2) make annealing treatment：Blank in step 1) is made annealing treatment, annealing temperature is 800-900 DEG C, keeps the temperature 4-7h, Cooling；
3) frustrate and cut：Processing is cut using frustrating the machine of cutting the blank in step 2) frustrate, the burr for ball blank surface of going out；
4) roughly grind：Corase grinding processing is carried out to the blank that step 3) obtains using numerically control grinder, is started the cleaning processing after grinding；
5) quenching treatment：The blank that step 4) is obtained is put into glowing furnace and quenches, and temperature is 700-850 DEG C, heat preservation After 3-5h, cooling；
6) fine grinding：Fine grinding is carried out until reaching requirement on machining accuracy to the blank that step 5) obtains.
Preferably, forging and stamping temperature is 1100 DEG C in step 1).
Preferably, in step 2), annealing temperature is 850 DEG C, soaking time 6.5h.
Preferably, the temperature of quenching is 770 DEG C in step 5), soaking time 4h.
The raw material of present invention processing ball are GCr15SiMn steel by hot forging pressure, first annealing, rear thick machining, is quenched again The program refined after fire, improves the uniformity of ball interior tissue, so improve the hardness, wearability, toughness of ball with And service life, the comprehensive mechanical property of ball is improved, and then ensure that the performance and service life of bearing.
