Flow International Corp. (Kent, Wash.) has developed a new version of its WMC2 waterjet machining center with 87,000 psi waterjet cutting. Benefits of the system, when compared to 60,000-psi systems, include cutting speeds that are reportedly 30 percent to 50 percent faster, resulting in 20 percent to 30 percent lower part costs and 30 percent to 50 percent less abrasives use. The company reports that the higher pressure increases the waterjet water stream’s power and density by as much as 40 percent, which means that each abrasive particle moves faster and with more energy. The system can cut composites, plastics, metal, glass, ceramics, metal or stone in thicknesses up to 8 inches/406 mm.
