Pure Waterjet cutting forces ultra-high pressure water (up to 60,000PSI / 413 MPa) generated by Fedjet Trend Pro Series Pumps through a micro gem orifice (synthetic ruby or diamond) ranging from 0.08 mm to 0.25 mm.
Abrasive Waterjet cutting introduces solid 80-mesh Garnet Sand into a vacuum mixing chamber inside the cutting head. Accelerated through a tungsten carbide tube (0.76 - 1.02 mm ID), kinetic energy removes hard materials with zero Heat-Affected Zone (HAZ).
| Parameter | Pure Waterjet Cutting | Abrasive Waterjet Cutting |
|---|---|---|

| Orifice / Nozzle Size | 0.08 mm - 0.25 mm (0.003" - 0.010") | Orifice: 0.25mm + Carbide Tube: 0.76-1.02mm |
| Abrasive Media | None ($0 Consumable) | Garnet Sand 80 Mesh (0.25 - 0.50 kg/min) |
| Kerf Width (Cut Width) | 0.1 mm - 0.3 mm (Ultra-fine) | 0.8 mm - 1.2 mm |
| Edge Roughness ($R_a$) | $R_a$ 1.6 $\mu$m - 3.2 $\mu$m (Non-frayed) | $R_a$ 3.2 $\mu$m - 12.5 $\mu$m (Speed adjustable) |
| Component Lifespan | Diamond Orifice: 800 - 2,000 Hours | Carbide Focusing Tube: 100 - 150 Hours |
| Recommended Fedjet System | SmartJet / PowerJet Pure Series | PowerJet 5A-Taper10 5-Axis Series |
Filter materials below to inspect cutting suitability and recommended process:
High-speed contour cutting up to 30 m/min with zero thermal scorching or material distortion.
Cuts steel up to 150mm thickness. Eliminates Heat-Affected Zone (HAZ) and edge hardening.
No physical compression deformation; clean, dust-free edges with tight nesting density.
Prevents thermal stress micro-cracks; maintains critical structural material grain boundaries.
Requires Fedjet dual-pressure piercing control to prevent composite sheet delamination.
Enables delicate inlay medallion architecture with zero micro-fracturing under low pressure.
Includes power, water, gem orifice wear, carbide focusing tube, and garnet sand consumption benchmarked on Fedjet Trend Pro Systems.
