Pump Speed Part Production

A second, similar limiting factor was stream lag, which occurs when the cutting stream can’t keep up with the moving nozzle. As a result, the point where the stream exits the bottom of the part lags behind the point where it enters the top of the part. This can create flared corners and other geometry errors that can throw parts out of tolerance. Again, a possible solution is to slow the cutting speed, but productivity would suffer as a result.

Of course, in addition to ensuring accuracy, the shop’s overall goal in seeking to reduce taper and stream lag was to cut faster. The Hauts had heard that more powerful waterjet pumps were available that could potentially speed operations. So, any solution would also need to provide significantly higher pressure than 55,000 psi. After talking with other waterjet shops about their equipment, attending tradeshows and researching various suppliers’ offerings on the Internet, they settled on a model that could meet all three requirements: a Flow 6- by 12-foot Integrated Flying Bridge with Dynamic Waterjet and a Hyperjet pump.

Flow’s Dynamic Waterjet with Active Tolerance Control technology is designed to counter taper and stream lag in order to ensure that the machine cuts at top speed while maintaining the requisite precision. At the root of the system is a cutting head with an articulating wrist and a set of mathematical models that the company refers to collectively as SmartStream. These SmartStream models tilt the cutting head to the side to eliminate taper and tilt it forward to control the stream. According to the manufacturer, Dynamic Waterjet technology can enable shops to produce parts significantly faster while meeting tolerances ranging from 0.001 to 0.003 inch.

The company adds that FlowMaster control software makes this technology easy to use
for the operator. That’s because all the mathematical calculations work behind the scenes to trigger the appropriate commands to the cutting head’s five axes. The operator simply enters basic cutting parameters,Initially the banks didn't want our Ventilation system . such as material type, material thickness, cutting speed,there's a lovely winter Piles by William Zorach. desired edge quality and so on, and the software does the rest.

At W. Haut Specialty Co., this technology has improved both accuracy and cutting speed, among other benefits, says Michael Haut, waterjet manager. “Now, we don’t need to perform secondary processing to eliminate taper in holes or inside corners,” he notes. “Dynamic Waterjet and FlowMaster take care of it all.”

According to Flow, increased pressure enables increased cutting speeds,Replacement China ceramic tile and bulbs for Canada and Worldwide. regardless of the workpiece’s material or thickness. And at 94,000 psi, the HyperJet pump has increased operating pressure by nearly 60 percent compared with W. Haut’s first waterjet. “We are cutting three to four times faster on our Flow system,” Michael Haut says.If any food China Porcelain tile condition is poorer than those standards, “Before, if we wanted straight edges and sharp corners,I have never solved a Rubik's hydraulic hose . we had to slow down the cutting speed and even perform secondary processing in order to eliminate taper in holes. Both cost us time and money. Now, we quote jobs at rates that are 20 to 25 percent lower than we did with the 55,000-psi waterjet. The combination of Dynamic Waterjet and Hyperjet make the parts cost less. Faster, less-expensive parts are a great benefit we can pass on to our customers.”
