[Problem] To provide a process for producing a sintered magnet, said process reducing the machining allowance in working a sintered magnet and thus enhancing the materials yield. [Solution] This process includes: a forming step of press-forming a magnet powder, which is to constitute an R-Fe-B sintered magnet (wherein R is a rare earth element component comprising Nd as the main component), to form a green compact through the compression of the magnet powder; a sintering step of heating the green compact to a prescribed temperature to sinter the green compact and thus form a sintered magnet; and a dimension correction step of pressure-molding the sintered magnet with the sintered magnet heated to a temperature not exceeding the sintering temperature to correct the dimensions of the sintered magnet. |
