Steel Machining with CA5 Series CVD-Coated Grades

Introducing the newly completed CA5 series of CVD-coated grades for steel. In addition to CA515 and CA525 for long tool life and stable steel machining, CA510 is now available for high-speed machining, and CA530 for heavy interrupted and high-feed machining completes the new lineup.

Let’s take a closer look at the key advantages of the CA5 series. First is high coating-film adhesion. Interface strength has improved by 40% over the conventional grade. Second, high hardness and toughness in the alpha-aluminum-oxide layer provide longer tool life. Third, a smooth, uniform surface generates low cutting forces and prevents chip welding, which can lead to fracturing. Fourth is a new carbide substrate with improved deformation resistance at high temperatures. This allows high-efficiency machining with 10% improved high-temperature hardness. Finally, the completion of the series of PG, PP, and PQ chipbreakers.

The PG chipbreaker is for medium and rough machining. It is a solution for chip compacting and improves chip control during low- and high-feed machining. It also controls crater wear through a twin-dot structure. In this case study, CA525 and the PG chipbreaker provided longer tool life than a competitor product.

The PP chipbreaker for finishing prevents chip compacting and tangling at small depths of cut with increased feed rates. The PQ chipbreaker for finishing and medium machining reduces chip compacting and cutting force. These three chipbreakers create an effective combination to cover a broad range of steel machining applications. Give the CA5 series an opportunity to advance your productivity.
