The Komet Group is presenting numerous innovations at the AMB 2016 event at Stuttgart this month.

Machining tools are becoming increasingly efficient. This is what the Komet Group, manufacturer of precision tools is demonstrating at AMB 2016 (September 13-17), presenting numerous innovations under the trade fair slogan ‘Total Productivity Solutions’. Highlights include the growing range of milling tools that can also be used in generative manufacturing processes, as well as a completely new indexable insert reaming tool and unique expansions of the Komet Kub Pentron® drill. Other attractions include the numerous innovations in mechatronic tools and ultra-hard cutting tool materials as well as the Komet ToolScope assistance system, which bridges the gap from machining to Industry 4.0.

The cutter holders in the completely redesigned PCD milling cutters are manufactured using the generative process of laser melting, which means that these new tools can offer feed rates up to 50% higher than before. 3D printing enables up to twice as many cutting edges to be created – regardless of diameter. Komet is also utilising the structural flexibility provided by the additive manufacturing process to create a perfect design for the course of the coolant channels inside these milling cutters. Curved channel routes now reduce pressure loss in the coolant and are positioned precisely in such a way that every cutting edge is supplied with coolant from a separate channel.

Aside from the new production process, the company is also expanding its milling range with new designs, such as the Komet hi.aeQ 45° face-milling cutter, which has a feed rate of up to 40% higher than a shoulder milling cutter. It is also launching new PCD milling and thread milling tools to standard versions that can be particularly productive when used in applications involving lightweight construction materials.

Dimensionally accurate – even for large drilling depths

For years, the Komet KUB Pentron® solid drill has stood for precise drilling under extreme conditions. This tool was previously only available in the 4xD and 5xD length/diameter ratios, but the Besigheim tool spe-cialists have now also developed 2xD and 3xD versions so that the high-performance indexable insert drill can be used in an even more versatile manner. The CS (Custom Solution) variant has drawn particular attention with its diameter /length ratio of 6xD.

Facing head with direct position measuring system

Mechatronic tools such as precision adjustment heads, facing heads and the KomTronic® U-axis systems, available in several variants, are one of the specialities of the Komet Group. A patented direct encoder has been available as an optional extra for U-axes and the purely mechanical KomDrive facing heads for two years. In order to enable encoding to take place directly on the slider, the encoder also takes disturbance variables of mechanical elements into account, such as the drive element tolerances, the temperature range and wear. The control system can respond to the measurement data immediately, providing accuracy to +/- 3 µm and thereby enabling outstanding machining quality to be achieved.

Tool and process expertise from a single source

Komet Brinkhaus GmbH has been part of the Komet Group for more than three years. As a result of the interaction between tool experts and process monitoring specialists, it has been possible to further develop the ToolScope process monitoring system into an integrated assistance system in terms of Industry 4.0. It monitors the internal signals from the machine, detects events such as tool changes or machine stoppage and is able to calculate parameters and deduce trends.
