Detailed description

Custom CNC Turned Multi-Step Brass Locating Pin

Our Custom CNC Turned Multi-Step Brass Locating Pin is a multi-stage stepped positioning component with tapered tip. As a professional precision CNC machining manufacturer in Dongguan, we produce brass locating pins with accuracy up to ±0.01mm, fully customizable based on engineering drawings or samples. Good conductivity and self-lubricating property make brass an ideal choice for testing jigs and electrical fixtures. The multi-step structure realizes quick positioning and depth limiting. It is widely adopted for alignment, positioning and limiting in automation tooling, testing equipment, electronic assembly and precision mold 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, 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.

What Is Multi-Step Brass Locating Pin & Its Industrial Function

Multi-step brass locating pin is a stepped cylindrical positioning part with multiple diameter sections and a tapered guide tip. Different diameter steps act as depth limit and stop surface during assembly. The tapered front end guides smooth insertion into matching holes to avoid jamming.
Brass material offers excellent machinability, moderate hardness and natural anti-rust performance. Mainly used for alignment, positioning and limiting displacement between workpieces in fixtures, jigs and automated production lines. It ensures repeatable assembly accuracy for batch production testing and processing.

Custom CNC Turned Multi-Step Brass Locating Pin

We supply one-stop custom CNC turning solutions for multi-step brass locating pins, serving automation equipment manufacturers, electronic testing factories and mold processing clients worldwide.
Our precision pin product range covers stepped locating pins, straight dowel pins, tapered positioning pins, probe pins and other non-standard custom machined locating components.
All workpieces are manufactured by multi-axis CNC lathe turning, step forming, taper machining and fine deburring. We strictly follow your 2D/3D drawing requirements. We can also develop matched positioning sleeves and auxiliary components to complete your fixture assembly solutions.

Key Advantages of Our CNC Turned Multi-Step Brass Locating Pin

Multi-step integrated forming design

Different diameter sections realize positioning and depth limiting at the same time, simplify fixture structure and reduce assembly parts count.

Taper guiding tip

Optimized tapered front end enables easy insertion, effectively prevents scratching mating holes and improves assembly smoothness.

High concentricity precision

Strictly controlled concentricity between each step, guarantee stable repeated positioning accuracy for long-term continuous use.

Superior brass material performance

Brass features good machinability, low friction and corrosion resistance, suitable for electrical testing and light-load fixture scenarios.

Flexible customization & order support

All dimensions, step layout and tip shape can be customized. We accept small batch prototype sampling and large-volume mass production.

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.
