SISTRAL®
SISTRAL® PVD Coating
Our new nano-structured high performance layer
SISTRAL® – on the basis of our very successful more advanced EXXTRAL®,
• for even higher requirements in case of machining, in the foreground
• for the dry high-speed processing of hardened materials (>54 HRC).
SISTRAL® PVD Coating, which is also anthracite colored, is characterized by a very high hardness that still protects against wear also at high temperatures, and an exceptional oxidation stability.
Applications:
Cutting tasks (milling, drilling, turning, sawing, etc. ) under in-service conditions, where other layers reach the limits of thermal and mechanical loading capacity. High-performance machining (HSC) of very abrasive or hard materials (steel > 54 HRC) in dry high-speed application. SISTRAL is also an excellent coating for reaming applications.
Deposition technology:
SISTRAL® is deposited in latest eifeler PVD ARC systems. With temperatures of approx. 450° C high-performance cemented carbides are mainly coated. The coating of tool steels and HSS is also possible!
