Paul Horn GmbH presented its extensive portfolio of standard and special tools for aluminum machining in Stuttgart. From simple PKD end mills to complex modular combination tools, Horn offers a wide range of products for many applications.
With over 30 years of experience in the development and production of precision tools with hard cutting materials, Paul Horn GmbH in Tübingen presents a comprehensive PKD milling program for productive aluminum machining at AMB 2024 in Stuttgart. During this time, Horn has proven itself in numerous industries and has become an important partner in the field of PKD tools. The new PKD milling program is part of this long-standing development and complements the portfolio. Based on market experience and customer requirements, Horn has purposefully developed a complete standard program of milling tools. The standard program of the series DM 20 to DM 90 stands for process-safe machining of aluminum, non-ferrous metals, and technical plastics. With a focus on resource conservation, coordinated cutting lengths, and tool designs, the tools are available from stock.
With this product program, Horn offers a wide range of standard and special tools from simple PKD end mills to complex and modular combination tools. As a driving force, the focus is on economically thought-out solutions with high productivity, combined with Horn technology, high flexibility, and reliability. The Horn high-performance PKD cutting material consists of a refined mixture of differently sized diamond grains. The volume fraction of diamond increases, as do hardness, toughness, and cutting quality. Strict quality standards and their control are a matter of course and ensure strong performance.
Machining Aluminum
The tensile strength, elongation, hardness, and strength of aluminum can be influenced by alloying elements such as silicon, magnesium, copper, zinc, and manganese. The material can soften during machining due to heat generation, causing the cutting tool to stick and potentially be destroyed by disrupted chip flow. Therefore, proper coordination between material and cutting parameters is essential. It depends on the aluminum alloy, cutting tool, feed rate, and spindle speed, as well as the type and amount of coolant.
Aluminum - a versatile material used in all sectors of the economy. Complemented by the new PKD milling program, Horn offers a wide portfolio of optimized tools for the economical machining of the lightweight metal.
Horn Tools for Aluminum Processing
The key features of the extensive Horn program of standard and special tools are special chip geometry designs with sharp edges, polished chip surfaces, and coatings with very good sliding properties due to the strong adhesion tendency of aluminum. Carbide cutting inserts for grooving also receive a peripheral grind to ensure an extremely sharp edge. For aluminum alloys with a high silicon content, the inserts are coated. For milling, coated and uncoated circular tools and solid carbide end mills are available in the portfolio. Due to the large chip volume based on high cutting data, single-flute end mills with large chip spaces are also available. For high tool life or more complex tasks, hard cutting materials such as PKD and CVD-D with precision laser-cut edges are available. MKD-coated tools are used, for example, for high-gloss processing of mirrors or aluminum blow molds.
