When buying a wire erosion EDM machine, it is important to consider several key factors to ensure you make the right investment for your business. Here are the main points to look at:
Precision and Accuracy: One of the most crucial factors to consider is the machine's precision and accuracy. The machine should be capable of producing precise cuts within a tight tolerance range. You should verify the machine's cutting speed, accuracy, and repeatability, as well as its overall performance.
Software and Programming: Another important factor to consider is the machine's software and programming capabilities. A machine with advanced software and programming features can significantly improve your productivity and help you meet tight deadlines.
Condition: It is crucial to examine the machine's overall condition, including the machine's age, maintenance history, and any potential wear and tear on critical parts. Proper maintenance and care are crucial to the longevity and performance of a wire cutting EDM machine.
Here are some of the main options you might encounter:
Automatic wire threading: This feature allows the machine to automatically thread the wire through the workpiece, reducing setup time and increasing efficiency.
Automatic wire tensioning: This feature maintains a consistent wire tension during cutting, resulting in more accurate cuts and reducing wire breakage.
Chiller: A chiller may be used to cool the dielectric fluid, improving cutting performance and reducing the risk of thermal distortion.
Workpiece height measurement: This feature measures the height of the workpiece, allowing for more precise cutting and reducing the risk of damage to the machine.
Rotary indexing table: This accessory allows for the workpiece to be rotated, allowing for more complex cuts and reducing setup time.
Tool changers: A tool changer may be used to automatically change the electrode during cutting, allowing for more complex cuts and reducing the need for manual intervention.
Remote monitoring: Some machines may offer remote monitoring capabilities, allowing operators to monitor the machine's performance and receive notifications of any issues or errors.
These EDM machines rely on specialized software and controls to program the machine's movements and control the cutting process. Some of the most common types of software and controls used include:
CAM (Computer-Aided Manufacturing) software: This type of software is used to program the machine's movements and generate the G-code necessary to control the cutting process. CAM software may offer features like 3D modeling, simulation, and optimization to improve the efficiency and accuracy of the cutting process.
CNC (Computer Numerical Control) software: CNC software is responsible for controlling the machine's movements and positioning the wire or electrode for precise cutting. CNC software may offer features like automatic toolpath generation, machine monitoring, and real-time error detection to optimize the cutting process.
EDM power supply: The EDM power supply is responsible for generating the electrical discharge used to cut the workpiece. The power supply may be controlled through software or via manual adjustments, depending on the specific machine and its features.
User interface: The user interface allows the operator to interact with the machine and input commands or adjust settings. The user interface may be a touchscreen, keyboard, or other input device, and may offer features like machine monitoring, error reporting, and job scheduling.
Wire cutting and die sinking EDMs are two different types of electrical discharge machining processes used in the metalworking industry.
Wire cutting EDM machines ("wire EDM" or "wire erosion machines") use a thin wire electrode to cut through a workpiece. The wire is made of a conductive material, such as brass or tungsten, and is usually around 0.1 to 0.3 mm in diameter guided by a series of pulleys and moves through the workpiece under the control of a computer program. This process is ideal for creating complex shapes, such as gears, without the need for extensive tooling.
Die sinking EDM machines ("sinker EDM" or "spark erosion machines") use a special electrode, usually made of graphite or copper, to create a cavity or impression in the workpiece. The electrode is lowered into the workpiece and a high-frequency electrical discharge is used to remove material from the surface of the workpiece. This process is ideal for creating molds and dies used in the manufacturing of metal parts.

Wire cutting erosion, also known as wire EDM (Electrical Discharge Machining), is a non-traditional machining process that uses an electrically charged wire to cut and shape metal parts.
The wire is typically made of brass or tungsten, and is connected to a power source. When the wire is brought close to the workpiece, an electrical discharge is generated between the wire and the workpiece, creating a spark that vaporizes the metal and creates a small crater.
The spark is then extinguished, and the wire moves a small distance away from the workpiece. This process is repeated thousands of times per second, creating a series of craters that eventually cut through the workpiece. The wire is constantly fed through the workpiece, creating a kerf or slot in the metal.
Wire cutting EDM machines are capable of producing very precise and complex shapes, and can be used on a variety of materials, including metals such as steel, aluminum, and copper, as well as some non-metallic materials. The process is ideal for creating parts that have intricate shapes or require very tight tolerances, as the wire can cut very fine details and produce very accurate dimensions.
Wire cutting EDM machines are widely used in industries such as aerospace, medical, and automotive, where precision and complexity are critical to the final product.
The price of wire cutting EDM machines can vary significantly depending on several factors, such as the machine's brand, age, condition, capabilities, and optional features. However, as a general guideline, the prices for used wire cutting EDM machines on the market can range from around €20,000 to €200,000, or more, depending on the machine's specifications.
Lower-priced machines may be older or have fewer capabilities, while higher-priced machines may be newer, have more advanced features, or be from well-known brands. However, buyers should keep in mind that the price of a machine is not the only consideration, and they should also factor in the machine's overall quality, reliability, and performance to ensure that it meets their production needs.
It is also worth noting that the cost of transportation, installation, and any necessary repairs or maintenance can also impact the overall cost of a wire cutting EDM machine.
The price range for used wire cutting EDM machines is between 13 000€ and 48 000€. You can always use our pricing Algorithm Valorexo to pinpoint a fair market price.
Transport: Transporting a wire cutting EDM machine can be challenging due to its size and weight. Buyers should consider the logistics of transporting the machine from the seller's location to their own facility. This may involve hiring a specialized transport company that has experience in moving heavy machinery.
Software version and langue: Wire cutting EDM machines rely on specialized software to control the cutting process and program the machine's movements. Buyers should ensure that the machine they are purchasing is equipped with the correct software version for their needs and that they have access to technical support and training for the software.
Additionally, the language of the software may also be a consideration, particularly for buyers who operate in multilingual environments. Some wire cutting EDM machines may offer software that supports multiple languages, while others may be limited to a specific language. Buyers should verify that the machine's software is compatible with the languages spoken in their facility, or consider purchasing language packs or additional software if necessary.
Installation: Once the machine has been transported to the buyer's facility, it will need to be installed and set up. This may require specialized equipment and expertise, such as a crane or rigging equipment. Buyers should also ensure that their facility has the necessary infrastructure, such as electrical and ventilation systems, to support the machine.
Training: Operating a wire cutting EDM machine requires specialized knowledge and training. Buyers should ensure that they have the necessary expertise in-house or can arrange for training from the manufacturer or a qualified third-party provider.
Maintenance: Regular maintenance is essential to keep a wire cutting EDM machine running smoothly and prevent downtime. Buyers should ensure that they have the necessary resources and expertise to maintain the machine, including access to spare parts and technical support.
