Detailed description

Custom CNC Turned Brass Bushing Sleeve

Our custom CNC Turned Brass Bushing Sleeve is a cylindrical wear-resistant bearing component made of brass material. As a professional CNC turning manufacturer based in Dongguan, we produce customized brass bushing sleeves with ±0.01mm ultra-precise tolerance strictly according to customers’ 2D & 3D engineering drawings. We support full OEM & ODM customization for outer diameter, overall length, inner bore size and step profile. Featuring excellent self-lubricating property, low friction and good wear resistance, this brass bushing sleeve is widely used as sliding bearing and guide part in automation machinery, testing equipment and precision mechanical assemblies.

Introduction to CNC Lathe Turning Technology

CNC lathe turning is one of the most precise and efficient manufacturing methods for rotational metal components used in industrial automation and precision equipment. Using programmable multi-axis turning centers, solid metal bars are shaped through continuous cutting, facing, grooving, threading and boring operations with computer-controlled accuracy.
Compared with manual machining and traditional milling, precision CNC turning delivers consistent dimensional tolerances down to ±0.01mm, smooth surface finishes and excellent repeatability across high-volume production runs. It is widely used to produce pins, shafts, bushings, connectors and threaded components for mold tooling, electronic devices, medical equipment, automotive systems and industrial automation machinery.
With advanced multi-axis turning capabilities paired with secondary milling support, CNC lathe technology enables custom geometries including stepped diameters, ball ends, hexagonal profiles and precision slots, which perfectly meet diversified requirements for precision positioning components in industrial equipment.

What Is Brass Bushing Sleeve & Its Industrial Role

Brass bushing sleeve is a tubular sliding bearing machined from brass. Brass material possesses inherent self-lubricating performance, effectively reducing friction during reciprocating or rotary movement. The stepped outer structure enables reliable positioning and installation inside equipment housings.
In precision mechanical systems, brass bushing sleeves serve as guide sleeves and sliding bearings to support rotating and moving shafts. They lower operation noise, mitigate shaft abrasion and extend service life of moving assemblies. Therefore, custom CNC turned brass bushing sleeve is an essential wear-resistant component for low-speed friction mechanisms.

Custom Brass Bushing Sleeve Service Introduction

We provide one-stop custom CNC turning solutions for brass bushing sleeves and various wear-resistant mechanical hardware, serving automation equipment manufacturers, instrument factories and engineering enterprises worldwide.
Our product portfolio covers multiple tubular bearing parts: brass bushing sleeve, cylindrical guide bushing, wear-resistant bearing ferrule, positioning sleeve and other non-standard machined bushings.
All products are manufactured through integrated CNC turning, internal boring, step forming, chamfering and deburring processes. All machining standards and surface treatments are implemented strictly in accordance with your engineering drawings. Besides individual finished bushings, we can supply matched supporting parts to simplify your assembly and material management.

Key Advantages of Our CNC Turned Brass Bushing Sleeve

Excellent self-lubricating and wear-resistant performance

Adopting premium brass raw material, the bushing sleeve achieves low friction coefficient, suitable for continuous sliding operation without frequent oil maintenance.

Ultra-precise dimension and stable concentricity

All brass bushings are processed on multi-axis CNC turning equipment with full-process dimension monitoring. Tight control of roundness and cylindricity ensures smooth shaft movement.

Flexible personalized structural customization service

Supported by turning and boring processes, we accept customized outer diameter, length, inner hole dimension and step structure. We optimize structural parameters according to your motion requirements to reduce secondary processing.

Rich material and surface treatment options

We supply multiple brass grades as well as aluminum alloy and stainless steel alternatives. Anti-tarnish surface treatment options prevent brass oxidation and improve appearance stability.

Stable mass production and on-time delivery guarantee

From small-batch prototype trial production to large-volume mass orders, we adopt unified strict inspection standards. Mature production technology ensures stable batch consistency and supports long-term bulk procurement for global clients.

Frequently Asked Questions

FAQ 1

Q: Can you produce custom CNC turned parts according to my drawings or samples?
A: Yes, we mainly focus on OEM & ODM customized precision turning services. We accept 2D files like PDF/DWG and 3D files such as STEP, IGES. You can also send physical samples for us to reverse-engineer and optimize the structure. Our engineering team will review your design and offer professional suggestions on cost saving and manufacturability (DFM) for free.

FAQ 2

Q: What kinds of metal materials can you use for CNC turning processing?
A: We support a full range of common precision machining metals, including SUS304/SUS316 stainless steel, 1018/1045 carbon steel, 6061/7075 aluminum alloy, C36000 brass, copper and titanium. We can select suitable raw materials based on your product usage, working environment, strength requirements and budget.

FAQ 3

Q: Can I get trial samples before mass production? How long is the sample lead time?
A: Trial samples are available for all customized turning orders. The sample production cycle is 3–7 working days after drawing confirmation. After you test and confirm the sample quality and dimensions, we will arrange mass production. Small batch trial orders are also acceptable if you do not need large volume at first.

FAQ 4

Q: What surface finishing options do you provide for CNC turned metal parts?
A: We offer multiple surface treatments to meet anti-rust, anti-corrosion, wear resistance and appearance demands: passivation, electropolishing, zinc plating, nickel plating, black oxide, powder coating, anodizing for aluminum, sandblasting and polishing. If your products are exported to Europe, we can provide surface treatment that complies with RoHS and REACH standards.

FAQ 5

Q: How do you control the dimensional tolerance of precision CNC turned parts?
A: Our standard tolerance for general turned parts is ±0.01mm, and ultra-precision components can achieve ±0.005mm with grinding processes. We carry out strict three-step quality inspection: IQC for raw material incoming check, IPQC for in-process production monitoring, and FQC full dimension testing before shipment. We provide inspection reports and accept third-party quality inspection as requested.
