The difference is that the hammer has become a small projectile with a diameter of no more than one centimeter, and the iron metal has become a more excellent alloy raw material. ???? ??????? ??? ??? ????? ???? ?? ?? ??? ??? ??? ??? ?? ????? ????? ?? ??? ??? ?????? ??? ??.

Such thick alloy raw materials, under the high-frequency and high-speed impact of hundreds or thousands of projectiles, become hard, complex in shape, and very thin skin. Finally, they are combined with the skeleton to form a complete wing, supporting the aircraft to fly at an altitude of tens of thousands of meters. ?? ???? ???? ???

The fatigue life of parts processed by shot peening can be increased by dozens of times compared to the original, and the fatigue strength and corrosion resistance are greatly enhanced.

?? ?????? ?? ????? ??? ???? ??. In a specialized processing equipment, bullets are ejected from the shot material box through a spray gun, hitting the surface of the parts at high speed. Then, through a recycling system, unqualified bullets are screened out by a screening device and returned to the shot material box for reuse.
