nesteileikkauksin

Nesteileikkauksin is a Finnish term that translates to "liquid cutting" or "waterjet cutting" in English. It refers to a subtractive manufacturing process that uses a high-pressure stream of water, often mixed with an abrasive material, to cut through various materials. This method is highly versatile and can be employed on a wide range of substances, including metals, plastics, stone, glass, and composites.

The core principle of nesteileikkauksin involves a pump that pressurizes water to extremely high levels, typically between 30,000 and 60,000 psi. This pressurized water is then forced through a small orifice, creating a narrow, focused jet. For cutting harder materials, abrasive particles such as garnet or aluminum oxide are introduced into the water stream just before it exits the nozzle. The impact of these high-velocity particles erodes the material, allowing the jet to cut through it.

Nesteileikkauksin offers several advantages. It is a "cold cutting" process, meaning it does not generate significant heat, which prevents thermal distortion or changes to the material's properties. This makes it ideal for heat-sensitive materials. The process also produces a clean edge with minimal burrs, often eliminating the need for secondary finishing operations. Furthermore, it is an environmentally friendly method as it typically uses natural abrasives and produces minimal waste. The precision and accuracy achievable with waterjet cutting make it suitable for intricate designs and demanding applications in industries such as aerospace, automotive, and manufacturing.
