HOW DO WE POLISH PROPELLERS UNDERWATER?
A super smooth surface is inhospitable to marine organisms as well as being beneficial to the efficiency of the propeller. UMC have constantly improved the standard of their surface finish. A recent enhancement to meet stringent military requirements involved a major redesign to provide a higher power rating combined with exceptionally fine abrasives.
Our equipment provides a suction force of 100kg to the propeller surface but can be manoeuvred over the blade face easily by the diver. We can use abrasive sizes down to 360-grade grit to produce a surface finish of 0.5ยต Ra.
