Master Cut EDM

Master Cut EDM, which owns one of the largest wire EDM machines in the American Midwest, is uniquely positioned to handle some of the most challenging EDM wire work in the market. In this instance, our plastics industry client required a 30" X 50" size mold that would produce a high-pressure, plastic container. We were able to accommodate that large part by using electrical discharge machining on our over-size EDM machine which has the ability to cut a 50" X 36" X 20" fully submerged part. Our precision, high-tech Makino U86 wire EDM machine cut eight lifter pockets through various parts of the block. Those pockets sides were parallel to each other but not square to the block and were positioned 10° from the vertical. Master Cut EDM uses its EDM services and experience to maximize quality and significantly reduce job costs to the benefit of its customers whenever possible. On this cylinder mold, we achieved extremely tight tolerances of -.0000+.0002 and performed in-process testing and inspections. We also verified to +.0001 using certified gage blocks. Our round-the-clock service ensures the type of rapid turnar

Master Cut EDM's founders Harold Bartman and Scott Phillips have put their 60+ years of combined industry experience to work for our customers. Together, they've assembled a top-notch team of skilled and experienced metalworking specialists who match Master Cut machining solutions to our automotive, defense, medical, aerospace and packaging customers' requirements. When our client needed a tool steel headlight mold for an injection-molding application used in the automotive industry, we used wire electrical discharge machining on our state-of-the-art Makino U86 wire EDM. Part of Makino's award-winning U-series of wire EDM machines, the U86 offers true work-piece accuracy, superior surface finishes and faster cycle times. For this customer, the U86 cut pockets and round holes and produced tight tolerances of +-.0005 location and +-.0002 size. We confirmed that it met the customer-supplied specifications using gage pins and blocks. H-13 hardened tool steel was used because it stands up to extreme heat while also offering thermal fatigue shock and breakage resistance. In just three days, Master Cut wire electrical discharge machined two of the 5, 000 lb parts for delivery within Illinois.
