Component Specifications

Definition
A critical component in precision fiber optic polishing machines designed to securely hold and position optical fiber connectors or ferrules during the polishing process. It ensures consistent alignment, pressure distribution, and stability to achieve the required end-face geometry and surface finish for optimal light transmission.
Working Principle
The fixture plate operates by providing a rigid, flat mounting surface with precisely machined locating features (pins, slots, or clamps) to hold fiber optic connectors. It interfaces with the polishing machine's motion system, maintaining perpendicularity and consistent pressure during the abrasive polishing cycle to create uniform, defect-free fiber end faces.
Materials
Typically made from stainless steel (e.g., 304 or 316 grade) for corrosion resistance and dimensional stability, or aluminum alloys (e.g., 6061-T6) for lightweight applications. May include hardened tool steel inserts for wear resistance at contact points.
Technical Parameters
  • Flatness ≤0.005 mm
  • Thickness 10-25 mm
  • Load Capacity Up to 50 kg
  • Surface Finish Ra ≤0.4 μm
  • Mounting Hole Pattern Grid spacing 25 mm or 50 mm
  • Operating Temperature 10-40°C
Standards
ISO 10110, ISO 1101, DIN 876

Engineering Analysis

Risks & Mitigation
  • Misalignment due to wear or contamination
  • Thermal expansion affecting precision
  • Corrosion in humid environments
FMEA Triads
Trigger: Accumulation of polishing debris on mounting surfaces
Failure: Poor fiber alignment leading to uneven polishing and increased insertion loss
Mitigation: Implement regular cleaning protocols and use protective covers when not in operation
Trigger: Material fatigue or stress from repeated clamping cycles
Failure: Loss of flatness or dimensional stability, causing inconsistent polish quality
Mitigation: Use fatigue-resistant materials, apply periodic flatness verification, and follow torque specifications during assembly
