CBN Cutting Conditions of Standard CBN Inserts Machining Sprayed HSS rolls
1. Halnn Tools CBN Cutting Conditions of Standard CBN Inserts Machining Sprayed HSS rolls
Due to the good performance requirements of high-speed steel rolls, the hardness is up to HRC63, which has become a hot-rolling material with rapid development and wide application prospects. At the same time, the requirements for cutting tools are also high. Tool materials for processing high speed steel rolls must have high hardness, wear resistance, heat resistance and impact toughness. Carbide tools and ceramic tools are not recommended.CBN tool is the best choice for processing high speed steel rolls and BN-S20 material is a widely used CBN tool material for processing high speed steel rolls.
