Super-hard cutting tool playing a big role in high speed mac
Superhard cutting tools appears because of higher requirements on the workpiece materials hardness, mainly include diamond tools and cbn tools.
Diamond tools have high hardness and abrasive resistanct, and can be used for machining Copper,Aluminum and other ferrous metal,some alloy, ceramic and some carbide insert, fibers and composites.
Diamond tools can be divided into natural diamond and man-made diamond. Natural diamond are formed with natural environment. However, man-made diamond are produced with high temperature and high pressure, are mainly used for army industry, aerospace,chemical industry,ect.
Diamond Tools Series include Graphite, Single Crystal, Powder, PCD and PCD Tools. In current times, 50% of single crystal diamond tools are used for producing saw blades. And depending on the application field, PCD Tools can be used for different industries, such as Oil exploration, mining, cutting tools, wire drawing blank. And the PCD saw balde are used for stone and struction field. PCD Drill Tools are mainly used for mining industry and oil exploration field. PCD Cutting Tools are used for high precision machining field.
CBN is simialr with diamond tools, also is synthesized in high temperature and high pressure environment. It has high hardness, good thermal conductivity and small Coefficient of expansion. Besides, CBN Inserts also have stalbe chemcial and thermal stability, and not affect with same element, which is better than diamond tools.
Compared with diamond, cbn perform more stable, is more suitable for machining hardened steel, thermal spraying materials, chilled cast iron and other Co-based and Ni-based materials above HRC35.
In some developed countries, cbn inserts already widely used for automotive, and other high hardness materials industry. CBN inserts are more suitable for dry cutting and high speed machining, which can be used for machining gray cast iron with cutting speed above 2000m/min. For high hardness materials machining industry, Halnn already make the whole solutions, such as machining different materials rolls, heavy turning, interrupt turning, hard turning hardened steel ,turning instead of grinding, ect. And Halnn also offer customized service, such as chipbreaker insert, wiper insert, ect.
If you have any problems on machining high hardness materials, no mattter used cbn or pcd tools, you can contact with us, we will help you make the whole solutions.
