Next level composite inspection performance

  • Market leading accuracy
  • Outstanding reliability
  • Highest productivity
  • High versatility
  • 40+ years experience
  • 50+ installations worldwide

Krautkrämer RokStar is a hybrid ultrasonic testing machine combining the dimensional control of cartesian gantry systems with the flexibility of articulating robot solutions. The result is a solid 13-axis scanning system with a broad field of application and universal scanning possibility. Using a wide selection of tool sets, it can accurately and efficiently inspect a large variety of manufactured parts: from large, relatively flat wing skins to small, complex 3D components on defect types like delaminations, inclusions, debondings, voids, porosity etc.

 

Inspection efficiency at all levels
The system that will not let you down

The robust test mechanics are considered the most accurate test mechanics in the market using low tolerance components made of stainless steel to ensure maximum precision, even for the inspection of large parts. The water filter system uses many different filter techniques for all relevant impurities. It thereby guarantees high-quality coupling water for every test application and facilitates the best results.

Boosting your operations

A multitude of modular UT electronics is available, ranging from high-precision single-channel applications to external high-performance transmitters as well as multi-channel phased array packages for critical application needs and highest test speed requirements.

Pulse Echo and Through Transmission Inspection capabilities are available individually but also in combination to maximize productivity.

Rock solid design

Krautkrämer RokStar’s unique design guarantees enhanced stability during scanner movement. The scanner rides on two steel beams in the primary X direction. All other axes are interpolating indexed axes. For scans of complex 3D parts, the machine uses an additional trigger axis to ensure equidistant data acquisition through the entire scan path. Individual testing mechanics designs and options like turntable, defect markers, customized tool sets etc. are availably to accommodate different part inspection requirements.
