This invention provides a method for processing a tapered roller bearing cage. Step one: The sheet metal is cut, stretched, punched with window holes, edge-machined on the large end face, and then the bottom is cut to form a cage blank. Step two: The window beam is beveled to create a guide slope that contacts the rolling elements. The guide slope of the cage meets a first surface roughness requirement, while the remaining non-working surfaces of the cage only need to meet a second surface roughness requirement, which is higher than the first. Step three: A protective component is placed over the window holes of the cage blank, with the coverage area of ​​the protective component being larger than the beveled surface after finishing. Step four: The covered cage blank undergoes two shot blasting treatments. If the surface quality of the cage does not meet the requirements, the surface treatment process parameters need to be adjusted for a third shot blasting treatment. This method solves the problems of low efficiency and high cost associated with the existing all-around finishing process for bearing cages.
