Innovation creates possibilities

Yaw ring repair

CNC Onsite has developed a unique patented concept to make Up Tower repair on Yaw Ring.

We have developed a CNC controlled milling machine that removes the damaged teeth. In the milled pocket a new tooth segment is mounted, and the turbine can quickly be back in operation.
