Unlike the conventional shot peening which was often used to improve the fatigue strength of gears, the OX-FSP process provides the precise selections of shot condition to fit to material quality, heat treatment background, hardness of an object, and environment in use, that allows the process under an optimal condition, and as the result, the fatigue strength and sliding performance are considerably improved.
The shot peening is the technology to jet particles as small as several 10 micron meters with compressed air and let them hit on an object at a high speed.
The original shot peening flow speed was about less than 100m/sec or more in OX-FSP.
Consequently, a better heat treatment on surface, higher residual compressive stress, and excellent sliding performance are realized.
