Water jet cutting is a process that uses a high pressure and speed jet of water to cut a wide variety of materials. According to the material to be cut there are two principal types: pure waterjet that uses only water and abrasivejet which use a mixture of water and abrasive to cut hard materials.
The equipment required for this process consists of a pool of water, nozzle, cooling center, warehouses for abrasives, decalcification, and a purifier of abrasives.
The two most important elements in the process are water cutting nozzle and pressure. Water mixed with the abrasive component necessary exits a nozzle at a pressure very high. The shape of the nozzle directly affects the accuracy and quality of the jet. The water pressure must be strong enough to produce the cut.
This process has got many advantages such as:
High quality cutting.
Versatility, the same machine can cut a wide range of materials.
Enviromentally friendly.
Cold cutting: no heat-affected zones.
Multi-axis cutting.
Stress-free cutting.
No produce dust or contaminant gases.
This operation hasn’t got notable disadvantages
