Development

• For electrodes, electric conductivity and tensile strength are important as they are closely related with cutting speed and accuracy, respectively. Bronze has high electric conductivity and elongation and thus was first used for electrodes. Then, brass which has greater tensile strength came into use, making more accurate cutting possible. Cutting speed and accuracy were further heightened by using zinc-coated electrodes. In addition to these chemical improvements, OPECMADE made physical improvements by adding pores to the surface of electrodes.

High Speed Cutting

• Cracked Surface wires absorb more cooling water due to their enlarged surface area and cool down faster than the existing non-porous wires. This allows cracked surface wires much faster cutting speed.

High Accuracy and Fine Finishes

• Thanks to the cooling ability, OPECMADE cracking wires realize enhanced tensile strength when cutting and do not break easily. Therefore, comparing to other coated wires, they can fabricate workpieces with finer finishes and greater accuracy.
