Keeping up with the latest steps in steel milling, the cast iron field has also made new progress through the use of high-universal grades that continuously improve toughness and wear resistance. These two grades are used in various processes determined by the characteristics of the cast iron milling field.
Grade GC1020-Sandvik Coromant's excellent cast iron milling blade material with all kinds of gold. It can be used as the new first choice for ductile cast iron and all wet cast iron machining. The robust PVD coating ensures a high cutting speed and reduces wear. It is a weapon under unstable conditions. It is the new first choice for CoroMill 390 milling cutters.
Utilizing the ultra-thick protective coating of the milling insert, GC3220 has greatly improved durability and wear resistance, and greatly optimized the dry cutting of gray cast iron. GC3220 is designed for the use of CoroMill milling cutter range, especially for shoulder milling and face milling of large diameter cutters. It provides smooth and reliable cutting performance.
These two grades enhance the existing geometry, provide CoroMill with a wide range of inserts, and increase the productivity of cast iron milling.
