What is Wire EDM?
Wire cutting is a high-precision machining technology that uses the principle of electric spark discharge to cut conductive materials. It uses a thin metal wire as an electrode to cut the workpiece material without contact, which is particularly suitable for the manufacture of complex shapes and high-hardness parts. It can process almost all conductive materials, such as cemented carbide, stainless steel and titanium alloy, and has the characteristics of high precision, high surface finish and no mechanical stress. It is widely used in mold manufacturing, aerospace and electronics.


How it Works?
The principle of wire cutting is based on the phenomenon of electric spark discharge. It is a non-contact processing technology that uses electrical energy to locally melt or vaporize metal materials. The following is a detailed description of its working principle:
Through this principle, wire cutting is widely used in precision processing of high-hardness materials, such as mold manufacturing, aerospace parts and the production of complex electronic components.
Features of Wire Cutting Parts
Wire-cutting parts have the following characteristics:
1. High precision: Wire cutting can achieve extremely high dimensional accuracy and fine surface quality, suitable for precision parts manufacturing.
2. Complex shape processing: It can process complex geometric shapes, narrow grooves and sharp angles to meet various design requirements.
3. Strong adaptability: It can process various conductive materials, including cemented carbide, stainless steel, titanium alloy, etc.
4. Small heat impact: The heat affected zone is small during processing to avoid material deformation or performance damage.
5. Non-contact processing: Through discharge cutting, there is no need to directly contact the workpiece, which reduces the impact of mechanical stress on the parts.
6. Material saving: The cutting gap is narrow, the material waste is small, and it is suitable for the processing of high-cost materials.

By default, sharp edges will be broken and deburred. For any critical edges that must be left sharp, please note and specify them in your drawing.

Wire EDM Materials
Wire cutting is mainly used for conductive materials. The following are the common types of materials that can be processed:
- Steel: carbon steel, stainless steel, tool steel, mold steel, etc.
- Aluminum and aluminum alloys: suitable for processing lightweight parts.
- Copper and copper alloys: such as brass and bronze, suitable for conductive parts.
- Titanium and titanium alloys: suitable for high-performance parts in the aerospace and medical fields.
- Nickel-based alloys: such as Inconel, high temperature and corrosion resistant materials.
- Cemented carbide: such as tungsten steel, suitable for high wear-resistant parts.
Surface Finish Options
After the parts are machined, surface treatment is applied to create a unique surface layer to meet the product’s hardness, corrosion resistance and appearance requirements. The choice of surface treatment depends on the material properties and application of the part.
Rapid Protos(RPS) offers the following surface treatment options for wire-cut metal parts:
