Waterjet cutting: effective, flexible and precise For a variety of materials and cutting thicknesses of 0,1 - 300 mm.

Pure water cutting details
STM pure water system in action.

Waterjet cutting is one of the fastest growing industrial manufacturing processes. Especially the versatile fields of application, ease of use and effectiveness increases convince users of a wide range of different industries to integrate STM water jet cutting systems in their production processes. The technology of water jet cutting allows to cut almost any material. Therefore, STM systems can be found in tool- and mould-making, the automotive, aircraft or aerospace industry, as well as in the stone and tile sector, the metal construction sector and the contract manufacturing.

The technology of waterjet cutting

With waterjet cutting, water is pressed through a nozzle with a pressure of 4000-6000 bar. Resulting in enormous speeds, the water exits at Mach 2, with 2-fold air-speed of sound. The advantage is that the workpiece surface remains nearly cold because the cut is immediately cooled by the water. While waterjet cutting, there are no prestructural changes, increased hardness or noxious fumes.

Clean water cutting

Schema for pure water
Principle of pure water cutting

The pure water jet cuts soft materials such as foam and rubber. It is also used in the food industry.

The benefits of the pure water section:

  • Very thin beam (normal range of 0.1 to 0.25 mm)
  • Extremely detailed geometry
  • Very low material loss by cutting processing
  • Simple clamping

Abrasive waterjet cutting

Schema Abrasiv
Prinzip Abrasiv-Schneiden

If abrasive (garnet) is added to the water after the water nozzle, hard materials such as glass, metal, composites, etc. can be cut up to a thickness of 300 mm. Generally, it can be said that  with the abrasive waterjet it is possible to cut  materials to the hardness of the abrasive (Mohs hardness of about 8).

The advantages of abrasive waterjet cutting:

  • Extremely versatile process
  • No heat affected zones
  • No mechanical exposure
  • Thin beam (0.5 to 1.3 mm in diameter)
  • Hardly or no burrs
