Do You Known Wire DEM?

What is Wire DEM？

Also known as spark eroding or spark machining, Wire EDM is a machining process where an electrically charged single strand wire is constantly fed within a dielectric fluid (usually deionized water) the resulting discharge when presented by the CNC in close proximity to the grounded workpiece is used to cut a conductive material.

How Does Wire EDM Machine Work?

Wire EDM machining（Electrical Discharge Machining）is an electro thermal production process where a thin single-strand metal wire, Conductive deionized water allows the wire to cut through metal by the use of heat from electrical sparks while preventing rust.

The working principle of the wire cut machine is to use a continuously moving thin metal wire (called the electrode wire) as an electrode, and then perform pulse spark discharge on the workpiece to remove the metal and cut the shape.

The wire EDM machining can process any material with hardness, strength, and brittleness, and is widely used.

The Five Benefits of Using a Wire EDM

1.Allows for the Formation of Complex Parts

Wire EDM machines can make different shapes, such as contours and holes, even on the hardest and the most fragile materials.

2. It Doesn't Need Mechanical Force.

Unlike a vast array of fabrication processes that use impact to cut through materials, Wire EDM leverages thermal discharges to cut through parts. This means that the end product will not be deformed, distorted, or have any side effects of deformation caused by brute force in material removal.

3.Cost-Effectiveness

When you use Wire EDM, you'll not have to use a lot of energy to cut even the most rigid materials. Additionally, you'll reduce material wastage since the process only removes the targeted particles only.

4. Accuracy and Precision

5. High Tolerance

The other benefit of Wire EDM is the fact that you can achieve high tolerance regardless of the material you’re working on. You can easily achieve tolerance of +/- 0.0005” with some machines that offer tolerances down to a few microns.

6. Improve production efficiency

The Advantage Of Wire EDMs

1. The process allows machinists to create intricate shapes and patterns.

2. Wire EDM can be used on both hard and relatively soft material without any deformation or distortions.

3. Make mold parts possess fine and smooth surface.

Common Application of Wire EDMs

1.Blanking punches and extrusion dies.

2.Automotive and aerospace parts and components

3.Implantable medical devices

4.Prototypes proof of concept builds

5.Small hole drilling on hard and soft materials
