Vattenstråletrimning

Vattenstråletrimning, often referred to as waterjet trimming or simply waterjetting, is a subtractive manufacturing process that uses a high-pressure stream of water to cut through materials. The water is propelled through a nozzle at extremely high speeds, creating a powerful cutting jet. This jet can be pure water, or it can be mixed with an abrasive material, such as garnet, for cutting harder substances.

The process is highly versatile and can be used to cut a wide range of materials, including metals, plastics, composites, stone, glass, and rubber. The precision of waterjet trimming allows for intricate shapes and tight tolerances to be achieved. Unlike thermal cutting methods, such as laser or plasma cutting, waterjetting does not generate heat, which means there is no heat-affected zone (HAZ) on the material being cut. This is particularly advantageous when working with heat-sensitive materials.

The abrasive waterjet cutting technique is employed for materials that are too hard for pure waterjetting. The abrasive particles, mixed with the water stream, erode the material's surface, enabling efficient cutting. The control over the process is typically managed by computer numerical control (CNC) systems, allowing for automated and repeatable cutting operations. Vattenstråletrimning is valued for its accuracy, clean cuts, and ability to process diverse materials without altering their inherent properties through heat.
