Proven Solution: Precision Internal Turning Solution for the Defense Industry

A renowned manufacturer of defense, aerospace, medical and industrial components faced a significant challenge in the precision internal turning of a small component. The primary issues were maintaining high surface quality and effective chip control. With the help of the Kennametal team, here’s how the customer overcame these challenges and achieved significant improvements in their manufacturing process.

The customer's existing turning solutions were not meeting the desired standards, prompting the search for a better alternative. The material used for the component was MP35N (R30035), a nickel-cobalt superalloy known for its toughness and resistance to corrosion, making it an extremely challenging material to work with

Kennametal collaborated with the client and their local distribution representative to identify and implement a more effective solution. The decision was to use a TopSwiss™ MBS insert in grade KCSM25S along with a high-performance tool holder . This combination allowed them to significantly increase the depth of cut by 66%, from 0.005” to 0.015”.

The implementation of the TopSwiss MBS insert and high-performance tool holder yielded exciting outcomes:

• The depth of cut was increased by 66%, enhancing the efficiency of the turning process
• The tool life was extended from 375 pieces to 740 pieces, an increase of 97%
• Despite the increased depth of cut and tool life, the surface quality remained high and met the rigorous standards of the defense industry application.

Kennametal and the distributor successfully addressed the client's challenges, which required precision internal turning of the component. By increasing both the metal removal rate (MRR) and tool life, they not only outperformed their competitor but also maintained high surface quality.
