When Optical Metrology Services designed its latest weld inspection tool, the Auga, they turned to HepcoMotion to supply the linear motion system required for this ground-breaking new internal weld inspection tool.
A camera and laser is mounted inside the Auga which is used to complete a full 360degree scan of the weld in under 20 seconds, recording a 3D topographic map to check the weld is within the product specification. The camera and laser require a slide and carriage to move them into the position required to check the weld; the GV3 provides this. As the camera and laser are moved backwards and forwards to inspect the pipe internally, it is critical to have a smooth movement. With its precision ground running surface, the GV3 provides a low friction and highly accurate system ideally suited to providing smooth indexing of the camera.
Auga utilises a GV3 spacer slide with rack, used with Hepco’s dowel pins, which ensures simple and quick mounting inside the Auga unit. GV3 provides a low maintenance, fit and forget solution – factors of key importance considering that time saving is a key advantage of the Auga. Usually, linear guides need to be frequently re-lubricated, requiring the machine to be stopped and causing costly and inconvenient downtime. With cap seals fitted, a key advantage of the GV3 is that it does not need to be re-lubricated, so it provides a long trouble free life. Featuring Hepco’s well-renowned V guide technology, the GV3 is the perfect choice in tough environments such as offshore engineering. The self-cleaning action eliminates contamination of the slideway – a key benefit for OMS working in the inevitably dirty welding environment.
The flexibility of the GV3 system is important for OMS – they are able to mix and match slides and bearings of different sizes to suit the application space and load requirements. GV3 offers a wide range of slide widths allowing the most rigid unit within the space available.
