New silicon nitride ceramic

The new cutting material combines the toughness typical of silicon nitride ceramics with increased wear resistance. This increased performance behaviour is achieved through an innovative manufacturing process which allowed us to influence the composition of the cutting material in the outer functional zone.

"LKT100 offers very good tenacity with excellent wear resistance and particularly high notch dent resistance. It allows large metal removal rates and thus enables advantageous cost-per-part machining results. We have developed the new cutting material for turning and drilling GJL-materials in smooth to heavily interrupted cuts," explains Johannes Schneider, senior product manager cutting tools. "Typical workpieces are, for example, brake discs, brake drums and other mass-produced components made of cast iron or also E-motor shells made of GJL that have to be drilled out. The LKT100 is suitable for roughing and rough-finishing with non-uniform and fluctuating allowances and furthermore creates high chip cross-sections."

The LKT 100 cutting material is designed for cutting speeds of 400 to 1000 metres per minute, with a cutting depth of up to 4mm and feed rates of 0.15 to 0.5mm. The optimal data depends on the actual application.
