• Touch Screen User Interface

FASTER:

• With the personalized Intensity versus RPM curves for up to 5 operators
• Spend less time on preparation and more time peening.

EASIER:

• Press start and get the exact rotational speed

• Use the integrated stopwatch or countdown timer to do saturation curves.

• Easily meet Nadcap and other process requirements
