A sharpened tungsten needle is a needle-shaped tool made of tungsten steel, which is often used in various delicate work, such as textile, handicraft, medical and other fields. It consists of a needle body and a needle tip. The needle body is usually made of tungsten steel, which has high hardness and high wear resistance, while the needle tip is sharpened, which can better penetrate and puncture various materials. Sharpened tungsten needles are widely used, such as tungsten-grade argon arc welding, electronic probe components, cathode discharge needles, iodine tungsten lamps, bromine tungsten lamps, automotive H series, halogen tubes, etc.
A sharpened tungsten needle is a needle-shaped tool made of tungsten steel, which is often used in various delicate work, such as textile, handicraft, medical and other fields. It consists of a needle body and a needle tip. The needle body is usually made of tungsten steel, which has high hardness and high wear resistance, while the needle tip is sharpened, which can better penetrate and puncture various materials.
1. Material and manufacturing
The needle body of a sharpened tungsten needle is usually made of tungsten steel, which is an alloy material with high hardness, high wear resistance and corrosion resistance. It is composed of tungsten, carbon, iron and other elements, and is made by high-temperature smelting and precision machining. The hardness of tungsten steel can reach HRC90 or above, making it an ideal material for making sharpened tungsten needles.
The tip of the sharpened tungsten needle needs to be finely ground to make it sharp and sharp. This process requires the use of high-precision grinders and grinding tools to ensure that the accuracy and shape of the needle tip meet the requirements. During the grinding process, different grinding methods and materials can be used, such as diamond grinding wheels, ceramic grinding wheels, etc., to obtain the best grinding effect.
2. Shape and specifications
The shape and specifications of the sharpened tungsten needle can be adjusted according to different application scenarios. Generally speaking, the length of the sharpened tungsten needle can range from a few millimeters to tens of millimeters, while the diameter can range from tens of microns to a few millimeters. The angle and shape of the needle tip can also be adjusted as needed, such as straight tip, curved tip, double tip, etc.
3. Characteristics and applications
The sharpened tungsten needle has the characteristics of high hardness, high wear resistance, corrosion resistance and high temperature performance, which enables it to show excellent performance in various application scenarios. The following are the main characteristics and applications of sharpened tungsten needles:
1. High hardness: The hardness of tungsten steel is very high, which can withstand various high-intensity workloads and is not easy to deform and wear.
2. High wear resistance: Tungsten steel has excellent wear resistance and can maintain sharp shape and size during long-term work.
3. Corrosion resistance: Tungsten steel has strong corrosion resistance to most chemicals and can prevent the impact of chemical corrosion on its performance.
4. High temperature performance: Tungsten steel has good high temperature performance and can maintain its hardness and wear resistance in high temperature environments.
5. Wide range of application fields: Sharpened tungsten needles are widely used in textiles, handicrafts, medical and other fields, such as threading needles in the textile industry, engraving needles for handicrafts, suture needles in the medical field, etc.
IV. Use and maintenance
When using sharpened tungsten needles, pay attention to the following points:
1. Before use, check whether the needle body and needle tip are defective or damaged, and replace or repair them if necessary.
2. Avoid collision with hard objects or impact by external forces during use to avoid damage or deformation.
3. After use, it should be cleaned in time and properly stored to prevent contamination and damage.
4. If it is found to be worn or deformed, it should be replaced or repaired in time to ensure its performance and use effect.
In short, the sharpened tungsten needle is a needle-shaped tool made of tungsten steel. It has the characteristics of high hardness, high wear resistance, corrosion resistance and high temperature performance. It is widely used in various fine work fields. When using it, you should pay attention to check its status and maintain it to ensure its performance and use effect.
