Ceramics can perform hard turning too

Kennametal UK product story

Hard turning does not always demand use of expensive CBN - Kennametal Hertel recommends its KY1615 TiCN based fine ceramic grade for machining pre-hardened components.
Hard turning does not always demand use of expensive CBN - Kennametal Hertel recommends its KY1615 TiCN based fine ceramic grade for machining pre-hardened components.
Hard turning - an area of operation for CBN? Cutting materials made of cubic boron nitride today set the standard in hard machining when tool life is the sole yardstick - but at what cost? Good mixed ceramic grades achieve similarly high metal-cutting values in the performance scale.
The market price for this cutting material group is, however, much lower than that for CBN.
The new Kennametal Hertel grade KY1615, a TiCN-based fine-grain ceramic grade, was developed for machining hardened and tempered, case-hardened and induction-hardened components.
This grade has undergone industrial trials around the world, machining drivetrain components for cars, shape rolls made of chilled cast iron and anti-friction bearings.
The development engineers attached special importance to high-temperature strength and a stable, even cutting edge.
This grade is worth trying if the price/performance ratio is decisive.
