Toyo Seiko Web Site:Ultrasonic Shotpeening Equipment

Saving space
Partial injection to larger parts
1)No need for cabinet
2)No need for dust collector
Clean operation lines
Improvement in operation ecvironment(dust and noise) because of no dust collector used in lines
Shotpeening effect
*Compressive residual stress induced is approximately
　the same or more compared to conventional shotpeening
*Surface finishing is better than conventional shotpeening
=effective for surface durability
*Injecting time is longer than conventional shotpeening
=part by part maintenance can be done by impact sensor

Portable type
Most suitable for partial treatment of larger parts
Pin type
Shotless peening can be conducted (No media needed)
Because of more weight,pin type can peenform with
larger energy compared to conventional shotpeening
(Also suitable for reforming after peenforming)

Equivalent compressive residual stress
as conventional shotpeening can be achieved
