Compétence Tourner - Rationnel, précis et efficace

Se fondant sur la longue expérience avec les matériaux de coupe extrêmement durs PcBN et PCD des domaines percer, fraiser et aléser, MAPAL a acquis une compréhension profonde des processus pour le tournage également. L’accent est dans ce cadre clairement porté sur le tournage dur.

L’offre de MAPAL inclut des solutions d’outils spéciales pour le tournage exempt de torsion pour  ’usinage complet de surfaces d’étanchéité, de surfaces de stockage et de sièges du palier  ur le tour. Cela économise un serrage complexe des pièces à usiner sur les machines à rectifier.

Pour exploiter de manière optimale les coûteuses plaquettes circulaires PcBN, MAPAL a mis au point un système avec des plaques circulaires indexables qui permet un tournage simple défini de la plaquette dans la machine. Ainsi, la plaquette peut être exploitée de manière optimale.

Le système d’incision flexible VersaCut garantit une stabilité maximale lors du rainurage dur avec PcBN. Il offre des conditions préalables idéales pour les exigences spéciales de l’usinage dur.

​​​​​​​MAPAL offre aujourd’hui une large sélection de plaquettes de coupe réversibles PCD et PcBN pour le tournage dur avec une sélection étendue du matériau de coupe et de la structure des arêtes. 

ハードターニングのための革新

  •  PcBN round inserts with indexing from MAPAL enable optimal use of the cutting material.

    PcBN round inserts with indexing

    Costly cutting material such as PcBN must be utilised to the maximum. At the same time the reliability and stability of the processes must not be impaired. The MAPAL system for hard turning with indexable PcBN round inserts ensures easy handling and optimal cutting material utilisation. 

  • Tools for scroll-free turning from MAPAL.

    Scroll-free turning

    With the scroll-free turning process, which is a special form of kinematics between the rotating workpiece and a rotating tool, grinding is not required. Parts can be fully machined on the lathe. In comparison to conventional machining, this turning method makes it possible to reduce machining times by more than 70 % - with increased process reliability and tool life.

  • Maximum stability during hard turning with PcBN - with VersaCut from MAPAL.

    VersaCut grooving and turning system

    The flexible grooving system VersaCut offers the optimal prerequisites for the special requirements of hard machining. The PcBN-tipped inserts are clamped extremely stably. The system covers inserts of varying widths and shapes for recessing and groove turning, as well as for machining threads.

PcBN and PCD indexable inserts

MAPAL has an extensive programme of PCD- and PcBN-tipped indexable inserts for applications with particularly high requirements. The two extremely hard cutting materials polycrystalline diamond (PCD) and polycrystalline cubic boron nitride (PcBN) are indispensable in today's production world.

PcBN indexable inserts

PcBN cutting materials from MAPAL create the ideal prerequisites for cost-effective machining due to their high hot hardness, wear resistance and edge strength. 
As a result, the machining times and as a consequence the workpiece costs can be reduced significantly with very good part quality at the same time.

Advantages:
  • PcBN grades for continuous cut and interrupted cuts
  • Large selection of standard geometries and chamfer designs available for optimal tool life and quality
  • Multiply tipped designs for greater cost-effectiveness of the tools
  • Indexable inserts with high-accuracy G tolerance

PCD-tipped cutting inserts from MAPAL.

PCD Indexable inserts

Due to its hardness and wear resistance even with extremely abrasive materials, high cutting values and tool lives can be achieved with the PCD cutting material. 
MAPAL started to rely on PCD during the design of high-performance tools at an early stage and has obtained broad know-how and many years of experience. Different machining tasks with varying requirements in relation to abrasiveness, part geometry and machines are realised with PCD. 

​​​​​​​Advantages:
  • Highest cutting data and cost-effectiveness
  • High accuracy of the cutting edge geometries
  • Latest manufacturing methods offer additional possibilities
