Waterjet / Profile Cutting


Graham Engineering currently operate Northern Ireland’s only 4 meter x 2 meter Flow Waterjet cutting machine with 96000 psi cutting pressure allowing us to offer the best quality in cutting work in a variety of materials up to 6 inches thick.

Waterjet unlike Laser cutting will not effect the material being cut and will allow thicker materials to be cut. We also offer a sub contract profile cutting service throughout N.Ireland – Republic of Ireland and the UK. Waterjet cutting can offer better edge quality and tighter tolerance over plasma cutting.

As one of the worlds leading steel cutting machines Flow Waterjet overcomes the need of the customer in terms of profile cutting virtually any material.

Waterjet / profile cutting is used to cut a wide range of materials from the hardest titanium to the softest of foams to a very accurate, high quality finish. Any profile or design generated in Cad software can be transferred to our 3 axis Flow Waterjet machine and can cut through material up to 6 inches thick using a jet of water at high velocity and pressure, or a mixture of water and an abrasive substance. The process is essentially the same as water erosion found in nature but greatly accelerated and concentrated. It is often used during fabrication or manufacture of parts for machinery and other devices. It is the preferred method when the materials being cut are sensitive to the high temperatures generated by other methods. It has found applications in a diverse number of industries.

Graham Engineering’s flow waterjet can profile cut hardox, titanium faster  and  more economical than other conventional brands of waterjets.

A list of materials that can be watercut:

Stainless Steel                  Tool Steel                Polyethylene                 Ceramic

Mild Steel                           Titanium                  Copper                          Acrylics

Aluminium                          Brass                      Rubber                          Exotic Metals



Being one of the first companies in Northern Ireland to provide this service the benefits to the customer of water cutting are:-Flow Mach3

  • Cost effective for low volume batching
  • No tooling expenditure
  • Produces highly accurate components +/0.1
  • Our correction head 7 tilt improves edge quality with no taper unlike any other form of profile cutting
  • Cold cutting, will not effect material being cut
  • Ideal for prototype components
