GC1130, which is the latest Zertivo grade from Sandvik Coromant, delivers high metal removal rates and secure performance levels in both wet and dry machining operations. PVD-type coating Zertivo supports GC1130’s high edge-line security and reduced flaking. In addition, a high Cr content fine-grain substrate delivers high resistance to thermal cracks, helping ensure long and reliable tool life.
Already available on CoroMill 390, CoroMill 490 and CoroMill 495 shoulder and chamfermilling systems, the technology is now available for a wider user profile.
Machine shops can use grade GC1130 inserts with CoroMill QD for deep and narrow grooving in both external and internal roughing and finishing operations. For additional groove milling requirements, GC1130 inserts can also be applied with CoroMill 331, a multi-purpose side- and face-milling cutter. This versatile tool is capable of grooving, double half side milling, shoulder milling, face milling, back-face milling, gang milling and circular ramping.
GC1130 is now offered across seven product families. Along with CoroMill QD and CoroMill 331, the insert grade is available for use with CoroMill 790 and T-Max long edge (shoulder milling), CoroMill Century (face milling), CoroMill 170 and CoroMill 176 (gear milling).
Says Björn Ericsson, project manager: “Issues such as flaking, abrupt chipping and thermal cracks are commonly encountered when milling materials in the ISO P application area, especially when faced with unfavourable toolpaths, deep cavities or when using coolant. We have developed GC1130 to help machine shops overcome the consequential effects of reduced insert life and unstable production.”
