# Industrial Specification: Polishing Head Assembly

## 1. Technical Definition
A critical assembly in fiber optic polishing equipment that holds and applies controlled pressure to the fiber connector during the polishing process.

## 2. Engineering Reasoning & Causal Matrix
> **Operational Intelligence**: Designed for **0.5-2.5 bar (7.25-36.26 psi) polishing pressure range**. Failure boundary: **3.0 bar (43.51 psi) sustained pressure causing permanent deformation of the diaphragm spring**, Mechanism: **Plastic deformation of the spring steel (AISI 1075) diaphragm due to exceeding the material's yield strength of 620 MPa**.

### 2.1 Analytical Physics Model
Governed by the **Harmonic Vibration Force Generation**:

> **Primary Equation**: $F_e = m \cdot r \cdot \omega^2 \sin(\omega t)$  
> **Engineering Impact**: Calculates centrifugal force for vibratory sifters/feeders.
