Zusammenfassung:	The invention belongs to the technical field of microelectronic tools, and particularly relates to a wedge-shaped chopper material and a preparation method thereof. The wedge-shaped chopper material is of an integrated structure and comprises a cylindrical rod body (1) and a transition type wire penetrating hole (2) formed in the cylindrical rod body (1) along the central axis, and a thick wire penetrating hole (3), a transition hole (4) and a thin wire penetrating hole (5) are formed in the middle of the transition type wire penetrating hole (2). Meanwhile, a preparation method is provided, hard alloy or ceramic powder and a binder are mixed to prepare slurry, needed powder is prepared through a spray drying process, printing forming is conducted through a binder spray forming process, and high-performance forming of the wedge-shaped chopper bar is achieved through sintering and subsequent densification treatment. The invention provides the high-precision, high-efficiency and high-cleanliness preparation met
