WATER JET CUTTING: THE TECHNOLOGY

A collection of waterjets shoot water out of a nozzle at high pressure (up to 5,000 bar) on to the material. An abrasive medium (garnet sand) is added to the water to improve the cutting performance. This jet acts like a thin, round diamond saw blade but doesn’t heat the cutting edges. State-of-the-art CNC controls determine the course of the cutting contour.  Water jet cutting is a versatile and environmentally friendly cold cutting process.

Material processing

Water jet cutting processes can be used on just about any material, even titanium, steel and aluminium. Nearly all plastics and compounds can be machined without impacting the environment or releasing any noxious cutting vapours.  Grooves, holes and shapes can be cut into glass, laminated glass and ceramics in a single operation without scratching the material. There are now no limits to what artistic inspiration can create out of marble, granite, natural stone, ceramics etc.

The advantages

  • The cold cutting process guarantees that all materials can be cut without being deformed in any way, i.e. the cutting edges of the materials are not affected by heat and there are no changes to the material structure.
  • Any shape at all can be cut using this process and the cut can begin and end at any point on the surface of the workpiece.
  • No direct contact pressure on the material means that despite the high kinetic energy involved the material itself is not deformed, and the cutting is extremely accurate without frazzling or burrs. The surface of the material is not damaged during the process.
  • The fine jet allows for precise, accurate, high-quality cutting, and can create delicate and complex shapes.
  • Difficult materials, such as plastic-coated metal sheets, aluminium, copper, stainless steel etc. can be cut easily.
  • As the cutting process is clean without any cutting or grinding dust, filings or air pollution, the process is particularly environmentally friendly.
  • Costs can be reduced by producing individual pieces and prototypes cost effectively.
  • Programming costs are lowered by directly importing your data files (e.g. .dxf)
