The invention discloses a turning method for an angular contact ball bearing with an outer ring being provided with an elastic support and relates to the technical field of machining. The problems that existing angular contact ball bearings with outer rings being provided with elastic supports are complex in structure, the wall thickness of the parts provided with the elastic supports are small, the machining stability is poor, deformation is liable to occur, the machining precision requirements are difficult to meet, and the product quality is influenced are solved. The method comprises the following steps that firstly, a ferrule is subjected to primary finish turning; secondly, the ferrule is subjected to carburizing treatment; thirdly, the ferrule is subjected to secondary finish turning; fourthly, a bush is adopted for drilling of a flange plate hole and a threaded hole; fifthly, the ferrule is subjected to heat treatment; sixthly, the ferrule is subjected to hard turning; seventhly, a radial rectangular wedge hole of the ferrule is milled; and eighthly, the ferrule is ground, and machining of the angular contact ball bearing with the outer ring being provided with the elasticsupport is completed. The method is used for machining the angular contact ball bearing with the outer ring being provided with the elastic support.
