Wire Cut EDM is a high-precision processing equipment that uses the principle of electric spark discharge and thin metal wire (molybdenum wire or copper wire) as an electrode to perform two-dimensional or complex surface cutting on workpieces. It is widely used in mold manufacturing, precision parts processing, aerospace, medical equipment, automobile and other industries.
Wire cutting machines have the following characteristics:
1. Non-contact processing
No cutting force, suitable for processing high-hardness metals (such as hardened steel, cemented carbide, etc.).
2. High precision
The accuracy of slow wire cutting equipment can reach ±2μm, suitable for precision mold manufacturing.
3. High efficiency
Fast wire cutting is suitable for large-scale rough processing, and medium wire cutting has both efficiency and precision.
4. High degree of automation
Can realize CNC programming, graphic import, multiple cutting and other functions.
5. Strong adaptability
It can process complex cavities, microstructures, special-shaped parts, etc.
Wire cutting machines are widely used in industries such as mold manufacturing, aerospace, medical equipment, automotive industry, electronics and semiconductors, and precision machinery.
Next, the engineers of Shanghai ANTS Machiner Equipment Co., Ltd. will give you a detailed introduction on the application of wire cutting machines in different industries:
| Application Areas | Specific introduction |
Mold manufacturing | Stamping dies: Processing precision dies, progressive dies, etc., especially hard alloy dies after quenching. Injection molds: Manufacturing complex cavities, inserts and fine textures. Die-casting molds: Processing high-temperature resistant alloy molds, such as aluminum/zinc alloy die-casting molds. |
Aerospace | Engine parts: cutting turbine blades, combustion chamber parts and other high-temperature alloys (such as nickel-based alloys). Structural parts: processing titanium alloy frames, landing gear parts and other lightweight and high-strength materials. |
Medical Devices | Surgical instruments: manufacturing precision scalpels and orthopedic implants (such as titanium alloy joints). Minimally invasive equipment: processing small and complex structures such as thin catheters and endoscope metal parts. |
auto industry | Transmission system: precision finishing of gears and bushings. New energy components: motor silicon steel sheet molds, battery pole sheet cutting. |
Electronics and Semiconductors | Precision parts: processing lead frames, micro connectors. Semiconductor molds: cutting wafer carriers, ceramic packaging molds. |
Precision Machinery | Micromachining: manufacturing clock gears, optical instrument parts (such as aperture blades). Sample processing: trial production of metal parts in rapid prototyping development. |
Recently, Shanghai ANTS Machiner Equipment Co., Ltd. received an inquiry from a Lebanese customer who needed a wire cutting machine to process automotive gears. A servo motor is required. Generally, the common drive methods in wire cutting machines are servo motors and stepper motors. They differ in performance, control methods, and costs. Servo motors are mainly used in medium-speed and slow-speed wire cutting is machines with high precision, but the price is relatively high. Reasonable recommendations need to be made based on the customer's workpiece.

Please see the comparison table of fast wire, medium wire and slow wire below:
| Item | Fast wire EDM | Medium Wire EDM | Slow Wire EDM |
Wire Type | Molybdenum wire (reusable) | Molybdenum wire or coated molybdenum wire | Copper wire (one-time use) |
Wire feeding method | Reciprocating wire feeding (pulling back and forth) | Reciprocating wire feeding + multiple cutting | One-way wire |
Surface roughness | Ra 3.2–1.6 μm | Ra 1.6–0.8 μm | Ra 0.6–0.1 μm |
Cutting method | One rough cut, no multiple trimming | Rough Cut + Fine Trim | Multiple cutting (rough cutting + multiple finishing) |
Material utilization | High (molybdenum wire can be reused) | middle | Low (copper wire once) |
Main Application | Rough processing, high volume, low cost parts | Medium precision parts, small molds | High-precision molds, precision parts, precious materials |
- To summarize briefly, fast wire cutting is suitable for low-cost, low-precision rough processing, medium wire cutting takes into account both precision and efficiency, and is suitable for parts and molds with medium precision requirements, while slow wire cutting is suitable for precision molds, complex parts and mirror processing, etc., and has a high cost.
