March 12, 2014 - Enabling secure, unmanned production, insert grades GC4315 and GC3330 feature Inveio™, which optimizes wear resistance and endurance to promote predictability and tool life in machining processes. Performance is made possible via Inveio uni-directional crystal orientation; tightly-packed crystals create strong barrier towards cutting zone and chip. While GC4315 suits steel turning operations with high speeds and extended time in cut, GC3330 is used for milling in cast iron materials.

PUNE, India -- The Technical Breakthrough in Material Science That Provides Inserts With Exceptional Wear Resistance and Tool Life

On March 3rd, Sandvik Coromant introduces new insert grades for steel turning and cast iron milling with Inveio, the technical breakthrough in material science that provides inserts with exceptional wear resistance and tool life. In today's manufacturing, predictability is becoming increasingly important. Production that runs smoothly, without unexpected interruptions, opens the way for secure unmanned production and high machine utilization, a cornerstone for profitable production processes.

Following the successful introduction of the insert grade GC4325 in October 2013, Sandvik Coromant now extends that assortment and introduces the new grades - GC4315 and GC3330. All three grades feature Inveio that brings endurance, predictability and long tool life to the machining process.

The technical breakthrough

The performance of these grades is made possible by the Inveio uni-directional crystal orientation. Normally, the crystal orientation in inserts' CVD alumina coating is random. The breakthrough came when Sandvik Coromant found a way to control the crystals, making them all line up in the same direction - towards the top surface. These tightly-packed crystals create a strong barrier towards the cutting zone and chip.

The result is grades with incredible wear resistance and cutting edges that stay in shape for long times in cut. The long, predictable tool life of GC4325, GC4315 and GC3330 enables secure unmanned production with high metal removal rate.

Application area

GC4325 is the first choice grade for steel turning. When GC4325 reaches a limit in metal removal rate due to high speed and long time in cut, GC4315 withstands the high cutting temperatures that occur. GC3330 is the first choice grade for milling in cast iron materials.
