Ensuring Clean and Quiet Machining
There are a number of techniques that promote clean and quiet machining with the OMAX.
Keep the Abrasivejet Nozzle Under Water
Machining under water is significantly quieter than machining with the nozzle above water. There is also
less spray from the abrasivejet when under water. Keep the abrasivejet nozzle under ¼" to 2" (6 to 51
mm) of water during machining.
Note:
Raising the abrasivejet nozzle above the water once machining in finished, prevents the water and
abrasive mix from being drawn into the mixing tube and plugging it.
When working with a highly buoyant material such as wood or paper products, it may not be possible to
keep the abrasivejet nozzle under water. In this situation, always wear hearing protection and be
prepared for the additional over-spray during machining.
Place a Muff on the Abrasivejet Nozzle
The OMAX is shipped with a sponge muff that fits over the abrasivejet nozzle. This muff serves several
purposes. It keeps the noise level low during machining, reduces splashing and spraying, and protects
the Z-axis and cutting head components. Always place a muff on the abrasivejet nozzle when machining.
This muff will eventually wear out. Included with the OMAX software is a file called “Muff” in the
\SAMPLES\USEFUL_TOOLS
directory that contains the pattern needed for making additional muffs. Use
sponge material at least 1" (2.5 cm) thick for the muff. Muffs may also be ordered from OMAX.

Keep Extra Sponges on Hand
Extra sponges should always be available. Set the sponges in the tank around the material being
machined. When the abrasivejet stream strikes one of the support slats, often the stream is deflected
and water sprays. The sponges reduce the spray and are also handy for wiping down the work surface.
Washing Heavy Garnet Deposits from Parts
Garnet will be deposited on the surface a part while being machined. Because the abrasivejet nozzle
moves slowly and has time to stir up more sediment, this is most noticeable when working with thick
materials. When too much spent abrasive has accumulated, the abrasivejet nozzle will need to plow
through it, causing the material to shift and reduce the accuracy of the cut.
