APW waterjet cutter
Underwater waterjet cutting reduces the noise to under 75dB and eliminates material frosting within 1/16″ from the jet. The downside of this process is you need water level control on your catcher in order to see the underwater cutting process. Without the control, you need to work underwater and handle the waterjet cutting process.
