The invention belongs to the technical field of spokes of engineering machinery, and aims to provide a production process of spokes for engineering machinery wheels. The production process specifically comprises twelve procedures of blanking, forming, punching, air hole punching, extruding and chamfering, air hole reaming, air valve hole punching, flattening, machining, drilling, counter sinking, steel seal stamping and the like. The unique extruding and chamfering procedures are adopted, the problem of micro cracks generated by air hole punching is effectively solved, and the machining efficiency and the installation performance of bolt holes are improved through the counter sinking technology. The prepared spokes of the engineering machinery wheels have the advantages of being high in strength, free of micro cracks, accurate in size, small in installation error, stable in physical and chemical performance, high in yield (larger than or equal to 99.5%) and the like, and can be widely applied to the field of engineering machinery wheels.
