Michael Waltrip Racing (MWR) reports that it has experienced dramatic water jet cutting productivity gains and cost reductions since powering its Jet Edge waterjet system with Jet Edge's 100hp 90,000 psi X-Stream waterjet intensifier pump in January.

"We've been seeing, across the board, a 35% improvement in cutting speed, plus we are using about 25% less garnet abrasive, and we have reduced our costs by 30%," said Nick Hughes, MWR's technical director.

"As an example, our spindles, which are one of our more complicated steering parts and cut from 2" 4140 steel, used to take 50-55 minutes to cut at 60,000 psi. Now we are cutting them in 30-44 minutes. Before we got the waterjet, it used to take three or four hours to rough cut them on a bandsaw. I also should note that about the same time we upgraded our pump, we changed suppliers for our spindle blanks. They use a much harder material that requires a slower cutting time. The X-Stream offset the increased cutting time.

"Another good example of a reduction in machining time would be our upper control arm plates that attach our front suspension arms to the chassis. These are cut from 1.5" thick steel and took about 1 hour and 25 minutes to cut two with the double heads and the old 60Kpsi pump. We can now cut two in about one hour with the double heads and the 90Kpsi pump."

Thanks to these increased cutting speeds, MWR has been able to reduce its waterjet operating hours from 60 to 65 hours per week to 40 to 50 hours per week, saving on labor and overhead, Hughes noted.

Hughes said he has been very pleased with Jet Edge's X-Stream waterjet pump and with Jet Edge's performance in general.

"We would absolutely, definitely recommend the X-Stream pump to others. The productivity improvements and cost savings are very measurable. Jet Edge's service has been fantastic and any components we've needed to get in have always been in stock. We have nothing to complain about."
