Metal turning machining

stainless steelaluminumaluminum alloy

This precision CNC turned conical metal component is engineered for high accuracy and durability in demanding applications. Made from aluminum alloy or stainless steel, it features a finely machined conical surface and central bore, ensuring excellent alignment, sealing, and assembly performance. The tight tolerance of ±0.01 mm guarantees consistent quality and reliable functionality in machinery, automotive, and fluid system applications. At HLC, we specialize in CNC turning and milling of complex geometries, supported by over 20 years of manufacturing experience. With advanced equipment and IATF 16949 certification, we provide custom solutions that meet international standards, from prototypes to large-scale production. The process begins with material selection, where high-quality aluminum alloy or stainless steel is chosen for its strength, corrosion resistance, and machinability. The raw material is then processed using CNC turning, which precisely forms the conical surface and inner bore. During this stage, fine cutting tools and optimized parameters are applied to achieve the required ±0.01 mm tolerance. For additional features such as grooves or flats, CNC milling may be used in combination with turning. After machining, the parts undergo surface finishing, such as polishing or custom treatments, to enhance appearance, wear resistance, and performance in various operating environments. Finally, each component is subjected to strict quality inspection, including dimensional checks, surface roughness testing, and functional verification. At HLC, we utilize automated inspection systems and follow IATF 16949-certified procedures to ensure every part meets the highest industry standards. - Material: Aluminum alloy / Stainless steel - Surface: Polished / Customized - Tolerance: ±0.01 mm - Application: Machinery, automotive, and fluid systems for guiding, sealing, or precision assembly
