REAMING | FINE BORING | Introduction REAMING AND FINE BORING COMPETENCE MAPAL offers innovative, cost-effective solutions for machining almost all materials. Today, MAPAL is continuing to write the success story related to the fine machining of bores that started with the "first reamer" in 1954. Thanks to decades of experiences as well as continuous further development and optimisation of the tool solutions, along with tailor-made custom solutions, today MAPAL offers a broad standard programme of tools for reaming and fine boring. Reaming and fine boring are the most common methods for fine...

REAMING | FINE BORING | Introduction Latest production equipment The latest 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...

REAMING | FINE BORING | Introduction HIGHLIGHTS EasyAdjust system Reduced setting effort with the same precision ► more from page 54 MAPAL offers an innovative solution for the simple, precise settings of tools in a very short time with the EasyAdjust system. The EasyAdjust System consists of a precision cassette in which the back taper on the minor cutting edge is already integrated. The setting effort for the back taper is completely eliminated. Due to the exact guidance of the cassette on a precision guide pin, the back taper remains unchanged even during diameter adjustments. The secure...

REAMING | FINE BORING | Introduction CVD cutting material series Optimally matched to reaming The cutting material types were developed especially for reaming. Although the CVD coatings known to date are wear-resistant thanks to the extremely hard elements in the coating, they are at the same time very brittle and susceptible to fracture. The special process control in the production of the new CVD coating, however, makes the coating far more ductile than in the past while retaining its good wear resistance. The CVD grades are therefore very well suited to reaming ductile cast iron...

REAMING | FINE BORING | Introduction TOOL PROPERTIES -- Highest accuracies due to exact setting to the µ MAPAL guide pad technology is unrivalled when it comes to the fine machining of bores in any material. The precision of the bore diameter, circularity and cylindrical form as well as the surface finish cannot be produced by other production means, or at least cannot be achieved cost-effectively. -- Indexable insert technology for highest flexibility during cutting material selection -- Intermediate sizes and all tolerances more from page 24 available at short notice TOOL PROPERTIES -- No...
