Die sinking Electrical Discharge Machining (EDM) machines are highly specialized tools capable of crafting intricate 3D shapes with unprecedented precision. These machines employ an advanced technique where thousands of sparks are discharged between an electrode and the workpiece, eroding the material in a meticulously controlled manner. Die sinking EDM machines are renowned for their ability to deliver intricate components across industries such as automotive, aerospace, and medical technology.

When purchasing a used Die sinking EDM machine, one must consider a few critical factors. Firstly, machine capacity, power, and CNC controls are crucial for ensuring the machine can fulfill your specific production needs. Additionally, it's essential to consider the machine's compatibility with the types of electrodes needed for your projects, as well as its axis travel capability for accommodating the required component size.

The age and condition of the machine significantly affect its performance and longevity. Therefore, prior maintenance records and servicing history should be thoroughly reviewed. Lastly, the availability of spare parts and after-sales service is another key aspect.

Looking to level up your operations with the pinnacle of machining technology? We present to you the die sinking EDM (Electrical Discharge Machining) machines, available on Exapro. This type of advanced machinery is designed for both large-scale manufacturers and smaller enterprises aiming for precision, quality, and efficiency.

Die sinking EDM machines, also known as cavity type EDM or volume EDM, deliver unparalleled precision in the creation of complex 3D shapes. These machines utilize the technique of electrical discharge machining where thousands of sparks are discharged between an electrode and the workpiece, eroding the material in a very controlled way.

When investing in a die sinking EDM machine, there are several main technical parameters you should consider:

Machine Capacity: This refers to the maximum workpiece dimensions the machine can accommodate. This will be critical to your decision, as it should match the scale of the components you plan on producing.

Power: The power of an EDM machine directly influences the speed of machining. Machines with higher power ratings typically allow for faster production times.

Electrode Size and Type: The size and type of electrode used can greatly affect the accuracy and detail of the final product. Make sure the machine is compatible with the types of electrodes required for your projects.

CNC Controls: CNC controls are an important aspect as they manage the automated functioning of the EDM machine. Look for machines that offer easy-to-use yet sophisticated control systems, ensuring the efficiency and accuracy of your machining operations.

Axis Travel: This refers to the distance the machine’s components can move in the X, Y, and Z directions. A larger axis travel allows for the creation of larger components or working on multiple smaller components at once.

Servicing and Maintenance: Check the availability of servicing and spare parts. Some machines may require specific maintenance or parts that can be hard to find.

Machine Age and Condition: Last but not least, the machine's age and current condition can affect its price, durability, and maintenance needs.

Main manufacturers GF Machining Solutions (formerly Agie Charmilles): This Swiss company has a strong reputation for high-quality and high-precision machinery. Their FORM series, particularly the FORM P 350, is a popular choice for die sinking EDM, known for high performance and precision.

Mitsubishi: This Japanese manufacturer is well-known in the EDM industry. The EA series, especially the EA12V model, stands out for its advanced controls and high precision.

Sodick: Another renowned Japanese manufacturer, Sodick’s AG series is popular for die sinking EDM. The AG60L model is often praised for its user-friendly interface and excellent performance.

ONA: ONA, based in Spain, is the largest European manufacturer specialized in EDM. The ONA AV series, specifically the AV35 model, is highly valued for its efficiency and durability.

Makino: Also from Japan, Makino is famous for its robust and reliable machines. The EDAF series, particularly the EDAF2 model, offers high precision machining with an intuitive control interface.

Exeron: This German company focuses on high-quality EDM and HSC machines. Their Exeron HSC series, notably the HSC300 model, is known for its robust construction and excellent precision.

Difference between die sinking and wire EDM machines Die sinking EDM and wire EDM machines use electrical discharge machining technology, but they function in slightly different ways and are used for different applications.

Die Sinking EDM Machines: Die sinking EDM, also known as cavity type EDM or ram EDM, involves an electrode of the desired shape being used to erode material from the workpiece. The electrode and workpiece do not make physical contact but are separated by a small gap. An electrical discharge (spark) jumps this gap, causing material from the workpiece to melt and vaporize.

The electrode usually is made of graphite or copper. The process is primarily used for creating complex cavities and indentations in hardened steel molds and dies, or any conductive material. It's often used in mold-making industries, as well as for creating prototypes and small batches of parts.

Wire EDM Machines: Wire EDM machines, on the other hand, use a thin wire as the electrode. This wire, usually made of brass, copper, or a tungsten alloy, is continuously fed from a spool through the workpiece, and the electrical discharge occurs along the wire's path.

Wire EDM is primarily used to cut intricate contours or cavities in pre-hardened steel without the need for heat treatment to soften and re-harden them. It's also excellent for making punches, tools, and dies from hardened steel. It can also be used to create tiny holes and intricate patterns.

In summary, the main difference between die sinking EDM and wire EDM lies in the electrode type and movement. Die sinking EDM uses a shaped electrode to create complex 3D shapes, while wire EDM uses a thin wire to cut 2D shapes through the full thickness of the workpiece. The choice between the two depends on the specific requirements of the task at hand.

Cost and budget The cost of a new die sinking EDM machine can vary widely based on several factors such as the machine's size, capabilities, manufacturer, and the included features. The price for a new machine could range from around 50 000€ for smaller, less complex models to well over 200 000€ for larger, high-end models with advanced features.

This is just a general range and prices may have changed since then. It's also important to consider that additional costs such as installation, training, maintenance, and necessary peripheral equipment (like EDM wire, filters, and replacement parts) could also add to your total investment.

For a used machine, it ranges from 9000€ and 32000€ for standard models.
