​​Hole Drill EDM uses an electrode tube to drill extremely small precision holes on an electrically conductive work piece at a very high speed. With a five-axis configuration, the hole drill machine can drill holes at any angle on an inclined surface work piece. This technology is widely used in many industries, including aerospace, energy, automotive, medical, mold and die.

At Applegate EDM, we utilize the latest equipment and capabilities to meet and exceed the needs of our customers, in providing provide superb wire EDM, sinker EDM, and hole drilling EDM services, as well as CMM inspection.

Wire EDM machines have been around since the 1960s. Technological advancements have made this non-traditional machining method preferable for complex shapes, intricate contours or cavities, and hardened metals.  Since the wire can be tilted, it's possible to make parts with taper or with different profiles at the top and bottom.  See examples in the Product Gallery.

Technology

​​Sinker EDM consists of an electrically charged three-dimensional electrode and work piece submerged in an insulating fluid, which are connect to a power supply.  Widely used in mold making, Sinker EDM offers high speed, high accuracy and low electrode wear, as well as very fine finishes.
