Water Cutting Steel Psi

Faster feed rates are used to prevent the jet from cutting all the way through.

Water cutting steel psi.

Simply put the higher the pressure the faster the cut. Logarithmic scale comparing four sources of water in terms of upper pressure limits. 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.

To calculate your material cutting speed and waterjet pump pressure download the kmt 60 000psi 90 000psi cutting calculator on your computer. The actual cutting is often done under water to reduce splash and noise. The more water you flow the faster the cut. 55 000 psi water and it uses perhaps 0 8 lbs min of 80 grit garnet.

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. 50 hp pump 1 cutting head 60 000 psi 1 1 gpm water output. 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. 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.

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. 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. Fast extreme water jet cutter machine working modern technology waterjet cutting compilation. This is also why you rarely see production pumps that run more than 60 000 psi 4 100 bar.
