EDM machine  is a common metal processing equipment, which is widely used in automobile manufacturing, aerospace, mold manufacturing, and other fields. According to different classification standards, EDM machines can be divided into many different types. This article will introduce several common classifications of EDM machines.

Classification by working principle

1. Traditional EDM machine: The traditional EDM machine adopts the pulse discharge method for processing, and generates sparks through the discharge of high-frequency voltage, which causes tiny melting and evaporation on the surface of the workpiece, thereby realizing metal cutting and processing. The traditional EDM machine has the advantages of high processing precision and fast processing speed and is suitable for processing metals with high hardness.

2. Wire-cut EDM machine: Wire-cut EDM machine is a processing equipment that uses wire to cut workpieces. It uses metal wire as the electrode and generates sparks through the discharge of high-frequency voltage so that an electric spark discharge is generated between the metal wire and the workpiece, so as to realize the cutting of the workpiece. Wire-cutting EDM machine has the advantages of high processing precision and fast cutting speed and is suitable for cutting thin sheet metal.

3. Drilling EDM machine: Drilling EDM machine is a kind of equipment specially used for drilling. It adopts the way of electric spark discharge and generates sparks through the discharge of high-frequency voltage so that electric spark discharge is generated between the electrode and the workpiece, so as to realize the drilling of the workpiece. Drilling EDM machine has the advantages of high processing precision and fast drilling speed, and is suitable for drilling metals with high hardness.

Classification by processing objects

1. Metal EDM machine: Metal EDM machine is mainly used to process metal materials. It can cut, drill, and thread various metal materials, and is widely used in mold manufacturing, automobile manufacturing, aerospace, and other fields.

2. Non-metal EDM machine: Non-metal EDM machine is mainly used to process non-metal materials. It can cut, engrave and punch holes in ceramics, glass, stone, and other materials, and is widely used in handicraft production, architectural decoration, and other fields.

Classification by control method

1. Manually controlled EDM machine: Manually controlled EDM machine is a device that controls the processing process by manual operation. Operators need to control according to processing requirements, including adjusting processing parameters, selecting processing paths, etc.

2. CNC EDM machine: CNC EDM machine is a device that realizes the processing process through computer control. The operator only needs to input the processing parameters and processing path on the computer, and the EDM machine can automatically process, which greatly improves processing efficiency and precision.

To sum up, different types of EDM machines play an important role in the field of metal processing. They each have unique characteristics and application fields, providing more choices and possibilities for the industry. With the continuous advancement of technology, we believe that more innovative EDM machines will appear in the future, bringing more breakthroughs and advancements in metal processing.
