water raise & lowerFor many abrasive waterjet applications, underwater submerged cutting is the best solution. For materials like steel, stainless, aluminium, copper, bronze, Inconel, titanium, and other metals, as well as materials like glass, stone, marble, granite, etc., submerged cutting offers two big advantages:

Reduced noise

  • a typical abrasive waterjet stream travels over three times the speed of sound and as it travels through the air, the turbulent passing air generates noise levels over 100 dB, even as high as 120 dB.
  • by raising the water level and submerging the material, “the operating noise level” is reduced below safety limits.

Less mess

  • the typical high pressure waterjet piercing process results in an abrasive jet stream that “rooster tails” back into the environment for the duration of the pierce, anywhere from just a few seconds on the thin materials, up to several minutes, depending on the thickness and hardness of the material.
  • If the material is not submerged, that diffused stream shoots back into the environment, and literally gets everywhere including on the beams, rails, bearings, controller, electronics and anywhere else.
