Description of PCD materials:
99.9% of the components of the PCD are carbon isotopes C12, and their thermal conductivity is 50% better than natural diamond and 2 times faster than copper. Its physical properties are also the best at present.Diamond is the hardest material. A special high-temperature and high-pressure process can be used to attach a tight polycrystalline diamond layer on a cemented carbide substrate.With a diamond cutting tool, you get faster cutting speeds and longer tool life, with higher surface quality and machining accuracy of the material being machined.
Applications Of PCD Cutting Tools:
Automotive industry: processing of aluminum alloy products
Aerospace: titanium aluminum alloy, carbon fiber
Medical industry: pump body and other aluminum alloy materials
Advantages of PCD cutting tools compared with carbide cutting tools:
Higher metal removal rate, faster cycle time, one shift can process more workpieces
Reduce waste, improve quality, stricter size control, perfect surface finish
Optimize machine tool efficiency, Improve production efficiency, Improve equipment utilization
The Table Below Provides A Comparison Between PCD cutting tools and carbide tools
| PCD Cutting Tools | Carbide Cutting Tools | advantages of PCD cutting tools | |
| Thermal Conductivity | 700W/mK | 78~467W/mK | PCD tool heat transfer quickly |
| Coefficient Of Friction | 0.1~0.3 | 0.4~1 | PCD Can significantly reduce cutting forces |
| Hardness | 8000HV | 667~1000HV | PCD Tool thermal deformation is small, high precision machining |
| Thermal Expansion Coefficient | 0.9×10^-6~1.18×10^-6 | 4.5×10^-6~5.9×10^-6 | |
| Cutting wear resistance | 20-40 Times Than Carbide Cutting Tools | ||
| The affinity between PCD cutting tools and non-ferrous metals and non-metallic materials is very small. Chips do not easily stick on the tip of the cutting edge during processing to form a built-up edge | |||
