Precision CNC Turned Cylindrical Handle

Serving as a support and connecting bushing in automation equipment or precision instruments, this cylindrical structure features radial holes on the sidewall for pin fixation or fluid guidance. This rotational part, characterized by a high length-to-diameter ratio, is commonly used as a positioning component in mechanical transmission systems, a guide rod for pneumatic actuators, or a decorative housing. Its surface exhibits a refined finish, combining metal strength with excellent corrosion-resistant aesthetics.

The manufacturing process strictly controls the straightness of slender shaft parts and the perpendicularity between the end faces and the outer circle to prevent wobble or jamming during assembly. The sidewall drilling process ensures high precision in circumferential hole distribution and thorough deburring to avoid sharp edges that could damage mating parts or injure operators. For aluminum alloy substrates, cutting parameters are optimized to suppress deformation. Additionally, high-precision anodizing imparts a uniform matte texture, enhancing wear resistance and meeting the strict appearance consistency requirements of high-end equipment.

Equipped with multiple high-precision CNC lathes and Coordinate Measuring Machines (CMM), we strictly control central bore diameter, outer diameter tolerances, and geometric errors to ensure dimensional stability for batch deliveries. We support non-standard customization based on customer-provided 2D/3D drawings, accommodating various lengths, diameters, and surface treatment colors. Adhering to the ISO 9001 quality management system, our production process includes material traceability, go/no-go gauge inspection, and 100% visual inspection. We provide material certificates and test reports, meeting the customized needs for lightweight metal structural components in industries such as medical devices, semiconductor equipment, and consumer electronics.
