Automotive – Bearing Housing

Turbocharger Bearing Housing

Bearing housing (center housing) is located between the compressor and turbine to house a bearing system that supports the turbine-compressor common shaft. The bearing housing is commonly cast from gray cast iron, but aluminum can also be used in some applications. As customer increases production outputs, Process Improvement pressure intensifies on cutting tool suppliers as well, urging the delivery of improved process efficiency and security. Tungaloy meets these challenges with continued effort in heightening milling, turning, grooving, and hole making, all application capabilities, as well as through the development of combination tools for process integration.

General Challenges

  • To maximize process security and efficiency for high-volume production needs
  • To provide optimal tools and solutions that improve efficiency for cast iron machining requiring large, uneven stock removal
  • To maximize machine uptime and minimize downtime

Key Points

  • Increased tool life and predictability for process security

  1. T515 is a versatile CVD-coated carbide grade developed specifically for ISO-K cast iron. A thick TiCN+Al2O3 layer combined with a dedicated carbide substrate provides the grade with a great balance of wear resistance and toughness during machining at increased cutting parameters. In addition, the top layer surface is post-treated with PremiumTec technology, enhancing its surface smoothness that resists chipping and welding, while improving surface finishing quality.
