Advantages of Cavitation S Peening® |
![](../../image/icon.gif) | Peened surface is extremely smooth (see Fig.3). |
![](../../image/icon.gif) | Shots are not necessary, i.e. Shotless peening. |
![](../../image/icon.gif) | It is easy to peen bottom of gear teeth and/or narrow region (see Fig.4). |
![](../../image/icon.gif) | There is no thermal effect to material surface. |
![](../../image/icon.gif) | Expensive plunger pumps are not required, since the impact force of cavitation bubble was used. |
![](../../image/icon.gif) | It is easy to control the peening area. pressure, nozzle size and injection time are same.) |
