Diamond saw blade substrates primarily use medium-to-high carbon spring steel. Non-metallic inclusions, uneven microstructure, micro-cracks, and surface defects in these steels can become potential sources of fatigue cracks, leading to premature substrate failure. 1. Material Factors Affecting Crack Formation 1.1 Non-Metallic Inclusions Non-metallic inclusions such as Al₂O₃ and TiN are produced during the steelmaking process….

Diamond cutting tools are widely used in precision machining of non-metallic hard and brittle materials such as graphite, high-wear materials, composites, high-silicon aluminum alloys, and tough non-ferrous metals. Diamond tools offer extremely high hardness and wear resistance, low friction coefficient, high elastic modulus, high thermal conductivity, low thermal expansion coefficient, and low affinity with non-ferrous…
