Perfectly yours. Super hard cutting materials Efficient, economical, effective

This catalogue combines the experiences gained in the turning area into a standard programme. Carefully selected cutting materials in conjunction with special cutting edge designs and MAPAL quality guarantee the user a high degree of economy. And this means PCD and PcBN should also become a staple of your production system.

Super hard cutting materials | introduction MAPAL Competence: Super hard cutting materials The two super hard cutting materials polycrystalline diamond (PCD) and polycrystalline cubic boron nitride (PcBN) have become a staple of the modern production world. In machining non-ferrous materials, PCD allows for a considerable increase in productivity and quality. When machining hardened steel, PcBN dramatically simplies the production processes. Additionally, the cutting speeds and tool life when machining cast iron and sintered iron materials can be decisively increased with PcBN. The MAPAL...

Efficient, economical and effective MAPAL PcBN indexable inserts Today modern, stable machine tools with fast, efcient drive systems and high levels of accuracy represent the backbone of an economical production system. In order to fully utilise the production potential using high cutting speeds and feeds for the cutting edge, the use of modern cutting materials with a high degree of hardness, such as PcBN, is an appropriate solution. MAPAL PcBN cutting materials, with their high heat resistance, wear resistance and strong edges, provide the ideal conditions. As a result machining times and...

Super hard cutting materials | PcBN and PCD indexable inserts PCD – with extreme hardness and high performance MAPAL PKD – inserts When using modern design materials, whether in the manufacture of vehicles, in the aerospace industry and also increasingly in machine manufacturing, a priority is improved use of energy. With the same or even higher dynamics, energy consumption needs to be reduced. For this reason the proportion of non ferrous metals, bre reinforced plastics (CRP, GRP) and sandwich materials is steadily rising. Using PCD to cut these materials is ideal. Because of its high...
