FAQs
Also known as Electro Discharge Machining Wire Erosion, EDM is an engineering process known for the way it precisely creates components for specific projects.
The EDM process cuts contours in a workpiece with a wire strand used as an electrode. This creates electrical sparks between the workpiece and the wire during the machining process. The electrical sparks from the wire have a high level of control that ensures the cutting is as accurate as possible.
The workpiece is submerged in a dielectric fluid (normally deionized water). As well as working as a cooler, the fluid washes away the metal debris as it is cut, helping maintain the high level of accuracy required.
The process involves wire erosion, which mainly starts at the workpiece’s edge. It can also begin by drilling a hole precisely at the start of the process.
Suitable for challenging designs and materials
The process can create very complex shapes even when working with rigid and thick materials requiring extra work.
High precision
EDM is suitable for very small workpieces that could otherwise be damaged by conventional cutting tools.
Limited distortion
EDM prevents material distortion because the tool and workpiece don’t make contact. This makes EDM ideal for delicate sections with a precise design structure.
High quality finish
The process results in a perfect finish. Fine holes and tempered holes are both possible using this method.
