Detailed description

Custom CNC Turned Stepped Solid Dowel Pin

Our Custom CNC Turned Stepped Solid Dowel Pin is a one-piece solid precision locating component with multi-diameter stepped structure. As a professional CNC turning manufacturer located in Dongguan, we fabricate non-standard stepped solid dowel pins with ±0.01mm ultra-precise tolerance strictly based on customers’ 2D & 3D engineering drawings. We support full OEM customization for diameter, length and step layout. These solid stepped dowel pins are widely adopted for alignment, positioning and assembly locking in automation fixtures, mould equipment, electronic machinery and precision testing devices.

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 and secondary machining support, CNC turning supports custom geometries including stepped diameters, flanges, internal threads and precision grooves, which perfectly meets the diversified demands of precision locating components for industrial equipment.

Product Definition & Industrial Value

Stepped Solid Dowel Pin is a solid cylindrical locating pin designed with multiple diameter segments. Different diameter sections achieve two-way positioning and limit assembly displacement, solving positioning deviation issues of ordinary straight dowel pins.

In automated fixtures, mold assemblies and precision mechanical equipment, accurate coaxiality and stable dimensional consistency of stepped solid dowel pins guarantee assembly repeatability. High precision custom stepped solid dowel pins become essential hardware to ensure long-term stable operation of precision equipment.

Custom Service Introduction

We provide one-stop CNC turning customization service for stepped solid dowel pins and various precision locating pins for global equipment manufacturers.

Our product range covers stepped solid dowel pins, alignment pins, shoulder pins, straight dowel pins and other non-standard CNC turned locating components.

All pins are integrally machined by precision CNC lathes. All dimensions, material choices and surface finishes can be customized according to your engineering drawings. We support separate supply of single locating pins or matched component sets to simplify your procurement process.

5 Core Advantages

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.
