4) heat treatment, is quenched tempering by continuous oven, and after temper, Hardness Control is at HRC60-HRC64；
5) with the external diameter of centreless grinding mill locating snap ring；
6) positive and negative two planes of hard grind locating snap ring；
7) on inner circle mould, grind the internal diameter of locating snap ring；
8) locating snap ring tow sides internal diameter, outer diameter chamfering；
9) by locating snap ring under the temperature conditions of 125-135 DEG C, keep 6-10 hour, then natural cooling in air, half-and-half
Finished product carries out stabilized treatment, eliminates machining stress；
10) positive and negative two planar accurate grindings of locating snap ring.
Described a kind of locating snap ring processing method, it is characterised in that described locating snap ring selects GCr15 bearing steel.
