Tungaloy’s PCD Turning Inserts for Improved Chip Control

Tungaloy’s PCD turning inserts now feature a 3D NS chipbreaker which is designed to provide chip control in nonferrous applications for improved productivity.

The inserts were developed to address the issue of long, continuous chips which are generated during the machining of aluminum or copper alloy parts with a conventional PCD insert that has no integrated chipbreaking geometry. These long chips can often cause scratching of the machined surface which can diminish productivity and the resulting surface quality.

The 3D chipbreaker is directly engraved on the PCD tip. This enables the generation of short chips during the machining of gummy metals (such as aluminum and copper alloys), thereby significantly reducing machine downtime due to chip associated troubles.

The chipbreaker is designed to cater to a wide cutting depth range — from extremely light up to 2.0-mm (0.079") DOC. This enables a single PCD insert to handle a variety of operations, from roughing to finishing, giving users the benefit of integrating machining processes and reducing insert inventory for improved productivity.

There are 10 new PCD inserts featuring the chipbreaker in the DX110 grade, providing the insert with a secure edge line for a high-quality, mirror-like surface finish, the company says.
