Reasons for Inaccurate Dimensions in Electrical Discharge Machining (EDM) Machines
The size of the spark position in an electrical discharge machining (EDM) machine is mainly influenced by factors such as discharge parameters, the conductivity of the electrode and workpiece, the type of electrolyte, viscosity, fluidity, and so on. Therefore, even if the electrode is made precisely, there can still be a few micrometers of error in the spark position.

Common Issues and Troubleshooting Methods for Electric Discharge Machining (EDM) Machines Controlled by Stepper Motors
How to choose the power supply for the drive of an electrical discharge machining (EDM) machine tool. First, determine the supply voltage for the drive, and then determine the operating current. The power supply current is generally based on the output phase current I of the drive. If a linear power supply is used, the power supply current can generally be taken as 1.1 to 1.3 times I; if a switching power supply is used, the power supply current can generally be taken as 1.5 to 2.0 times I.

What are the precautions to take when installing a micro-hole processing machine?
The technology for machining micro-holes requires the cooperation of machining equipment. The quality of the machine tool, the correct installation method, and the proper operating procedures are all closely related. In this article, I will share with you the important considerations to keep in mind when installing a micro-hole machining machine.

The application range of micro-hole processing machine tools includes: 1. Electronics industry: used for drilling micro-holes in circuit boards and electronic components. 2. Aerospace: for manufacturing precision parts with micro-holes for fuel injection and cooling systems. 3. Medical devices: used in the production of components like syringes and catheters that require micro-holes for fluid flow. 4. Automotive: for creating fuel injectors and other components that require precise micro-holes. 5. Optical devices: used in the production of lenses and filters that require micro-holes for light transmission. 6. Textile industry: for creating micro-perforations in fabrics for various applications.
Micro-hole processing machines are now widely used in the processing fields of filter equipment, synthetic fiber spinnerets, computer printer heads, printed circuit boards, television screen barriers, planetarium star plates, and medical devices such as red blood cell filters.
To better use the electrical discharge machining (EDM) machine, attention should be paid to the maintenance of these four aspects.
The electrical discharge machining (EDM) machine uses a continuously moving fine metal wire (called the electrode wire) as the electrode to perform pulsed spark discharge to erode metal and cut into shape. The electrical pulse electrode is a hollow copper rod. The medium passes through the hole in the copper rod and discharges with the workpiece, corroding the metal to achieve perforation. It is used for processing ultra-hard steel, hard alloys, copper, aluminum, and any conductive materials into fine holes.
