Precise cuts – without thermal alteration of the cut edges
In the production of parts in companies, precise cuts are always required to create exact shapes. Waterjet cutting is one way to effectively carry out this process. The waterjet generated by KAMAT high-pressure pumps also cuts materials that may be highly flammable and are not suitable for an alternative thermal cutting process.
Last but not least, a major advantage of the waterjet is that it does not introduce heat into the workpiece and thus does not manipulate the properties of the material.
Waterjet cutting is conomical and environmentally friendly thanks to energy efficiency
Industrial waterjet cutting does not require heat. As a result, this process ends up saving energy costs and thus offers high energy efficiency.

How does waterjet cutting work?
In water cutting, a jet of water is directed at a surface at high pressure, which produces the desired cuts by removing material. The most important factors affecting the cutting performance are the water pressure, the diameter of the nozzle and the nozzle distance to the material. The higher the pressure, the greater the cutting depth and cutting performance. A waterjet can also contain abrasive materials like sand or shell fragments to facilitate the cutting process.
To generate the fine water jet, nozzles with a diameter of 0.1 to 0.5 millimeters (0.004 to 0.02 inches) and a water pressure of up to 3,000 bar are used in addition to high-pressure pumps. During cutting, a feed device moves the water jet at a specific speed and at a desired distance along the cutting line.

Advantages of Water Jet Cutting
Water jet cutting offers several advantages over other cutting processes such as laser or plasma cutting. It impresses with its precision, material protection and environmental friendliness and is therefore used in various industries.
- High precision and clean cut edges
- Achieves cutting accuracies of up to 0.03 mm (0.001 inches)
- No burr formation or reworking required
- Ideal for complex geometries
- No thermal influence on the material
- No heat development – prevents warping or material changes
- Particularly suitable for heat-sensitive materials such as titanium, aluminum or plastics
- Versatility – suitable for almost all materials
- Cuts metal, ceramic, glass, stone, plastic and composite materials
- Ability to process even ultra-hard materials such as bulletproof glass or hardened steel
- Environmentally friendly and resource-saving
- No use of toxic gases or chemicals
- Water can be recycled and used in the circulation system
- Minimal material loss due to narrow kerf
- Efficient for single pieces and series production
- Fast and economical production of prototypes and small batches
- Can be automated for high production capacities
- No tool wear and low maintenance costs
- No mechanical contact between tool and material
- Longer tool life and reduced maintenance costs compared to milling or laser cutting machines
Clean Cutting of Various Materials Thanks to Supersonic Speed
In industrial water jet cutting of various materials such as concrete, metal, stone, marble, etc., it is important that the high-pressure pumps and high-pressure nozzles convert the pressure into a constant jet of water. This water jet hits the workpiece at supersonic speed and produces a clean, smooth cut with minimal kerfs.
