The successful repair of a Turbine Disk

Job name: Turbine Disk
Type of work: Machine boring

Duration: 2 days
Machinery: Robbie 3615 CNC Universal Grinder

The component was a high precision compressor rotor disk that required repairing.

Our team machine bored it true and square to original datum points within 0.005mm. This was a challenging job as it was difficult to hold it in

place as it could not be gripped on the outside diameter.

We overcame this by pulling the disk back to a known flat datum and clamping with minimal force, so as not to distort the original datums.
