Seco’s new CW100 grade brings speed, strength to HRSA grooving
9/29/2014 7:30:00 AM

Fagersta, September 2014 – With its new whisker-reinforced CW100 ceramic insert grade for high-speed grooving operations, Seco further enhances its range of products that optimise wear resistance and toughness in the machining of challenging materials, including Inconel 718, Waspaloy and other heat-resistant super alloys (HRSA).

CW100 is an aluminium oxide-based insert with silicon carbide whiskers (Al2O3-SiCw). When dispersed into a matrix of fine-grained aluminium oxide, these extremely strong whiskers act as reinforcement, adding tensile strength and improving the fracture toughness of the brittle matrix.

An Al2O3-SiCw composition, typically made up of 25 to 50 percent whiskers, is the toughest, most thermal shock resistant of all the aluminium oxide-based ceramic materials for inserts. As a result, the CW100 offers superior wear, fracture and notch resistance as well as high hardness at elevated temperatures when machining tough materials at extremely high speeds. CW100 excels in wet or dry applications, but Seco recommends the use of concentration-level flood coolant for wet machining.

CW100 comes in the form of solid inserts. It is available on four insert geometries with widths of 3.175 mm, 6.35 mm and 7.925 mm. Furthermore, the high honed edge quality of CW100 inserts allows users to achieve superior surface finish on a wide variety of components, including casings, shafts, discs and rings for aerospace and power generation.

CW100 is part of the Secomax™ ceramics lineup, which also includes the CS100 sialon-type grade for ISO turning inserts.
