Waterjet Cutting: a buyer's sourcing guide
Everything a procurement team should know before opening an RFQ for waterjet cutting: materials, tolerances, certifications and red flags.
Recent RFQs in waterjet cutting
Overview
Waterjet cuts virtually any material without heat-affected zone, including titanium, copper, stone and laminated composites up to 200 mm. Slower than laser, but unbeatable on thickness and heat-sensitive parts.
When to choose this process
Use when material is too thick or too heat-sensitive for laser, or when zero HAZ is mandatory (aerospace, medical).
Typical materials
- Titanium
- Inconel
- Aluminium up to 150 mm
- Stainless up to 200 mm
- Composites, stone, glass
Typical tolerances
±0.1 mm typical; ±0.05 mm with dynamic head; no metallurgical alteration.
Certifications to ask for
- ISO 9001
- EN 9100 (aero shops)
Frequently asked questions
Waterjet vs laser, when does waterjet win?
Above ~20 mm thickness, on titanium/copper, on composites, and when zero heat-affected zone is required by the spec.
Does waterjet leave a clean edge?
Yes — a satin matt finish, no burrs on thin sheet; on thick parts a slight bevel (~0.5°) is normal unless dynamic compensation is used.
