The Newly Developed CBN Cutting Tool

  • Chapter
Proceedings of the Twenty-First International Machine Tool Design and Research Conference

Abstract

The newly developed cutting tool, Sumiboron BN200, is made of a special ceramic which is heat resistant, wear resistant and has a lower affinity for a workpiece material. The following experimental results were obtained:

  1. 1)

    Grains of BN200 showed attritious wear in a wide range of cutting conditions.

  2. 2)

    The bonding material of BN 200 was removed to such an extent by formed chips that grains were projected. Abrasive wear was partly observed.

  3. 3)

    In dry cutting of ASTM4118 and wet cutting of ASTM 5046, the tool life of BN200 was found to be increased by respectively 3~5.7 times that of a conventional CBN cutting tool.
