Navus Obtains Versatile Waterjet Cutting Machine


The machine’s 5-axis motion allows for accurate bevel, arc, and angle cutting.

The team at Navus Automation, Inc., is one of the first in the region to acquire a Flow waterjet cutting machine. The CNC (computer numerically controlled) cutting technology uses high-pressure water jets as well as an abrasive to precisely cut through virtually any material, from paper or aluminum to steel or even granite.

The waterjet can cut material from 1/16 inch up to 10 inches thick, in high or low volume. A hair-thin pure waterjet stream is ideal for cutting soft materials, while a mixture of water and a garnet abrasive deftly cuts any hard material. The machine operates with a 5-axis motion for accurate bevel, arc, and compound angle cutting.

The cold cutting process means the materials are not subjected to the stress of heat or a heat affected zone. The cuts produce accurate and smooth edges, with minimal secondary finishing required. Waterjet cutting yields a tighter tolerance than plasma and oxy-fuel cutting, with less pre-cut preparation work and no post-cut grinding or deburring. Specifically, the technology allows for:

  • A traverse range of up to 500 in/min [12.7 m/min]
  • A linear straightness accuracy of +/- 0.0015 in/3 ft [+/- 0.038 mm/m]
  • Repeatability of +/- 0.002 in[+/- 0.050 mm]

With the acquisition of the Flow waterjet technology, Navus engineers are able to improve cutting accuracy and quality. The Flow software suite allows for quick and precise programming for cutting a part of any material and any thickness, widening Navus’ range of overall capabilities, efficiency, and productivity. Industries Navus will be able to utilize the waterjet cutting technology for include:

  • Aerospace
  • Automotive
  • Shipbuilding
  • Energy
  • Oil & Gas
  • Agriculture
  • Architecture
