Grinding the tip of micron-level tungsten needles requires the use of precision grinding equipment and processes to ensure that the shape and size of the tungsten needle meets the requirements. The following will introduce several commonly used micron-level tungsten needle tip grinding equipment.
1.Grinder
The grinder is one of the commonly used equipment for grinding the tip of micron-level tungsten needles. It has the characteristics of high rotation speed, small vibration and high precision, and is suitable for micron-level processing of various materials. The grinding wheel of the grinder can be selected according to the needs of different grit sizes, materials and hardness to obtain the best grinding effect. During the grinding process, attention needs to be paid to controlling the rotation speed and pressure of the grinding wheel, as well as the grinding time, to avoid excessive stress on the tungsten needle, which may cause cracks or deformation.
2. CNC machine tools
CNC machine tools are high-precision, high-efficiency processing equipment suitable for micron-level processing of various complex shapes and structures. On CNC machine tools, you can control the motion trajectory and processing parameters of the machine tool by writing programs to achieve automated and precise processing. The processing accuracy of CNC machine tools can reach micron or even nanometer levels, so it is suitable for grinding high-precision tungsten needles. During the grinding process, attention needs to be paid to controlling parameters such as the machine tool’s rotational speed, feed speed, and cutting depth to ensure grinding quality and efficiency.
3. Ultrasonic cleaning machine
Ultrasonic cleaning machine is a device that uses the combination of ultrasonic vibration and cleaning liquid to clean the surface of materials. In an ultrasonic cleaning machine, ultrasonic vibrations can produce tiny bubbles. When these bubbles burst on the surface of the material, they will generate high-pressure shock waves, thereby cleaning away dirt, grease and other impurities on the surface. Ultrasonic cleaning machine is suitable for surface cleaning and deburring of tungsten needles, and can effectively improve the surface quality and accuracy of tungsten needles.
4. Optical grinder
The optical grinder is a high-precision, high-finish processing equipment suitable for surface processing and precision grinding of various materials. The grinding head of the optical grinder is made of high-hardness, high-wear-resistant materials such as optical glass or optical crystal, which can achieve extremely high surface finish and precision. On an optical grinder, precision grinding and polishing of tungsten needles can be achieved by controlling parameters such as the rotational speed, feed speed, and cutting depth of the grinding head.
In short, grinding the tip of micron-level tungsten needles requires the use of precision grinding equipment and processes. Appropriate equipment and technology should be selected according to different needs, and processing parameters and quality inspection should be strictly controlled to ensure that the produced tungsten needles meet the requirements. At the same time, attention should be paid to production safety issues, such as wearing protective clothing and regularly checking the safety status of equipment. Only in this way can high-quality micron-level tungsten needle products be produced to meet the needs of different fields.
