Tight Nesting Reduces Waste, Handling
Those who are familiar with abrasive waterjet cutting know that the absence of heat affected zones and toxic fumes are significant advantages of the process. But tight nesting of parts, speed, and lower overall costs are also benefits that can spell the difference for outsourcers who are seeking a machining process with fast turnaround. According to Steve Miller, president of Milco Wire EDM/Waterjet, abrasive waterjet cutting costs less overall because of faster production rates and the ability to provide "optimal part positioning and nesting," which reduce wasted material and the handling of parts. Abrasive waterjet is also an excellent alternative to laser cutting, flame cutting, plasma cutting, and even wire EDM in some cases, Miller says.
"If the tolerance is 0.005 inch or greater, our waterjet machines could work for you," says Miller. With a cutting area capacity of up to 55 inches x 100 inches, Milco's waterjet machines cut parts up to 4 inches thick and 4000 pounds in weight. The company can hold tolerances to 0.005 inch on materials up to -inch thick, and to 0.010 inch on materials up to 1 inch thick, Miller says.
In addition to its abrasive waterjet capabilities, Milco Wire EDM/Waterjet offers full CNC machine shop services along with highly accurate wire EDM, CNC sinker EDM, and EDM hole burning. For higher-tolerance parts, the company uses wire EDM technology to hold tolerances to 0.0002 inch at its temperature-controlled, 14,000-sq-ft production facility. The process can be used to cut conductive materials that include exotic metals, such as titanium, Kovar, Inconel, and hard tool steels.
