Precision hardware refers to hardware products with high precision, high surface quality, high performance and high reliability manufactured through precision machining processes. High Precision: Dimensional accuracy can usually be controlled at the micron level, for example, the diameter tolerance of some precision screws may be within 0.05mm, ensuring precise fit with other components. High Surface Quality: The surface is smooth, flat, and has low roughness, which may reach Ra0.8μm or even lower to meet aesthetic and functional requirements, such as hardware parts in optical instruments. High Performance: It has good mechanical properties, physical properties and chemical properties, such as high strength, high hardness, good electrical conductivity, thermal conductivity, corrosion resistance, etc., like titanium alloy precision hardware used in the aerospace field. Complex shapes and structures: Capable of manufacturing complex-shaped and fine-structured components, such as various cores and cavities in precision molds, as well as miniature connectors in electronic devices.
