Static Eliminator Discharge Tungsten Needle Cathode Discharge Needle Tungsten Electrode
1. Information Of Tungsten Needle Cathode Discharge Needle:
Tungsten needle is a kind of tungsten product made of pure tungsten or tungsten alloy electrode material, which is ground into a point by one end.Discharge tungsten needle, also known as discharge machining needle, is a special tungsten needle used in electric discharge machining (EDM). It is a tungsten product made of metal tungsten powder as the main raw material. , Tapered design, can easily enter the narrow processing space, and can achieve high-precision processing results.
2. Specification Of Tungsten Needle Cathode Discharge Needle:
| Grinding range | 0.5~6mm |
| Sharpening angle | 10°——90° |
| Color | Metallic silver gray |
| Surface | Polished |
| Shape of Tungsten Needle | straight, pointed, round, flattened |
| Application | Used for tungsten-level argon arc welding, electronic probe components, cathode discharge needles, iodine tungsten lamps, bromine tungsten lamps, automotive H series, halogen tubes, static eliminator etc. |
3. Features Of Tungsten Needle Cathode Discharge Needle:
| Features of Tungsten discharge needle | High melting point, high hardness, high strength, good electrical conductivity, high temperature resistance, corrosion resistance, ablation resistance and not easy to deform, etc. |
4. Production Process Of Tungsten Needle Cathode Discharge Needle:
The production steps of discharge tungsten needles include material selection, processing, heat treatment, grinding and spraying, that is, high-purity tungsten rods are used as raw materials first, and then the tungsten rods are made into tungsten needle blanks of specified size and shape through precise cutting and processing technology , and then process the tungsten needle blank by turning, milling, drilling, grinding and other processes, put it into a high-temperature furnace for heat treatment after processing, and finally grind and spray the heat-treated tungsten needle. It should be noted that because the production of discharge tungsten needles is more difficult, the manufacturing cost is also higher than that of ordinary tungsten needles.
5. Application Of Tungsten Needle Cathode Discharge Needle:
Used for tungsten-level argon arc welding, electronic probe components, cathode discharge needles, iodine tungsten lamps, bromine tungsten lamps, automotive H series, halogen tubes, etc.
Aerospace, machinery manufacturing, electronics, automotive, medical and other industries. In the field of aerospace, it is usually used to make components such as engine nozzles and combustion chambers; in the field of electronics, it is mainly used to make electronic components such as capacitors and resistors. In addition, discharge tungsten needles are often used to manufacture tiny metal parts and high-precision molds to meet the processing needs of various industrial fields.
