The invention discloses a sprayer processing technique capable of lowering processing difficulty, which comprises the following steps: A) blank forging; B) heat treatment; C) machining; D) surface hardening; and E) machine finishing. The step C) is performed before the step B). In the step A), the material of the blank is 45# steel, the forging temperature is 875-1025 DEG C, and the forging heat source adopts a reverberatory furnace; the step B) comprises quenching and tempering after the quenching; the step D) surface hardening is arranged after the step C) and is plasma surface hardening treatment; and the step E) is arranged after the step D). The technique is simple, and can be used for obtaining the sprayer satisfying the strength requirement by adopting the cheap and accessible materials and the reasonable technique. Compared with the prior art, the technique has lower processing difficulty, and is beneficial to enhancing the production efficiency of the sprayer, lowering the production cost of the sprayer and improving the sprayer quality.
