728x90 SMALL toughness1 Requirements for Cutting Tool Materials 1. High-temperature hardness Cutting tools are exposed to high temperatures during machining, so they must maintain their hardness at high temperatures. Materials with low high-temperature hardness will wear more easily during machining, shortening the tool life. 2. Toughness Cutting tools are exposed to shock and vibration during machining, so they must be tough. Materials with low toughness ca.. 2024. 1. 25. 이전 1 다음 728x90
