The new BCU1 series of Hofmann & Vratny offers reliable quality for price-sensitive applications. The milling cutters are designed for use as all-rounders due to proven geometries. Thanks to the new BetaUni Iron universal coating, the BCU1 series is suitable even for machining demanding materials in roughing and finishing operations. A special fine-grain substrate ensures reduced cracking and high resistance to cutting edge breakouts. The special edge preparation ensures a homogeneous cutting edge throughout and thus guarantees a uniform distribution of cutting forces. Wear is controlled and even. Likewise, an improvement of the produced surface on the component is achieved.

Decathlete versus pole vaulter: The BCU1 series compared to individual Expert series.

The tools of the BCU1 series are perfect all-rounders, the Expert models convince as highly specialized milling cutters. The BCU1 milling cutters are virtually the decathletes in the manufacturer's product range, the Expert series were constructed for top-class performance in the respective individual disciplines. Particular strengths of the BCU1 series are the excellent price/performance ratio and the universal application possibilities of the tools. The milling cutters of this line can be used in different materials with very solid results.

To illustrate the difference and performance of the BCU1 series compared to the Expert series, various scenarios were tested at Hofmann & Vratny. Parameters such as material suitability, milling performance, machining volume, tool life and tool costs were examined. The result: The BCU1 series was able to confirm its universal suitability across the board in the internal tests.

BetaUni Iron: the ideal coating for universal machining.

BetaUni Iron is an AlCrN-based coating that was developed for demanding universal machining. Thanks to a simple and proven composition, it delivers convincing results for price-sensitive applications. Due to its nanostructuring, the coating enables a wide range of applications and is suitable for use on a wide variety of tool types, such as mould tools, shank tools and roughing tools. As a reliable universal coating, it delivers impressive results when machining non-ferrous materials, stainless steel, steel and cast iron. Even the processing of difficult-to-machine materials such as titanium, Inconel and hardened steel is feasible in the secondary application. It is even possible to machine hard-to-cut materials such as titanium, superalloy and hardened steel in secondary application areas.
