Airbrasive Jet Machining
Also called MicroBlast Machining is aprocess 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 abrasivestream used for cleaning, cutting, drilling,deburring.

Airbrasive Jet Machining
Airbrasive Machines areextremely versatile and have
limitless applications. Theyhave the power to cut anddrill materials as hard asdiamonds as well as theprecision of delicate items
like fabric and paper.

Fluid Jet Machining
Water-jet machining
It is manufacturingthrough the use of highly
pressurized liquid, forcedthrough a nozzle andused as the cutting tool.
The orifice can range
from 5 to 20 thousandthof an inch.

Fluid Jet Machining
Water-jet machining
Water is most common liquid, howeveralcohol,oil, or glycerol may be used
Water jets machining has been in use since1970.
Water jets have many applications ranging from cutting steels to sheets of candy
(using a sugar water or syrup for cutting).

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

Fluid Jet Machining
Advantages of water-jet machining
The water streammakes very littlenoise.
Chips or waste is
moved out of the wayof the cutting process.

Fluid Jet Machining
Advantages of water-jet machining
Especially suited forshort run productionbecause there are notooling expenses.
There are no heataffected zone's.

Abrasive Jet Machining
Abrasives, such asgarnet, diamond or
powders, can bemixed into the waterto make a slurry withbetter cutting
properties thanstraight water.

Advantages of Abrasive Jets
Quality finish
Materials cut by the abrasive jet have asmooth, satin-like finish, similar to a fine
sandblasted finish.
Minimal burrNo heavy burrs are produced by the
abrasive jet process. Parts can often be
used directly without deburring

Advantages of Abrasive Jets
over Water Jets
Increased Accuracy
Compared to the
water jet 0.010,abrasive jets average
from 0.00 5.
In this example, thewall are a 0.025
wafer thin.

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