The tools in an overview
Polycrystalline Diamond PCD
PCD is a synthetically manufactured substrate of diamond particles embedded in a metallic binder phase. It is produced by high-pressure, high-temperature synthesis or by high-pressure liquid phase sintering. The hard wear-resistant PCD cutting edges with around 90 percent diamond and grit sizes between 0.8 and 15 µm, have a very long tool life when machining non-ferrous materials. The high cutting edge sharpness is achieved by grinding, spark erosion or precision lasers. The metallic binder phase generates a certain toughness, which is advantageous in a number of applications. The main areas of application are aluminum alloys with more than 4 percent silicon, carbide green-compacts, titanium alloys, and GFRP and CFRP composites.
Chemical Vapor Deposition (CVD) Diamond
Synthetic CVD diamond is formed by chemically coating a carrier substance in a gas zone. CVD diamond is 99.9 percent nearly pure diamond. As a cutting material, it is brazed onto carrier tools in layers between 0.2 and 1.2 mm. In the case of CVD diamond, which consists of diamond crystals strung together in the form of rods, the impact of the cutting edge takes place directly in the direction of the greatest hardness. Therefore, CVD diamond as a cutting material is harder than PCD and natural diamond. In addition, like natural diamond and MCD, CVD diamond has the highest thermal conductivity of all cutting materials and, with a precision-lasered cutting edge, a high cutting edge sharpness similar to MCD. The sharp cutting edges offer particular advantages when machining CFRP and GFRP composites, carbide green compacts, ready-sintered carbide, ceramics and wrought aluminum alloys with high tool life.
Monocrystalline Diamond MCD
Monocrystalline diamond consists of pure carbon similar to a natural diamond and is synthesized in a high pressure process with 60,000 bar pressure and temperatures of over 1,500°C. Cutting edges, cut with the highest precision, are used for high-gloss cutting of non-ferrous metals such as gold, silver, brass, copper, but also plastics and aluminum alloys below 4 percent silicon. The MCD is also used in high-gloss steel machining by means of ultrasonic support. It is the only cutting material that enables high-gloss machining with a geometrically defined cutting edge. Its advantages are combined from its high hardness, jointless structure, high thermal conductivity and low adhesion tendency.
Cubic boron nitride CBN
Cubic boron nitride is characterized by the combination of physical, mechanical and chemical properties. Especially, its high thermal resistance and hardness allow economical machining of hardened steel with a geometrically determined cutting edge. CBN substrates are used as cutting material compound systems. By varying the volume fraction, grain size and binder system, different properties can be set, which can be advantageously applied to the respective application. Through the interaction of CBN substrate, geometric design of the cutting edge, adapted cutting values and stable tool system, metal removal rates, accuracies and high surface quality can be achieved that are superior to grinding technology. Only in rare cases are special machines required for this purpose.
TiroTool offers high hardness precision tools for all areas of machining.
