The permanent magnet chuck, also known as the magnetic chuck, is a magnetic fixture widely used in machinery factories, mold factories, and other machining fields, which can greatly improve the clamping efficiency of magnetic steel materials. The permanent magnet chuck uses high-performance rare earth material neodymium iron boron (N>40) as the core. By turning the handle of the chuck, the magnetic system of the neodymium iron boron inside the chuck is changed to hold or release the processed workpiece.
