Water jet deburring is a precise process for removing burrs using a high-pressure water jet. Water is forced through a nozzle with a diameter of 0.1 to 0.5 mm at a pressure of up to 4,000 bar. The fine jet removes burrs in a targeted manner without subjecting the component to thermal or mechanical stress.
For harder materials such as steel, titanium or ceramics, an abrasive is added to the water, usually garnet sand with a grain size of 80 to 200 µm. This increases the cutting force so that even high-strength materials can be deburred precisely. The material removal is between 0.01 and 0.1 mm, depending on the pressure and beam focus.
The process is suitable for workpieces with wall thicknesses of 0.2 to 50 mm and is ideal for sensitive structures, fine bores or internal contours that are difficult to access. Even complex components can be processed evenly, reliably, efficiently and without material deformation using waterjet deburring.
