Seco (Troy, MI) has expanded the roughing and semi-finishing performance capabilities of its Secomax CS100 sialon ceramic grade by adding inserts with T-style edge preparation to the line. Featuring a free-cutting, extremely sharp geometry, the new inserts bring strength, stability and performance longevity to the machining of nickel-based superalloys in unstable conditions. Well suited for turning applications that require tight tolerances and low cutting forces, the T-style (chamfered) CS100 inserts are available in 20-degree chamfers that range from .002" - .004" (0.05 mm to 0.1 mm) in width. The sharp, negative reinforced cutting edges on these inserts absorb some of the high cutting force and pressure that would otherwise be placed on the machine setups and workpieces. As a result, these inserts eliminate the risk of workpiece deformation, especially in thin-walled components, as well as reduce excessive vibrations that shorten tool life and negatively impact surface finish.
