The invention discloses a CuSe compound rotating target preparation method. The CuSe compound rotating target preparation method comprises the steps that a non-magnetic pipe is selected as a substrate; CuSe powder is sprayed onto the outer surface of the pretreated substrate through an supersonic cold spraying technology, and the thickness of a deposited layer is not larger than 20 mm; the densityis further improved at ultrahigh pressure through an isostatic cool pressing technology; and a rotating target blank of the corresponding organization structure is obtained through high-temperature sintering, and a rotating target is obtained through machining. The CuSe compound rotating target obtained through the method is uniform in inner density, good plating film forming is facilitated, andthe defective percentage of solar energy products is decreased.
