Water Cutting Steel Psi

One way to understand the sheer amount of pressure involved in waterjet cutting is to compare it with other water sources in terms of maximum pounds per square inch psi. Where as he s going 1 ipm thru 1 8 al that would be good for 3 of mild steel on our little machine if i recall correctly. Faster feed rates are used to prevent the jet from cutting all the way through.

Simply put the higher the pressure the faster the cut.

Water cutting steel psi.

The more water you flow the faster the cut. If you were looking at the 50 hp pump from the pump specification chart you would know that your pump puts out 1 1 gpm at 60 000 psi. The actual cutting is often done under water to reduce splash and noise. 50 hp pump 1 cutting head 60 000 psi 1 1 gpm water output.

To calculate your material cutting speed and waterjet pump pressure download the kmt 60 000psi 90 000psi cutting calculator on your computer. The term abrasive jet refers specifically to the use of a mixture of water and abrasive to cut hard materials such as metal or granite while the terms pure waterjet and water. A water jet cutter also known as a water jet or waterjet is an industrial tool capable of cutting a wide variety of materials using a very high pressure jet of water or a mixture of water and an abrasive substance. Fast extreme water jet cutter machine working modern technology waterjet cutting compilation.

The water pressure is typically between 20 000 and 55 000 pounds per square inch psi. Unfortunately as the pressure increases so does the cost and maintenance so this is not as simple as it seems. This is also why you rarely see production pumps that run more than 60 000 psi 4 100 bar. Water jet cutting is ideal for use in hazardous environments where heat and flames are restricted.

55 000 psi water and it uses perhaps 0 8 lbs min of 80 grit garnet. The water is forced through a 0 010 to 0 015 in diameter orifice hole in a jewel. Jet edge s mobile water jet cutting tools are used to cut a variety of unique materials including pipelines steel reinforced concrete reactor vessels and fabricated metal structures. Logarithmic scale comparing four sources of water in terms of upper pressure limits.
