News from the reaming and fine boring sector

MN reamers with short delivery times, new cutting materials for special requirements

MAPAL presents two brand new cutting materials: HP016 and HP018. They are specially designed for the requirements involved in reaming high-alloyed and stainless steels, cast steel and hardened steel. Cutting material HP016 is suitable for all machining operations involving a slightly interrupted cut, while cutting material HP018 is used for a continuous cut. Both are based on a silicon-doped PVD coating on two different varieties of carbides with low cobalt content, making them extremely resistant to wear and offering great dimensional accuracy.

The PVD coating has a fine crystalline microstructure, combining high levels of hardness and ductility. The cutting materials are thermally very stable and offer impressive high-temperature stability and coating adhesion. To create an optimum surface in through bores and blind bores, the PVD coating is deposited in the µm range. This ensures the cutting edges retain their sharpness.

The new cutting materials are used for market launch in the reamers in the MN series by MAPAL, among others. These tools represent the utmost accuracy and are now also ideally suitable for use in hard reaming applications as well as reaming stainless steel thanks to the new cutting materials. They operate according to the MAPAL principle – with one insert and a guide pad opposite. Depending on the application, the guide pads are made from carbide, cermet or PCD.

Um die Lieferzeiten bei der Einschneiden-Reibahlen deutlich zu verkürzen, hat MAPAL das Portfolio bereinigt und konzentriert sich nun auf acht Baureihen der MN-Reibahlen. Dank Optimierungen in Konstruktion, Fertigung und Logistik ist das Unternehmen in der Lage, die kundenspezifisch gefertigten Reibahlen in Hartmetall- und Cermet-Ausführung innerhalb von zehn Arbeitstagen zu liefern. Das ist in der Branche bisher einzigartig. Neben den beiden neuen Schneidstoffen sind zahlreiche weitere Schneidstoffe und Beschichtungen für alle gängigen Werkstoffe verfügbar. Die Schneiden sind mit allen Standardanschnitten, AS, DZ, EK und SZ, ab Lager lieferbar.
