Optical Precision Shaft for Imaging Equipment

Project Overview

A manufacturer of optical imaging systems（Yarui Optics） required precision support shafts used in high-resolution camera modules.

These components required extremely stable concentricity and ultra-smooth surfaces to ensure accurate optical alignment.

Customer Requirements

• Diameter tolerance: ±0.005 mm
• High concentricity control
• Mirror-level surface finish
• Micro chamfered edges

Manufacturing Solution

Using Swiss-type precision turning, our process included:

• Micro finishing tools
• High-precision guide bushing support
• Final polishing and quality inspection

Results

• Surface roughness improved to Ra 0.3 μm
• Excellent concentricity control
• Reduced assembly adjustment time for the customer
