Main Factors to Consider When Buying a Wire Cutting EDM Machine
When purchasing a wire cutting EDM machine, it's essential to focus on several key aspects to ensure a sound investment:
-
Precision and Accuracy: Ensure the machine can produce precise cuts within tight tolerances, and verify its cutting speed, accuracy, and repeatability.
-
Software and Programming: Advanced software and programming capabilities can significantly enhance productivity and help meet tight deadlines.
-
Condition: Examine the machine's age, maintenance history, and potential wear and tear on critical parts to ensure longevity and performance.
Additional Options to Consider
Here are some features and options you might encounter:
- Automatic Wire Threading: Reduces setup time and increases efficiency by automatically threading the wire through the workpiece.
- Automatic Wire Tensioning: Maintains consistent wire tension during cutting for more accurate cuts and reduced wire breakage.
- Chiller: Cools the dielectric fluid, improving cutting performance and reducing the risk of thermal distortion.
- Workpiece Height Measurement: Ensures more precise cutting and reduces the risk of machine damage.
- Rotary Indexing Table: Allows the workpiece to be rotated for more complex cuts and reduced setup time.
- Tool Changers: Automatically change the electrode during cutting for more complex cuts and reduced manual intervention.
- Remote Monitoring: Enables operators to monitor performance and receive notifications of issues or errors.
Control and Software
Wire cutting EDM machines rely on specialized software and controls for programming and cutting:
- CAM (Computer-Aided Manufacturing) Software: Programs machine movements and generates the necessary G-code for cutting. Features may include 3D modeling, simulation, and optimization.
- CNC (Computer Numerical Control) Software: Controls machine movements and positions the wire for precise cutting. Features may include automatic toolpath generation, machine monitoring, and real-time error detection.
- EDM Power Supply: Generates the electrical discharge used for cutting. Control may be via software or manual adjustments.
- User Interface: Allows operators to interact with the machine and input commands or adjust settings, often through touchscreens, keyboards, or other devices.
Difference Between Wire Cutting EDM and Die Sinking EDM Machines
Wire cutting and die sinking EDM machines serve different purposes:
- Wire Cutting EDM: Uses a thin wire electrode to cut through a workpiece, ideal for creating complex shapes such as gears without extensive tooling.
- Die Sinking EDM: Uses a shaped electrode to create cavities or impressions in the workpiece, ideal for creating molds and dies.

How Wire Cutting EDM Works
Wire cutting EDM, also known as wire erosion, is a non-traditional machining process using an electrically charged wire to cut and shape metal parts. The wire, typically made of brass or tungsten, generates an electrical discharge that vaporizes the metal, creating precise cuts. This process is ideal for producing intricate shapes with high accuracy.
Budget Considerations
Prices for used wire cutting EDM machines range from €13,000 to €48,000, depending on various factors. The cost of transportation, installation, and necessary repairs or maintenance can also impact the overall investment. Kitmondo's pricing algorithm Valorexo can help determine a fair market price.
Logistic Considerations
- Transport: Consider logistics for transporting the machine.
- Software Version and Language: Ensure compatibility with your needs and access to technical support.
- Installation: Requires specialized equipment and expertise.
- Training: Necessary for proper operation.
- Maintenance: Ensure access to spare parts and technical support.
