Carbide and cutting tools join together

Mike Green, General Manager of Horn in the UK commented: “The aim of the strategic cooperation is twofold. First, it will enable both companies to combine the product and sales synergies of their organisations and, secondly, it is an opportunity for the two medium-sized, family-run businesses to grow together by developing carefully targeted markets.”

As far as Horn is concerned, the Boehlerit range of ISO turning tools perfectly complements the products from its own, internationally-leading grooving tool range. Similarly, the new Boehlerit milling cutter range will enable Horn to enhance its own portfolio of high-performance prismatic machining products by introducing a wide selection of top-performing and highly productive tools. In this way, Horn will be able to build on its leading position as a supplier of tools for technically demanding applications by establishing itself in the area of general machining as well.

The Boehlerit range of ISO turning products
New ‘chip channel’ turning geometries introduced by Boehlerit, in combination with the carbide and coating, will play a key role in improving cost-effective machining. The manufacturer used a high-speed camera to carry out a precise chip-breaking analysis for each turning application so that the best possible chip flow characteristics could be developed.

It has resulted in optimum turning geometries for machining steel as well as solutions to the problems posed by special steel grades and superalloys. New, harder gradient carbide ensures a high degree of machining reliability and a more wear-resistant; MT-CVD carbide coating results in higher cutting speeds.

Primarily, this is achieved by increasing the thickness of the patented Nanolock TiCN layer that safely bonds with the significantly harder Alpha-Al2O3 (HV2700), which has better insulating properties and increases service life by 60%, resulting in a high degree of universality in steel machining.

The LCM20T turning grade for indexable inserts enables cutting speeds of more than 200m/min to be achieved when turning stainless steels. The reliable, heat-resistant carbide exhibits high resistance to plastic deformation, as does the BCS20T grade for machining titanium. The peripherally ground CNGG 120408-BCU inserts, which are available in the Steeltec grades LCP15T and LCP25T, offer high machining reliability for a wide range of steels, as does the Supertec LC415Z grade.
