Reaming: Modular design and ease of handling

Cost efficiency from the DIHART® Plug´n ream toolbox
from the KOMET GROUP

The DIHART Reamax® TS tooling system satisfies the widest variety of demands that users expect in terms of quality and cost efficiency when reaming. The system saves on tooling costs, because of its modular structure and its easily exchangeable reaming heads allow it to be used for a wide variety of components, and its surprisingly good performance is demonstrated, for example, in an extremely long tool life. What is also appreciated at Hermesmeyer & Greweling is the concentricity integrated in the adjustable DIHART DAH® Zero toolholder.

"We have been working with the drilling and reaming tools from KOMET GROUP for many years and seen time and again how they have allowed us to move forward", explains Karl Heinz Greßmeyer, the foreman responsible for production at Hermesmeyer & Greweling. The Marienfeld-based German company specialises in the machining of components used in plant-, mould-, machine- and toolmaking. Greßmeyer explains what he means by moving forward by using the example of the new multi-blade DIHART Reamax® TS high-performance reamer which he acquired in the course of machining large-size components for wind power stations. He draws particular attention to torque supports (GGG 40) where the Tooling System is used with a DST (Cermet) 30 millimetre diameter reaming head. A KOMET ABS® hydraulic expansion chuck was used to accommodate the tool and an adjustable DIHART DAH® Zero holder was used to adjust the concentricity. With regard to the tool life achieved, and if considered from a sporting perspective, Greßmeyer's leap forward from a previous 4,350 millimetres to nearly 40,000 millimetres seems positively Olympian. This alone satisfies a central requirement in high-performance reaming and is the primary factor in determining cost efficiency. However, this tooling system possesses several other positive features that must be taken into account.
