Custom CNC Machined Flanged Sleeve and Flanged Bushing with Dual-Flange Connection Structure, Precision Internal Bore and Shoulder Machining, and Versatile Threaded Hole Placement

Hongsinn Precision offers custom CNC machining services for precision flanged sleeves, flanged bushings, and non-standard metal connectors. The product shown features an integrated design—a long cylindrical body combined with upper and lower flanges—incorporating a central through-hole, end-face steps, circumferential mounting holes, and lateral threaded holes. These components can be custom-machined to meet the specific structural and assembly requirements of a client's equipment.

These CNC precision flanged sleeves are suitable for applications such as connecting mechanical components, structural positioning, shaft-sleeve support, and the installation of specialized equipment. Utilizing processes including CNC turning, CNC milling, drilling, boring, and tapping, we can machine internal and external cylindrical surfaces, end faces, flange holes, and lateral threaded holes to satisfy the dimensional and assembly specifications of complex structural parts.

Shenzhen Hongsinn Precision specializes in the manufacturing of precision, non-standard components. We provide OEM/ODM services to global clients—ranging from prototype development and small-batch trial production to full-scale mass production—and can manufacture parts based on 2D engineering drawings, 3D CAD models, or physical samples.

• Dual-Flange Connection Structure The upper and lower flanges can be customized with specific external dimensions, mounting hole layouts, and connection configurations to suit mechanical structures that require fixation or positioning at both ends.
• Precision Internal Bore and Shoulder Machining The central through-hole and annular shoulders on the end faces can be machined according to technical drawings, making the component ideal for assemblies with specific shaft diameters, locating shoulders, or precise fit requirements.
• Versatile Threaded Hole Placement Radial threaded holes can be machined into the cylindrical side surface for screw-based fixation, auxiliary positioning, or the attachment of other structural components. Thread specifications, hole depths, and orientations can be tailored to specific design requirements.
• CNC Turn-Mill Composite Machining Depending on the part's geometry, processes such as CNC turning, milling, drilling, boring, and tapping can be combined to achieve complex features. Machining datums are strategically planned to ensure precise control over critical dimensions and the spatial relationships between holes.
• Wide Range of Metal Materials Materials—including aluminum alloys, stainless steel, carbon steel, and alloy steels—can be selected based on requirements for strength, weight, corrosion resistance, and the intended operating environment.

• Industrial Automation Equipment: Custom metal structural components can be designed for use as mounting brackets, connecting sleeves, positioning assemblies, or parts of automated mechanisms.
• Precision Machinery: Suitable for mechanical components that require a central through-hole, flanged ends, and lateral fixation; these can serve as positioning, supporting, or connecting elements.
• Power Transmission and Shaft System Auxiliary Components: Depending on the structural design and dimensional fit, these parts can function as support sleeves, mounting sleeves, or connecting components within or around shaft systems. Specific applications should be determined based on actual technical drawings.
• Specialized Industrial Equipment: Applicable to specialized machinery and non-standard assembly mechanisms that require specific lengths, flange hole patterns, central bore diameters, or radial threaded holes.
• OEM Precision Component Procurement: Ideal for equipment manufacturers, mechanical engineering firms, and industrial component purchasers seeking custom development; services include prototype fabrication, product validation, and subsequent batch production.
