Wire EDM is a machining process that uses electrical discharges to remove conductive material such as metal. With a variety of wire EDM machines such as our Wire Feed EDM, Auto Threader, and Small Hole EDM, Coulson Precision Tooling provides a variety of wire EDM services. For more information on our machines, be sure to visit our Photo Gallery and Machine Specs pages. Coulson Precision Tooling currently operates 3 Charmilles Robofil Wire EDM machines: a 290 Auto Threader Wire Feed EDM, a 290 Wire Feed EDM, and a 300 Wire Feed EDM. Coulson Precision Tooling's Wire EDM capabilities allow for for our high productivity and accuracy, assuring you of the most accurate, up to date machining possible. Wire EDM allows us to cut complex parts both in 2 and 4-axis. We currently use .006, .008, .010, and .012 inch diameter wire. Our smallest wire, the .006 wire, allows us to cut very fine, detailed parts with great accuracy, while our largest wire, the .012 wire, is used for speed. The .008 & .010 inch diameter wires are our standard sizes. Wire EDM enables us to cut a wide variety of complex parts, from parts with holes as small as .018 to adaptor and transition plates with 30-degree tapers. Our capacities permit up to 30-degree taper cuts at 15.750 thickness. Additionally, our sink type EDM services provide great flexibility in the creation of large and small tooling parts. Wire Feed EDM One of our specialties is designing and cutting streamlined adaptors for the plastic extrusion industry. The Charmilles Robofil 300 Wire Feed EDM (pictured on the right) allows us to cut up to 30-degree tapers at 15.750 inches. When combined with our programming system CT Esprite, shown on our CAD-CAM page, we can create extreme 4-axis programs (see graphic below). The graphic to the left is an example of a product designed with our CAD extreme 4-axis programming capabilities and created with one of our Wire Feed EDM machines. For more information on our wire feed EDM machines, see our machine specs. For more pictures of our wire feed EDM machines, view our photo gallery. Auto Threader The Auto Threader on our Charmilles Robofil 290 allows for multi-cavity parts, which can be set up during the day and left to run throughout night, increasing productivity and decreasing lead-time. This machine allows us to cut 30-degree tapers at an 8 inch thickness. Small Hole EDM/Hole Popper This machine allows us to drill holes as small as .012 and as big as .118, with a capacity as deep as 12 inches. With our hole popper we can drill through a variety of materials both hard and soft: hardened tool steels, carbide, copper, brass, and graphite. When used in conjuction with our Wire EDM machines, we can machine multi-cavity parts.
