Detailed description

Custom CNC Turned Multi‑Step Locating Pin

Our Custom CNC Turned Multi‑Step Locating Pin is a precision positioning hardware component with multi‑step shoulder structure and smooth ball‑tip end. As a professional CNC turning manufacturer based in Dongguan, we produce customized multi‑step locating pins with ±0.01mm ultra‑precise tolerance strictly following customers’ 2D & 3D engineering drawings. We support full OEM & ODM customization for step dimension, total length and ball‑tip radius. These multi‑step locating pins are widely adopted for positioning alignment, guiding insertion and fixture locating in automation jigs, mold units 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

Multi‑step locating pin is an integrated positioning part with multiple diameter shoulders and rounded ball tip. Different step diameters realize segmented positioning, and smooth ball‑tip greatly facilitates guided insertion during assembly. It effectively solves common industry pain points including difficult insertion, poor repeat positioning accuracy and unstable stop‑limiting effect, improving assembly efficiency and positioning stability for jigs, molds and automation modules.

Our Product Service

We deliver one‑stop custom CNC turning service for multi‑step locating pins for global fixture and mold equipment suppliers. Our product scope covers custom stepped locating pins, ball‑end positioning pins, non‑standard dowel pins and other turned precision hardware. We complete full turning, ball‑tip forming and multi‑shoulder machining strictly based on customer engineering drawings. Value‑added services include surface treatment, full‑dimension inspection, prototype sampling and large‑batch OEM production.

5 Core Advantages

Multi‑step shoulder positioning structure

Integrated multi‑diameter shoulder design realizes segmented limit and multi‑stage positioning within one single part. It avoids assembling multiple separate locating pins, reduces cumulative assembly tolerance errors, simplifies fixture layout and makes mechanical structure more compact for limited installation space.

Smooth ball‑tip guiding end

Precision‑machined rounded ball tip provides smooth guiding performance during insertion operation. It reduces scratch risk for mating holes, lowers assembly resistance, enables smooth plug‑in even for slight misalignment, and greatly improves operating efficiency for repeated fixture loading cycles.

Excellent inter‑section coaxiality

Strict coaxiality control among every stepped segment and ball tip. Each diameter section maintains good concentricity, so the locating pin will not tilt or offset after installation, ensuring high repeat positioning accuracy for long‑term cyclic working of automation jigs and mold assemblies.

Flexible material options for diverse working conditions

Multiple raw material selections including stainless steel, brass, aluminum alloy and carbon steel. Customers can select proper material for high hardness, wear‑resistance, corrosion resistance or lightweight requirements to adapt to various complex industrial application environments.

Drawing‑driven full customization capability

All critical parameters including each‑step diameter, shaft overall length, ball‑tip radius and base dimension can be fully adjusted according to your 2D/3D drawings or physical samples. We accept both small‑batch prototype verification orders and large‑volume mass manufacturing projects.

OEM Custom Service Range

We provide comprehensive customized solutions for custom multi‑step locating pins and all kinds of precision CNC turned components. Available materials include SUS304/SUS316 stainless steel, 420 stainless steel, C36000 brass, 6061 aluminum alloy and carbon steel, with sufficient bar stock to match different strength, conductivity and corrosion resistance requirements.
Our custom product range includes locating pins, bushings, stepped shafts, threaded fittings and other rotational precision machined parts. Selectable surface treatments: natural machined finish, passivation, nickel plating, zinc plating and hardening treatment.
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 Multi‑Step Locating Pin is widely used in automation fixture positioning, test jig assembly, mold locating unit, mechanical guiding assembly, equipment limit positioning and industrial precision machinery 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.
