What are the key points in the difficulty and method of processing tungsten alloy bars?

Tungsten Alloy is a very tough and wear-resistant material widely used in fields such as aerospace, shipbuilding, mechanical processing, and chemical engineering. Due to the high hardness and high melting point of Tungsten Alloys, processing is relatively difficult. The editor of tungsten alloy manufacturers will introduce the key points and methods of processing tungsten alloy bars below.

1. Molybdenum alloy cutting tools: Molybdenum hard alloy (hard rhenium alloy) is a material composed of tungsten carbide (WC) particles and cobalt (Co) matrix, with extremely high hardness, wear resistance, and thermal stability. The use of molybdenum alloy cutting tools can better resist the wear and high-temperature thermal effects of tungsten alloys.

2. Reduce cutting speed: The high hardness of tungsten alloys requires greater cutting force during cutting, so it is necessary to reduce cutting speed to reduce cutting force and reduce tool wear. The machining quality and tool life of tungsten alloy bars can be improved by reducing the cutting speed.

3. Reasonable cutting parameters: When processing tungsten alloy bars, it is necessary to determine reasonable cutting parameters based on factors such as specific material hardness, cutting tool material and shape, and cutting objectives, such as cutting speed, forward speed, feed speed, and cutting depth.

4. Cooling lubricant: Due to the high melting point and low thermal conductivity of tungsten alloy, it is easy to generate high temperatures. Therefore, it is necessary to use cooling lubricant to reduce the temperature of the cutting part, reduce thermal deformation, softening, and tool wear. Commonly used cooling lubricants include water-soluble cutting fluid and cutting oil.

5. Special fixing device: Tungsten alloy bars usually have high strength and hardness, making fixing and clamping stroke a key issue in the machining process. Special fixing devices can be used to ensure the stability and accuracy of the bar, such as fixtures, vertical machining centers, and fitter tools.

6. Full grinding before processing: Before processing tungsten alloy bars, it is necessary to thoroughly grind and polish the bars to ensure their surface quality and accuracy. Grinding can be done using diamond grinding wheels or tungsten alloy grinding wheels, and suitable grinding fluids can be used for cold grinding.Tungsten Alloy Rods For Counterweight

7. Control of processing temperature: When processing tungsten alloy bars, it is necessary to control the processing temperature to avoid excessive temperature causing material softening, deformation, and wear of cutting tools. Effective cooling systems and appropriate cutting parameters can be used to control the machining temperature.

8. Avoid vibration of tungsten alloy bars: Due to the high hardness and brittleness of tungsten alloy, it is easy to cause vibration and resonance, resulting in increased surface roughness and damage to cutting tools. Damping devices and reasonable cutting trajectories can be used to reduce vibration and resonance.

9. Control tool wear: The high hardness of tungsten alloy can easily lead to rapid tool wear, so regular inspection and replacement of tools are necessary to ensure processing quality and efficiency. The wear of cutting tools can be judged by indicators such as chip morphology, surface quality, and cutting force.

10. Heat treatment after machining: Tungsten alloys may experience internal stress and structural changes due to the effects of high temperature and cutting stress during the machining process. Therefore, heat treatment is required to eliminate stress and restore the microstructure. The commonly used heat treatment methods include annealing, solid solution, and aging.

In summary, the processing difficulty of Tungsten Alloy Rod manufacturers is mainly reflected in their high hardness, high melting point, and wear resistance. In order to overcome these difficulties, it is necessary to choose appropriate cutting tools, reasonable cutting parameters, cooling lubricants, and processing devices, control the processing temperature and tool wear, and perform appropriate heat treatment after processing. Only by comprehensively considering these key points can the processing quality and efficiency of tungsten alloy bars be effectively improved.
