With over 30 years of expertise in developing and manufacturing precision tools from ultra-hard cutting materials, Horn provides a comprehensive selection of PCD milling cutters designed for efficient and high-performance aluminium machining.

Covering a range from simple end mills to advanced modular combination tools, the latest additions are engineered to address the specific challenges of aluminium machining, ensuring superior performance in chip formation, cutting dynamics, and surface quality.

The mechanical properties of aluminium, including tensile strength, elongation, hardness, and yield strength, are influenced by alloying elements such as silicon, magnesium, copper, zinc, and manganese. During machining, heat buildup can soften the material, leading to adhesion and potential tool damage.

To prevent this, it is crucial to optimise cutting feed rates, spindle speeds, and the type and quantity of coolant used. Horn's expert engineers offer guidance on selecting the ideal machining parameters for specific aluminium alloys.

In addition to aluminium, Horn's DM range is well-suited for machining other non-ferrous metals and technical plastics. The PCD grade features an advanced blend of diamond grains of varying sizes, enhancing hardness, toughness, and edge quality as the diamond content increases. Manufactured in Horn's Tübingen facility in southern Germany, these tools undergo stringent quality control, ensuring precision-lasered cutting edges that deliver exceptional performance and long service life.
