Turning competence - Rational, exact and efficient

Building on extensive experience with the extremely hard cutting materials PcBN and PCD from the area of boring, milling and reaming, MAPAL has also obtained a profound understanding of the turning process. A clear focus is on hard turning.

The range from MAPAL includes special tool solutions for scroll-free turning for complete machining of sealing faces, bearing surfaces and bearing seats on the lathe. This saves time-consuming re-clamping of the workpieces on grinding machines.
To utilise optimally costly PcBN round inserts, MAPAL has developed a system with indexable round inserts that makes simply defined rotation of the insert in the machine possible. In this way the insert can be utilised optimally.
Maximum stability during hard grooving with PcBN is ensured by the grooving system VersaCut. It offers the optimal prerequisites for the special requirements of hard machining.

Today MAPAL offers a broad selection of PCD and PcBN-tipped indexable inserts for hard turning with an extensive selection of cutting materials and cutting edge design. 
In addition, the MAPAL portfolio includes a broad HSK-T program with turning holders for the connections HSK-T40, 63 and 100. A complete machine-specific range of conversion systems makes it possible to integrate the advantages of the HSK-T connection also in an existing environment.

Product highlights

  •  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

HSK-T - the standardized hollow taper shank for turning

To be able to utilise the advantages of the HSK connection also for usage on lathes or turning-milling centres, the HSK-T standard (T = Turning) was developed. Compared to other HSK variants the driving element play on the HSK-T is limited and in this way the effect on the position of the insert minimised.
HSK-T can be used as a universal connection for rotating and stationary tools and makes possible minimum set-up and tool changing times. The changing times for tools reduce to less than 30 seconds with the HSK connection. Ten to 15 minutes are normal here with other standardised systems.

MAPAL offers a complete turning holder programme in the sizes HSK-T 40, 63 and 100. In this way almost all turning methods are covered. The tools can be operated with HSK-A tool changers, which ensures a very high degree of flexibility.

    Tools with HSK-T connection

    MAPAL offers a complete turning holder programme in the sizes HSK-T 40, HSK-T 63 and HSK-T 100. In this way almost all turning methods are covered. 
    The tools can be operated with HSK-A tool changers. This aspect ensures a high degree of flexibility.

  • Conversion systems and adapters to HSK-T from MAPAL.

    Conversion systems and adapters to HSK-T

    HSK-T conversion systems make it possible to integrate the advantages of the HSK-T connection in an existing environment. The process can be specifically optimised using the conversion systems to HSK-T, as due to the high accuracy when changing the tools, times for setting up or breaking-in are practically not required.
