Precision Turned Bushings and Fitting Assemblies

Please provide 2D/3D drawings specifying dimensions, tolerances, and surface roughness requirements to facilitate process evaluation and quotation for non-standard custom parts. The component collection shown covers various critical forms, from fluid control to mechanical positioning, including pipe fittings with external threads and hexagonal mounting surfaces, precision bushings with multi-stage stepped structures, square support bases with counterbored holes, and smooth pins. These parts typically serve as core connectors in hydraulic/pneumatic systems, automation equipment, or precision instruments, performing functions such as pipeline sealing, bearing support positioning, and mechanism locking.

The manufacturing focus for these rotational and irregularly shaped components lies in ensuring the coaxiality of inner and outer circles, thread precision, and flatness of mating surfaces. For fitting-type parts, strict control over thread profile and sealing surface finish is required to prevent leakage. Square support bases involve multi-process coordination of milling and drilling, requiring assurance of positional accuracy for side mounting holes and perpendicularity for central counterbores. For thin-walled sleeve structures, clamping schemes must be optimized during machining to suppress deformation, ensuring inner hole roundness meets precise tolerance grades such as H7.

Our factory is equipped with CNC lathes, Swiss-type automatic lathes, and machining centers, supporting customized production in various metals including stainless steel, carbon steel, aluminum, and brass. Utilizing high-precision equipment such as Taikan machining centers and Tsugami Swiss-type lathes, we achieve one-shot turn-mill composite forming, effectively reducing cumulative errors caused by secondary clamping. Combined with inspection methods using Keyence dimensional measuring instruments, air gauges, and hardness testers, we perform 100% inspection of key dimensions to ensure consistency in batch delivery. Surface treatments such as electroplating, anodizing, and sandblasting are available based on operating conditions to meet corrosion resistance or aesthetic requirements.
