2. Airbrasive Jet Machining
Also called MicroBlast Machining is a process using:
High pressure air with fine powder, blended together to form an abrasive mixture.
This mixture is sent through a small, precisely machined nozzle.
The result is a highly accurate abrasive stream used for cleaning, cutting, drilling, deburring.

3. Airbrasive Jet Machining
Airbrasive Machines are extremely versatile and have limitless applications. They have the power to cut and drill materials as hard as diamonds as well as the precision of delicate items like fabric and paper.

4. Fluid Jet Machining Water-jet machining
It is manufacturing through the use of highly pressurized liquid, forced through a nozzle and used as the cutting tool.
The orifice can range from 5 to 20 thousandth of an inch.

5. Fluid Jet Machining Water-jet machining
Water is most common liquid, however alcohol,oil, or glycerol may be used
Water jets machining has been in use since 1970.
Water jets have many applications
ranging from cutting steels to sheets of candy (using a sugar water or syrup for cutting).

6. Fluid Jet Machining Some examples are:
Nickel alloys, Titanium, tool steels, glass, marble, brass, copper, wood, rubber, paper and plastics.
The cutting thickness is normally for any size under 6".

7. Fluid Jet Machining Advantages of water- jet machining
The water stream makes very little noise.
Chips or waste is moved out of the way of the cutting process.

8. Fluid Jet Machining Advantages of water-jet machining
There are no bits or tools touching the material surface, thus there is no tool replacement costs.
Ultrahigh-pressure Water-jets cut to accuracy's of +/-0.010".
Low level of mechanical stress (less than a pound) placed on the work piece preventing damage and deformations.

9. Fluid Jet Machining Advantages of water- jet machining
Omni-directional cutting capabilities allow the cutting of intricate shapes and curves not possible with conventional cutting tools.

10. Fluid Jet Machining Advantages of water- jet machining
Especially suited for short run production because there are no tooling expenses.
There are no heat affected zone's.

11. Abrasive Jet Machining
Abrasives, such as garnet, diamond or powders, can be mixed into the water to make a slurry with better cutting properties than straight water.

13. Advantages of Abrasive Jets
Quality finish Materials cut by the abrasive jet have a smooth, satin-like finish, similar to a fine sandblasted finish.
Minimal burr No heavy burrs are produced by the abrasive jet process. Parts can often be used directly without deburring

14. Advantages of Abrasive Jets over Water Jets
Increased Accuracy Compared to the water jet 0.010”, abrasive jets average from ”.
In this example, the wall are a wafer thin.

15. Versatile Machining
Cuts in wood

16. Versatile Machining
Etching- using a rapid feed rate.

17. Conclusion Jet Machining is the right choice of tools for:
Heat-sensitive or Brittle materials
Glass
Composites and Nonmetals
Burrless Applications
Produce long tapered walls in deep cuts
