Our factory can supply variety Diamond Drill ( PCD Drill). Diamond PCD layer 2-4mm, Total Thickness is 8mm-15mm, Diameter is 1mm-14mm.
Exnt Wear resistance, Higher impact resistance, Toughness, Thermal Stability low friction coefficient, low heat expansion coefficient, good strength and toughness. It can realize high speed cutting, hard material cutting and high precision processing. The PCD blank meets the requirement of environmental protection.
Suitable for Laser cutting and EDM. Normal shape is round, Max Diameter is 46mm, can be cut into triangles, rectangles, square, sectors or as request PCD layer thickness is 0.4mm -0.60mm Available in overall thickness as followings: 0.5mm,0.6mm 0.8mm,1.0mm,1.2mm, 1.6mm, 2.0mm, 3.2mm, 4.76mm, 5.0mm, 10.0mm,15.0mm Available Grain size: 0.5-1μ m, 5μ m, 10μ m, 25μ m, 30μ m, 2-30μ m Features 1. The hardness of PCD reaches 8000HV, which is 80 to 120 times that of tungsten carbide. 2. The thermal conductivity of PCD is 1.5 to 9 times that of tungsten carbide, and it is even higher than that of PCBN and copper. Its thermal conductivity is 700W/mK. The PCD blank can transfer heat fast. 3. The friction coefficient of PCD is only 0.1 to 0.3, while that of tungsten carbide is 0.4 to 1. The PCD cutting tool features small cutting force. 4. The heat expansion coefficient of PCD is 0.9× 10-6 to 1.18× 10-6, which is only one fifth that of tungsten carbide. The PCD cutting tool features small thermal deformation and high processing precision. 5. The affinity between the PCD cutting tool and the materials, The cuttings will not attach to the tool during processing. Application:
