VMT 2025 07 21 Inconel Alloy machining is the process of cutting or shaping nickel-based superalloys that resist heat, corrosion, and pressure. Due to its high work hardening rate and toughness, Inconel requires specialized CNC machining tools, optimized speeds, and coolants. Machining Inconel successfully demands experience, precision, and the right equipment from a qualified CNC machining factory.

VMT 2025 07 15 Composite materials differ from traditional metal materials in CNC machining due to their structure, machinability, and performance characteristics. While metals offer high strength and thermal stability, composites provide lightweight properties, corrosion resistance, and customizability. Each material affects cutting techniques, tool wear, surface finish, and production cost — making material selection crucial for optimized CNC machining parts.

VMT 2025 07 14 2Cr13 and 3Cr13 are both martensitic stainless steels. The main difference lies in carbon content: 3Cr13 has higher carbon (≈0.3%) than 2Cr13 (≈0.2%), making it harder and more wear-resistant but slightly less corrosion-resistant. 2Cr13 is better for general machining; 3Cr13 suits tools requiring edge retention.
