  • PCD Inserts

    Diamond tools have the characteristics of high hardness, high compressive strength, good thermal conductivity and wear resistance, etc.The above characteristics of diamond tools are determined by the crystal state of diamond.In diamond crystals, four valence electrons of carbon atoms are bonded according to tetrahedral structure, and each carbon atom forms covalent bonds with four adjacent atoms, thus forming the structure of diamond. This structure has strong binding force and orientation, thus making the diamond extremely hard.Because the structure of polycrystalline diamond (PCD) is a sintered fine-grain diamond with different orientation, its hardness and wear resistance are still lower than that of single-crystal diamond, although the mixture is added.However, because PCD sintered body is isotropic, it is not easy to crack along a single cleavage surface. Main indicators: 1.The hardness of PCD can reach 8000HV, which is 8 ~ 12 times of the hard alloy; 2.The thermal conductivity of PCD is 700W/mK, which is 1.5 ~ 9 times of cemented carbide, even higher than PCBN and copper, so PCD tool heat transfer quickly; 3.The friction coefficient of PCD is generally only 0.1 ~ 0.3 (the friction coefficient of carbide is 0.4 ~ 1), so PCD tool can significantly reduce the cutting force; 4.The thermal expansion coefficient of PCD is only 0.9×10^-6 ~ 1.18×10^-6, only equivalent to 1/5 of the cemented carbide, so PCD tool thermal deformation is small, high processing accuracy; 5.PCD tools and non-ferrous and non-metallic materials between the affinity is very small, in the process of processing chip is not easy to stick on the tip of the knife to form a chip tumor. Beijing Demina manufacturing BT-150H can grind PCD inserts with good finish through constant pressure grinding and flexible feed.

  • PCD Tool Manufacturing Process

    About PCD tool manufacturing The use of the PCD tool to process aluminum workpieces has the advantages of long tool life and high metal removal rate. Its disadvantages are that the tool is expensive and the processing cost is high. This point has reached a consensus in the machinery manufacturing industry. However, in recent years, many changes have occurred in the development and application of the PCD tool. Today, the performance of aluminum materials is not what it used to. When processing various newly developed aluminum alloy materials (especially high-silicon-content composite materials). In order to optimize productivity and processing quality, the PCD tool grade and geometric parameters must select carefully to suit Different processing requirements. Another change of PCD tool is that the processing cost has been continuously reduced and the market competition pressure has improved the manufacturing process of tools. The price of the PCD tool has dropped by more than 50%. Use correctly of PCD tool Prerequisites for the correct application of the PCD tool to obtain satisfactory processing results. Although the specific reasons for tool failure vary, they are usually caused by incorrect use of the object or method. When ordering the PCD tool, the user should correctly grasp the tool adaptation range. For example, when using a PCD tool to process ferrous metal workpieces (such as stainless steel). Because diamond easily reacts with steel carbon elements, it will cause PCD tools to wear quickly. Therefore, the correct choice of PCBN tool for machining hardened steel. Generally, in order to reduce the cutting force and prevent the build-up edge, the PCD tool should use a positive cutting angle. However, when processing high-silicon aluminum alloys (especially when PCD tool is used instead of hard alloy tools), the back angle of the PCD tool should slightly smaller than that of the original carbide tool (such as 250) to improve the cutting of PCD tool. Cutting performance on high silicon aluminum alloy. The positive rake angle of a PCD tool should not too large, because of the larger the tool rake angle, the lower the cutting edge strength. In other words, the smaller the PCD tool rake angle, the higher the cutting edge strength.
