The Standard for Hard Machining

With its nano structure, our Eifeler SISTRAL high-performance coat is THE standard for hard, dry and high-speed machining applications. Improved performance parameters and endurance included! Thanks to its specially developed specific layer structure and composition, SISTRAL excels through extreme wear resistance to meet even higher machining demands.

Increased Endurance and Cutting Speed

SISTRAL’s chemical resistance, low tendency of crack formation, low thermal conductivity coefficient, extremely high oxidation resistance and hot hardness naturally result in excellent performance indicators. The interplay of these special layer properties allows for even better performance in all areas of application for which standard AlTiN coatings used to be the preferred solution.

Machining Under Difficult Conditions

One of the SISTRAL coating’s main benefits is improved surface quality. This also makes the coat an excellent option for machining tasks such as milling and turning under conditions that bring other coats to the limits of their thermal and mechanical stress capacity. Other areas of application: High-performance machining of very abrasive or hard materials (e.g. Steel from > 54 to > 62 HRc) in dry high-speed operation. With its nano-structure, this PVD coating is also very well suited for the area of punching – for example of VA qualities.
