Sandvik Coromant GC4325 grade offers the predictable life needed for unsupervised production
Sandvik Coromant has introduced GC4325, a coated cemented-carbide grade for steel turning that provides extremely high process security through its ability to retain an intact insert edge line. The grade has the potential to increase cutting speeds and extend predictable tool life with very high reliability over a broad ISO P25 application area.
Predictability has become increasingly important in today's machining, especially where there is limited supervision in production. The technological advances represented by the Sandvik GC4325 grade will help users resist the temptation to use unnecessarily cautious cutting-data levels.
There are always a number of threats to the edge line remaining intact long enough in steel turning. One challenge is the breadth of the ISO P25 application area, which includes several very different materials, from ductile low carbon steels to high alloy hard steels, bar material to forgings, castings to pre-machined parts.
The GC4325 grade is capable of maintaining the insert edge line at higher temperatures, which translates into the capability for higher cutting speeds with added security through more predictable, longer tool life.
