High Energy Applied Technology(H.E.A.T.) has been tested against other major EDM brands. In almost every case, it has been proven to burn at least 15 percent faster, produce part straightness of .0005 inches in one roughing pass and .0002 inches with one rough and one skim, in parts up to 12 inches tall, and provide better surface finishes with fewer skims.

Results have been documented in real life machining applications where H.E.A.T. technology was up to 52 percent faster than other available technologies. This means that not only is a machine equipped with H.E.A.T. capable of decreasing process time and increasing production throughput, but it also will use far less wire than other machines on the market for making the same parts.

Applications and Limitations

H.E.A.T. was developed with specific targets in mind. This technology can be used with commonly available brass or coated EDM wire of .010″ and .012″ diameter, but H.E.A.T. wire has also been developed, which shows an increase in cutting performance over standard wire using H.E.A.T. of up to 25 percent.

Developed for all standard tool steels, H.E.A.T. also has seen great success in titanium and Inconel applications. Part thick-ness for successful use of this technology ranges from 1 to 12 inches. As indicated previously, it is best suited for jobs that have uneven surfaces, varying thickness, interrupted cut paths and stacked plate work—any application that will have poor flushing conditions where the nozzles cannot be sealed against the work surface.

For flat plate work—such as precision ground stamping die plates where the flushing nozzles can be sealed—H.E.A.T. will not show any advantage over similar technologies. The advantage of using its settings on flat plate applications is in the setup time for this type of work. By using H.E.A.T. for flat work, less thought can be given to clamping or workholding getting in the way of the upper and/or lower heads in the cut path.
