[0002] NdFeB magnets, also known as neodymium magnets, are tetragonal crystals formed by neodymium, iron and boron. The magnetic energy product of this magnet is greater than that of samarium cobalt magnets, and it was the material with the largest magnetic energy product in the world at that time. This magnet is the permanent magnet with magnetic properties second only to absolute zero holmium magnets, and is also the most commonly used rare earth magnet. NdFeB magnets are widely used in electronic products. In the processing and production of neodymium magnets, it is usually necessary to cut the neodymium magnets.

[0003] The utility model with the existing authorization announcement number CN216528401U discloses a high-precision cutting device for NdFeB strong magnets, including a main body, a clamping mechanism, a sliding assembly mechanism and an orientation adjustment mechanism, wherein a clamping mechanism is arranged on one side of the middle part of the main body, and sliding assembly mechanisms are arranged on both sides and the middle part of the upper part of the main body, and an orientation adjustment mechanism is arranged on the inner side of the middle part of the sliding assembly mechanism, and the clamping mechanism includes an assembly groove, an electric propulsion short rod, a telescopic long rod and a clamping plate, and an electric propulsion short rod is arranged on one side of the inner part of the assembly groove, and a telescopic long rod is arranged in the middle part of the electric propulsion short rod, and the top of the telescopic long rod is provided with a clamping plate. The end is connected with a clamping plate, and the clamping plate forms a telescopic clamping structure through an electric propulsion short rod, a telescopic long rod and an assembly groove, and the electric propulsion short rod and the telescopic long rod are provided with two groups, and the sliding assembly mechanism includes a fixed side frame, a first middle slide groove, a left mounting cross bar, a connecting piece, a right mounting cross bar and a second middle slide groove, and the middle part of the side of the fixed side frame is provided with a first middle slide groove, the inner side of the middle part of the first middle slide groove is provided with a left mounting cross bar, and a connecting piece is fixed to the side of one end of the left mounting cross bar, and the other side of the connecting piece is connected to the right mounting cross bar, and the middle part of the inner side of the left mounting cross bar and the right mounting cross bar is provided with a second middle slide groove.
