The invention discloses a NdFeB permanent magnetic material processing method which includes the step of material binding and the step of cutting. In the step of material binding, a material plate is attached to a smooth and flat cushion plate in an adhesive mode through an adhesive, bar-shaped materials to be processed are attached together through the adhesive, the attached bar-shaped materials to be processed are positioned and attached to the material plate for processing, and the adhesive can not permeate the cushion plate; in the step of cutting, a cutting zero point is determined, cutting parameters are set, arc cutting, wire retracting and unloading are sequentially finished after cutting through a multi-wire sawing machine, and the cutting parameters are set in the mode that unwinding tension is 10-40 N, winding tension is 10-40 N, cutting speed is 10-500 mm / s, reciprocating time is 10-60 S, arc suppression time is 500-2000 S, and new wire feeding speed is 20-40 m / min.
