Precision machining is the core engine of high-end manufacturing. From chip molds to aerospace components, every breakthrough in micron-level precision relies on the ultimate support of material properties. Under the demanding conditions of high-speed cutting and ultra-precision grinding, high-performance specialty steels, with their exceptional hardness, toughness, and stability, become the "foundation of precision carving" in precision manufacturing, fundamentally determining the quality, accuracy, and performance ceiling of high-end products.

From mold manufacturing to core component processing, steel is used throughout the entire precision machining landscape. In the semiconductor chip mold industry, pre-hardened plastic mold steel, through precise composition control and heat treatment, maintains a stable hardness between 30 and 45 HRC, enabling machining accuracy of 0.001mm and ensuring consistent chip packaging. In the machining of aircraft engine turbine blades, high-speed tool steel, with a bending strength exceeding 1200 MPa and a hardness of 60 HRC, can withstand cutting speeds of tens of thousands of revolutions per minute, enabling the precise shaping of complex curved surfaces. The application of these specialty steels not only breaks through technical bottlenecks in precision machining but also propels manufacturing precision toward the nanometer level.

With the advancement of high-end manufacturing, steel technology is moving toward a new dimension of "customization + multifunctionality." Ultrafine-grained steel produced through powder metallurgy technology improves uniformity by 40%, extending the fatigue life of precision parts by more than two times. Self-lubricating composite-coated steel reduces friction loss during cutting, increasing machining efficiency by 30%. Key breakthroughs have been achieved in domestic precision machining steel, from 718H pre-hardened steel used in Huawei mobile phone molds to GCr15SiMn bearing steel used in high-speed rail bearings. This has achieved independent control over core materials, laying a solid foundation for the localization of high-end manufacturing.

In the future, with the deep integration of intelligent machining and green steel, the precision machining sector will achieve the coordinated development of "high precision, high efficiency, and low energy consumption." "Smart steel," with real-time performance feedback, can dynamically adapt machining parameters, continuously creating a more precise and reliable "manufacturing foundation" for the high-end manufacturing industry.
