Q: What is WaterJet cutting?

WaterJet cutting employs a narrow stream of water at extremely high pressure to cut through almost any material. Usually, an abrasive is added to the stream to facilitate the cutting. The computer controlled cutting nozzle moves in an XY plane, and can make very precise cuts with intricate designs.

Q: What is the maximum size part that Portland WaterJet can cut?

The OMAX WaterJet that we use can cut a sheet up to 25” X 51”. Practically speaking, we can cut material up to about 1” thick. On thicker material the precision of the cut is diminished, but still possible up to 6 inches! We are limited to cutting flat stock material only. Please call or email for more information.

Q: What type of file can I use to create my design?

The OMAX waterjet has its own proprietary CAD/CAM software. Also, most major third party CAD/CAM software is supported by OMAX. The preferred file formats are DXF, DWG, SVG, and AI. These formats import cleanly and require little or no ‘design time’ to get them to a usable form. Files imported from other programs will likely require extra computer design time to adapt to the OMAX software. It is also possible to use hand-drawn designs, cardboard templates, photographs, etc. The OMAX software is able to trace these types of images, and from that we can make the necessary machine toolpath. Please call or email for tips and tricks regarding hand-made designs.

Q: How does WaterJetting compare to Laser Cutting?

WaterJetting does not heat the material

WaterJetting produces a clean cut that usually requires little or no secondary work

WaterJetting is not affected by reflective surfaces

WaterJetting is safer– produces no toxic fumes

WaterJetting has the same or higher tolerances
