Sandvik Coromant has introduced two new grades for machining cast iron. GC3225 and GC3210 form a new insert grade chain covering all cast iron turning operations for both grey and nodular cast iron materials.
GC3225 is a first choice grade for the cast iron turning application area. It is designed to provide secure and trouble-free machining even in the most difficult conditions.
GC3210 is a grade with high flank wear resistance suitable for turning in all cast iron materials, in good to average machining conditions. It enhances reliability and productivity in intermittent cuts, high cutting speeds, wet or dry machining, machined surface or light cast skin.
To provide the edge-line security and wear resistance necessary to optimise performance, GC3225 and GC3210 feature a CVD coating combined with a fine-grained hard substrate. Additionally, their innovative design utilises optimised micro-geometries to facilitate light cutting action, hence reducing cutting forces and improving tool life.
The results of tests conducted at customers have shown remarkable results. GC3225 has more to give when other inserts reach the end of their life. By using the insert in machining of nodular cast iron it was possible to increase tool life by 70% compared to a competitor grade. GC3210 has been tested in the machining of differential case covers with some outstanding results. After changing to GC3210 instead of a competitor grade, it was possible to increase tool life by 38%.
