Abrasive water jet cutting 3D

3D machining of curved surfaces by abrasion from a high-pressure water jet mixed with abrasives.

The process

Water under high pressure [1] of up to 4000 bar is focused through a nozzle [2]. Abrasive agents [3] are then supplied through the vacuum formed in the mixing chamber [4]. High pressure water jet charged with the abrasive agent then cut through the workpiece.

The cutting head is positioned usually by means of a portal system in combination with additional shafts to provide tilting and rotation. The systems are designed for 3D cutting of flat plates and to some extent also for cutting curved surfaces but does not have the same slant opportunities and working range for full 3D cutting.

Positioning can also be carried out by using a industrial robot if its positioning accuracy can fulfill the strived tolerances. Water mixed with debris is collected and filtered to partially able reuse the abrasive agent.
