1. Understanding Flow Waterjet Technology: The Core Advantage
When evaluating a Flow waterjet for sale, it’s vital to grasp the technological superiority that sets these machines apart.
Intensifier Pump Technology: Flow pioneered and perfected the ultra-high pressure intensifier pump. This robust system reliably generates pressures exceeding 60,000 PSI (and often up to 90,000+ PSI in newer models), creating the powerful, focused stream necessary for cutting through virtually any material. The durability and consistency of Flow pumps are legendary in the industry.
Dynamic Waterjet® XD Cutting Head: This proprietary cutting head technology is a game-changer. It dynamically tilts the cutting head to compensate for the natural taper (“kerf”) inherent in waterjet cutting, resulting in near-perfectly square edges on thick materials. This eliminates secondary machining operations on critical parts, saving significant time and cost.
Advanced Motion Control & Software: Flow machines are integrated with sophisticated CNC controls (often FlowXpert or compatible systems) and user-friendly software suites like FlowCut. These provide precise motion control, intuitive nesting capabilities, simulation tools, and seamless CAD/CAM integration, streamlining the entire cutting process from design to finished part.
Pure vs. Abrasive Waterjet: Flow systems can be configured for pure waterjet cutting (ideal for softer materials like rubber, foam, food, and gaskets) or abrasive waterjet cutting (using garnet abrasive mixed into the stream to cut metals, stone, composites, glass, and ceramics). Many machines offer easy switching between modes.
Purchasing a Flow waterjet for sale means investing in this proven, cutting-edge technology foundation.
