What is the function of the conductivity of the tungsten discharge needle

As the core tool of EDM technology, the conductivity of the discharge tungsten needle is the key factor that determines its performance. Tungsten, as a transition metal, exhibits excellent conductive properties, enabling the discharge tungsten needle to efficiently transfer current and generate stable spark discharge during EDM. This unique performance not only significantly improves processing efficiency, but also ensures superior processing accuracy and surface quality.

During the EDM process, the discharge tungsten needle is used as an electrode to erode the workpiece using the instantaneous high temperature and high pressure generated by the EDM discharge. Its conductive properties directly affect the stability and efficiency of spark discharge. The highly conductive discharge tungsten needle can ensure the stable transmission of current during the machining process, thereby generating uniform and continuous spark discharge. This stability is the basis for efficient machining and ensures the accuracy and consistency of the workpiece during the machining process.

The conductivity of the discharge tungsten needle also plays an important role in improving the processing quality. In EDM, the electrical conductivity determines the energy density and distribution of the spark discharge. The highly conductive discharge tungsten needle can generate sparks with higher energy density, thus achieving fine processing of the workpiece material. This not only improves the finish and precision of the machined surface, but also reduces the heat-affected zone and recast layer during machining, thereby improving the overall machining quality.

Discharge tungsten needles have a wide range of applications in industrial manufacturing and technological innovation. In the aerospace field, it is widely used in the manufacture of key components such as engine nozzles and combustion chambers, which have extremely high requirements on the conductivity and high temperature resistance of the material. With its excellent conductivity and high melting point, the discharge tungsten needle ensures the stability and reliability of these key components in extreme environments.

In the electronics industry, discharge tungsten needles are mainly used to manufacture electronic components such as capacitors and resistors. These components have strict requirements on the conductivity and processing accuracy of materials. The high conductivity and high-precision processing capability of the discharge tungsten needle have significantly improved the performance and stability of electronic components.

The conductivity of the discharge tungsten needle also plays an important role in other fields. In the medical field, discharge tungsten needles are used to manufacture medical devices such as scalpels and electrodes. Their high conductivity and good biocompatibility enable medical devices to transmit current more accurately during surgery, thereby improving the efficiency and Security. In the field of mechanical manufacturing, discharge tungsten needles are widely used to manufacture high-precision molds and parts. With their excellent conductivity and processing capabilities, they ensure the excellent performance of molds and parts in dimensional accuracy and surface quality.
