Abrasive Jet Machining : 

Abrasive Jet Machining Fig : Schematic illustration of Abrasive Jet Machining

Water Jet Machining / Water jet cutting : 

Water Jet Machining / Water jet cutting

Water Jet and Abrasive Water Jet Cutting : 

Water Jet and Abrasive Water Jet Cutting Nozzle blast during cutting

Water Jets & Abrasive Water Jets : 

Water Jets & Abrasive Water Jets Water jets are used for soft material Abrasive water jets for hard material An abrasive element is added to the water beam to assist cutting Abrasive Water Jet Nozzle Diagram

Water Jets & Abrasive Water Jets : 

Water Jets & Abrasive Water Jets Water Jet Machinable Materials Soft rubber, foam, tin foil, carpet, soft gasket material Abrasive Water Jet Machinable Materials Titanium, aluminum, hard rubber, hardened tool steel

Abrasive Waterjet and Waterjet Part Examples : 

Abrasive Waterjet and Waterjet Part Examples Ceramic part cut with an abrasive water jet

Slide 7: 

Advantages of Water Jets Cuts all sorts of material with a single tool Minimum heat generation, material properties unaffected (unlike most other machining equipment) Makes it own start holes (unlike Electro Discharge Machinery) Smooth finish Cheaper than most machining options Programmable systems make accurate shapes with very good tolerances (+/- 0.02 inches) Disadvantages of Water Jets Tolerances deteriorate with material hardness and thickness Abrasive water jet nozzles are subject to heavy wear hence increasing the maintenance cost
