EDM drilling machines are a commonly used metal processing equipment, which forms tiny holes in metal workpieces by means of electric spark discharge. This processing method has many advantages, one of which is high processing efficiency. This article will discuss the topic of the high processing efficiency of EDM drilling machines.

First of all, EDM drilling machines have the characteristics of high-speed processing. Compared with traditional drilling methods, EDM drilling machines can complete a large number of hole processing in a short time. This is because it uses electric spark discharge, through the arc discharge between the discharge electrode and the workpiece, the surface of the workpiece produces physical effects such as high temperature and high pressure, thereby forming tiny holes. This processing method does not require a rotating drill bit, so it can achieve high-speed processing and improve processing efficiency.

EDM drilling machines also have high processing adaptability. Since EDM drilling machines use electric spark discharge for processing, their processing process is not limited by the hardness and brittleness of the workpiece material. Whether it is hard or brittle materials, they can be processed by EDM drilling machines. This processing adaptability can meet the processing needs of different materials and improve processing efficiency.

However, the processing efficiency of EDM drilling machines is affected by many factors. Among them, the hardness of the workpiece material is an important factor. Generally speaking, EDM drilling machines are suitable for processing metal materials with higher hardness, such as steel, copper alloy, etc. For these materials, efficient processing can be achieved because the electric spark discharge can quickly melt the metal and form holes. However, for materials with lower hardness, such as aluminum alloy, plastic, etc., the processing efficiency of EDM drilling machines will be reduced, because the melting point of these materials is low, and the energy of the electric spark discharge cannot quickly melt the material.

Secondly, the processing efficiency of EDM drilling machines is also affected by the size and shape of the workpiece. Generally speaking, EDM drilling machines are suitable for processing workpieces with small apertures and deep holes. This is because the electrode diameter of EDM drilling machines is small, which can achieve higher processing accuracy. However, for workpieces with large apertures and shallow holes, the processing efficiency will be reduced because multiple discharges are required to complete the formation of the hole.

In addition, the processing efficiency of EDM drilling machines is also affected by the electrode material and electrode shape. The electrodes of EDM drilling machines are usually made of copper or copper alloys because copper has good electrical conductivity and thermal conductivity. However, copper has a low melting point and is easily affected by the heat of electric spark discharge, resulting in faster electrode wear. In order to improve the service life and processing efficiency of the electrode, wear-resistant materials such as molybdenum-copper alloy can be used to make the electrode. In addition, the shape of the electrode will also affect the processing efficiency. Generally speaking, the shape of the electrode should match the shape of the workpiece to achieve the best processing effect.

In addition, the processing efficiency of EDM drilling machines is also affected by the discharge parameters. The discharge parameters include discharge current, discharge time, discharge interval, etc. Reasonable selection of discharge parameters can improve the processing efficiency. Generally speaking, higher discharge current and shorter discharge time can increase the processing speed, but at the same time, it will also increase electrode wear and workpiece surface roughness. Therefore, it is necessary to adjust according to the specific situation to achieve the best processing effect.

In general, EDM drilling machines have certain processing efficiency advantages, especially suitable for processing workpieces with higher hardness, smaller aperture and deep holes, however, for workpieces with lower hardness, larger aperture, and shallow holes, the processing efficiency will be reduced. In addition, the processing efficiency of EDM drilling machines is also affected by many factors such as workpiece material, size and shape, electrode material and shape, and discharge parameters. Therefore, in practical applications, it is necessary to select and adjust according to the specific situation to achieve the best processing effect.
