CNC Waterjet

CNC waterjet cutting machines are precision cutting systems that use a high-pressure jet of water, with or without abrasive, to cut a wide range of materials accurately and without heat distortion. They are widely used where material integrity, edge quality and dimensional accuracy are critical.

Industrial CNC Waterjet Cutting Machines for Cold Cutting of Metals, Composites and Specialist Materials

Waterjet cutting is suitable for metals, composites, plastics, rubber, foam, stone and other specialist materials. As a cold cutting process, it produces no heat-affected zone, making it ideal for sensitive, laminated or thickness-critical materials that cannot be cut using thermal methods.

Typical Waterjet Cutting Applications

CNC waterjet cutting systems are widely used where materials must be cut accurately without generating heat distortion, including:

Aerospace composite and metal components
Defence specialist materials and engineered parts
Marine structural components and fabricated parts
Fabrication workshops processing varied material types

Waterjet cutting is suitable for processing materials including:

CNC waterjets support both one-off production and repeat batch work, offering flexibility across varying material types and thicknesses. With appropriate specification, they can deliver clean edges, tight tolerances and complex profiles within multi-material production environments.

Daltons supports CNC waterjet users through application-led machine selection, professional installation and commissioning, certificated operator training, and ongoing service and technical support across the UK and Ireland.

CNC Waterjet FAQs

CNC waterjets are used to cut a wide range of materials accurately without generating heat. They are commonly used for complex shapes, tight tolerances and materials that are sensitive to thermal distortion.

Waterjets can cut metals, composites, plastics, rubber, foam, stone, glass and specialist laminated materials. Cutting capability depends on whether pure water or abrasive waterjet cutting is used.

Pure waterjet cutting is typically used for softer materials such as foam, rubber and plastics. Abrasive waterjet cutting introduces an abrasive material into the water stream, allowing harder materials such as metals, stone and composites to be cut effectively.

No. Waterjet cutting is a cold cutting process, meaning there is no heat-affected zone, distortion or change to material properties.

Yes. Waterjets are capable of cutting both thin and thick materials, depending on machine specification and cutting parameters.

Yes. Operators must be trained to use CNC waterjet machines safely and effectively. Daltons provides certificated operator training to support safe operation and compliance.
