New Insert Grades and Geometries Extend Your Turning "Sweet Spot"

Manufacturers turning a wide range of materials face extreme challenges daily. They know that the most efficient machining means finding the "sweet spot." Too slow may increase attention to detail but also increase opportunities from speedier competitors. Accelerating speeds and feeds may actually lower efficiency if you're using up tooling faster or stopping your turning center more often to clean out stringers.

The WIDIA Victory™ family of turning inserts from WIDIA has expanded with new geometries and grades that extend your turning sweet spot by delivering excellent chip flow that results in smooth machining, improved efficiencies, and extended tool life.

For difficult-to-machine materials like Inconel and Rene in complex aerospace applications or cobalt-chromes and high-alloy stainless steels in precise medical applications, the new WIDIA Victory FS geometry is a ground, high positive design best used in finishing tasks where surface finish and minimizing part deflection are critical. Precision grinding, proprietary nose geometry, and optimized edge treatment result in an insert that retains its high-quality cutting edge with minimal heat generation and good chip breaking at finishing parameters. Its high rake angle reduces cutting forces and also reduces built-up edge.

The --FS is available in WS10PT, a high-performance PVD grade. This grade utilizes a two-layer coating that increases coating integrity and reduces depth-of-cut notching, increasing productivity and dependability. All inserts in the WS10PT grade undergo a post-coat treatment to increase compressive stress and improve edge toughness. This delays built-up edge and results in longer tool life. WS10PT is available in other geometries including the UR geometry.

Stainless Steel Performance WIDIA's Universal Roughing (UR) geometry is specifically designed to increase roughing and medium turning performance in stainless steels and steel workpieces. Its unique chip breaker and rake profile design without inflection points breaks up stringers without concentrating cutting forces that result in breakage. Its positive rake angle further reduces cutting forces while improving depth of cut notching resistance. Together with a multi-layer coating with a ZrCN top coat for both extended performance and improved wear identification, the result is the ability to increase speeds or feed rates efficiently, increasing productivity and reducing cycle times.

WIDIA grades WP15CT, WP25CT, and WP35CT are also available in the Universal Roughing geometry to particularly improve performance on steel workpieces. Emphasizing an excellent combination of toughness and cutting performance, WP15CT is universally applicable on all finishing, medium machining and light roughing steel operations, wet or dry, interrupted and non-interrupted.

WP25CT is best applicable on all medium to light roughing operations, wet or dry on interrupted and non-interrupted cuts.WP35CT is the best choice on all roughing and heavy roughing jobs, also wet or dry, interrupted or non-interrupted. These new grades also feature the ZrCN top coating and proprietary post-coat treatment that reduces friction and improves edge toughness as well as functioning as an excellent wear indicator.
