materials & tools Re-sharpening service for PCD tools Efficiency concept for high performance machining tools Now of all times, a reliable and fast service is needed to minimise costs - resources must be saved, and inventories must be kept as manageable as possible. With its headquarter in Hanau, Germany and production sites near Chemnitz, Germany and in Michigan, USA, LACH DIAMANT has extensive know-how regarding development, production, and application of polycrystalline diamond tools since 1973. Today, state-of-the-art production and re-sharpening services allow LACH DIAMANT to further optimise proven tool designs and geometries for every application which subsequently results in increased durability, better surface quality and higher feed rates. LACH DIAMANT, diamond pioneer since 1922, also provides this expertise for products from other manufacturers. The service concept includes all machining tools such as PCD-tipped inserts, end mills, monoblock milling cutters, drilling tools, reamers and similar tools; the offer includes Inspection of a PCD monoblock milling cutter at the LACH DIAMANT facility in Lichtenau near Chemnitz CBN, CVD or mono-natural diamond-tipped inserts and mill ing tools. LACH DIAMANT emphasises that this service offer also includes repair and/or re-tipping of tools and saws. It is the top priority to make the use of high performance tools more cost efficient, also by way of service. further information: www.lach-diamant.de Universal NGU chipbreaker for positive insert geometries The versatility and reliability of cutting tools is becoming increasingly important not only for turning of components for the automotive industry, but also in many other areas of application. As a solution to these increasing demands, Sumitomo has developed the general-purpose NGU chipbreaker for positive M-class inserts. As already known from negative insert shapes, the positive NGU type also features extremely stable chip control and covers a very wide range of applications from finishing to light interrupted cutting. Excellent chip control despite different cutting conditions The chipbreaker shape is characterized by a wide chip pocket, which provides improved chip control under different cutting conditions. This prevents the chips from being trapped during the machining process and ensures a stable process flow. The new chipbreaker geometry is available for use in both steel materials and stainless steels. Low cutting forces reduce vibrations The chipbreaker design provides excellent chip control and is designed to reduce cutting forces and vibrations during machining. This reduces cutting edge stress and ensures a stable machining process in various applications and cutting conditions. Improved fracture resistance for lower machining costs The multi-stage chip breaker ensures excellent sharpness and toughness, which significantly improves cutting edge stability. As a result, NGU chipbreaker reduces the frequency of tool changes and reduces machining costs. further information: www.sumitomotool.com 14 no. 3, September 2020
materials & tools A fresh take on inside deburring Welded pipes with a longitudinal seam are frequently used for complex applications in different industries, for instance, the automotive or petroleum industry. To fulfil the complex requirements with regard to tensile strength and dimensional tolerance, the welding burr is often removed at the pipe production stage. The new Boehlerit internal scraper rings constitute the perfect solution for the clean and efficient deburring of welded pipes. The Boehlerit internal scraper rings offer a range of benefits, guaranteeing economic efficiency, precision and outstanding performance throughout. The internal deburring tool is suitable for multiple uses due to its adjustable blade. It also comes with an optimised cutting geometry and top-of-the-range coating for extended tool life and tight dimensional tolerances on the finished pipe. The Boehlerit internal scraper rings are compatible with the most frequently found tool systems for cutting rings on the market and with the standard dimensions for pipes with a diameter from 12 - 130 mm (cutting ring diameter of 6 - 50 mm), all available ex-warehouse. In addition, Boehlerit, in cooperation with Ernst Blissenbach GmbH, offers mechanical scarfers for the removal of internal welding beads, with or without integrated notching wheels, as well as other internal deburring tools for pipes. All of them Boehlerit internal scraper rings ideally complement the Boehlerit tool systems for the machining of welding seams, threads and pipe ends as well as the deburring of welding beads. further information: www.boehlerit.com KREBS & RIEDEL Schleifscheibenfabrik GmbH & Co.
