Custom CNC Threaded Shafts | Hongsinn Precision

Custom Precision CNC-Machined Threaded Shafts and Screw Components

Product Overview

A custom precision CNC-machined threaded shaft is a mechanical component consisting of smooth (plain) shaft sections, externally threaded sections, and end-connection features. These parts can be manufactured to specific lengths, diameters, thread specifications, and structural configurations based on customer engineering drawings.

Shenzhen Hongsinn Precision specializes in the OEM/ODM manufacturing of precision, non-standard components. Utilizing 2D engineering drawings, 3D CAD models, or qualified samples provided by the client, we evaluate the optimal manufacturing processes—such as CNC turning, thread machining, and milling—to deliver comprehensive solutions ranging from prototype development and small-batch pilot runs to full-scale mass production.

For components featuring long-shaft geometries, multiple threaded sections, precision-fit smooth segments, or specialized end-positioning features, we ensure strict control over critical parameters—including shaft diameter, length, thread dimensions, coaxiality, straightness, and surface quality—to meet your specific functional requirements.

Technical Specifications

Product Features

1. Segmented Thread Structure

Supports the machining of single or multi-section external threads based on engineering drawings. Thread length, pitch, profile, and tolerances can be customized to meet specific connection and assembly requirements.

2. Precision CNC Turning

Utilizes CNC turning processes to machine the outer diameter, steps, ends, and other rotational features of the shaft. Critical dimensions are controlled according to the tolerances specified by the client.

3. Combined Plain Shaft and Threaded Design

The product can feature a combination of plain (unthreaded) and threaded sections, making it suitable for components that require axial positioning, mechanical fastening, or specific assembly configurations.

4. Customized End Features

End-side features—such as steps, flats, locating slots, holes, and other connection interfaces—can be machined according to engineering drawings. The specific design, machining method, and dimensions are determined by the client-approved drawings.

5. Material and Surface Treatment Options

Suitable materials—including various steels, stainless steels, or other machinable alloys—can be selected based on the operating environment and mechanical performance requirements. Surface treatments can be applied according to the material, corrosion resistance needs, and fit specifications.

Scope of Application

1. Automation Equipment

Can be designed and manufactured for use in automation equipment as connecting shafts, positioning shafts, mounting shafts, or other custom threaded mechanical components.

2. Mechanical Transmission and Connection Mechanisms

Suitable for mechanical structures requiring threaded connections, axial fixation, or specific assembly configurations. If the product is intended for motion transmission, factors such as thread type, load, speed, and lubrication conditions must be verified.

3. Industrial Equipment and Specialized Machinery

Can be produced based on specific technical drawings for use as shaft components in industrial equipment, specialized machinery, and custom assembly mechanisms, meeting precise requirements for length, shaft diameter, and connection interfaces.

4. Tooling, Fixtures, and Positioning Mechanisms

Can be designed for use in jigs, fixtures, positioning mechanisms, and equipment mounting structures, providing specific threaded connections, axial positioning, and structural mating functions.

5. OEM/ODM Custom Component Projects

Suitable for mechanical equipment manufacturers, automation firms, industrial system integrators, and purchasers of precision parts—covering needs ranging from custom development and prototype fabrication to mass production.
