Detailed description

Custom CNC Turned Stepped Shaf With Side Threaded Hole

Our Custom CNC Turned Stepped Shaft With Side Threaded Hole is a precision composite machined component featuring flat mounting head, transverse internal threaded bore and multi-step shaft body. As a professional CNC turning manufacturer based in Dongguan, we produce customized stepped shafts with ±0.01mm ultra-precise tolerance strictly following customers’ 2D & 3D engineering drawings. We support full OEM & ODM customization for shaft diameter, step dimension, thread specification and flat head size. These side-threaded stepped shafts are widely used for linkage connection, positioning assembly and mounting fitting in automation fixtures, testing jigs and precision mechanical equipment.

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, metal bars are processed through continuous cutting, facing, grooving, threading and boring with computer‑controlled accuracy.
Compared with manual machining and conventional milling, precision CNC turning achieves stable dimensional tolerance down to ±0.01mm, smooth surface quality and outstanding consistency during mass production. It is widely applied to fabricate pins, shafts, bushings, connectors and threaded parts for mold, electronics, medical, automotive and automation machinery.
Equipped with secondary milling and cutting capacity, CNC turning supports complex customized profiles including stepped cylinders, grooved structures and multi‑sided profiles, satisfying diversified precision positioning component demands for industrial equipment.

Product Definition & Industrial Value

Stepped shaft with side threaded hole is a composite structural fitting composed of flat positioning head, transverse internal threaded hole and multi-diameter stepped shaft body. The flat head prevents rotation after installation, the side threaded hole provides reliable threaded connection interface, and the stepped shaft body realizes accurate positioning and multi-section assembly matching. It solves common industry pain points such as difficult positioning during assembly, loose connection under vibration and poor geometric position accuracy, effectively improving connection reliability and transmission positioning precision for mechanical linkage and fixture assembly systems.

Our Product Service

We provide one-stop custom CNC turning-milling composite service for side-threaded stepped shafts for global automation equipment and machinery manufacturers. Our product scope covers custom stepped connecting shafts, positioning pins, linkage fittings and other non-standard composite machined hardware. We complete full turning, flat end milling, side thread tapping and surface finishing strictly based on customer engineering drawings. Value-added services include diversified surface treatment, full-dimension inspection, prototype sampling and large-batch OEM production.

5 Core Advantages

Integrated turning-milling one-clamp machining

The flat head, stepped shaft body and side threaded hole are machined in one clamping through composite turning-milling process, which eliminates secondary clamping error, ensures strict perpendicularity between threaded hole and shaft axis, and guarantees high-precision geometric position tolerance.

Anti-rotation flat head + side threaded connection structure

The flat mounting head effectively prevents circumferential rotation after assembly, and the transverse internal threaded hole provides stable threaded locking interface. The combined structure avoids loosening and displacement under long-term vibration and frequent movement, ensuring stable operation of linkage mechanism.

High coaxiality multi-step shaft design

Each diameter section of the stepped shaft is machined continuously, with excellent coaxiality control and dimensional tolerance up to ±0.01mm. It realizes precise positioning and smooth assembly matching, suitable for precision transmission and positioning assembly scenarios.

Wide material adaptation for diverse working conditions

Optional materials include stainless steel, aluminum alloy, brass and carbon steel, which can meet different requirements of corrosion resistance, weight and strength, and adapt to various industrial application scenarios from ordinary machinery to precision instruments.

Full-parameter drawing-based customization

All key parameters including shaft diameter, step length, thread standard and flat head size can be fully adjusted according to your 2D/3D drawings or physical samples. We accept both small-batch prototype verification orders for new product development and large-volume mass production orders for formal projects.

OEM Custom Service Range

We provide comprehensive customized solutions for custom stepped shafts with side threaded hole and all kinds of precision CNC turned components. Available materials include SUS304/SUS316 stainless steel, 6061‑T6 aluminum alloy, C36000 brass and carbon steel, with sufficient bar stock to match different strength, corrosion resistance and weight requirements.
Our custom product range includes connecting shafts, locating pins, bushings, threaded fittings and other rotational precision machined parts. Selectable surface treatments: natural machined finish, passivation, nickel plating, zinc plating, black anodizing and polishing.
We can supply single parts or matched hardware kits according to assembly needs. Custom machining will be developed based on your drawings or samples. Small batch prototype testing is available before formal mass production.

Typical Application Scenarios

Our Custom CNC Turned Stepped Shaft With Side Threaded Hole is widely used in mechanical linkage mechanism assembly, automation fixture mounting, testing equipment connection fitting, mold positioning accessories, equipment transmission components and industrial hardware connection assembly.

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.
