Tungsten carbide is one of the most common materials used in CNC cutting tools. It is a very hard and versatile material that is used to make a variety of cutting tools, including router bits, milling cutters, drills, reamers, and taps. Tungsten carbide is often used for high-precision and high-speed operations, as it is extremely resistant to wear and tear. It is also very resistant to high temperatures and can withstand high cutting speeds. Additionally, tungsten carbide has excellent cutting properties, allowing for high accuracy and repeatability.

Manufacturing Process

• Raw material configuration:Select the configuration ratio according to the alloy grade, and add additives such as Ti, Ta, Ta, CrC, Ru, etc.
• ball milling:Ball milling of various raw materials to achieve the required particle size.
• spray drying:The raw materials after ball milling are dried to obtain pressed grades.
• Testing for fluidity and looseness:Detect the fluidity and looseness of the powder after drying.
• Pressing:Use a mold to press the raw material into shape.
• sintering:Sintering in a vacuum sintering furnace.
• Blank inspection:Test the physical properties of the sintered blank, such as density, magnetic saturation, coercive force, metallographic structure, hardness, etc.
• Grinding all over: The grinding machine grinds the tool thickness, front angle, back angle, R angle, etc. to the tolerance range.
• Passivation: In order to increase the cutting edge strength, the cutting edge of the insert is passivated using a drilling and milling machine.
• Finished product testing:Check whether the appearance, shape, dimensions, etc. of the finely ground blade meet the requirements.
• coating:PVD/CVD coating of tools upon request.
