What Materials Can be Processed by CNC Single Axis EDM Machine?
Graphite
The most preferred choice for electrodes due to its high strength, temperature, and wear resistance. Offers a cleaning action at low speeds and is cost-effective.
Brass
An alloy of copper and zinc, used for EDM machine and small tubular electrodes. Easier to machine than copper or tungsten but offers less wear resistance.
Tellurium Copper
Suitable for EDM applications needing a fine finish. It has similar machinability to brass and is better than pure copper.
Steel Alloys
Hardened steels and other steel types are suitable for die sinking discharge process due to their toughness, strength, durability, and resilience.
Copper
Highly conductive, copper is an excellent choice for EDM machine. However, its quick heating requires the process to be slower and more controlled, particularly when working on components with thin walls.
Aluminum
Commonly alloyed with other metals to enhance its properties. Its resistance to oxidation and corrosion makes it well-suited for die sinking.
Titanium
With an exceptional strength-to-weight ratio and corrosion resistance, titanium is often used in medical implants.
Tungsten Carbide
Known for its high hardness and melting point, tungsten carbide is challenging to machine conventionally. The die sinking is effective for this material, using copper electrodes with negative polarity for low surface roughness. The process, however, is slower due to the metal’s nature.
Nickel Alloys
Alloys like Inconel, Hastelloy, and Monel, have great heat, corrosion, and oxidation resistance. These properties make them ideal for use in high-temperature applications.
1. Inappropriate parameter adjustment
Incorrect use of electrical parameters is also a reason for unstable discharge. The electrical standard mainly consists of three major electrical parameters: current, pulse width, and pulse gap. If we use too much current, too much pulse width, and too little pulse gap during the machining process, it is the main reason for the unstable discharge phenomenon caused by unreasonable electrical parameter adjustment. The three should be specifically set and selected based on the stability during processing and the requirements of processing technology indicators. If unstable discharge is encountered during processing, the first consideration should be to increase the pulse gap, which can ensure deionization during processing, improve chip removal conditions, and have little impact on process indicators. Another consideration is to reduce the pulse width. Excessive pulse width will cause too many discharge times in a short period of time during processing, making it difficult to deionization and prone to arc burning.
2. Other parameter selection needs to be noted
For example, parameters such as knife lifting speed, discharge time, and knife lifting height. In the case of unstable discharge, the tool lifting speed should be accelerated, the discharge time should be reduced, and the tool lifting height should be increased. When dealing with electrical parameters, special attention should be paid to the difference in discharge stability between rough machining and precision machining. In rough machining, due to the large discharge, large spark gap, and good chip removal effect, stable machining can often be achieved, while in precision machining, the opposite is true, which is prone to unstable discharge. Therefore, special monitoring should be carried out for precision machining of EDM machines. The polarity of the machining should be correct. If the negative polarity (electrode is negative) is mistakenly used in normal machining, unstable discharge may occur, making it impossible to continue machining. The machining polarity should be changed.
How to Choose CNC Single Axis EDM Machine
Material
Identify the types of materials you will be machining, such as hardened steel, aluminum, copper, or exotic alloys. Different machines and electrode materials may be more suitable for specific materials, so ensure the EDM machine can handle the conductivity and hardness of your workpieces.
Efficiency
Depending on your production needs, consider the machine's cutting speed and overall efficiency. If you require high-speed production, select a machine with higher discharge energy and optimized for faster material removal rates while still maintaining acceptable surface finish quality.
Size and Capacity
The machine’s table size, work envelope, and maximum workpiece weight capacity should match the size and weight of the parts you intend to machine. Make sure the CNC single-axis EDM machine can accommodate your largest workpieces comfortably without compromising performance.
Electrode Wear Management
Since electrode wear affects accuracy and surface finish, choose a machine with efficient wear management features, such as automatic wear compensation, or consider the electrode material that best suits your specific needs.
Cost
Consider the total cost of ownership, including the initial investment, operating costs, and potential return on investment. While it’s important to stay within budget, it’s also crucial to choose a machine that offers long-term value, reliability, and the ability to meet your production goals efficiently.

Solutions To Machining Problems Of CNC Single Axis EDM Machine
Low processing efficiency of the EDM machine
The initial electrical discharge machining efficiency is low the electrode size scaling (spark gap) must be large, and the automatic programming can select the condition number of a larger current. The cavity should be pre milled as much as possible. The last few segments of the program have low discharging efficiency-use the fixed time discharging function to effectively control the time of finish machining (the discharging time needs to be preset). Optimize the parameters of CNC Single Axis EDM Machine the pulse interval, increase the servo reference.
Big electrode wear
Improper use of discharging parameters the processing parameters with the priority of low wear should be used. Small electrodes can be selected for micro-machining application types. The discharging power is too big. For small and sharp electrodes, big current machining cannot be used. The discharging power is too small, and the machining efficiency is low, which cause that the discharging time is too long and wear of the electrode. If the electrode wear is too big and the machining speed is too slow, please adjust the parameters to increase the machining efficiency. The electrode material is not good-use high-purity copper or copper-tungsten alloy with lower wear as the electrode material. The pulse width is too small-increase the pulse width to decrease the electrode wear.
Clean the dirt on the CNC single axis EDM machine tool and guide rails every day to keep the EDM machine clean, and turn off the air source and power supply when off work. The EDM machine should be thoroughly cleaned every week, the horizontal and vertical guide rails, the transmission gear racks should be cleaned, and the lubricating oil should be filled.
If you leave the CNC single axis EDM machine for a long time, turn off the power to prevent non-professional operation. Check whether the horizontal and vertical rail wipers work normally, if not, replace them in time. If there is an automatic height adjustment device, check whether it is sensitive and whether to replace the probe. Pay attention to observe whether there is lubricating oil on the surface of the EDM machines horizontal and longitudinal guide rails and racks to keep them well lubricated.
