Machining counter bored holes in syntactic foam blocks

These syntactic foam blocks needed modification to fit to an ROV.
Syntactic foam blocks are used as ballast on ROVs to allow them to work properly underwater and syntactic foam is used as it enables them to work at great depths without issue from the pressure of the water at depth.
ROV’s are Remotely Operated Vehicles, ROV for short.
and when certain projects are worked on the ROV is adapted to adjust the buoyancy for the load it is carrying/working with.

We programmed and machined the counter bored holes on a cnc milling machine

The syntactic foam blocks were a little over 2mtrs long, which made them a little more difficult to machine and great care was required so as not to damaged the syntactic foam blocks in the process.

Syntactic foam is made up of lots of small perfectly formed glass spheres.
The syntactic foam block is brightly colored so it can be seen easily underwater.
