For high-speed machining of non-ferrous metals, ISCAR offers a wide range of PCD cutting inserts, and with the new ceramic plates, users can machine hardened materials, superalloys, and cast iron even more efficiently.
Due to their extraordinary hardness, temperature resistance, and chemical stability, ISCAR's ceramic tools enable maximally productive machining processes. Since the cutting material retains its properties even at extreme temperatures, users benefit from wear resistance and a large time volume at high cutting speeds.
New range of grades for challenging machining tasks
"With more than 300 new cutting plates in our portfolio, every user will find the perfect tool for their process," says Frederik Schmalbach, Product Manager Non-Rotating Tools at ISCAR Germany. "By precisely selecting the cutting material tailored to the process, long tool life is achieved even with hardened steels, castings, and superalloys." A wide range of cutting inserts in various shapes based on silicon nitride (Si3N4), aluminum oxide, and whisker ceramics, as well as the newly developed Bidemics, are available to meet even very specific requirements.
Specifically for cast iron machining, ISCAR has white aluminum oxide ceramic in its program. Due to its extraordinary wear resistance, this cutting material is particularly well-suited for efficient high-speed finishing. "In the black mixed ceramic, we incorporate titanium carbide (TiC). This increases the toughness of this material," explains the product manager. This makes the cutting material ideal for semi-finished and finished machining of hardened materials and cast iron. "For high-speed roughing of cast iron, however, silicon nitride inserts are the first choice," says Schmalbach. This cutting material is extremely resistant to notch wear and thermal shock. As a result, users achieve machining speeds of up to 1,000 meters per minute.
To machine sintered metals and superalloys, ISCAR offers whisker-reinforced grades in addition to SiAlON ceramics. "The incorporation of whiskers, which are needle-shaped crystals of silicon carbide with a few micrometers in diameter, improves wear and fracture resistance," explains Schmalbach. ISCAR's latest innovation for high-temperature-resistant superalloys is the Bidemics cutting plates. "Thanks to its physical properties, this patented cutting material even outperforms the whisker ceramics typically used for this purpose," the product manager enthuses, adding: "They allow significantly higher machining speeds and enable even better surface qualities. Additionally, they are wear and notch resistant." The inserts produce short chips that can be easily and efficiently evacuated. The combination of high hardness, very good thermal conductivity, and improved strength also leads to significantly longer tool life at the same cutting values.
