The heavily damaged surface of the journal is salvageable!
- If the scratches are too deep and it is possible to make mating elements (e.g. bearing shells) on a slightly smaller shaft diameter, then turning is enough to remove scratches and grooves and obtain the right surface quality.
- If it is important to maintain the original diameter, the turning operation must be preceded by premachining (optional) and layer welding. Only then can the original geometry be restored. We implemented such technology, for example, in the Bujagali power plant, Bujagali HPS, Uganda | WWTECH – On site machining
- In both cases, the last step of treatment can be honing using the same machine tool.
