Cutting head components
The main components of the cutting head are described below. Note that some cutting head assemblies
include the on/off valve assembly while others do not. For more information on on/off valves, please see
On/off valve repair.
Nozzle body
The nozzle body has two main functions: it contains the high-pressure water, and it aligns and holds
the orifice assembly in the cutting head.
Orifice
The orifice creates the high-velocity water jet. The orifice and its precision-engineered mount provide
a wear-resistant and accurate orifice assembly. The mount is designed to automatically align the
orifice with the mixing tube. It will not swage or jam into the body, and no special tools are required
to install it.
Mixing chamber
The mixing chamber introduces abrasive into the water stream. Mixing chambers have a carbide
insert installed into the housing below the orifice. This insert helps protect the orifice from becoming
damaged due to splash back produced when the waterjet turns off. For easy access, orient the vent
on the mixing chamber toward the front of the machine.
Mixing tube
The ring on the upper part of the mixing tube—in conjunction with the collet, spacer, and nozzle
nut—sets the axial location of the mixing tube.
