Commonly, “Water jet”can be used as both “water-only” water jet and “abrasive” water jet cutting. Water-only water jets cut with ultra-high pressure water alone. Abrasive water jets cut with an abrasive material (usually garnet) which added to the water stream. Water-only water jets are used to cut through softer materials such as rubber and foam. Abrasive water jets are used to cut through harder materials such as plastic, composites, stone and metals.
