Flap Peening Equipment that meets AMS 2590 and Nadcap Audit Requirements

Flap peening with motors that meet AMS 2590 and Nadcap audit requirements

The requirements for flap peening have become more stringent since the new specification AMS 2590 was put in place. The rotary tool should be capable of operating at the specified operating speed within +/-100 RPM while the flap assembly is in contact with the work piece. Furthermore, Nadcap Audit requirements concerning rotation speed and sustained RPM have to be met.

In order to address those demands, Peening Accessories uses a high-end Suhner ROTOMAX motor with flexible shaft to meet this requirement. The company has been looking for such a motor for quite some time, since demands, especially in the aviation industry, are becoming very stringent. Some of the customers using flap peening equipment demand a motor that comes with an rpm accuracy of +/-2 % within the specified rpm range. On top of that, the motor must include an RPM display. That is a requirement that many motor manufacturers can not at present fulfill.

There is no need for a direct peening intensity setting since it can only be an rpm control based on an estimated intensity/rpm correlation. Such a correlation is to be found in AMS 2590. In all cases the intensity must be verified with Almen strips.

The design employed in the new Rotomax takes full account of the exacting demands made on contemporary industrial machinery. It satisfies each and every requirement the market expresses today in terms of performance, ease of use and safety.

The Suhner ROTOMAX 1.5 - Flexible Shaft Machine, which comes with a stand, has the most powerful drive for various tasks. A keypad on top of the housing makes selecting the desired speed – shown in a display – both quick and easy. Electronic speed regulation is implemented here. The new motor system delivers up to 1,500 Watts and rotates at between 500 and 15,000 rpm and is of course, continuously adjustable. Everything is adjusted and controlled digitally. A soft start, stable speeds, and an active braking system are the decisive advantages of the unit's electronic controls. Low speeds down to 500 rpm are also possible with this system. Power is not the same as mass: the high-performance motor in the metal housing is robust, but thanks to its light and compact design, it is also suitable for portable use. The motor has a power output of 1,500 Watts, a power consumption of 2,200 Watts and a shaft connection of DIN 10. The supply voltage is 230 V, 50/60 Hz, 1 phase and its weight is 27 kg.
