Milling cutters for extremely long service life

Whatever the vehicle, a sleek look is ever-popular. So, from season to season each new generation of models seemingly gets more and more streamlined. In the automotive industry, steel materials are increasingly being replaced by aluminium alloys, particularly when it comes to sports models. This helps manufacturers to work towards their efficiency targets, as well as requirements for dynamics that they have set themselves. Although aluminium is good to work with when it comes to machining, the material does have its drawbacks, which tool developers try to minimise using specially adapted tool systems.

Hard grades – equally strong in roughing and finishing
In order to be able to better serve broad application fields such as the non-ferrous metals sector, CERATIZIT has added around 2,500 items to its milling cutter range that are designed exclusively for these applications. These items are based on special substrates, paired with specially adapted geometries and sturdy coatings. Even though non-ferrous metals are comparatively soft, CERATIZIT nevertheless uses hard grades such as DLC coatings for its AluLine milling cutters. With HV 0.05 = 6000, the coatings provide at least 60 to 80 percent of the hardness of natural diamonds producing outstanding performance in terms of service life in roughing and finishing operations. As a result, milling cutters are protected from damage caused by built-up edges or abrasive alloy accretions – something that is absolutely essential in series production, for example. If you do not want to use coolant, this is not a problem for DLC: this powerful coating demonstrates particularly impressive performance in dry machining applications – it runs as smoothly as if it were using lubricant!

CERATIZIT – With passion and a pioneering spirit for carbides
For more than 95 years, CERATIZIT has been a pioneer in the field of ambitious hard material solutions for machining and protection against wear. The private company, with registered offices in Mamer, Luxembourg, develops and produces highly specialised cutting tools, indexable inserts, rods made from hard materials and wearing parts. We are the global market leader in various application segments for wearing parts and are successfully developing new carbide, cermet and ceramic grades, for example in woodworking and stone working.

With more than 9,000 employees at 34 production facilities worldwide and a sales network with over 70 branches, the Group is a global player in the carbide sector. Our international network also includes subsidiaries KOMET, WNT, Becker Diamantwerkzeuge and Stadler Metalle, as well as the CB-CERATIZIT joint venture. As a technology leader, we continuously invest in research and development and hold over 1,000 patents. Our innovative carbide solutions are used in the mechanical engineering and tool making sectors, in the automotive industry, the aviation and aerospace industry, and in the medical industry.

We are represented on the market by our seven flagship brands, Hard Material Solutions by CERATIZIT, Toolmaker Solutions by CERATIZIT, Tool Solutions by CERATIZIT, Cutting Solutions by CERATIZIT, KOMET, WNT and KLENK.
