Zusammenfassung:	The invention discloses a sputtering-free accurate paint spraying method and system. The paint spraying method comprises the following steps that S1, electrified treatment is carried out on paint powder and a workpiece, and the electrified type of paint is kept opposite to the electrified type of the workpiece; S2, paint powder is sprayed out to coat the workpiece; S3, during paint coating, the paint powder deposited on the surface of the paint is preheated and cured, and an ordered coating is formed on the surface of the workpiece; and S4, after the final coating is completed, main curing treatment is carried out, and the total curing heat is used for preheating the coating through heat conduction. According to the sputtering-free accurate paint spraying method, the deposited paint powder is preheated and cured, so that the coating composed of a plurality of single coatings is formed on the surface of the workpiece, the gas content in a film is reduced, the obtained coating is high in density and good in sur
