Michael Waltrip Racing (MWR) has increased waterjet cutting productivity and has reduced costs by powering its waterjet system with Jet Edge’s 100HP 90,000lb/in2 X-Stream waterjet intensifier pump.

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

‘As an example, our spindles, which are one of our more complicated steering parts and cut from 2in (50.8mm) 4140 steel, used to take 50-55 minutes to cut at 60,000lb/in2.

‘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.

‘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.

‘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 1.5in thick steel and took about one 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 90,000 lb/in2 pump.’ These increased cutting speeds have allowed MWR to reduce its waterjet operating hours from between 60 and 65 hours a week to between 40 and 50 hours, saving on labour and overheads.

By freeing up production time, Jet Edge’s X-Stream waterjet pump has also helped MWR develop a side-business building cars for other race teams.

According to Hughes, MWR waterjets 250 parts for each of its race-cars.

The parts are cut from a variety of materials, ranging from 1/4in Nomex to 1/2in steel, and include numerous panels, mounts and chassis components, plus duct work, windows, splitter panels and more.
