Overview
The Flow Dynamic Waterjet XL is Flow International's large-format 5-axis waterjet platform, combining the Dynamic Waterjet cutting head technology with an extended table envelope to serve aerospace, shipbuilding, and heavy industrial fabricators that process large plate and sheet stock. The system is purpose-built for shops that need both the scale of a large-format machine and the geometric complexity enabled by 5-axis tilting head capability.
At the heart of the Dynamic Waterjet XL is Flow's Active Tolerance Control (ATC) technology. Traditional waterjet cutting introduces taper error — a slight angle on the cut wall — that increases with material thickness and cutting speed. Flow's ATC system dynamically adjusts the head angle in real time as the machine interpolates the toolpath, compensating for taper and producing near-perpendicular cut walls without slowing the machine down. This eliminates a major source of secondary machining rework on precision parts.
The Dynamic head tilts up to 60 degrees from vertical, enabling bevel cuts, chamfers, countersink geometry, and compound angles all in a single waterjet setup. For aerospace structural components, marine hull sections, and architectural metalwork, this eliminates the need for separate milling or grinding operations to achieve complex edge geometry. The XL configuration provides table sizes up to 4,000 x 8,000 mm, accommodating full sheet or plate without repositioning.
Flow's FlowXpert CAD/CAM software integrates taper compensation models, bevel programming, and nesting into a unified environment. SmartStream motion control optimizes the relationship between cutting speed and head angle in real time, maintaining cut quality as geometry changes. The Dynamic Waterjet XL is available with HyperPressure pump options up to 94,000 psi for maximum cutting speed on thick exotic alloys.

Frequently Asked Questions
01
ATC is Flow's real-time taper compensation system. As the cutting head moves through the toolpath, ATC continuously adjusts the head angle to counteract the natural taper that abrasive waterjet produces, delivering near-perpendicular cut walls without reducing cutting speed.
02
Yes. The cutting head tilts up to 60 degrees from vertical, enabling full bevel, chamfer, countersink, and compound-angle cuts in a single setup. FlowXpert CAM software programs these complex geometries directly.
03
The XL configuration offers table sizes ranging from standard Mach-series envelopes up to 4,000 x 8,000 mm. Custom table configurations are available for applications requiring non-standard dimensions.
04
Both use Flow's high-pressure pump technology, but the Dynamic Waterjet XL emphasizes the 5-axis Dynamic cutting head with Active Tolerance Control as the primary feature. The Mach 700 is Flow's premium production waterjet platform; the Dynamic XL is specifically configured for large-format 5-axis work.
05
The standard configuration runs at 60,000 psi. Optional HyperPressure pump upgrades bring operating pressure to 87,000 or 94,000 psi for maximum cutting speed on thick titanium, Inconel, and other hard alloys.
