  • Abrasive head with clean gas infeed
    Publication number: 20190366509
    Abstract: An abrasive head with clean gas infeed for cleaning/removing material surfaces and splitting/cutting materials by a liquid beam enriched with solid abrasive particles to extend the tool lifetime by eliminating damage to the liquid jet's aperture by the abrasive, avoid degrading the abrasive inside the tool and increase the cutting power and flow efficiency.
