Technology Overview
What is Wire Cut ?
The only difference between a wire cutter and a standard EDM is that a wire cutter uses copper wire electrodes of thickness varying from 0.02 to 0.3 mm. When the material to be cut approaches the copper wire electrode, the electrode’s electrical charge tends to jump over to it, creating the spark needed to cut the material. Here the workpiece should be a conductive metal so that the electrode can produce the spark.
The hardened metal and alloys, which are challenging to cut with other machining operations, are machined using the wire cut method. Because wire cutting entails applying minimal stress and little to no change in mechanical properties, it is also a successful machining technique when consistent mechanical properties are required. In addition, parts with Complex geometries, hard metal with tight tolerance requirement, excellent surface finish, and fine holes are achievable with wire cut CNC machining method.
Working Principle of Wire Cut
A low conductive liquid media (dielectric-fluid) is placed between the wire electrode and the metal to be cut. Next, the electrode wire moves close to the workpiece,
The wire becomes the cathode and the workpiece the anode when the electric supply is turned on. Due to the release of ions from the workpiece and the wire, ions tend to accelerate, increasing their kinetic energy and temperature, which leads the dielectric fluid to conduct. A spark will be produced when there is a potential difference between the electrodes once dielectric fluid starts to conduct electric current. The spark erodes the material from the pre-set position. After that, it moves away along a computer-controlled path.
The movement of the cutting wire is multidimensional, allowing the workpiece to be cut on many faces with a single setup while instructions are being sent through the computer.
The process of Wire Cut
The electrode is accurately positioned by providing coordinate instructions on the CNC machine before processing the wire cut. Since every tool used in CNC wire cutting can detect contact, they all operate using the automatic edge and center locating feature.
The wire does not touch the workpiece during the CNC wire cut process; instead, a spark is produced to carry out the operation. Cutting wire that has been electrically charged will increase the electric field as it approaches the workpiece. When it reaches electrical breakdown, the die-electric material placed between them will spark. The workpiece will then start to degrade as the spark jumps across it. The wire is continuously sent through the operation so its erosion won’t affect the cutting process.
The guide that supports the CNC wire cutting machine can move along three axes and in the x-y plane. The CNC computer controls the workpiece and guides movements.
Wire EDM FAQs
What Is Wire EDM's Cutting Method?
Wire EDM uses a thin, electrically charged wire to cut through conductive materials. The wire is continuously fed through the workpiece, generating sparks that melt and erode the material along the programmed path. This process allows for highly precise cuts without direct contact between the wire and the material.
How Accurate is Wire EDM Machining?
TWire EDM is renowned for its high precision, capable of achieving tolerances as tight as ±0.0001 inches. This high level of dimensional accuracy is ideal for producing complex parts with intricate details, ensuring that even the smallest features meet exact specifications.
Is It Possible To Wire EDM Stainless Steel?
Yes, Wire EDM can machine stainless steel effectively. The process is well-suited for cutting hard materials like stainless steel, providing clean cuts with minimal thermal impact, which helps maintain the material’s integrity with low roughness Ra.
What Is the Difference Between EDM and Wire Cut EDM?
EDM (Electrical Discharge Machining) encompasses various processes that remove material using electrical discharges. Wire Cut EDM is a specific type of EDM that uses a thin wire as the electrode to cut through the material, whereas other EDM processes might use different types of electrodes or techniques for material removal.
What Are the Disadvantages of Wire EDM?
The primary disadvantages of Wire EDM include its slower material removal rate compared to traditional machining methods, and its limitation to only conductive materials. Additionally, the process can be more expensive due to specialized equipment and consumables like the wire(electrode) itself.
