Competenza in alesatura e barenatura di precisione

Gli utensili per la lavorazione di precisione di fori rappresentano la competenza principale di MAPAL. La storia di grande successo, che ancora oggi MAPAL continua a scrivere nella lavorazione fine di forature, ha avuto inizio nell'anno 1954 con il primo "prototipo" di alesatore. Grazie all'esperienza decennale, al costante sviluppo e all'ottimizzazione delle soluzioni utensili, MAPAL è oggi in grado di offrire, oltre a soluzioni speciali su misura, anche un vasto assortimento standard di utensili per alesatura e barenatura.

    Fino a diametro 315 mm per qualsiasi materiale

    Unitamente al diametro e alla tolleranza di foratura richiesta, il materiale è uno dei criteri di selezione principali per la scelta dell'alesatore più adatto. L'assortimento MAPAL comprende, oltre ai canonici utensili per la lavorazione di acciaio, acciaio inox, ghisa e alluminio, anche soluzioni specifiche per l'alesatura sicura e conveniente di titanio, superleghe, plastiche e materiali compositi.

    Rivestimenti ad alte prestazioni

    Per garantire la lunga durata dell'utensile e risultati di lavorazione ottimali, il rivestimento dei taglienti è un fattore decisivo. MAPAL offre una vasta scelta di substrati e di rivestimenti, specifici per i vari compiti di lavorazione, sempre all'avanguardia grazie anche all'impianto di applicazione del rivestimento proprio dell'azienda.

    Reconditioning in original quality

    Re-ground reaming tools and cutting inserts that achieve a machining performance of up to 100 percent compared to new tools represent an important control lever for production costs.
    For this reason MAPAL offers tool reconditioning in the form of re-grinding and re-coating in manufacturing quality. 
    And that includes comprehensive services: If required, MAPAL organises the collection and delivery of the tools and guarantees standardised original quality worldwide.

  • State-of-the-art manufacturing facilities form the basis of the high manufacturing precision at MAPAL.

    Latest production equipment

    3D design and simulations form the basis for the manufacture of MAPAL tools. The data are transferred via interfaces to the related machining centre that forms part of the state-of-art range of machinery available on site. In this way MAPAL reaming tools are produced to the highest quality requirements with monitoring and control by experienced staff. 
    Precision and effectiveness are guaranteed.

    Custom solutions

    Special machining tasks require special tools. For this reason MAPAL offers custom reaming tools individually tailored to the requirements of the customer. 
    Requirements are met optimally with special lead geometry and coatings as well as multi-stepped tools. 
    Combination solutions with other tool technologies from MAPAL can further increase the productivity and reduce non-productive times.

Tools with guide pads

Highest accuracies with the MAPAL principle

Tools with guide pads have high accuracy and performance due to 
  • the direct guiding in the bore using guide pads and 
  • the high quality of the precision-ground indexable inserts.
Particularly on the fine machining of bores, the requirements are exceptionally high on the cutting material, coating, cutting edge geometry and the quality of the grinding. Due to highly sensitive and accurate adjusting systems, the required diameter is produced to the μm from the first part. 
​​​​​​​The setting effort is significantly reduced by the EasyAdjust-System from MAPAL, as it is only necessary to set the diameter of the tools.

High-performance reamers with cylindrical shank

Replaceable head reamers

MAPAL replaceable head reamers for exact concentricity and changing accuracies and simple handling.

MAPAL offers replaceable head reamers with different head systems. They impress with exact radial run-out and changeover accuracy, and with safe and simple handling, particularly during assembly and dismantling. 
​​​​​​​
The standard programme covers versions for through bores and blind bores as well as a broad choice of cutting materials.

Reaming solutions for large diameters

Solutions for reaming large diameters from MAPAL.

Especially for machining from a diameter of 40 mm, a programme of high-performance reamers with individual configuration options and HSK or module shank is available. 
​​​​​​​
From the simple cutting ring to high-performance tools with straightforward insert change on site – for every application MAPAL offers a suitable solution for the high-accuracy and cost-effective machining of almost all workpiece materials.

Floating Holders

MAPAL has an extensive portfolio of floating holders for reaming operations on lathes.

For reaming operations on lathes

During fine bore machining, the alignment of the pilot bore with the tool axis is a prerequisite for the correct function of the reamer. On the usage of reamers on lathes it is often necessary to compensate for axial errors between the tool adapter and the bore to be machined. This error can be corrected either by aligning the tool on the machine or using a floating holder. A floating holder is particularly useful if the offset changes continuously due to the thermal expansion of the machine or at different positions when rotating the revolver.
MAPAL floating holders guarantee optimal results during machining at high speeds and feeds.
