal formed of neodymium, iron, and boron. In 1982, the neodymium magnet was discovered by a person living in the special metal of Sumitomo. The magnetic energy product of the magnet is larger than that of a samarium cobalt magnet, and the magnet is the substance with the largest magnetic energy product all over the world at that time. Later, Sumitomo successfully developed powder metallurgy and general automotive successfully developed rotary spray smelting to produce NdFeB magnets. This magnet is a permanent magnet that is second only to absolute zero holmium magnets in magnetism today and is also the most commonly used rare earth magnet. Neodymium iron boron magnets are widely used in electronic products such as hard disks, mobile phones, earphones, and battery powered tools.

The wire cutting machine mainly comprises three parts, namely a machine tool, a numerical control system and a high-frequency power supply. The numerical control system consists of a single chip microcomputer, a keyboard and a variable frequency detection system and has the main functions of clearance compensation, linear interpolation, circular interpolation, automatic broken wire processing and the like. It can cut materials such as high strength, high toughness, high hardness, high brittleness, magnetic materials, and precision fine and complex shaped parts. Wire cutting techniques and wire cutting machines are being widely used in various industries. The machine tool comprises a machine body, a wire storage mechanism, a wire frame, an XY workbench, an oil tank and other parts. The molybdenum wire wound on the wire storage cylinder reciprocates at high speed through the wire frame. The processing workpiece is fixed on the XY working table. X, Y are controlled by a stepper motor. When the numerical control system sends a signal, the stepping motor moves one step, and the screw rods in two directions are driven to rotate through the intermediate transmission mechanism, so that the X, Y working tables are respectively fed.
