CeramTec Adds New Ceramic for Cast Iron

CeramTec is expanding its portfolio of high-tech cutting materials with silicon nitride ceramic LKT 100 for highly efficient turning of cast iron materials. The new cutting material combines the toughness typical of silicon nitride ceramics with increased wear resistance. The increased performance is achieved through an innovative manufacturing process that alters the cutting material’s composition in the outer functional zone.

“LKT100 combines high strength with excellent wear resistance and particularly high notch dent resistance. It allows large metal removal rates for favourable 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 of Cutting Tools. “Typical workpieces include brake discs, brake drums and other mass-produced components made of cast iron, or E-motor shells made of GJL that must be drilled out. The LKT100 is suitable for roughing and rough-finishing with non-uniform and fluctuating allowances and creates high chip cross-sections.”

The LKT 100 cutting material is designed for cutting speeds of 400 to 1,000 metres per minute, with a cutting depth of up to four millimetres and feed rates of 0.15 to 0.5 millimetres. The optimal data depends on the actual application. wire / Halle 11 / E02
