Machine Comparison
Flow Mach 300 vs Flow Mach 500
Flow International vs Flow International · CNC Waterjet
Summary
The Flow Mach 300 and Flow Mach 500 are both from Flow International's cnc waterjet lineup, making this a common upgrade or lineup decision for shops already invested in the Flow International ecosystem. The Flow Mach 500 leads in rapid traverse (17,800 mm/min (700 ipm) vs 15,240 mm/min (600 ipm)). These machines are closely matched across most specifications, making the decision more about specific feature priorities, dealer support, and your existing shop ecosystem than raw spec advantages. Both machines are proven performers in production environments and represent solid investments for shops in the market for a cnc waterjet.
Specifications Comparison
| Specification | Flow Mach 300 | Flow Mach 500 |
|---|---|---|
| Rapid Traverse | 15,240 mm/min (600 ipm) | 17,800 mm/min (700 ipm) ▲ |
| Repeatability | +/- 0.025 mm (0.001 in) | 0.025 mm (0.001 in) |
| Table Sizes | 1,500 x 1,500 mm to 4,000 x 2,000 mm | 2020 / 3020 / 3060 / 4020 / 4080 ▲ |
| Price Range | $200,000 - $400,000 (new) ▲ | $250,000 - $500,000+ |
Advantages
Flow Mach 300
- More competitive pricing at $200,000 - $400,000 (new) compared to $250,000 - $500,000+
- Backed by Flow International's dealer and service network for parts and support
- Production shops needing tighter tolerances than entry-level waterjets
Flow Mach 500
- Faster rapid traverse at 17,800 mm/min (700 ipm) reduces non-cutting time between operations
- Superior table sizes at 2020 / 3020 / 3060 / 4020 / 4080 vs 1,500 x 1,500 mm to 4,000 x 2,000 mm
- Backed by Flow International's dealer and service network for parts and support
- Production job shops cutting diverse materials (metals, composites, stone, glass) that need the fastest possible waterjet cutting speeds
Verdict
This is a close matchup. The Flow Mach 300 and Flow Mach 500 trade advantages across different specifications, making neither a clear winner on paper alone. Your decision should come down to practical factors: which dealer is closer, which control system your operators already know, what tooling ecosystem you're invested in, and which machine's specific strengths match your highest-volume work. Get quotes on both, run test cuts with your actual parts if possible, and factor in long-term service and support costs.
