New T-style sialon ceramic inserts from Seco excel in unstable conditions

Seco 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 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 0.05 mm to 0.1 mm in width. The sharp, negative reinforced cutting edges on these inserts help 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. The characteristics of the T-style inserts also complement the existing S-style (chamfered and honed) CS100 products designed to handle high cutting forces in rigid, stable machining conditions.

Collectively, the T-style and S-style inserts in the CS100 line have high abrasion resistance and superior toughness that extends tool life and allows for high cutting speeds when processing challenging materials such as Inconel, MAR, RENE and Waspaloy. In other words, manufacturers, especially those in aerospace and power generation, using these inserts benefit from high productivity, consistent quality and a low cost per part.

Furthermore, Seco has added new ceramic insert holders to its comprehensive product portfolio. Available in standard shaft and Seco-Capto styles, these holders have special pocket designs and clamping systems that easily accommodate the different thicknesses and missing centremounting holes that are common with these types of inserts.
