Insert grade improves parting and
grooving
A multi-layered metal cutting insert is achieving improved performance in parting, grooving, turning and profiling operations in a wide geometry range.
Sandvik Coromant has introduced its GC1125 grade has been introduced to its parting and grooving tooling system, CoroCut 1-2 edge, Sandvik claims that the multi-layered material improves performance in parting, grooving, turning and profiling operations in a wide geometry range The GC1125 has a good all round ability in machining steel and stainless steels and excels when machining cast iron and HRSA materials owing to what Sandvik describes as a 'technological breakthrough' in coating and substrate technology

Cutting tool catalogue includes free methods CDs
A comprehensive catalogue of tools and methods for the die and mould making industry includes two free CDs - one containing a metal cutting data module to optimise cutting data.
The combination improves wear resistance and security, either when running at higher cutting speeds or for a longer time in cut.
The coating is PVD (physical vapour deposition) with TiAIN layers, including properties designed for the GC1125's wide application area.
New, fine grained substrate optimised for steels and stainless steels has improved hardness and increases cutting capabilities.
GC1125 enables machine shops to do more with one grade.
Its wide geometry range offers improved performance to a larger number of machining operations, as follows.
* Parting-off - 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.
* 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.
* Cutting profilies in steels, cast iron and stainless steel - two geometries are available: RM for profiling in all materials and a first choice in stainless; RO for outstanding chip control at low feeds.
* Turning steel - the TF has positive geometry for good chip control and surface finish, reducing the risk of built up edges.
Sandvik said that performance tests in a grooving and parting operations against the best previous grade demonstrated the improved performance afforded by GC1125.
For example, grooving on a transfer gear using the same cutting data, GC1125 was able to produce almost twice the number of components.
In a parting comparison test on parting off a pinion shaft, in the same conditions, GC1125 was able to run for a longer time in cut than the best competing grade.
