CarmexThe optimal tools for your industryDiamond Too sMetricCarmex Diamond ToolsCarmex PCD,CVD-T and PCBN cutting tools are designed for highproductivity and longer tool life when machining materials ranging fromplastics to brass,cast iron,hardened steel,and super alloys.The insertsprovide faster machining times compared to grinding and outperformceramics,thereby reducing production costs.2PCDPCD is a composition of diamond particles sintered together with a metallic binder.The polycrystallinestructure creates a hard and wear-resistant tool with high thermal conductivity to quickly transfer heataway from the cutting edge.Since diamond is the hardest material available,it provides the highestabrasive resistance.PCD tools are used for non-ferrous materials,high-silicon aluminum,carbon fiber,and plastic (CFRP).CVDThe CVD cutting material is harder than PCD and twice as wear-resistant.CVD delivers variousbenefits when machining long-chipping aluminum and magnesium alloys,high-silicon aluminum,precious metal alloys,plastics with abrasive fillers,tungsten carbide,and ceramic green compacts.Laser equipment is used to cut out the segments from the CVD-thick film.These are then attachedto inserts by brazing under vacuum.The chip breakers and cutting edges are also laser formed.Theadvanced chip breaker reduces contact of the chip with the insert surface,which considerably reducesheat generation and energy consumption.In addition,the controlled chip breaker increases processreliability and reduces cutting forces.PCBNIts high heat resistance combined with the high level of hardness,which is second only to diamond,makes PCBN the ideal cutting material for machining hardened steels.In addition to the machining ofhardened steels(45-72 HRC),this cutting material group is also highly suited to the machining of castmaterials and special alloys-applications in which carbide and cutting ceramic tools often reach theirlimits.CBN material provides excellent heat resistance and can be used at very high cutting speeds.Italso enhances toughness and thermal shock resistance.3
