Parting and grooving grade boasts wider application

Sandvik Coromant’s new GC1125 grade for its parting and grooving tooling system, CoroCut 1-2 edge, delivers a wider application area and the capacity to handle improved cutting data. GC1125 is a simpler option, enabling machine shops to do more with one grade. Its wide geometry range offers improved performance over a larger number of machining operations. The new grade has good all-round ability and provides the means to improve performance in a wide geometry range across many parting, grooving, turning and profiling operations. It is the first choice for application in steel and stainless steels and excels when machining cast iron and HRSA materials. These advantages result from a technological breakthrough in coating and substrate technology. The combination improves wear resistance and security, either when running at higher cutting speeds or for a longer time in cut. The coating is new, PVD with TiAIN layers,and a new fine grained substrate optimised for steels and stainless steels has improved hardness and supports increases in cutting data. In parting, it is optimised for steels, stainless steels and HRSA materials, a first choice in CF and CR geometries. CF is the low feed choice, giving excellent chip control and surface finish, CR the strong geometry for parting off bars and interrupted cuts at high feeds. In grooving, GC1125 offers a good choice for steel and stainless steels in the GF geometry, offering accuracy and tight tolerances due to its sharp cutting edge. For profiling in steels, cast iron and stainless, two geometries are available: RM for profiling in all materials and a first choice in stainless; RO for outstanding chip control at low feeds. When turning in steel applications, the TF has positive geometry for good chip control and surface finish, reducing the risk of built-up edges.
