Sandvik Coromant’s high-performance, sharp-edge grade, the GC1115, is designed to ensure secure and reliable performance in applications ranging from aerospace to general engineering. The grade combines the toughness and heat resistance of fine grain cemented carbide with the wear resistance of a PVD coating, making it an effective choice for predictable production systems where unstable conditions are likely to occur.

Understanding how inserts are made provides valuable insight into how their performance can be optimized.

Not only do wiper inserts accomplish smooth surfaces—and if the material allows, they will eliminate a grinding operation—but these additional radii are also designed to double the feed rates of roughing and semi-finishing operations while achieving the specified surface finishes.

Businesses need to prepare for an upswing as they do a downswing. Staffing, materials and production are just a few of the areas that need to be adjusted—but when? We at Sandvik Coromant think is should be done now.

Sandvik Coromant is broadening its variety of hard part turning inserts with CB7025, a strong grade optimized for interrupted cuts in case hardened steel. The grade's fine grain CBN controls wear and mechanically interlocks insert corners to provide strength and security superior to standard insert edge designs, according to the company. These properties enable higher machining speeds, as well as the ability to finish components in one pass while retaining surface quality.

Sandvik Coromant will introduce its iLock at the September EMO exposition in Germany as a way of improving indexable insert stablility when cutting metal.  

Additions to the Sandvik Coromant family of heat-resistant, super alloy cutting tools include the CC6060 and CC6065 inserts. The ceramic grades of round inserts are capable of running at four to six times the speed of conventional carbide inserts, the company says. The CC6060 is optimized to provide productivity benefits with larger diameter components and longer lengths of cut.

Sandvik Coromant's versatile inserts and tooling are available, including the CB7025, a strong grade milling insert for interrupted cuts in case-hardened steel. It consists of a fine grain CBN that controls wear and mechanically interlocks insert corners to provide strength and security superior to standard insert edge designs, the company says. The CC6060 and CC6065 grades of round ceramic inserts achieve four to six times the cutting speed of conventional carbide inserts in medium to roughing operations.

Sandvik Coromant offers insert grades that are designed to boost turning productivity and performance, such as the GC4235 that is said to provide excellent security in both steels and stainless steels, even when working in unstable and demanding conditions. The CC6060 and CC6065 grades of round ceramic inserts achieve four to six times the cutting speed of conventional carbide inserts in medium to roughing operations. The CB7025 is said to optimize cutting results in light to heavy interrupted cuts of case-hardened steel.

Sandvik Coromant's new LC insert geometry improves chip evacuation to boost productivity in difficult to machine materials. While conventional geometries cause frequent chip jamming, the LC avoids these interruptions to production, according to the company. By lowering the risk of chip jamming, the LC insert geometry is a step towards trouble-free turning of low carbon steels.
