4. Magnetization Direction Of Arc Magnet

5. Machining Process of Neodymium Countersunk Magnet
Besides large-sized product with regular shapes, sintered Neodymium magnet is hard to achieve the required shape and dimensions directly owing to the technical restrictions in the magnetic field orientation molding process, therefore, machining process of sintered Neodymium magnet blank is always inevitable, especially Neodymium countersunk magnet. As a type of hard and brittle cermet material, sintered Neodymium magnet is criticized by its machinability, hence there are only cutting, grinding, and drilling can be applied to its machining process in traditional machining technology. Hole Machining process includes both through hole and countersunk hole. Countersunk hole should be processed on the basis of through hole. In order to ensure concentricity between through hole and the countersunk hole, workpiece is required to be fixed accurately during the machining process of the countersunk hole.
