Cemented carbide refers to a kind of alloy material made by the powder metallurgy process of the hard compound of the more refractory metal and the bond metal. One or more of the carbon compounds and the bond metal alloy are usually Known as cemented carbide, manufacturers of precision parts and components are inseparable from cemented carbide;

     Cutting price is a common way of cutting hard alloy bars, sheets and wires. For grooving or cutting under 1mm, ultra-thin diamond slices are commonly used for processing. Diamond resin matrix slices, in which the outer ring belt is resin The middle part of the bond abrasive working layer is made of high-strength and high-rigidity metal material, which is often used in medium- or large-scale deep-cut grooving and cutting;

     In the process of turning cemented carbide parts, the hardness of the tool itself must be higher than the hardness of the processed parts. Therefore, the current tool materials for turning cemented carbide parts are mainly made of high-hardness, high-heat-resistant non-metallic adhesive PCD and PCD. Mainly CBN;

1. For cemented carbide parts with hardness less than HRA90, choose BNK30 material CBN tool for large margin cutting, and the tool will not be brittle or burn; for cemented carbide parts with hardness greater than HRA90, generally choose CDW025 material PCD tool or Adopt resin bond diamond grinding wheel for grinding;

    2. When performing precision machining of grooves above R3 on cemented carbide, for those with a relatively large machining allowance, generally use BNK30 material CBN tools for rough machining, and then use a grinding wheel for grinding. The machining allowance is relatively small. , Experience directly use grinding wheel for grinding, or use PCD tool for profiling processing;

    3. The diamond milling cutter made of CDW025 material is used when the crescent groove of the cemented carbide roll is processed, which is also called flying cutter or rotary milling cutter in the industry;

For the milling process of cemented carbide parts, according to the needs of users, we can provide CVD diamond coated milling cutters and diamond insert milling cutters for precision machining, which can replace electrolytic corrosion and EDM processes, and improve manufacturing efficiency and processing. The quality of the product, if the CVD diamond-coated milling cutter is used for micro-milling of cemented carbide, the surface roughness can reach 0.073um;

    The above is the whole content of the processing technology of cemented carbide parts,
