Seco releases MK2050 grade for reliable, productive cast iron milling
4/15/2013 4:00:00 PM

Fagersta, April 2013 – Seco has introduced MK2050 developed specifically to address the challenges of milling cast iron. Ideal for manufacturers serving the automotive and general engineering segments, MK2050 maintains strong performance across variances in cutting conditions and material heterogeneity.

MK2050 features a hard, fine WC-grained substrate with low binder phase content, along with a wear-resistant PVD TiSiN-TiAlN nanolaminate coating. This newly developed combination optimises the grade's balance between toughness and hardness for ductile and cast irons. The end result is high productivity with long, predictable tool life, even in applications that include unstable machining conditions.

A flexible grade, MK2050 can be applied with or without coolant to all types of cast irons. MK2050 inserts run optimally at low-to-medium cutting speeds and feeds, but also can provide effective performance at high speeds and low feeds. In test applications, MK2050 has reduced total cycle times by over 50% when compared to similar insert grades.
