The invention relates to a method for processing a flexible metal-plastic thrust bearing bush of a main transmission box for milling equipment with laser, belonging to the metallurgical field. The graphite is used as coating, and the impact wave induced by strong laser is used to impact the surface of the flexible metal-plastic thrust bearing bush with laser so as to improve the density of a plastic layer on the surface, form a small pit of a certain depth on the surface of the plastic layer and increase the adhesion and the oil storage performance of a lubricating oil film on the surface. When the supply of the high-pressure lubricating oil interrupts, the lubricating oil stored in the small pit on the surface of the plastic layer can maintain the existence of the lubricating oil film, and the graphite particles embedded in the plastic layer can fulfill the lubricating function after the lubricating oil film disappears and before the surface of the flexible metal-plastic thrust bearing bush is impacted with
