Benefits of Waterjet Cutting
Waterjet cutting stands out as one of the most versatile and material-friendly cutting methods available today. Its greatest advantage is the “cold-cutting process“. There is absolutely no heat-affected zone (HAZ), which means no thermal distortion, no material hardening, no microcracks, and no change to the intrinsic mechanical or chemical properties of the workpiece. This makes it indispensable for cutting heat-sensitive materials like aerospace alloys, hardened tool steel, tempered glass, and plastics that would warp or degrade under laser or plasma cutting. Second, unmatched material versatility allows a single machine to cut metal, stone, glass, ceramics, composites, rubber, foam, and even food, all without changing tools or optics, simply by adjusting the cutting speed and abrasive flow.
Waterjet Cutting Standard Tolerances
Standard abrasive waterjet cutting delivers typical dimensional tolerances of ±0.1‑0.25 mm per ISO 2768‑m norms. Precision drops as material thickness rises, bringing minor edge taper. Thinner workpieces can reach ±0.05 mm at slower feed rates. Kerf offset must be considered in CAD for accurate finished‑part dimensions.
Material Thickness |
Standard Tolerance |
Precision Tolerance |
|---|---|---|
0.5 – 6 mm (thin sheet) | ±0.05 mm (±0.002") | ±0.025 mm (±0.001") |
6 – 20 mm (medium plate) | ±0.10 mm (±0.004") | ±0.05 mm (±0.002") |
20 – 50 mm (thick plate) | ±0.20 mm (±0.008") | ±0.10 mm (±0.004") |
50 – 100 mm (heavy plate) | ±0.40 mm (±0.016") | ±0.20 mm (±0.008") |
100 – 200 mm (very thick) | ±0.80 mm (±0.031") | ±0.40 mm (±0.016") |
Waterjet Cutting Service Capabilities
Our waterjet cutting service uses abrasive waterjet for multi‑material parts. It delivers complex geometry and tight tolerance with no heat distortion. Accepts CAD files for prototypes and small‑batch production runs.
Pure waterjet cutting uses a high-pressure stream of water (up to 60,000 psi), forced through a small nozzle, to erode and cut soft materials like foam, rubber, textiles, and food. Unlike abrasive waterjet cutting, it contains no added abrasive particles, making it ideal for precise, contamination-free cuts on delicate or heat-sensitive materials.
Abrasive waterjet cutting mixes high-pressure water (up to 90,000 psi) with garnet or other abrasive particles to cut hard materials like metal, stone, glass, and composites. The abrasive boosts cutting power, enabling clean, precise cuts through thick, dense materials without heat-affected zones, making it ideal for industrial fabrication and precision machining applications.

Waterjet Cutting Materials
Waterjet cutting supports versatile material processing. Waterjet cuts metal, stone, ceramics and composites; pure waterjet slices soft foam, rubber and textiles. No heat‑affected zone eliminates thermal distortion. Brittle materials need stable fixturing. Tune abrasive grit and cutting speed to gain clean cuts for varied hardness and thickness.

Lead Time for Waterjet Cutting Service
Lead time for waterjet cutting service depends on part complexity, quantity and material availability. Simple custom‑cut parts usually ship within 2‑5 business days. Complex abrasive waterjet projects with large batches require longer production schedule. Material stock‑outs will extend turnaround. Rush order options are available for urgent waterjet cutting requests.

Parts with Surface Finishing | Add 3 – 7 business days | Add 2 – 4 business days |
Waterjet Cutting Surface Finishes
Waterjet cutting surface finishes vary with abrasive waterjet settings. Slower cutting speed delivers smoother edge quality; faster feeds produce coarser textures. No thermal burn occurs. Secondary finishing may be needed for high‑spec parts to remove slight taper and achieve precise surface requirements.
As-Fabricated
Best for sheet metal fabrication cutting, bending, and welding with no secondary treatment.
Brushed
Best for mechanical brushing with abrasive belts creates a uniform directional linear grain pattern
Polished
Best for mechanical polishing with progressively finer compounds and buffing.
Anodized
Best for electrochemical process creates a hard, corrosion-resistant, dyeable aluminum oxide layer on aluminum sheet metal.
Bead Blasted
Best for high-pressure blasting with glass beads or aluminum oxide creates a uniform matte satin, non-reflective surface.
Galvanized
Best for excellent long-term corrosion protection for outdoor and structural applications.
Passivated
Best for chemical treatment (citric or nitric acid) removes free iron and contaminants from stainless steel surfaces
Black Oxide
Best for Chemical conversion coating creates a uniform matte black finish on steel sheet metal.
Painted
Best for good corrosion protection and decorative color ideal for parts requiring custom color matching, intricate masking, or multi-color finishes.
