Overview
The Flow NX Pro is Flow International's premium waterjet cutting platform, engineered for shops demanding the highest positioning accuracy and cutting performance in the waterjet industry. With linear positional accuracy of +/- 0.0127 mm (+/- 0.0005 in) and repeatability of +/- 0.02 mm (+/- 0.0008 in), the NX Pro delivers precision that approaches CNC milling territory while maintaining waterjet's signature ability to cut virtually any material without heat-affected zones.
The NX Pro is available in four table configurations ranging from the 2020 (2 m x 2 m) up to the 4040 (4 m x 4 m), providing work envelopes suited to everything from precision medical components to large aerospace panels. Rapid traverse speed reaches 17.8 m/min (700 in/min) with 0.1 g acceleration, enabling aggressive cutting speeds that minimize non-productive motion. Z-axis travel options of 305 mm (12 in) or 610 mm (24 in) accommodate thick materials and 3D cutting applications.
Flow equips the NX Pro with the FlowXpert software suite, including FlowXpert Infinity, FlowCut, and FlowNest for complete CAD/CAM-to-cutting workflow. The machine features a variable frequency drive that delivers 10-30% energy savings compared to conventional waterjet systems, and an automated abrasive recycling system that reduces garnet consumption by up to 50%. These efficiency features substantially reduce per-hour operating costs, which is a major factor in waterjet economics.
The NX Pro supports Flow's full range of pump technologies including the HyPlex Prime, MotoJet, MotoJet X, and HyperJet at up to 94,000 PSI (6,500 bar). Ballbar circularity of +/- 0.0635 mm (+/- 0.0025 in) ensures accurate contour cutting on complex profiles. The machine competes with the OMAX 80X series, Bystronic ByJet Flex, and WardJet Z-Series in the premium waterjet segment. New NX Pro systems price between $250,000 and $500,000 depending on table size, pump selection, and cutting head options.

Strengths & Limitations
Strengths
- Best-in-class positioning accuracy of +/- 0.0127 mm approaches CNC milling precision while maintaining waterjet material versatility
- Variable frequency drive and automated abrasive recycling reduce operating costs by 30-50%, significantly improving per-part economics
- 700 in/min rapid traverse with 0.1 g acceleration minimizes non-cutting time, improving productivity on multi-part nest layouts
- Support for HyperJet 94,000 PSI pump enables 30-50% faster cutting speeds compared to standard 60,000 PSI systems
- FlowXpert Infinity software provides advanced nesting, taper compensation, and material databases for optimized cut quality
- Four table size options from 2x2m to 4x4m accommodate a wide range of part sizes and production volumes
Limitations
- Premium pricing of $250K-$500K is significantly higher than entry-level Flow models like the Mach 150 or EchoJet
- HyperJet 94,000 PSI operation requires specialized maintenance expertise and higher consumable costs than standard 60,000 PSI systems
- Abrasive waterjet operating costs of $25-$45/hour remain higher than laser cutting for thin sheet metal applications
- Complex pump and high-pressure plumbing systems require more maintenance infrastructure than simpler waterjet platforms

Frequently Asked Questions
01
New NX Pro systems price between $250,000 and $500,000 depending on table size, pump selection, and cutting head options. A 3020 table with HyPlex Prime pump starts around $250,000. Larger 4040 tables with HyperJet 94,000 PSI pump and Dynamic Waterjet XD head reach $500,000. Operating costs run $25-$45/hour depending on pump and abrasive configuration.
02
The NX Pro offers superior positioning accuracy (0.0127 mm vs 0.0127 mm comparable), automated abrasive recycling, and variable frequency drive energy savings that the Mach 500 does not include as standard. The Mach 500 offers more table size options including very large formats up to 4x8m. Choose the NX Pro for precision and operating efficiency; the Mach 500 for larger work envelopes.
03
The NX Pro cuts virtually any material: metals (steel, aluminum, titanium, Inconel, copper), composites (carbon fiber, fiberglass), stone, glass, ceramics, rubber, foam, and plastics. Maximum cutting thickness depends on material — typically up to 200 mm (8 in) on metals with the HyperJet pump. Only tempered glass and diamonds cannot be cut.
04
Flow's automated abrasive recycling system collects used garnet from the cutting tank, separates reusable particles from waste, and returns them to the abrasive hopper. This reduces garnet consumption by up to 50%, saving $10-$15/hour in abrasive costs on typical operations. The system pays for itself within 6-12 months on high-utilization machines.
