Sandvik Coromant has launched GC1230, a new grade for indexable milling. Designed for high metal removal rates in stable conditions, GC1230 is set to become your go-to solution for steel milling.
Developing a grade to excel in both edge line toughness and wear resistance is a rare feat. However, this is precisely what has been achieved with our new steel milling grade GC1230 produced with Zertivo coating process technology. “GC1230 has a ground-breaking coating innovation delivering exceptional performance with security, predictability and sustainability. It is the first choice for steel milling applications,” says Wayne Mayson, Global Product Application Manager for Grades at Sandvik Coromant.
Wayne Mayson continues: “This new steel milling PVD (Physical Vapour Deposition) grade innovation comprises of a nano multi-layer TiAlN + TiSiN coating with improved adhesion — a coating technology that is improved in all directions of performance capability. In short, it is stronger for longer whether wet or dry steel milling applications”.
GC1230 excels in every aspect, whether you seek to extend tool life, boost productivity, or embrace a more sustainable milling approach. The new coating of GC1230 provides unbeatable edge line toughness, resulting in a significantly extended tool life which means more pieces per edge. Thanks to the high heat-resistant capabilities, you can maximize cutting speed to achieve high metal removal rates and boost productivity by reducing machining and cycle time. Its outstanding performance in dry machining conditions makes it a sustainable alternative to coolant-based methods, contributing to more eco-friendly milling.
Comprehensive tests conducted between the existing grade GC1130 and the new grade GC1230 demonstrate the latter’s superior strengths and versatility — it is strong all over. The new grade builds upon the success of grade GC1130 but has a wider application coverage due to increased toughness and wear resistance capabilities at even higher cutting data. The edge line security of GC1230 stands out but heat resistance, crater and wear resistance, and tool life in both P1 and P2 material are also far superior to its predecessor.
Optimized for light roughing to finishing operations, GC1230 is ideal for a wide range of applications, from general to more challenging tasks such as square shoulder milling, complex tool paths and deep cavities, in both wet and dry conditions. It is suitable for all industry segments and various component features.
