How Does a Waterjet Work
Basic Components and Operation
High Pressure Pump
The pump generates a flow of pressurized water for the cutting process.
Articulated Cutting Head
As an add-on option to OMAX waterjets, this computer-controlled multi-axis cutting head permits angled cuts and can be used to automatically minimize taper for precise vertical cuts.
Abrasive Waterjet Nozzle
Inside the nozzle the pressurized water passes through a small-diameter orifice and forms a coherent jet of water. The jet then passes through a venturi section where a metered amount of granular abrasive is drawn into the water stream. The mixture of water and abrasive particles passes through a special ceramic mixing tube and the resulting abrasive/water slurry exits the nozzle as a coherent cutting stream of abrasive particles travelling at very high speed.
The water-filled catcher tank dissipates the energy of the abrasive jet after it has cut through the material being machined.
The abrasive hopper and associated abrasive flow control system provide a metered flow of granular abrasive to the nozzle.
X-Y Traverse System
A precision X-Y motion system is used to accurately move the nozzle to create the desired cutting path.
Advanced motion controllers for abrasive waterjet systems are PC-based and permit production of accurate parts with minimal operator experience.
