CNC Machining Precision Mini Shaft for Automotive & 3C

High Precision Mini Shaft for Automotive and 3C Applications

1. Material: Made of high-quality stainless steel or alloy steel, etc.

2. Shape: A small, stepped shaft structure, including a positioning end, transition section, and bottom flange.

3. Size Range: Diameter: Φ1mm – Φ5mm; Height: 5mm – 20mm (customizable).

4. Internal Design: Solid structure design ensures good load-bearing capacity and deformation resistance; partial chamfering and rounded corners effectively reduce stress concentration and improve service life.

5. Surface Treatment: Precision polishing for a high gloss finish; optional electroplating and passivation processes enhance corrosion resistance and appearance while reducing friction loss.

6. Manufacturing Process: Advanced CNC precision machining technology, one-piece molding, ensuring strict dimensional tolerance control and excellent concentricity.

Advanced CNC Precision Machining & One-Piece Molding

Our engineered mini shaft for automotive and electronic devices is manufactured utilizing state-of-the-art multi-axis CNC Swiss-turning technology. This advanced one-piece molding process eliminates structural weak points, ensuring strict dimensional tolerance control and excellent concentricity that meets the rigorous performance bars of international supply chains.

Optimized Stepped Design & Micro Dimensions

Caiyi provides full-dimensional customization to match your precise engineering prints. The standard technical envelope includes:

Micro Dimensions: Diameter from Φ1mm – Φ5mm; Height: 5mm – 20mm (fully customizable).
Geometric Architecture: A complex, small stepped shaft structure integrating a positioning end, a transition section, and a structural bottom flange.
Stress Reduction: Integrated partial chamfering and rounded corners effectively minimize stress concentration, dramatically boosting fatigue resistance and extending service life.

Premium Materials & Heavy Load-Bearing Capacity

We use only certified, high-grade stainless steel or alloy steel to guarantee structural integrity. The solid internal design provides exceptional load-bearing capacity and deformation resistance under constant mechanical stress, making it reliable for high-frequency micro-actuators, automotive instruments, and 3C hardware.

High-Spec Surface Treatments for Enhanced Durability

To minimize friction and withstand harsh operating environments, each micro shaft undergoes premium post-processing:

Precision Polishing: Delivers a high-gloss finish, reducing tribological wear and friction loss.
Passivation & Electroplating: Optional anti-corrosion chemical treatments that protect the component from oxidation and chemical wear, ensuring premium appearance and performance over time.
