The invention discloses a deep groove ball bearing ferrule machining process. The process comprises the steps of (1), blanking; (2), end face chamfering; (3), hardening and tempering; (4), end face grinding; (5), punching; (6), inner diameter turning; (7), groove diameter turning; (8), machining of sealing slots in the front side and the reverse side; (9), surface grinding and the like. The size and weight of a deep groove ball bearing machined through the process are effectively reduced, and meanwhile the load is increased. The service life of the deep groove ball bearing is prolonged, the overall quality of the deep groove ball bearing is improved, machining can be performed on an automatic lathe, production efficiency is improved, and the production cost is low.
