The highly flexible and efficient high-pressure water jet deburring system enables deburring and cleaning with a water pressure of around 500 bar in one work step. The rotary table integrated in the treatment chamber of the new system with pneumatic connections for automatic workpiece clamping devices is designed for components with a diameter of up to 450 mm and a maximum height of 550 mm. The maximum workpiece weight including the clamping device is 100 kg. These dimensions make it possible to handle, for example, an engine block for a four- cylinder engine or several small parts. The water jet generated in the high- pressure unit with a pressure of up to 500 bar is passed through a four-way nozzle system with automatic nozzle switch.
