Features:

The PCD cutting tools have advantages such as good rigidity, compressive strength, heat conductivity, wear resistance, etc. High precision and efficiency can be got in high speed cutting with them. The surface roughness can be Ra 0.8-0.2 in semi-finish and finish processing of the precise parts. It is stable for the processed surface precision. Otherwise the life of PCD cutting tool is 50-300 times compared to cemented carbide cutters.



The PCBN cutting tools have good heat conductivity whose is 13 times to cemented carbide. CBN is a kind of ideal material to make nonferrous metal cutters as CBN has better heat conductivity and chemical stability than diamond furthermore it is resistant to elevated temperatures 1300-1500and inert to Fe group materials. PCBN cutters have good rigidity because it is higher at 1000 than the rigidity of cemented carbide at room temperature. The good precision and surface quality (Ra 0.2-2.0) make it possible for turning to substitute grinding with little abrasion.



Application:

PCD cutting tools are mainly used for processing aluminum and aluminum alloys (various silicon-aluminum alloys and silumin), copper and copper alloy, Babbitt metal, wood and various kinds of wood based fiber materials, aluminum oxide reinforced floor boards, various kinds of wear-resistant plastic, Bakelite, graphite, stone materials, cemented carbide, hard paper board, etc.



PCBN cutting tools are mainly used for processing various kinds of hardened steel, tool steel, mold steel, bearing steel(HRC 45-70), chilled cast iron, high-chromium cast iron, nickel-base high temperature alloy, cobalt-base high temperature alloy(HRC 35-70), difficultly processing graphite cast iron and various kinds of other difficultly processing nonferrous materials.
