X-Y Milling of Radar Dome Pedestal Foundations

Fast Response And A Precise Job For Norwegian Naval Destroyer

A Norwegian shipyard contacted Goltens to take over a pressing job that another company had committed to but could not complete. The job was to machine four pedestal foundations for radar domes on a naval destroyer.

The foundations, as constructed, were too rough and uneven to mount the domes. Goltens quickly evaluated the technical requirements and immediately mobilized two in-situ machining technicians and its X-Y milling machinery to the shipyard to start the work.
