# Industrial Specification: Centering Mechanism

## 1. Technical Definition
A precision alignment component within a lens chuck assembly that ensures optical elements are positioned concentrically with the rotational axis.

## 2. Engineering Reasoning & Causal Matrix
> **Operational Intelligence**: Designed for **0.5-2.0 μm radial runout tolerance at 3000 RPM**. Failure boundary: **3.5 μm radial displacement from rotational axis at operating speed**, Mechanism: **Centrifugal force exceeding spring preload (F_c &gt; kΔx) where F_c = mω²r, causing loss of concentricity**.

### 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.
