Detailed description

Custom CNC Turned Multi‑Step Round‑Tip Locating Dowel Pin

Our Custom CNC Turned Multi‑Step Round‑Tip Locating Dowel Pin is a multi‑stage positioning component with smooth rounded tip. As a professional CNC turning manufacturer based in Dongguan, we produce customized multi‑step locating dowel pins with ±0.01mm ultra‑precise tolerance strictly following customers’ 2D & 3D engineering drawings. We support full OEM & ODM customization for step diameter, step quantity, total length and round‑tip dimension. These multi‑step dowel pins are widely adopted for positioning alignment, quick‑fit assembly and limiting installation in automation fixtures, test jigs and precision mechanical equipment.

Introduction to CNC Lathe Turning Technology

NC 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

Multi‑step round‑tip locating dowel pin is a multi‑diameter positioning pin with rounded guiding end. The graded‑step structure realizes multi‑stage positioning, and round tip provides smooth guiding during insertion. It solves common pain points such as difficult insertion, misalignment and unstable positioning for fixture assembly. It improves assembly accuracy and repeat positioning performance for jigs and mechanical modules.

Our Product Service

We provide one‑stop custom CNC turning service for multi‑step round‑tip locating dowel pins for global fixture and precision equipment suppliers. Our product scope covers custom locating pins, dowel pins, stepped shafts and other non‑standard turned hardware. We perform multi‑step turning and round‑tip forming based on customer engineering drawings. Value‑added services include surface treatment, dimension inspection, prototype sampling and large‑batch OEM production.

5 Core Advantages

Multi‑step graded positioning structure

Precision machined multi‑diameter shoulders realize multi‑stage locating, meet complex fixture positioning requirements.

Smooth rounded guiding tip

Well‑formed round tip reduces insertion resistance, protects mating holes during assembly.

High coaxiality for stepped sections

Strict coaxiality control guarantees repeat positioning accuracy for long‑time cyclic operation.

Rich material selection

Stainless steel, brass, aluminum and carbon steel for anti‑corrosion, wear‑resistant or lightweight working scenarios.

Drawing‑oriented full customization

Step quantity, diameter and length can be adjusted; small‑batch prototype and mass orders are both acceptable.

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.
