What is Waterjet Cutting Machine? A Waterjet Cutting Machine is a machine tool uses a specific and a consistent high pressure pressurized water called waterjet which supplied by high pressure pump to cut or pierce variety of metal or non-metal materials.
CNC Waterjet Cutting Machine is consistently deliver an extremely high level of cutting precision, accuracy and performance that fully utilize the waterjet cutting technology which uses CNC G codes and CNC M codes to control the overall machie cutting process.
There are two type of waterjets used by Waterjet Cutting Machines to cut materials. There are Pure Waterjet and Abrasive Waterjet. A Waterjet Cutting Machine might used pure waterjet or abrasive waterjet or both method to cut almost any materials. Pure waterjet uses to cut a variety of soft materials such as paper, rubber, foam and baby diapers. The abrasive waterjet uses to cut almost any hard materials such as titanium, stainless steel, stone and glass.
How a Waterjet Cutting Machine Works?
How Waterjet Cutter works? Basically, the Waterjet Cutter or Waterjet Cutting Machine uses the technology of high pressurized water supplied by high pressure pump and delivers it consistently and continuously up to 90,000 psi or 6200 Bar (620 MPa) and forced it through a pre-mounted orifice or small hole as small as 0.005 inches (0.127 mm), it will create a jet stream called pure waterjet.
Pure Waterjet
If a small amount of abrasive material such as granet is mixed into the jet stream, it will create a jet stream called abrasivejet or abrasive waterjet. The jet stream flow exits the nozzle will make contact with the surface of workpiece. The workpiece will develop small cracks due to jet stream impact and propagate until the material is cut through.
