Recommended for those who: have not been able to find a supplier due to the high precision of the parts.
**Background of Manufacturing** This product faced the challenge of being highly precise and not suitable for mass production due to the large quantity required. While it was possible to produce one unit, there was difficulty in considering suppliers for mass production. **Points of Difficulty** With a thickness of 1mm and geometric tolerances within 5μm, we had to devise methods for removing internal stress and also innovate the chucking process, as the product would distort when gripped. **Product Information** Material: Brass (Gunmetal) Size: Φ62 Precision: Dimensional tolerance range: 10μm Geometric tolerance: Roundness within 5μm, Flatness within 5μm Lot size: Approximately 100 units Industry: Optical equipment industry Processing method: Composite lathe processing with holes on the outer diameter **Selling Points** This product had very strict tolerances among our offerings. Notably, we were able to finish the roundness of a product with a thickness of only about 1mm within 5μm and successfully mass-produce 100 units, which is a significant highlight.
