overview

PCD (Polycrystalline Diamond) is a synthetic diamond product that is produced by sintering together selected diamond particles with a metal matrix, using sophisticated technology. The diamond and matrix, when sintered together under high temperatures and pressures, creates a PCD tool blank that is high in uniform hardness and is abrasive resistant in all directions. PCD Inserts is made of PCD tips( cutting from PCD blank) and a carbide substrate.
In ultra-precision machining, the two basic precision of single crystal diamond tool are the precision of blade profile and the blunt circle radius of cutting edge. It is required that the roundness of the cutting edge of the circular cutting tool for machining aspheric lens should be less than 0.05μm, and the straightness of the cutting edge for machining the polyhedral mirror should be 0.02μm. The blunt radius (ρ value) of the cutting edge of the tool indicates the sharpness of the cutting edge of the tool. In order to adapt to various machining requirements, the radius of the cutting edge of the blade ranges from 20nm to 1μm.

Because there are some residual bonded metals and graphite among diamond particles, the bonded metals in the coalescence state or veined distribution will reduce the wear resistance and life of the tool. In addition, there are residual solvent metals, which are in direct contact with the diamond surface.

· Product features
·PCBN has strong chemical properties and will not react with ferrous metals at high temperature.
· The red hardness of CBN can reach 1370°C, almost twice that of diamond: at 800°C, the hardness of CBN is higher than that of hard alloy, ceramics and PCD at room temperature. Therefore, the cutting speed of CBN cutting tool can be higher than carbide, ceramic tool 2-5 times, with extremely high cutting efficiency.
· The wear resistance of CBN is 5-10 times that of coated hard alloy and 3-5 times that of ceramics, with extremely high life.

1. Application range of diamond tools
(1) Processing of non-ferrous materials that are difficult to process
Processing copper, zinc, aluminum and other non-ferrous metals and their alloys, the material is easy to adhere to the tool, processing difficulties. Using the characteristics of low friction coefficient of diamond and low affinity with non-ferrous metals, diamond cutting tools can effectively prevent the bonding between metal and cutting tools. In addition, due to the large elastic modulus of diamond, the cutting edge deformation is small, the non-ferrous metal cutting extrusion deformation is small, the cutting process can be completed in small deformation, so as to improve the quality of the machining surface.
(2) Processing of non-metallic materials that are difficult to process
When processing difficult non-metallic materials containing a large number of high hardness particles, such as glass fiber reinforced plastics, silicon filled materials, hard carbon fiber/epoxy resin composite materials, the hard point of the material makes the tool wear seriously, hard alloy tool is difficult to process, and diamond tool has high hardness and good wear resistance, so the processing efficiency is high.
(3) ultra-precision machining
With the advent of modern integrated technology, machining is developing towards high precision, which puts forward a rather high requirement for tool performance. Because diamond friction coefficient is small, low thermal expansion coefficient, high thermal conductivity, can cut extremely thin chips, chips easy to flow out, small affinity with other substances, not easy to produce debris tumor, small heat, high thermal conductivity, can avoid the impact of heat on the blade and the workpiece, so the blade is not easy to passivation, cutting deformation is small, can obtain high quality surface.
