What waterjet cutting covers
Waterjet cutting uses a high-pressure (60,000-90,000 psi) stream of water — often with abrasive garnet added — to cut materials with no heat-affected zone, no thermal distortion, and no edge hardening. Two main variants: abrasive waterjet (for metals up to ~10" thick, stone, ceramics, composites) and pure waterjet (for soft materials — gasket, foam, plastic). California shops cover a wide range of capabilities, from job-shop sheet work to large-format 5-axis abrasive jets for stone and architectural panels.
What to look for in a supplier
Match the equipment to the part: 4'×8' tables are standard for sheet work; larger tables (5'×10', 6'×12') for big plate; 5-axis jets for tapered or 3D-contoured cuts. Material matters — abrasive jet for steel, stainless, aluminum, titanium, stone, glass; pure jet for soft materials only. Edge quality varies by feed rate: "quality 1" is rough (used for material removal); "quality 5" is mirror-smooth (used for parts that ship as-cut). Confirm the supplier accepts your file format (DXF, DWG, AI, STEP), tolerance class (±0.005" is standard, tighter is possible at slower speeds), and material-thickness range.
FAQ
Common questions
What's the maximum thickness for waterjet cutting?
Steel and stainless: up to 10" practical, 12" possible at slow feed rates. Aluminum: up to 12". Titanium: 6". Stone and ceramics: 6". For thicker material, plasma or oxy-fuel cutting is more economical, but they introduce heat-affected zones that waterjet doesn't.
What tolerance can waterjet hold?
Standard commercial tolerance: ±0.005" on thin material, opening up to ±0.015" on thick (>2"). Tight-tolerance work (±0.002") is achievable with precision machines, controlled tapering, and slow feed rates — comes at 2-3× the standard pricing.
Why use waterjet vs. laser?
Waterjet has no heat-affected zone, so it doesn't affect material properties — important for reflective metals, hardened steel, and stress-sensitive alloys. Waterjet also handles much thicker material than laser. Laser is faster on thin sheet and has narrower kerf — better for tight-pattern work in <0.5" sheet. Choose based on thickness and material sensitivity.
What file format do waterjet shops want?
DXF is the universal standard — vector-only, no fills, layers segregated for through-cut vs. etch. Most shops also accept DWG, AI, and increasingly STEP for 3D parts. Avoid raster formats (JPG, PNG) — they require conversion that introduces error.
