Fiber Optic Polishing Machine: An Efficient Solution Supporting Custom Fixtures and a Variety of Polishing Film Granular

In the fiber optic communications industry, the processing and polishing quality of optical fiber end faces directly impacts signal transmission stability and loss reduction. As core equipment, the Fiber Optic Polishing Machine (Fiber Optic Polishing Machine) is responsible for polishing optical fiber connector end faces to a smooth, scratch-free, and low-loss finish. As fiber optic applications continue to expand, users have varying process requirements and mass production demands, making equipment flexibility and customizability particularly important. This article will focus on the advantages of the Fiber Optic Polishing Machine in supporting custom fixtures and offering a variety of polishing film grit sizes, helping companies achieve the optimal balance between production efficiency and quality.

There are numerous types of fiber optic connectors, such as SC, LC, FC, ST, MPO, and E2000. These differ significantly in their dimensions and end-face structures, requiring specialized fixtures for polishing. Traditional equipment often only supports a select number of mainstream models, requiring companies to replace equipment or make complex adjustments when producing multiple models, increasing production costs.

The Fiber Optic Polishing Machine's design addresses this pain point and offers customized fixture services:

• Multi-Interface Compatibility: Customized fixtures can be customized to accommodate different interfaces, enabling multiple uses with one machine and reducing equipment investment.
• Guaranteed Precision: High-precision CNC machining ensures stable positioning of the fiber during polishing, effectively preventing eccentricity and endface unevenness.
• Quick Changeover: The modular fixture design allows operators to replace fixtures in minutes, significantly improving production flexibility.
• Mass Customization: For large-scale production, manufacturers can customize multi-station fixtures based on the specific characteristics of their production lines, enabling simultaneous polishing of multiple fibers and increasing production capacity.

Customized fixtures not only address compatibility issues but also help companies achieve a balance between "small batches with multiple models" and "large batches with a single model," significantly improving equipment utilization.

During fiber end-face processing, the choice of polishing film grit size is crucial. Coarse-grained films are used for initial finishing, removing end-face irregularities and scratches; fine-grained films are used for fine polishing and final polishing, ensuring the fiber end face achieves ideal optical performance.

The Fiber Optic Polishing Machine supports flexible combinations of polishing films with various grit sizes:

• Coarse-grained films (30μm, 15μm): Used in the initial stage to quickly trim the fiber end face and remove burrs and cracks caused by cutting.
• Intermediate-grained films (9μm, 6μm, 3μm): Gradually refine the end face, reduce surface scratches, and ensure smoothness.
• Fine-grained films (1μm, 0.5μm, 0.3μm): Achieve high-precision mirror polishing, ensuring a smooth, defect-free end face that meets low insertion loss and high return loss requirements.

This multi-stage process not only ensures fiber end face quality but also extends the life of the polishing film. Operators can flexibly adjust polishing steps and film grit combinations based on different product standards (such as PC, UPC, and APC end faces) to achieve the optimal balance between cost-effectiveness and quality.

With the rapid development of industries such as 5G, FTTx, data centers, and optical sensing, the demand for fiber optic connector quality and production capacity is becoming increasingly stringent. The Fiber Optic Polishing Machine, with its flexible customizable fixtures and a variety of polishing film grit sizes, not only meets the production needs of diverse scenarios but also provides companies with higher yields and lower operating and maintenance costs.

In the future, with the introduction of automation and intelligent technologies, fiber optic polishing machines will further integrate AI detection and big data analysis to achieve real-time monitoring of end face quality and predictive maintenance, helping companies gain an advantage in the fiercely competitive market.
