Novel single crystal diamonds for waterjet cutting applications

摘要

By tests in the laboratory and in a normal industrial environment it could be shown that monocrystalline synthetic diamond orifices in well designed waterjet cutting heads are extremely resistant to abrasives as well as to foreign particles and other impurities in water. As a result, very good and constant waterjet quality as well as constant volume flow, necessary to insure consistent cutting quality, can be maintained for very long operating times without orifice change in the cutting head. Furthermore water produced employing a reduced water treatment is sufficient for WJ-cutting operations. All this considerably reduces cutting costs compared to using cutting heads with sapphire, natural diamond or polycrystalline diamond equipped orifices. It can be stated that the orifice problem could be solved with novel MCSD-waterjet orifices.
