Recently, Shanghai ANTISHICNC received an inquiry from an Argentine company. The customer needed to process hexagonal or plum head screws. The customer initially wanted to use an electric discharge drilling machine to process the hexagon socket on the nut. After receiving the customer’s processing requirements, the Shanghai ANTISHICNC technical team gave professional advice and recommended the G45 fully CNC EDM machine to the customer.
Customer workpiece processing photo information:
The EDM drilling machines can only punch round holes and cannot process hexagon sockets. It is recommended to use electric spark EDM machine for making hexagonal or plum head screws. Full CNC is recommended for large batches. If the quantity is small, single-axis CNC electric spark EDM machine is recommended. It also depends on the customer’s workpiece material. If it is tungsten steel, full CNC electric spark EDM machine is recommended, which has high processing efficiency and low electrode loss.
The drawings of related workpieces that can be processed by CNC electric spark EDM machine are as follows:
The specific differences between electric spark EDM machine and EDM drilling machines are as follows:
| Specifications | Electric Spark EDM Machine | EDM drilling machine |
| Definition | Electric Spark EDM Machine: refers to the method of machining a workpiece by the electric erosion effect of pulse discharge between the tool electrode and the workpiece electrode in a certain medium, commonly known as discharge machining. It includes various processing forms such as electric spark perforation, electric spark forming, and electric spark wire cutting. | EDM drilling machine: It is a special type of EDM equipment used for drilling holes. It is mainly used to process small holes on various conductive materials, such as cutting initial holes, nozzle holes, filter holes, air holes, etc. for superhard conductive materials. |
| Processing function | EDM Machine: In addition to drilling, it can also process a variety of complex shapes. For example, EDM forming can process various cavity molds, such as injection molds, die-casting molds, etc.; EDM wire cutting can cut various two-dimensional parts, such as punches, concave molds, etc. | Discharge drilling machine: The main function is to drill holes. It can process small holes of different diameters. The smallest hole can be 0.015mm. It can also process small holes with tapers. It is widely used in the fields of precision mold processing. It is generally used as a supporting equipment for EDM wire cutting machines to process wire holes, etc. |
| Electrode characteristics | Electric spark EDM machine: The shape of the electrode depends on the processing requirements. In the electric spark forming process, the electrode is usually a formed electrode made of copper or graphite, and its shape corresponds to the shape of the cavity to be processed; in the electric spark wire cutting process, the electrode is a smaller diameter electrode wire, such as molybdenum wire, brass wire, etc. | Discharge drilling machine: The electrode is generally a thin metal copper tube that moves vertically up and down continuously, called an electrode wire. The medium passes through the thin hole in the middle of the copper rod hole to play a role in cooling and chip removal. |
| Processing speed | Electric Spark EDM Machine: is relatively slow, especially SDM, because it requires gradual removal of metal material through pulsed discharge to form complex shapes. | Discharge drilling machine: It is a machine with high drilling efficiency in EDM, and can process small holes on workpieces quickly. This is because its discharge energy is concentrated on the drilling part, and the movement of the electrode and the circulation system of the working fluid are optimized for drilling. |
