Detailed description

Custom CNC Turned Anodized Aluminum Hexagonal Hollow Sleeve

We are a professional CNC precision machining manufacturer located in Dongguan, China. We produce Custom CNC Turned Anodized Aluminum Hexagonal Hollow Sleeves with ultra-precise tolerance up to ±0.01mm, fully manufactured according to customers’ 2D drawings, 3D models and sample requirements. This tubular part features a continuous outer hexagonal profile, straight hollow inner through hole and rounded arc ends, finished with decorative & protective gold anodization. It is widely applied as connecting spacer, positioning pillar, equipment handle sleeve and assembly support tube for precision instruments, automation tooling, electronic devices and optomechanical equipment. We provide full OEM & ODM customized service to satisfy various structural assembly needs for global industrial buyers.

Introduction to CNC Lathe Turning Technology

CNC lathe turning is one of the most precise and efficient manufacturing processes for rotary metal components used in industrial automation and precision machinery. With programmable multi-axis turning centers, solid metal bars are processed through cutting, facing, grooving, boring and threading under computer numerical control.

Compared with manual machining and conventional milling, CNC precision turning ensures stable dimensional tolerance down to ±0.01mm, smooth surface texture and excellent batch consistency during mass production. It is extensively used to fabricate pins, shafts, bushings, sleeves, threaded fittings and various structural hardware for mold accessories, automotive parts, medical devices, electronic equipment and automated production lines.

Equipped with secondary milling functions, CNC lathes are capable of machining stepped surfaces, hexagonal profiles and special-shaped contours, perfectly meeting the diversified production demands of precision positioning structural parts for industrial machinery.

What Is Hexagonal Hollow Sleeve & Its Industrial Functional Value

Hexagonal hollow sleeve is a straight tubular precision machined component with regular hexagon outer surface and hollow inner bore. Its core structural advantages are as follows:

The outer hexagonal outline prevents circumferential rotation during assembly, ensuring stable positioning without slipping; the hollow through hole allows bolts or shafts to pass through for penetration installation; rounded arc ends avoid sharp edge scratches during assembly and usage; anodized aluminum body brings lightweight property, rigid structure and gorgeous decorative appearance.

In automated assembly fixtures, optical testing instruments, medical matching parts and electronic casing assemblies, this hex hollow sleeve serves as key spacing support and connecting component. High concentricity, uniform hexagonal flat size and stable wall thickness are mandatory to guarantee consistent assembly clearance and long-term service life. Custom CNC machined hexagonal hollow sleeves are indispensable standardized customized hardware for precision electromechanical assembly systems.

Custom Service Introduction for Hexagonal Hollow Sleeve

We deliver one-stop CNC machining customization solutions for hexagonal hollow sleeves and all kinds of tubular spacing pillars, cooperating with automation equipment manufacturers, precision instrument enterprises and electronic hardware companies worldwide.

Our customizable product range covers: equal-diameter long hex hollow tubes, short hexagonal spacing sleeves, variable wall thickness hex bushings, colored anodized handle tubes and special-length hollow hexagonal pillars customized for special equipment assembly.

The complete production workflow includes CNC turning, external hexagon milling, inner hole boring, end rounding, deburring and anodizing surface treatment. All processing procedures and surface finishes are strictly executed in accordance with your technical drawings. Apart from single finished sleeves, we can also supply matched fastening accessories to help you realize centralized procurement and simplify on-site assembly work.

Core Advantages of Our Custom Hexagonal Hollow Sleeves

Ultra-high dimensional precision & outstanding concentricity

All sleeves are processed on multi-axis CNC lathes with whole-process dimension monitoring. Inner aperture tolerance, hexagonal opposite-side size, total length and wall thickness are highly unified for each batch product, effectively eliminating assembly jamming, eccentricity and loose positioning issues.

Full flexible structural customization

Based on standard turning and hex milling technology, we support free adjustment of total length, hex width across flats, inner hole diameter, wall thickness and end contour. You can customize anodizing colors, tolerance levels and surface roughness as your assembly requirements, greatly reducing your secondary processing costs and shortening new equipment development cycles.

Lightweight, sturdy structure & superior corrosion resistance

We adopt high-quality 6061/7075 aerospace-grade aluminum alloy as main raw material, featuring high strength and low weight. Optional hard anodizing, sandblasting anodizing and other surface treatments greatly enhance wear resistance, anti-rust performance and surface texture, suitable for long-term cyclic usage in indoor instrument and workshop environments.

Custom non-standard structural design available

We can develop exclusive irregular-length, special wall-thickness hexagonal hollow tubes according to your unique mechanical layout; brand-new non-standard designs are acceptable for your new-generation precision equipment upgrading and iteration.

Stable mass production capacity & on-time delivery guarantee

Whether you need small-batch prototype samples or large-volume bulk orders, we implement unified strict quality inspection standards. Sufficient production equipment and mature processing technology guarantee continuous stable supply, supporting long-term cooperative procurement plans for overseas industrial clients.
