L & R was awarded the contract to build this OWTS ( Oily Water Treatment System ) on behalf of KH Technologies for evaluation by NAVSEA. It is a fully automatic system capable of discharging water at 50 gpm with oil content of less than 15 ppm. We are very proud of this unit and look forward to manufacturing subsequent systems for military and commercial applications.
We have built a wide variety of assemblies, test fixtures and tooling for the nuclear industry over the years.
We have made several variations of titanium base plates in multiple quantities. These were for antenna systems that were installed on British and U. S. submarines. This particular version starts out as a 255 pound blank and finishes out at 63 pounds and has 117 tapped holes in it.
This component was part of a DOE project and our customer has requested that we disclose only limited information about this. What is of significance from a machining perspective is there are 131,589 holes in this part. They are tightly toleranced for location and size and practically speaking none are perpendicular to the surface. We made many configurations of these and they were run on one of our vertical mills utilizing a trunnion table.

These are power amplifier blocks that are used on the Warm Cartridge Assembly on NRAO’s ALMA Antenna Array in Chile. Surface finishes on the side walls of the channels are very critical.
