As with any industrial equipment, there are certain components of waterjet cutting systems that are expended during operation. These consumables will need regular replacement to keep the machine running efficiently. In an abrasive waterjet, garnet will account for the bulk of consumable expenditure. However, both abrasive and water-only machines contain parts in the pump and cutting head that are constantly exposed to extreme conditions, causing them to eventually wear out. One such part is the waterjet orifice, a small metal disk containing a gem that focuses the waterjet stream.
